protected for dispensing Class I flammable
liquids that meet the requirements of NFPA 30.
22.214.171.124 Transfer of Class I liquids from containers of 19L
NFPA 45, 126.96.36.199
(5 gal.) or more capacity shall be carried out as
· In a separate building; OR
· In a liquid storage area specifically designed for
dispensing Class I flammable liquids that meet
the requirements of NFPA 30.
188.8.131.52 Class I liquids shall not be transferred between
NFPA 45, 184.108.40.206
conductive containers of greater than 4L (1.1 gal.)
capacity unless the containers are electrically
interconnected by direct bonding or indirect
bonding through a common grounding system.
When dispensing Class I liquids involves
nonconductive containers larger than 4L (1.1gal.),
which can be difficult to bond or ground, special
dispensing procedures commensurate with the
electrical characteristics of the liquid shall be
developed and implemented.
220.127.116.11 Individual containers of flammable or combustible
NFPA 45, 18.104.22.168
liquids shall not exceed the capacities listed in
NFPA 45, Table 22.214.171.124.
126.96.36.199 The quantity of flammable solids, solid or liquid
NFPA 45, 7.3-5
oxidizers, or peroxides allowed shall be limited to
the minimum quantity necessary to perform the
work being done. Handling of materials shall
conform to the manufacturers' recommendations.
Laboratory Compressed Gases In addition to the
NFPA 45, 8.1.4-6
requirements in Section 4.3, above, compressed gas
cylinders in laboratories must also meet the
requirements in sections 188.8.131.52-5 below.
184.108.40.206 Lecture bottle-sized cylinders of the following
NFPA 45, 220.127.116.11
gases located in laboratory units shall be kept in a
continuously mechanically ventilated hood or other
continuously mechanically ventilated enclosure:
(1) All gases that have an NFPA 45 Health Hazard
Ratings of 3 or 4;
(2) All gases that have a NFPA 45 Health Hazard
Rating of 2 without physiological warning
(3) Pyrophoric gases
