CSLB C-33 Painting & DecoratingSafetyHard
A painting contractor is instructing new hires on the proper storage of flammable paints and thinners. According to OSHA, what is the maximum aggregate quantity of Class I, Class II, and Class IIIA liquids that may be stored in a storage cabinet without exceeding regulatory limits?
- A60 gallons
- B30 gallons
- C90 gallons
- D120 gallons
Show answer & explanationAnswer & explanation
Correct answer: A. 60 gallons
OSHA 1910.106(d)(3)(ii) specifies that not more than 60 gallons of Class I and Class II liquids, nor more than 120 gallons of Class III liquids, may be stored in a single storage cabinet. Therefore, the aggregate for Class I, Class II, and Class IIIA (which are Class III liquids) in a single cabinet cannot exceed 60 gallons if Class I or II are present.
Why the other options are wrong
- B. Too low; while some codes might restrict smaller quantities in certain situations, 60 gallons is the general OSHA limit for Class I/II.
- C. This quantity is typically for Class III liquids only, not an aggregate including Class I/II.
- D. This quantity is typically for Class III liquids only, exceeding the limit if Class I/II are included.
Flammable Liquid Cabinet Limits
The maximum volume of flammable and combustible liquids permitted to be stored in an approved flammable liquid storage cabinet, as specified by OSHA.
- Class I and II liquids have stricter limits than Class III.
- A single cabinet has a specific aggregate limit.
- Proper storage prevents large-scale fires.
Memory trick: Sixty gallons of fire, no more can inspire.
