Overall Design Process

Laboratories that store, use, or handle more than 10 gallons of flammable or combustible liquids shall have one or more flammable liquid storage cabinets. 

 

24 CCR 9 (CFC), 7903.2.1.6

 

Flammable liquid storage cabinets shall not store in excess of 60 gallons of Class I flammable or Class II combustible liquids. 

 

24 CCR 9 (CFC), 7902.5.9.2

NFPA 30, Chapter 4-3.1

 

Flammable liquid storage cabinets shall be conspicuously labeled with the warning "FLAMMABLE — KEEP FIRE AWAY" in red letters on a contrasting background. Doors shall be well fitted, self closing and equipped with a self-latching device. 

 

8 CCR 5533

NFPA 30, Chapter 4-3.5

24 CCR 9 (CFC), 8001.10.6.2

 

When flammable or combustible liquids present multiple hazards, the storage requirements for each hazard shall be addressed.

 

For example, acetic acid is a corrosive and combustible material. Therefore, if It is stored in a flammable cabinet with other flammable materials, it shall be segregated (i.e., secondary containment).

 

24 CCR, 7902.5 et seq

 

Laboratories that store, use, or handle more than 10 pounds of highly toxic liquids or solids shall have one or more approved and vented toxic material storage cabinet. 

 

24 CCR 9 (CFC), Sections 8003.1, 8003.3.1.3.2, 8003.3.1.3.1 8003.3.1.3.5, 8003.12, et seq, 8001.15.2.3.1 (note exception), and 8001.10.6.2; Table 8001.15-A-D, 8001.10.6

24 CCR 2 (CBC) Chapter 3, Tables 3-E and 3-I

 

Where necessary, vented cabinets should be provided to store toxic materials, separated by hazard class. The vents shall be connected, preferably at the top of the cabinet to a supply ventilation system and the bottom of the cabinet to an exhaust ventilation system in accordance with the provisions of the 'Venting Hazardous Material Storage Cabinets' section of this chapter. Interior balance of the cabinet should be neutral to the outside. The cabinets should be compatible with the materials being stored. 

 

UC Practice

Prudent Practices in the Laboratory, Section 3.C and 5.D

 

Corrosive/toxic material storage cabinet shelving shall be constructed to prevent spillage of contents with tight-fitting joints, a welded or riveted liquid-tight bottom, a door sill of at least 2 inches, and lockable cabinet doors that are self-closing and self-latching. Corrosive materials should not be stored in metal cabinets unless the materials of construction are specifically treated to be corrosion-resistant.
