Sec. 1500.15  Labeling of fire extinguishers.

    When a substance or mixture of substances labeled for use in or as a 
fire extinguisher produces substances that are toxic within the meaning 
of Sec. 1500.3(c) (1) and (2) when used according to label directions 
to extinguish a fire, the containers for such substances shall bear the 
following labeling:
    (a) When substances are produced that meet the definition of highly 
toxic in Sec. 1500.3(c)(1), the signal word ``Danger'' and the 
statement of hazard ``Poisonous gases formed when used to extinguish 
flame or on contact with heat'' are required labeling.
    (b) When substances are produced that meet the definition of toxic 
in Sec. 1500.3(c)(2), the signal word ``Caution'' or ``Warning'' and 
the statement of hazard ``Dangerous gas formed when used to extinguish 
flame or on contact with heat'' are required labeling.
    (c) Regardless of whether paragraph (a) or (b) of this section 
applies, any substance or mixture of substances labeled for use as a 
fire extinguisher that, if applied to an electrical fire, would subject 
the user to the likelihood of electrical shock shall be conspicuously 
labeled ``Caution: Do not use on electrical wires.''
    (d) The statements specified in paragraphs (a), (b), and (c) of this 
section shall be in addition to any other that may be required under the 
act. All such substances or mixtures of substances shall also bear the 
additional statements ``Use in an enclosed place may be fatal'' and ``Do 
not enter area until well ventilated and all odor of chemical has 
disappeared.''
