Guide Information for Fire Protection Equipment

This category covers record protection equipment, insulated vault doors and file room doors intended to provide protection to paper records (Class 350) against loss by fire of controlled extent and severity for periods designated by the hourly ratings indicated in the individual Classifications.

Record protection equipment (Classes 150 and 125) is also intended to provide protection to records other than paper against loss by fire of controlled extent and severity for periods designated by the hourly ratings indicated in the individual Classifications. Class 150-rated devices afford protection to magnetic tapes and other types of magnetic data processing media, photographic film and records other than paper. Class 125-rated devices afford protection to certain types of flexible disks.

Record protection equipment investigated for impact resistance (as indicated in the individual Classifications) is intended to provide protection to records in buildings when collapse may or may not be expected to occur as a result of fire since the rating includes investigation of impact stability.

Record protection equipment not investigated for impact resistance is not intended to provide protection in buildings when collapse may be expected to occur as a result of fire since the rating does not include an investigation of impact stability. Record protection equipment not investigated for impact resistance which is rated Class 350 provides less protection to records than does record protection equipment investigated for impact resistance rated Class 350 as evidenced by the location at which interior temperatures are measured during the fire tests.

Insulated vault doors and file room doors (Class 350) are intended to provide protection to records when installed in accordance with the manufacturer's instructions in vaults or file rooms constructed as specified in ANSI/NFPA 232, "Standard for the Protection of Records."

The fire-resistance rating indicated in the individual Classifications may be seriously impaired by disturbance or injury of the insulation material due to fire, burglary or improper application of accessories. Repairs to insulation or steel components should be made at the manufacturer's factory.

Authorities Having Jurisdiction should be consulted as to which fire-resistance rating of record protection devices will be suitable for the situation where it is to be used.
