Document Class Number 6050, issued by FM Approvals, lists the standards expected for storage cabinets of flammable and combustible liquids, like gasoline. Requirements begin with design, cover manufacture and testing and include quality assurance procedures.
Number 6050, Approval Standard for Storage Cabinets (Flammable and Combustible Liquids) provides the requirements as defined by FM Approvals, a member of the FM Global Group. The FM Approvals diamond shaped certification mark verifies that the product meets safety, quality and performance criteria.
General Requirements
The cabinet cannot exceed 120 gallons and needs to be made from double wall steel or single wall wood construction. Its doors must be lockable and non-sparking. All cabinets need to be labeled with the words Flammables - Keep Fire Away, among other information,
Performance Requirements
The cabinet’s maximum storage capacity needs to be tested, as well as the results of 10 minute fire exposure. Flame arresters and self-closing doors are required to meet the standards. Door mechanisms are tested for ability to hold the door open. Spill containment requires a leak-tight sump or pan.
Operations Requirements
The standards are concerned with the quality assurance program for design, testing, inspection, equipment, drawing and change control, packaging, shipping, and disposal of incompatible materials.
Careful documentation and record-keeping are required to ensure policies that prevent unauthorized changes. A record needs to be kept of all revisions. All changes must be channeled through the appropriate group for FM Approval. The manufacturing plant is also audited at least once a year.
