Be able to deal with this kind of emergency quickly. Never ever store collections on the floor for any period of time. Assess your fire protection equipment and methods. This is a critical issue. Fire protection methods change all the time.
Some systems are very old.
Also, the staff tend not to know what to do if the equipment needs to be activated. For example, a Halon discharge is so powerful, it can destroy documents stored adjacent to the Halon nozzle. Re-evaluate your systems continually. Ban smoking in the collections area. Also, check where the smoking area is in relation to your precious materials.
