Conservation

Hanging is not too good for them…

Tuesday, October 27th, 2015

The Polar Museum has almost 3000 artworks including masterpieces by Edward Wilson and David Smith.  The majority of these are unframed and kept in dark storage. However, we do also have some framed artworks which we keep in compact mobile racking in the store:

photoracking     photo racking

The framed art is hung on grids with hooks, which keeps the pictures from banging into each other and damaging the frames.

A lot of these works are oil and acrylic paintings, but a recent audit showed that there were also quite a lot of engravings and other works of art on paper, framed and hanging in the mobile racking.  These works are much more light sensitive than the oil paintings and really should be kept in the dark as much as possible.

Another problem is that some of the frames are really old and might actually disintegrate and fall off the racking, which would be bad for the pictures, to say the least!  Here is a very dodgy looking screw fixing on the back of one picture:

And the paper tape around the back is sometimes so old it just crumbles away:

Our recent risk assessment, carried out with the help of colleagues from the UCM, showed that tackling these problems should be a conservation priority. So we have started a project to improve things for the vulnerable artworks by taking them out of their frames and finding better homes for them in dark archival boxes.  It is simple but satisfying work, especially when it is obvious that the artworks will immediately be better off out of their frames.  For example, this looks like a piece of plywood:

plywood

But actually it is the back of a paper artwork (a lithograph) showing birds!  If you look closely you can even see the “ghosts” of two birds in the wood grain pattern on the paper.  The front of the picture looks like this:

birds

Unusually, the framer put the wooden back of the frame directly over the paper rather than using a cardboard mount, and the acid in the wood has discoloured the artwork on the back.  Over time this would eventually penetrate through to the front and ruin the image.  Already the acid damage has made the paper rather yellow and unusually brittle.

Some frames are beyond saving, but many of them are kept in the attic so we can re-unite the frame and artwork in the future if we want to.  This is especially important for original paintings and drawings where the artist themselves chose the frame.

We keep the frames in tough padded bags called Stiffy Bags, which we order in various sizes.  You can see from the size of the Stiffy Bag delivery that I will be deframing art and packing frames for quite some time!

Condition assessing in the Antarctic

Tuesday, October 13th, 2015

Last week, Sophie and I spent a day training a team from the United Kingdom Antarctic Heritage Trust. UKAHT “works to conserve Antarctic buildings and artefacts, and to promote and encourage the public’s interest in its Antarctic heritage“; among other things, the Trust generously supports our Conservator post at the Polar Museum. The work they do is fantastic, so we are always pleased to help them where we can!

Port Lockroy was a British Antarctic Survey base until 1962, and was renovated in 1996 to return it as far as possible to its original condition. The base is now maintained by UKAHT as a historic monument under the Antarctic Treaty and receives about 18,000 visitors each year. Each year a team of four people is recruited to live and work in Port Lockroy during the summer season (November to March). The team will be incredibly busy during their time there, maintaining the buildings, monitoring the local gentoo penguin colony, welcoming visitors to the site and museum, and running the gift shop and post office among other things!

This year’s UKAHT team – Rachel, Iain, Laura and Adele – will be also be carrying out a new task: beginning a condition survey of the 2000 objects that are in Bransfield House, the main building on the base. Many of these objects date from the 1950s and are both historically significant and irreplaceable. It’s very important, therefore, to monitor their condition and conservation needs, to ensure that they can be cared for appropriately.

Sophie and I were asked to help design a condition survey that could be taken out to Port Lockroy and carried out by the team this season. It would be impossible to cover all 2000 objects in the four months that they are there, so we selected a sample of 200 objects to begin with. This includes all of the most significant objects, plus a random selection from among the rest – anything from an entire cooking range to a single spoon:

The first batch of survey objects also includes a radio receiver, a fire bucket, books and records from the lounge, clothing, bottles of ink, skis, portraits of the Queen and Duke of Edinburgh, a bar of Lifebuoy soap, a generator…

With such a range of materials and objects involved, UKAHT asked the Polar Museum conservators to provide training in how to assess condition and record damage. Three of the Port Lockroy team came to the Polar Museum last week, and spent the day learning how to handle objects:

PhotoGrid_1444754672815

and examine them for signs of deterioration:

PhotoGrid_1444388692201

After lunch, the team did a practice condition survey with some of the Polar Museum’s objects, so they could get used to filling in the form. Consistency can be difficult with condition surveys, especially where there are several people doing the assessment. Your perception of how serious damage is may be wildly different from your colleague’s – or even from your own results last week (there is lots of evidence to show that judgement is affected by how tired, or hungry, or grumpy you are)! We tried to limit these inconsistencies by providing training in how to rate object stability, and also by giving the team a manual with lots of notes and photographic examples in it. We also tried to make the form quick and easy to fill in; Bransfield House is luxurious by Antarctic standards (between 4°C and 15°C during the Austral summer), but it’s still not much fun trying to write in those temperatures!

Adele, Iain, Rachel and Laura will be going South on 7 November. You can follow their progress on the Port Lockroy blog. We wish them all the best for their season, and look forward to hearing how they get on with the condition survey!

It’s freezing!

Tuesday, September 29th, 2015

Our museum contains objects made from many different materials, including fur, textile, leather, wood, plastic and metal. Many of these materials, especially the furs and textiles, are susceptible to insect attack from moths and some varieties of beetles, such as the vodka beetle, and our best defence against them is FREEZING COLD. Often the insects might not themselves be visible, more often we see the surface evidence of insect activity only, such as bald patches where they have been grazing, frass (droppings), cast skins, or larval cases.

OLYMPUS DIGITAL CAMERA

It is almost impossible to eradicate such pests from an old building like ours so we maintain a check of the situation by using small sticky traps placed at strategic points throughout the building which are regularly inspected:

image2 image3

However, monitoring and trapping is not failsafe – outbreaks of infestation can happen. Cracks, vents, and drains all give insects access to every part of the building and this includes the basement where the museum stores are located. Once in, if they find the food they are looking for they can quickly spread and, unchecked, can cause irreparable damage in a matter of only weeks:

image4 image5

Low temperature control is an established technique used to kill insects within museum collections. Cooling a room below +15 ºC can slow or stop the growth, feeding and breeding of museum insect pests, but subjecting them to temperatures of lower than -20ºC will eradicate the insects, their larvae and eggs for good.

At The Polar Museum, our practice is to routinely freeze all organic material coming in from outside the building even if no pest is evident, unless the items are felt to be at high risk of damage from freezing – we do not want to risk the infestation of an object spreading to the rest of our collections. This is the procedure for not only new acquisitions but also for our own objects when they are returned after having been on loan to another museum for temporary exhibition, as we cannot be one hundred percent certain they have not been exposed to pests whilst away. The objects are wrapped in clear polyethylene and sealed with tape before freezing. We wrap them not only to immediately contain the potential infestation, but also to prevent moisture changes in the object during freezing which could result in possible dimensional changes which can cause cracks, for example. We are very fortunate in that we have on the premises a walk-in room sized cold room, which can be set to a very chilly -34 ºC. No pest yet discovered can survive a week at this temperature!

image7

We have many materials within our collection that could be damaged by freezing temperatures, such as rubber (in goggles and footwear), liquid (medical supplies, including thermometers and pharmaceuticals, and high precision scientific instruments such as compasses) oil paint and varnished objects. These objects cannot be frozen, and so instead are wrapped in polyethylene and returned to the stores and monitored for any tell-tale sign of pest activity.

On occasion we have been able to help other museums in Cambridge who do not have the luxury of a walk-in cold room as we do. Recently we were approached by Kettles Yard, an art gallery and house, who are currently preparing for a major building project to improve and build upon their education and gallery spaces. Whilst in the process of packing and moving the collections for safekeeping during the building work, they discovered a number of live moths emerging from some of the textiles, specifically from a collection of rugs, and contacted us immediately for help! Luckily the cold room was not being used so we could offer to freeze all of the affected objects – a total of 25 large rugs- in one batch. They arrived a few days later, with the rugs all tightly wrapped and labelled, and we set about navigating them through the building and down three flights of stairs to stack ready for the cold room.

image6

Walking into a freezer set at -34 ºC is not without risk, however – hypothermia can lead to death, so whilst the risk of something going wrong is low, the severity of the situation if it did, would be major. Accordingly, lone working is never to be undertaken, and we have procedures in place for staff use of the cold room to ensure risk is mitigated. External users are given induction training in the safe use of the cold room and are asked to read and sign a risk assessment. Warm clothes, sensible shoes and gloves are to be worn. As an extra safety precaution, we must have a ‘buddy’ elsewhere in the building who knows what time we enter the cold room, and what time we expect to be out. If we have not reported back by the pre-arranged time they must come and check we haven’t managed to slip, knock our heads together and pass out in the freezing temperatures. Hypothermia is not something we take lightly, here at The Polar Museum.

image8

The freezing of the rugs from Kettles Yard went well. After a week and a half (for good measure), Sophie and I braved the cold again and removed the frozen rugs from the cold room, laying them in the basement, still wrapped, to slowly come back up to temperature. Another success in the battle against infestation! RIP, museum pests.

Time to put on a hard hat….

Tuesday, September 15th, 2015

During the recent refurbishment of the front of the Institute, I took advantage of the scaffolding to go up and have a closer look at the bronze bust of Scott in a stone alcove above the front door.  It is very rare to have such good access to this sculpture and I wanted to see what sort of condition it is in. So with hard hat and hi-vis vest on, I went up to have a look:

20150827_153227       photo8

The bust is by Scott’s wife Kathleen and has been on the front of the Institute building since 1934.  Kathleen was a professional sculptor, and it is easy to see that she worked with Auguste Rodin (who was actually a guest at her wedding to Scott).  Her style of modelling skin and cloth owes a lot to Rodin – here is a picture of his bust of Jean d’Aire, one of the Burghers of Calais, alongside the Scott bust for comparison:

        photo7

When seen close up, the bust of Scott is twice life size and looks almost alarmingly craggy!  The sculpture was designed to be seen from far away, so the features are deliberately very exaggerated so they would be visible from the ground – right down to the big wart on Scott’s top lip:

photo3

The bust is in pretty good condition considering it has been out in all weathers for over 80 years.  The surface is patchy and green but the corrosion is not damaging or out of control – many sculptors even deliberately treat the surface of bronzes to achieve this effect.  The bust is screwed to a solid core with a huge bolt:

photo6

It is also sitting in a nifty lead tray which catches rainwater running off the surface. This water can be coloured green from the corrosion on the sculpture, and if it just flowed off the bust onto the stone below it would cause a big green stain on the building.

Pigeons are damaging for metal sculptures because their droppings can accelerate corrosion of the metal.  Luckily there were just a few droppings round the sculpture and it doesn’t look like any pigeons have ever nested on Scott’s head.  Perhaps his hood is too pointy for them to get comfortable! I removed the droppings with stiff brushes, and also cleared out the space behind the bust which was full of dead leaves etc.

20150827_153021

While up on the scaffolding I also enjoyed a unique close-up view of the lovely 1930s stone carvings over the windows which match the pillars inside the Memorial Hall behind – a mother and baby penguin for the South Pole and a polar bear for the North:

Hello to Ronja!

Friday, September 4th, 2015

This week we welcomed a new conservation intern to the Polar Museum!

Ronja

Ronja Fröhlich has joined us from the University of Applied Sciences (HTW) in Berlin, where she is studying for a degree in the conservation of modern materials. Before she started her degree, she did a year-long internship, working partly with a conservator in private practice, and partly at the film museum in Potsdam, treating objects as diverse as film projectors, photographs and a Hastings aeroplane from the late 1940s! Since then, she has worked on a new display at the Gedenkstätte Berlin-Hohenschönhausen, a memorial on the site of a former Stasi detention centre in East Berlin, as well as a variety of nineteenth- and twentieth-century objects and vehicles.

Ronja will be with us for three months, working alongside the conservators on a range of projects. She has already been busy carrying out our quarterly inspection of pest traps around the Museum and Institute buildings, and next week she will begin rehousing our extensive (and diverse) collection of goggles. After that, we will be drawing on her expertise in modern materials when we assess the condition of our scientific collections at the Polar Museum. Here she is discussing conservation adhesives with Sophie, in our conservation lab:

Sophie and Ronja

We’re really looking forward to having Ronja with us for the next few months. She will be posting about some of these projects on the blog soon!

So Fargo, so good…

Tuesday, August 25th, 2015

The Wells Fargo Museum in Anchorage has a fantastic collection of artefacts made by the native peoples of Alaska, including the Aleut, Athabascans, Tlingit, Inupiat and Yupik. These groups have a very varied and beautiful material culture, and we are excited to be borrowing a large number of objects made by these people from the Wells Fargo Museum for our special exhibition in the summer and autumn of 2016.

Organising a loan exhibition when the lending museum is on the other side of the world brings its own challenges. Not the least of these is that a lot of historic Alaskan native artefacts are made using animal material covered by CITES laws on the trade in endangered species. This means that many of them have to have special licences to travel to the UK. Arranging these is a complex task for Willow!

The Wells Fargo Museum (which has a wonderful-sounding address on Northern Lights Boulevard, Anchorage) very generously gave us a choice of over 100 artefacts to borrow. But we only have room for about half that number in our show cases, so we had to choose. We only want to bring over the objects we can show and no more, since transporting museum artefacts round the world is risky for them, not to mention complicated and expensive.

The exhibition is being curated at the Polar Museum by the delightful Larry Rockhill, a SPRI Emeritus Associate and expert in Alaskan art:

Image of person

Using database printouts from Wells Fargo, Larry drew up a shortlist of the objects he wanted to tell the stories in the exhibition. Then we set about checking how many we have room for – the old-fashioned way.

I measured the footprints of all our display cases and shelves, and then taped these out with masking tape on a huge table in the Map Room. Next, using measurements from the Wells Fargo database, I cut out paper footprints of all the objects on the shortlist so we could see how much room they would take up on display. Then Larry and I arranged all the object footprints inside the display case footprints. We didn’t have room for everything, but this process helped us narrow the list down further and work out which objects were most important.

IMG_20150521_123924387_HDR  IMG_20150521_123930430

While we were looking in detail at how the objects will fit in the cases, we were also able to work out which ones will need display mounts. I am particularly excited about a group of prehistoric animal and human figures made from ivory, which are thousands of years old. They are all very small and so will need to be displayed thoughtfully to bring out their understated beauty.  This is a similar ivory carving recently sold at Sotheby’s – it is 2000 years old and just over 5 inches high.

N08386-74-lr-1.jpg.thumb.385.385

Now that the object list is finalised, we can go ahead and arrange transport to the UK – with any luck there is still plenty of time to do all the paperwork before next summer…

All things Shackleton…

Friday, August 14th, 2015

SPRI P66/18/36. Frank Wild (left) and Ernest Shackleton (right).

This year we are in the midst of commemorating the centenary of the Imperial Trans-Antarctic Expedition 1914–17 (Endurance and Aurora), led by Sir Ernest Shackleton. It’s a tale that hardly needs retelling: Shackleton and his men survived one of the worst disasters in Antarctic history – their ship was crushed and sank, and they were forced to make an open boat journey to Elephant Island where they lived for over four months before they were rescued.

With just under six weeks to go until the opening of our new exhibition, By Endurance We Conquer: Shackleton and his Men, we’ve got Shackleton very much on our minds. The exhibition will commemorate all the men that sailed with Shackleton aboard the Endurance, and will also honour the Ross Sea Party (three of whom lost their lives), which laid the supply depots for the planned crossing of the Antarctic continent. This week saw the arrival of some of the objects we’re borrowing for the exhibition, including a pannikin which belonged to Shackleton himself and is marked with his initials, ‘E.H.S.’, and a yachtsman’s cap belonging to James Mann Wordie, expedition geologist.

New arrivals for By Endurance We Conquer: Shackleton and his Men

New arrivals for By Endurance We Conquer: Shackleton and his Men

We’ve spent several months drawing together information about all of the men from the Endurance expedition to create biographies for use in the exhibition and in touch-screens in the galleries. And we’ve just launched a volunteer project to put these biographies (and others) into our database, which has proved highly popular and has had an impressive sign-up.

However, we’re not just concerned with the Endurance expedition – our Shackleton focus extends to his other expeditions: the British National Antarctic Expedition 1901–04 (Discovery), led by Captain Robert Falcon Scott; the British Antarctic Expedition 1907–09 (Nimrod); and the Shackleton-Rowett Expedition 1921–22 (Quest), on which Shackleton died.

In 2014 SPRI received a generous grant from the Heritage Lottery Fund for By Endurance We Conquer: The Shackleton Project, which will unite the collections at SPRI (Archive, Museum, Library and Picture Library) through new acquisitions and interpretation of material relating to Sir Ernest Shackleton.

The museum collection contains material from all of Shackleton’s expeditions, including foodstuffs, goggles, medals and a thermometer from Nimrod; and crampon shoes, a sledging flag and a clock from Quest; as well as boots, Shackleton’s goggles, and the sextant used by Worsley during his extraordinary feat of navigation on the crossing from Elephant Island to South Georgia. Over the past few weeks as part of the Antarctic Cataloguing Project, we’ve been looking carefully at all of these objects and getting them photographed in order to produce detailed records for our forthcoming online catalogue. We’ve also been condition assessing them to highlight any future conservation needs. In addition, the education and outreach team have been working to create new Shackleton-related educational resources and a programme of events.

The Archives contain Shackleton’s diaries from all of his expeditions, as well as correspondence, lecture notes, poetry and papers written by Shackleton himself and his wife Emily. The collection also includes the diaries and papers of members of Nimrod, Endurance and Quest expeditions. These are currently being added to the database so that they will be a searchable resource in the future.

By Endurance We Conquer: Shackleton and his Men will open on Tuesday 22 September 2015 and run until 18 June 2016. To find out more about events commemorating the centenary of the Endurance expedition at SPRI and across the world, take a look at the Shackleton 100 website.

After the flood: dehumidifiers and drainage

Thursday, July 30th, 2015

Last week, I wrote about the flood that affected our basement stores following a sudden and violent thunderstorm. As I said then, the initial response went very smoothly, and we were able to clear all of the standing water out of the basement within a couple of hours. We didn’t stop there, however!

A flood can continue to be a problem for museum collections even after all of the water has been mopped up, and even if none of the objects got soaked directly. Having water all over the floor will raise the relative humidity (RH) of a room significantly, and if the water is not removed quickly and thoroughly, the humidity can stay high for days. An RH over 65-70% is enough to grow mould in the right conditions, especially for objects that have been affected by mould in the past.

The graph below shows data from our main basement store before and after the flood (click on the picture to see a larger version):

MSA

The point marked A (about 3.30am) is when the flood waters entered our basement; you can see the RH jump sharply from 55% to 65%. At this point, the water had only penetrated a couple of metres into the storeroom (despite covering the whole floor in other rooms), so you can see that even a little bit of water can make a big difference to the environmental conditions.

Point B is at 8am on the same morning, when the museum team started clearing water out of the basement. The RH falls over the following few hours, until it is back around 55%, which is where we would like it to be. Some of the fall in RH is because we pumped out all the standing water, but some of it is due to this machine:

15

This is a portable dehumidifier, and is one of the most useful bits of equipment we have in our stores. If we spot that the humidity is creeping up in one of our storerooms, we can move the dehumidifier in there and run it until the humidity is back within the safe range. We left it running for a few days in the main store, and it helped dry out the room completely.

In areas that had been more severely flooded, a more aggressive approach was needed. Even though we’d mopped up all the water from the floors, there was water trapped underneath cupboards and shelving, as well as in the atmosphere. We hired industrial dehumidifiers and ran them continuously to dry out these areas as quickly as possible.

The dehumidifier below (in the Library’s Map Room store) has an external water tank of 20 litres (about 4.5 gallons). While the room was drying out, the tank filled up completely every couple of days – that’s a lot of water that we were removing from the atmosphere!

16 17

To monitor the drying process, I moved one of our Eltek transmitters into the Map Room:

18

This transmitter collected information about the temperature and RH every half hour and sent it to my computer in the museum office. The data was displayed on a graph like this one (again, you can click on the image to see a bigger version):

Map Room 2

Point A is when we moved the dehumidifier into the Map Room and started monitoring the environment. The RH was 70% at that point – definitely not good news for the collections! After a week, the humidity had settled down and was in danger of becoming too low (point B), so we switched the dehumidifier off and waited to see what would happen. The only way to tell if an environment is stable is to turn everything off and see what happens without the dehumidifiers, heaters or fans. After a few days, the RH had crept back up to 60% again (point C), so we turned the dehumidifier on again to remove the last few bits of moisture from the room. Our basement stores are now all stable once more, and we’ve avoided any secondary damage to objects from the flood.

Mopping up was not confined to the inside, however! Outside the Institute is a try pot (a metal cauldron used in the whaling or sealing industries). The thunderstorm dislodged so many leaves and twigs from the tree above that the drainage hole drilled in the bottom became blocked and the pot filled with water. The result was a rather unpleasant stagnant, leafy soup.

The picture below shows Grahame with a “wet vac” – it’s exactly like the vacuum cleaners that we all have at home, but is designed to suck up water as well as dirt.

12

Grahame used the wet vac to remove all the water from the try pot, and then cleared out all the leaves so it could drain freely again.

11 13

The try pot is now lovely and clean once more, and everything is back to normal after the flooding. I think we can say that we well and truly weathered that storm, and are (hopefully) well prepared for the next one…

Welcome home!

Thursday, July 23rd, 2015

Note: I intended to publish this last week, but events on Friday overtook us and this post was put on hold. Still, it’s better late than never!

Monday was a bit of a red letter day at the Polar Museum, as it saw the return of many of our objects from a very long touring exhibition, Race to the End of the Earth. Since opening in 2010, the exhibition has had tens of thousands of visitors in five venues. In a journey almost as epic as Captain Scott’s expedition to the South Pole, our objects travelled from Cambridge to the American Museum of Natural History (AMNH) in New York, then on to the Palazzo Ducale in Genoa, the Royal British Columbia Museum in Victoria, the Museum of Idaho, the Musée des Confluences in Lyon, and finally back to Cambridge, where we welcomed them back this week.

Normally it’s a safe bet that what comes back to your museum after a loan is the same as what left it … but not in this case.¹ This touring exhibition had slightly different displays at each museum, so each time it moved to a new venue, some objects came back to us and others went out on tour. Sometimes this was because of practical constraints at a particular venue, but other times it was for conservation reasons. Display for long periods can be damaging to museum objects (which is why we have a programme of regular rotation for the most sensitive objects in our collections). Touring exhibitions can cause additional wear and tear, either through prolonged exposure to light, or just from the handling, packing and mounting that is necessary for an exhibition, so it is common for fragile objects to be swapped in and out so they can be “rested”. Like people, objects sometimes benefit from a long lie-down in a darkened room!

A unexpected complication from all this swapping was that our objects went out and came back in different crates. We discovered after unloading that the new crates would not fit through this door (which has access to the lift down to our basement store)!

backdoor   lift

Luckily, we managed to muster enough strong chaps to carry the crates up the front steps of the Institute and into our temporary gallery, where we roped off an area for unpacking and condition checking:

overview   photography

(These pictures are for anyone who has ever wanted to see inside a shipping crate. They contain a lot of foam to ensure that the objects inside have a smooth plane/boat/lorry ride. This crate only contained three modest-sized boxes of objects, and the rest was polyethylene foam!)

crate

I was excited to see that one of the boxes inside contained knitwear belonging to Edward Mackenzie, a stoker on Scott’s Terra Nova expedition. I became interested in these mittens and their construction while documenting them before they went on tour, and concluded that they were made from a stitch called fisherman’s rib. I knitted a swatch of fisherman’s rib, to see if it would look similar – and it did!²

mittens

I was reminded of all this while condition-checking the mittens, an essential part of any museum loans procedure. Before an object goes on loan to another museum, it is thoroughly photographed and has its condition documented in detail. It is checked when it arrives at the exhibition venue, and again when it leaves and arrives back home. Having good records allows us to spot any changes in condition during transit or display (fortunately, this is very rare), and to work out where in the process they have happened.

The pictures below show both old-style and new-style condition reports:

check   ipad

In the first picture, I am comparing McKenzie’s mittens with the photographs and notes that I made when they first went on tour in 2013. Paper records like this are good because you can write on them easily, and because you can have a single set of documentation that accompanies an object throughout its tour and is then archived. We usually use paper condition reports at the Polar Museum (albeit print-outs of digital reports).

This time, however, we were brought into the 21st century! Jenn, a registrar at AMHN, has accompanied the touring exhibition over the last few years and has been the person responsible for shipping, unpacking, documenting and installing all the objects in all its venues. To save her from lugging around a suitcase of paperwork everywhere she goes, she keeps all the loan documentation on an iPad. The digital condition reports can be annotated and even signed just like paper copies (although this is a bit tricky while wearing gloves). Once she gets back to New York, Jenn can e-mail us the annotated digital report, and we can print it out to be filed with our more traditional ones.

Once all the documentation has been done, the objects go into quarantine (in case they have picked up any nasty bugs on their travels), before going back into storage for a well-deserved rest.

Weathering the storm: always be prepared!

Monday, July 20th, 2015

At 7.30 on Friday morning, I got the phone call that no conservator wants: there had been a flood in our basement storage areas and please could I come in as quickly as possible. I went immediately to the station, only to find that the trains between Cambridge and Ely were delayed because of waterlogged track:

1

While I was waiting for my train to arrive, I looked at the news online, to try to find out how bad things might be. There had been a very sudden thunderstorm on Thursday night, and my Twitter feed was full of pictures of giant hailstones, flooded tunnels and dramatic lightning strikes. The local newspaper was reporting closed schools and cancelled operations at Addenbrooke’s hospital. What would I find when I arrived at the Polar Museum???

Actually, there was no sign at all from the front of the building that there had even been a storm:

Inside was a different matter, however:

A drain had blocked at the bottom of a staircase and there was water throughout the whole of the basement. The museum stores are in this area, as well as some of the Library’s reserve shelving and the Institute’s own administrative paperwork. At its deepest, the water was about 8cm – this might not sound like much but is enough potentially to cause a lot of damage.

Luckily, we were well prepared! After a previous flood in the basement, we had made sure that none of our objects were stored directly on the ground. You can see in the picture below that the wooden blocks supporting these objects have got wet, but that the water didn’t reach the objects themselves.

Having objects and storage units raised up like this also helps with drying out areas after a flood. During a flood, the water gets underneath everything, and it can be difficult to get it out from underneath cupboards and shelves. If rooms are not dried out quickly, the humidity goes up, and there is a risk of mould growth or even structural damage to objects.

The plan chests in the photo below (which contain maps belonging to the Library’s collections) have been raised up on wooden battens, and this ensured that the water didn’t reach any of the drawers. The battens have holes cut in the bottom to allow water to flow out from underneath the chests; it continued to seep out for hours after we had dried the floor!

We were also well prepared in terms of equipment and training. The grey “sausages” that you can see in this picture are absorbent “booms” that you can use to block and divert flows of water. They won’t contain a full-scale flood, but can often be enough to prevent water from going into a room.

In our basement, we have a large yellow “disaster box” that contains essential materials for salvaging objects in an emergency:

Luckily, we didn’t need to salvage any objects after this flood. We have been working on our emergency plan and disaster preparedness over the last few months, so when our team got the phone call to say that there had been a flood, everyone knew what to do. Because we were well prepared, the response to this incident went smoothly and there was no damage to the historic collections. By the time the Institute opened at 9am, everything was under control and we had stopped to have a well deserved breakfast of coffee and croissants!

Of course, the clean-up effort didn’t stop there: the rest of the day was spent mopping up water, cleaning dirty floors and moving objects so we could dry out wet areas. We also had to monitor the environment in the affected areas, to make sure that it returned to normal as quickly as possible. I’ll write more about how we did this in another blog post!
