1. Laboratory design shall include spill control and secondary containment for the storage of hazardous materials liquids in accordance with the requirements of Uniform Fire Code Sections 8003.1.3.
CCR, Title 8, Section 5164
Notes:
(a) Design must allow for substances which, when mixed, react violently, or evolve toxic vapors or gasses, or which in combination become hazardous by reason of toxicity, oxidizing power, flammability, explosibility, or other properties, to be separated from each other in storage by distance, by partition, or otherwise, so as to preclude accidental contact between them.
(b) Explosion control shall be provided as required by Uniform Fire Code Section 8003.1.7 for storage of non-exempt quantities of the following materials:
- Highly toxic flammable or toxic flammable gases when not stored in gas cabinets, exhausted enclosures or gas rooms.
- Combusible dusts.
- Class 4 oxidizers.
- Unclassified detonable and Class 1 organic peroxides.
- Pyrophoric gases.
- Class 3 and 4 unstable (reactive) materials.
- Class 2 and 3 water-reactive solids and liquids.
2. When the hazardous materials stored in a control area are not in excess of the amounts specified in the tables below, such storage shall conform to the Building Code requirements for Group B Occupancy. (Please refer to Table 3-D, Table 3-E))
CCR, Title 24, Part 2, Section 304
CCR, Title 24, Part 2, Section 307
CCR, Title 24, Part 2, Table 3-D, 3-E
CCR, Title 24, Part 9, Table 8001.13-B
3. When the hazardous materials stored in a control area exceed the amounts specified in Table 3-E below, such storage shall conform to the Building Code requirements for Group H, Division 7 (“H-7”) Occupancy.
CCR, Title 24, Part 2, Section 307
CCR, Title 24, Part 2, Table 3-E
4. When the hazardous materials stored in laboratories and similar areas used for scientific experimentation or research are not in excess of the tables below and are not otherwise classified as Group B Occupancies, shall conform to the Building Code requirements for Group H, Division 8 (“H-8”) Occupancy. (Please refer to Table, H-8 Occupancy Storage Exempt Amounts for Lab Suites).
CCR, Title 24, Part 2, Section 307
CCR, Title 24, Part 2, Table 3-D.1, 3-i
(Notes: A laboratory suite is a space up to 10,000 square feet (929 square meters), bounded by not less than a one-hour fire-resistive occupancy separation within which the exempt amounts of hazardous materials may be stored, dispensed, handled or used. Up through the third floor and down through the first basement floor, the quantity in this table shall apply. Fourth, fifth and sixth floors and the second and third basement floor level quantity shall be reduced to 75 percent of this table. The seventh through the 10th floor and below the third basement floor level quantity shall be reduced to 50 percent of this table.)
