I don't recall seeing anything about this restriction from the EPA. The Uniform Fire Code places a restriction of 60-gallons for containers and 660-gallons for portable tanks. Also, the Uniform Fire Code states that indoor storage of flammable and combustible liquids must not exceed the exempt amounts set forth in their table 7902.5-A. Table 7902.5-A lists the maximum quantities of flammable and combustible liquids that can be stored per control area. The requirements are as follows: Flammable Liquids: Class I-A 30 gallons (FP < 73F and BP < 100F) Class I-B 60 gallons (FP < 73F and BP > 100F) Class I-C 90 gallons (FP between 73F - 100F)[no mention of BP] Combination of I-A, I-B, I-C 120 gallons (combinations may not contain more than the exempt amounts of any individual class) Combustible Liquids: Class II 120 gallons (FP between 100F - 140F) Class III-A 330 gallons (FP between 140F - 200F) Class III-B 13,200 gallons (FP >200F)[no limit if building has an approved automatic sprinkler system) The Uniform Fire Code states that control areas must be separated from each other by not less that a one-hour fire-resistive occupancy separation. For printers, the number of control areas must not exceed four. Flammable & combustive liquid quantities are allowed to be increased 100% when stored in approved storage cabinets. Quantities are also allowed to be increased 100% in buildings equipped with an approved automatic sprinkler system. Therefore, if an approved storage cabinet is used in a building with an approved automatic sprinkler system, the volumes permitted to be stored in each control area can be three times the volume in the table above. According to federal OSHA 1910.106 (d)(2)(iii), individual containers of flammable or combustible liquids must not exceed the volumes in table H-12 as follows: Class IA Class IB Class IC Class II Class III Glass or approved plastic 1 pt. 1 qt. 1 gal. 1 gal. 1 gal. Metal (other than DOT drums) 1 gal. 5 gal. 5 gal. 5 gal. 5 gal. Safety cans 2 gal. 5 gal. 5 gal. 5 gal. 5 gal. Metal drums (DOT specifications) 60 gal. 60 gal. 60 gal. 60 gal. 60 gal. The only thing else I can think of that may cause an employer to restrict the use of solvents at the press might be the Methylene chloride rule. Restricting the use of Methylene chloride at the press might help to keep the airborne concentrations below the TLV.
