Training is an important part of a disaster preparedness plan, to ensure that staff are familiar with the contents of the plan and understand how to effectively carry out the established protocols. A variety of templates and guides have been published to assist cultural organisations prepare for disasters:
Water is one of the agents of deterioration. Its effects can be seen in these flood-damaged library books. The 'ten agents of deterioration' are a conceptual framework developed by the Canadian Conservation Institute (CCI) used to categorise the major causes of change, loss or damage to cultural heritage objects (such as collections held by galleries, libraries, archives and museums).

Water causes damage and results from natural occurrences, technological hazards, or mechanical failures. Many cases of water damage can be traced to accidents or neglect. "A great many of the materials that museum objects are made of are highly susceptible to contact with water and can be severely damaged by even brief contact, while others may be exposed to water for longer periods without harm.
Any foreign object flying in the intake flew in, hit the door, opened it, flew through, and then exited the aircraft. Thus, only small objects swept up by the air could enter the engine. This design did indeed prevent FOD problems, but the constriction and drag induced by the bending of the airflow reduced the engine's effective power, and thus ...
Spill containment is where spills of chemicals, oils, sewage etc. are contained within a barrier or drainage system rather than being absorbed at the surface. One method is to use an inflatable stopper or pneumatic bladder which is inserted into the outflow of a drainage system to create a containment vessel.
Objects may be coated with fire retardants. For example, Christmas trees are sprayed with retardants, as a tree dries out it becomes very flammable and a fire-hazard. Steel structures have a fire retardant coating around columns and beams to prevent structural elements from weakening during a fire.
Conservation and restoration of ceramic objects is a process dedicated to the preservation and protection of objects of historical and personal value made from ceramic. Typically, this activity of conservation-restoration is undertaken by a conservator-restorer , especially when dealing with an object of cultural heritage .
Airborne leaflets have been used for military propaganda purposes at least since the 19th century. One early example is from the Franco-Prussian War when, in October 1870 during the Siege of Paris, a French balloon coming from the city dropped government proclamations over North German Confederation troops that stated the following (in German):
