Emergency Planning for the Protection of

Cultural Heritage

David Alexander University College London

The risk of disaster may be small, but it is not insignificant....

Cultural heritage: • works of art • works of architecture • museums and galleries • highly prized landscapes • archaeological sites • libraries and archives • storage facilities, etc.

Categories of artefact at risk: • paper, papyrus, etc. • ceramics, glass • metal, stone • leather, hide and parchment • other organic substances: bone, wood, hair, horn, ivory, shell • photographic film (and colour slides) • magnetic media • paintings on canvas or wood • sculptures and bas reliefs • textiles: fabrics, clothing & accessories.

Cultural heritage is particularly vulnerable to a series of risks...

The principal risks: • floods and landslides • meteorological extremes (storms, heatwaves, cold waves, snowfalls) • seismic or volcanic events • fires • infestations • events of human origin (explosions, release of toxic substances, etc.).

Architectural works may be vulnerable to: • structural damage • collapse • the effects of water • damage caused by wind • fire damage • humidity • accelerated decay • fissuring and cracking • damage to surfaces and façades • loss of architectural details, statues, ornamentation, etc.

• very sensitive to extremes of temperature and humidity

• require controlled environments in both exhibition and storage

• can be ruined by structural collapse, fire, flood or explosion.

Works of art:

• overturn objects on shelves

• throw them off shelves to break on the floor beneath

• cause pictures to fall off walls

• Works of art must therefore be firmly restrained against these risks.

• Catalogues must be protected and duplicate copies kept at separate sites.

Earthquakes can:

Seismic risk: • total or partial collapse; serious, moderate or light cracking • failure of foundations • objects overturned or fallen, possibly smashed, as a result of strong motion • objects crushed by the collapse of structural elements or fitments • effects of post-earthquake fire • risks to the occupants of buildings.

Some critical temperature values:- • books and documents: 175 deg. Cent. • tapes, disks, microfilm: 75 degrees • diskettes: 55 degrees.

Tourism:

• the greatest industry ever

• generates 1 in 9 jobs in the whole world

• value: US$3,800,000,000,000

• 262 million jobs associated with it

• 10.7% of world's gross product

• fickle and highly seasonal: with 1 to 3 peaks per year.

How to classify risks: • by environment and location • by category of cultural good • by type of likely damage (vulnerability) • by agent of risk (hazard) • by nature of emergency intervention

Hazard x vulnerability [x exposure] = risk

• Works and sites tend to be fragile, complex and exceptionally vulnerable to disaster

• They form a category that requires special protection against disasters

• emergency management could require considerable resources, but it is usually much cheaper than restoring damaged objects and sites

• without adequate protection a priceless and unique heritage could be lost.

Emergency planning for cultural heritage sites

and artefacts

A distinction can be made between measures to take for objects and sites: • galleries • museums • libraries and archives • storage facilities.

Risks may affect both objects and their settings.

Sites of cultural importance

For works of architecture, archaeological sites, high-value

environments, historic gardens, etc.: compile a list, subdivided by category, age and function.

Protection:

• strategies to follow before disaster strikes (with warning processes)

• recovery and reconstruction works to conduct after disaster

• use impact scenarios to plan operations before crises occur

• maintain a register of cultural goods, procedures to follow and requisites for ensuring their security.

Essential measures:

• study the vulnerability of sites and their contents

• codify the propensity to suffer damage

• organise measures to counteract damage - fire suppression systems - physical barriers against the movement of fire or water - structural reinforcement, buttressing

• involve international organisations (UNESCO, ICOMOS, etc.).

Strategies:

• make an assessment of the situation

• conduct a census of works in relation to the hazards that threaten them

• where appropriate, add a section to the general emergency plan (of the region, municipality, etc.) on the procedures employed to save cultural heritage.

Strategies:

• form task forces and give the members accreditation

• in a crisis or during an alert, they will need to pass security systems rapidly to reach works at risk.

We need to adopt a systematic approach to emergency planning:

"thinking the unthinkable", anticipating the improbable.

Emergency procedures

Emergency co-ordination

plan Spontaneous improvisation

The plan: • foresee the foreseeable, design measures • create the structure to apply procedures.

Actions to take before disaster strikes - prevent and limit future damage.

Actions to take when disaster strikes - save and secure cultural goods.

Emergency planning: • construct scenarios of possible impacts • establish priorities for saving particular works • work out who will do which tasks • constitute task forces • establish procedures for getting through security • create a system of monitoring and warning.

Another fundamental aspect: preserving the catalogue and identifying objects that have been saved.

Planning procedures:

• conservation of catalogues and records

• involves curators and custodial staff

• in an emergency accredited rescuers must be able to pass through security systems rapidly and without hindrance

• procedures are needed to open galleries and museums to rescuers when an emergency is imminent or happening.

• arrange means of lifting, protecting and transporting objects (which may be heavy or unwieldy) to safe places

• organise procedures that guarantee the safety of cultural heritage goods in places to which they are evacuated

• establish priorities for locating, transporting to safety and carrying out works of protection or restoration.

Planning procedures:

Protection:

• decide whether to protect artefacts in situ or move them to a safer place

• establish priorities for each artefact on the basis of its importance and ability to protect it or procedures needed

• assign rescue squads to each task.

Methods of in situ protection:

• sandbags, protective covering, etc.

• requires stockpiling of materials and study of: - methods of assembling protection - organisation of work-groups.

Measures:

• analyse risks by type of event or situation

• structural retrofitting of buildings

• arrangements for evacuating occupants

• attach display cases to walls

• other protection measures.

Organisation of in situ operations:

• how to open cabinets, store-rooms, etc.

• how to dismantle or detach the works

• how to use equipment for lifting and transporting the works

• stockpiling appropriate containers.

Organisation of transport for artefacts:

• the route to take for each load

• means of transport

• characteristics of the storage place: - custodial matters, security, control of indoor climate, hazard mgt, etc.

• how to pass through security systems.

Tackle the problem of insurance for works of art, etc., in situ, in transit, in storage.

Create a register • of artefacts and places in terms of protection strategies and how they will be activated in a crisis • of the associated risks.

Evaluate the probable nature, seriousness and extent of likely post-disaster restoration works.

Training for museum directors, managers, curators, custodians and other personnel

• in emergency procedures • in recovery methods that will probably

be needed after an expected crisis

... and discuss with them the scenarios of hazard and impact.

• susceptibility to damage and losses

• particular or evident signs of weakness or decay.

Subject every high-value building or site to an assessment of its vulnerability to disaster

Suggest mitigation measures: • fire-suppression systems • physical barriers • structural bracing • buttressing, etc.

No historic building need necessarily be demolished merely because it is susceptible to damage in a disaster,

however, retrofitting to appropriate levels of protection could be very expensive.

Before disaster strikes:

• where possible, estimate the probable restoration needs--i.e., the vulnerability of the building

• identify sources of wood and scaffolding or stockpile these items

• identify appropriate professionals and reputable specialist building firms.

Possible sources of help for reducing the vulnerability to disaster of cultural heritage:

• national, regional and local civil protection departments and public works ministries or departments

• International Council on Monuments and Sites (ICOMOS), Paris

• United Nations Educational, Scientific and Cultural Organisation (UNESCO), Paris.

Some protection procedures: • lift and move objects to places located outside the risk zone • wrap up, remove and take away from the risk or impact zone • protect in situ (wooden panels, sandbags, etc.) • consolidate (scaffolding, buttressing, etc.).

Procedures: how to.... • open secured doors • disactivate alarm systems • authorise access to protected places • verify the identity of rescue squads and their members • open display cabinets • remove works from walls • wrap up works in protective packaging • safely move heavy, unwieldy and fragile objects.

During an emergency: • stabilise the situation • recover, save and protect objects • rehabilitate areas of cultural significance • transport mobile cultural goods to places of safe storage • safeguard catalogues and preserve the means of identifying artefacts • seek to restore normal conditions.

TASK FORCES

When a crisis occurs and the emergency plan is activated....

• Not all cultural heritage takes the form of tangible assets: e.g. genius loci (sense of place and sense of belonging)

• The heritage sector does not understand the language of disaster risk reduction and is not implementing DRR to a significant degree

• heritage is seen as taking a passive and secondary role in disaster risk reduction.
