What QA looks for
QA should inspect flammable storage lockers for the following:

1. Cabinet construction and labeling — Metal cabinet or wall locker with stenciling reading "FLAMMABLE—KEEP FIRE AWAY" [DAFMAN 91-203 para 22.7.7.2].

2. Liquid quantity compliance — Contents limited to 1 gallon (4 liters) of Class I liquids OR 10 gallons (40 liters) of Class II/III liquids, not exceeding 10 gallons (40 liters) total per cabinet; five-day supply maximum [DAFMAN 91-203 para 22.7.7.3].

3. Container condition — All liquids stored in closed containers [DAFMAN 91-203 para 22.7.7.3]; containers are only opened when in use [DESR 6055.09 DAFMAN 91-201 V1.E10.6.13.4].

4. Incompatible materials separation — No fuel sources (wood, paper, rags) stored with flammable materials [DESR 6055.09 DAFMAN 91-201 V1.E10.6.13.3]; waste rags impregnated with flammable materials in approved self-closing metal waste containers, disposed of daily or end of shift [DAFMAN 91-203 para 30.3.2].

5. Location and isolation — Locker positioned at least 50 feet from explosives locations or isolated by approved fire walls [DESR 6055.09 DAFMAN 91-201 V1.E10.6.13.6]; designed IAW NFPA 30 [SSCMAN 91-710V6 para 10.6.1].

6. Inspection frequency — Monthly inspection record maintained [

verse environmental impacts in the event of an accidental explosion. V4.E5.13.6. (Added)(DAF) Separate these materials as required by NFPA 30, or by 50 feet, whichever is greater. (T-0) An example of this facility type would be small lockers used to store operational quantities of POL and other flammable materials in support of a single PES or ES. This criteria does not apply to small daily use storage lockers located in operating environments. V4.E5.13.7. For underground AE facilities, it is not practical to specify QD criteria that cover all tank storage configurations. The DoD Component must assess each configuration in accordance with Volume 5 – Enclosure 5 of this manual to ensure that protection equivalent to paragraphs V4.E5.13.1. through V4.E5.13.6. is provided.
