DISASTER RECOVERY
Disaster Recovery has four principal phases:
- Disaster Response
- Salvage Operations
- Reconstruction
- Disaster Recovery Assessment.
DISASTERS are unusual events that have resulted in injury, property or collection damage, or in the disruption of normal services. A disaster is characterized by the need to institute plans for the salvage and subsequent repair or replacement of property or objects.
If the disaster required the evacuation of the building or neighborhood in which it occurred, only Emergency Services personnel are permitted in that location until the Emergency Services’ Chief hands control of the site back over to its owners. The site should be inspected by an appropriately qualified person ensure that it is physically safe for re-entry. After the site inspector has given the site the “All Clear” for safety, the emergency may be considered to be over, and people may be permitted to re-enter affected areas to commence salvage and clean-up operations.
Disaster Response
Disaster Response is the reaction to, and the elimination of, the emergency (fire, storm water or burst pipe flooding, plant or equipment malfunction, chemical spill, building collapse, earthquake, etc.). After containment and elimination of the emergency, the Salvage Team’s first task is to assess the degree and type of damage incurred and to plan the Salvage Operations. Insurance companies should be contacted at this point.
Salvage Operations
Salvage Operations commence after the Emergency Services Chiefs have handed control of the site back to the owners and the site’s safety has been confirmed. The aim of Salvage Operations is to identify, safely remove, and subsequently clean, repair and/or preserve the remains of objects of high sentimental or monetary value.
Salvage Operations continue on-site until all objects affected by the emergency, and deemed as worthy of salvage, have been removed for storage and treatment. When all items have been removed from the site, reconstruction or building repair can commence.
Salvage Operations continue off-site until the treatment of all salvaged items has been completed. Salvage may overlap with the third phase, Reconstruction.
Reconstruction
Reconstruction begins when all salvageable materials have been removed from the site, and the site has been cleared of all remaining rubble and other materials. Reconstruction ends when every salvageable item is back in its normal location, and non-salvageable but replaceable items have been replaced.
Disaster Recovery Assessment
Disaster Recovery Assessment begins as Salvage Operations on-site end. Disaster Recovery Assessment should cover the full range of Recovery Activities: Disaster Response, Salvage Operations, Reconstruction, and even the Assessment process itself.
The aim of Disaster Recovery Assessment is to identify all the factors which contributed to the disaster, to recognize which activities or procedures helped to minimize danger and damage during or after the disaster and the salvage operations, which activities or procedures were ineffective in minimizing danger and damage during or after the disaster and the salvage operations, where improvements could be made in preventing and reacting to a similar occurrence in the future.
Disaster Recovery Assessment ends after comments and procedures to improve Disaster Response and Recovery have been incorporated as normal working procedures and responses.
SALVAGE PLANNING
The overriding principles for all Salvage Operations are:
- Human safety has precedence over protection and/or removal of objects, including items of tremendous personal or monetary significance.
- The directives of the Emergency Services personnel (who are legally required to take authority in an emergency) are to be obeyed.
GUIDELINES FOR SALVAGE: PROCEDURES
-
Identify the cause and extent of the damage.
- The four principal causes of damage to collection items are water, physical force, fire, and exposure to chemicals. Water and physical forces are the most frequent and the most likely causes of collection damage. Rain, floods, broken sewerage or water pipes, and accidentally triggered fire-sprinkler systems are common causes of water damage. Faulty construction techniques and structural failure through poor design or earthquake are common causes of physical damage. Items may suffer more than one type of damage at a time, e.g. fire, water, and physical.
- In the case of structural failure due to fire, flooding, earthquake, or the collapse of a building or a display / storage structure, ensure that the structural safety of all elements of the salvage site have been checked and cleared by a consultant engineer.
- In the case of chemical damage, identify the chemical, its toxicity, and signs of adverse human reactions to it. Identify all possible reaction products of the chemical, their toxicity, and signs of adverse human reaction to them.
-
Ensure that the environment and structural safety of the building infrastructure has been stabilized before salvage operations commence.
-
If the cause of the disaster was weather-related, contact the Bureau of Meteorology for a local weather forecast for the next 24 hours. Salvage Operations should not commence in the same conditions which caused the disaster.
-
Identify suitable locations for the storage of objects recovered from the disaster site.
-
Assess the character and degree of damage to objects.
-
Ensure that all members of Salvage Teams have been issued with and are wearing appropriate protective clothing and equipment: stout boots or shoes to prevent puncture wounds from broken glass and metal fragments; protective gloves; a wide-brimmed hat for work outdoors; a face mask for dust protection; overalls or loose clothing (long-sleeved shirts and trousers) for dust protection.
-
If there is any chance that the site is contaminated with asbestos, have a professional asbestos removal firm inspect the site prior to beginning salvage work there. If these experts determine that there is asbestos on the site, follow their advice with regard to access to the site and / or the use of breathing apparatus to prevent the inhalation of asbestos fibres.
-
Ensure that each member of the Salvage Team is aware of the team’s responsibilities in the salvage operation and of how their team will work in conjunction with the other teams.
-
Ensure that each member of the Salvage Team has been told, or issued with, lists of objects they should be looking for in their search area. Each member of the Salvage Team should be given a sketch or plans of the contents and layout of rooms in which they will be working.
-
Plan to clear room entrances and aisles first. Unless priorities determine otherwise, begin work from the nearest access point, i.e. work from the doorways inwards.
-
Ensure that all the members of each salvage team are familiar with how to use all the salvage equipment from zip-lock plastic bags through to crates & tables.
SALVAGE PROCEDURES: PRIORITY ACTIONS – SALVAGE TEAM MEMBERS
-
Wear all protective clothing and equipment issued for use whenever you are on the disaster-affected site.
-
Follow the team leader’s instructions, utilizing the sketched floor plans to identify and confirm the correct sequence of salvage.
-
Do not attempt to wipe water, building rubble, dirt, ash, soot, chemicals, or chemical by-products off objects.
-
Do not ever stack salvaged items on the floor or in large piles because this will increase the possibility of physical damage.
-
In cases of water damage: Be aware that wet paper will swell and is both heavier and more fragile than dry paper. As soon as possible, therefore, create room on the bookshelves or drawers being cleared by removing some items to ease the pressure and facilitate eventual removal. Do not try to open or close a wet book, photograph album or file of papers.
-
In cases of water damage: Remove the wettest material first, followed by less wet, and then damp. Flooded floors will soak objects stored on the floor. Burst pipes may wet items on upper shelves first. Clear wettest items first, then work from the top down to remove remaining objects from shelves.
-
In cases of water damage: Do not use staples, paper clips, felt-tip pens, ink pens, coloured paper, or adhesive tape on wet materials.

Unglazed items | Beware of repairs coming apart. Wash off as soon as possible or if muddy, allow to dry, then brush off with a soft brush. Completely wrap each object or part of an object separately, but bag all the pieces together. |
Painted unglazed items | Beware of repairs coming apart. Do not wash; dry as is, very carefully, brush off with a soft brush. Completely wrap each object or part of an object separately, but bag all the pieces together. |
Material | Procedures |
---|---|
Solid wood pieces | Blot dry. If the water has not penetrated (e.g. on polished furniture wet for only a few minutes) then it can be left to air dry without covering If the water has soaked in (e.g. if it has been lying in water for several hours) then wrap in clean cloth or paper to slow down the rate of drying which could lead to cracking and warping. If there is an oily layer, keep underwater while removing the floating oil layer with a wet vacuum before lifting the object out. If the water is just dusty or non-oily dirt then rinse off before following instructions as for clean water. |
Veneered pieces | Same as for wood If there are iron or steel fittings which will rust quickly it may be necessary to dry these out as quickly as possible to prevent staining. This will require specialist conservation advice. |
Upholstered pieces | Same as for wood May be extremely fragile and fastenings may tear through the fabric. This will require specialist conservation advice. |
Material | Procedures |
---|---|
Iron and Steel | If the flood water is reasonably clean, remove the object from the water and dry it off with a dry cloth or air dry The conservator who will make the decision as to what treatment is appropriate may specify dewatering fluids. Inappropriate treatments will damage any painted surfaces. |
Copper alloys: (brass, bronzes) | As above though unpainted copper alloys are not affected by flash rusting and can be dried by blotting with clean, lint free cloths and blotters or with fans. |
Lead and zinc | As above but special care must be taken because these metals are very dense and thus heavy yet they can be damaged because their surfaces can be easily scratched and their shapes deformed. |
Metals in general: | Do not place metal objects affected by disasters in touch with one another (different metals in contact with each other promote corrosion). Try to speed drying by using dehumidifiers in the affected rooms. |
Salvage of Fire-Damaged Collections
In some instances, areas involved in a fire may require a week or longer before they are cool enough to be entered.
Smoke damaged materials
Place items affected by smoke into the largest volume of moving air that you can find. This will dispel most lingering odours.
Conservators can remove a light film of smoke deposits with Drychem chemical sponges or soft brushing and then use the above odour reducing procedure.
Charred materials - dry
The worst charring will be noticed higher up. Little can be done for badly damaged paintings, textiles, and paper items. Charred materials should be handled gently as they are very fragile. Where possible they should be placed between cardboard sheets or in cardboard boxes and wrapped in clean, unprinted paper for protection.
It is important to be sure that charred items are totally dry before they are packed to prevent mould development. If in doubt, and if possible, allow items to air-dry in a stable environment for a week before packing. Burnt material may be housed in protective enclosures until treatment is available.
Charred materials - wet
Charred materials that are wet are exceedingly fragile. Handling must be done with extreme care. Often extra support is necessary. Sturdy cardboard, polyester film or tubs can assist in supporting materials while the collections are moved to the freezer or to dry storage. (See above, Instructions for handling water-damaged items.)
