Applies to the handling, storage and use of flammable liquids with a flashpoint at or below 199.4 F (93 C), divided into Category 1 (flashpoint below 73.4 F and boiling point at or below 95 F), Category 2 (flashpoint below 73.4 F, boiling point above 95 F), Category 3 (flashpoint 73.4 F to 140 F) and Category 4 (above 140 F to 199.4 F); liquids heated for use to within 30 F of their flashpoint are handled under the rules for the next more hazardous group (for example a heated Category 4 liquid as a Category 3 liquid with flashpoint at or above 100 F). Excluded (j): bulk transportation, fuel oil tanks connected to oil burning equipment, farm storage, liquids without flashpoints, mists and sprays other than flammable aerosols, and installations built to NFPA 32, 35, 36 or 37. Tank storage (b): tanks of steel or engineered materials built to UL, API or ASME standards; atmospheric tanks not used at or above boiling point; shell-to-shell spacing at least 3 feet and one-sixth the sum of diameters (half the sum for unstable liquids); LP-gas containers at least 20 feet from flammable liquid tanks; normal venting at least 1 1/4 inch and emergency relief venting per Table H-10; vents for Category 1 normally closed, vent outlets at least 12 feet above grade and 5 feet from openings; drainage to an impounding area or dikes holding the largest tank; underground tanks with 2 feet of cover (or 1 foot plus 4-inch slab), corrosion protection and vents at least 12 feet up; tanks inside buildings only as permitted, with heat-actuated valves and overflow prevention; 2-hour fire-resistant supports; flood and earthquake precautions; ignition source control; strength and tightness tests before service (underground at 3 to 5 psi). Piping (c): steel, nodular or malleable iron (exceptions allowed), liquid-tight joints, supports, corrosion protection, valves and check valves, hydrostatic test at 150 percent (or pneumatic at 110 percent, at least 5 psig) held at least 10 minutes. Containers and portable tanks (d), up to 60 gallons and 660 gallons: approved containers sized per Table H-12 (for example Category 1 glass 1 pint, safety cans 2 gallons); storage cabinets holding no more than 60 gallons of Category 1 to 3 or 120 gallons of Category 4, limiting interior temperature to 325 F in a 10-minute fire test and labeled "Flammable, Keep Fire Away"; inside storage rooms per Table H-13 with 4-inch sills, six air changes per hour, Class I Division 2 wiring where required and a 3-foot aisle; no storage blocking egress; office storage only as needed in cabinets or safety cans; outside storage limits (1,100 gallons adjacent to buildings, else 10 feet); a 12-B extinguisher within 10 feet of storage room doors and 10 to 25 feet from other indoor storage; no smoking or open flames. Industrial plants (e): outside cabinets or rooms, no more than 25 gallons of Category 1 in containers, 120 gallons of Category 2 to 4 in containers or 660 gallons in one portable tank per fire area; covered containers, closed transfer (no air pressure transfer), bonding of nozzle and container, ventilation of 1 cubic foot per minute per square foot, Class I Division 1 and 2 zones, supervised hot work, and daily disposal of waste. Bulk plants (f), service stations (g) (emergency power cutoff, listed dispensers, 6 B,C extinguisher within 75 feet of each pump, no smoking, engines off), processing plants (h) and refineries, chemical plants and distilleries (i) carry further siting, loading-rack bonding, electrical classification (Tables H-18, H-19) and fire control duties, including 25-foot (or 15-foot) separation of loading facilities.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
