Substandard

Money can be saved fraudulently by using apparently suitable fireproofing that is not built to the required standard. Such fraud can be prevented when documentation is required and checked to ensure that all installed configurations meet the certification standards.

Work staging

Spray fireproofing products have not been qualified to the thousands of firestop configurations, so they cannot be installed in conformance of a certification listing. Therefore, firestopping must precede fireproofing. Both need one another. If the structural steel is left without fireproofing, it can damage fire barriers and a building can collapse. If the barriers are not firestopped properly, fire and smoke can spread from one compartment to another.

Fireproof vaults

Fireproof vaults to protect important paper documents are usually built using concrete or masonry blocks as the primary building material. In the event of a fire, the chemically-bound water within the concrete or masonry blocks is forced into the vault chamber as steam, which soaks the paper documents to keep them from igniting. This steam also helps keep the temperature inside the vault chamber below the critical threshold, which is the point at which information on paper documents is destroyed. The paper can later be remediated with a freeze drying process if the fire is extinguished before internal temperatures exceed . An alternate less expensive and time-consuming construction method is using dry insulating material. This vault construction method is sufficient for paper documents, but the steam generated by concrete and masonry structures will destroy contents that are more sensitive to heat and moisture. For example, information on

All components of fireproof vaults must meet the fire protection rating of the vault itself, including doors, HVAC penetrations and cable penetrations.National Fire Protection Association 232 "Protection of Records"
