HEALTH & SAFETY INFORMATION
•
Poisonous. Chlorates produce methemoglobin in the blood, destroying red blood
cells. May cause kidney irritation and heart muscle damage. Chronic exposure
may cause blood changes; kidney, liver, and heart damage.
Respirator:
At
any concentrations above the NIOSH REL, or where there is no REL, at any
detectable concentration:
SCBAF:PD,PP
(any self-contained breathing apparatus that has a full facepiece and is
operated in a pressure-demand or other positivepressure mode) SAF:PD,PP:ASCBA
(any suppliedair respirator that has a full facepiece and is operated in a
pressure-demand or other positive-pressure mode in combination with an
auxiliary self-contained breathing apparatus operated in a pressure-demand or
other positive-pressure mode).
Escape:
GMFOV
[any airpurifying, full-facepiece respirator (gas mask) with a chin-style,
front-or back-,mounted organic vapor canister] SCBAE (any appropriate
escape-type, selfcontained breathing apparatus).
Reactivity:
A
powerful oxidizer; reacts violently with reducing agents and combustible
substances. Explosions may result from contact with ammonia salts, carbon,
oils, metal sulfides, nitrobenzene, powdered metals, sugar. Contact with strong
acids gives off carbon dioxide. Forms shock-sensitive mixture with some organic
materials. Solution (50%) decomposes at 300°F (149°C) liberating oxygen and
increasing fire risk. Do not use combustible absorbents on spills.
FIRE INFORMATION
Noncombustible
solid, but may increase intensity of fire. Chlorates are powerful oxidizers.
Contact with combustible may cause contamination that make them sensitive to
shock, friction, and elevated temperatures. When heated to decomposition,
chlorates emit toxic fumes of chlorine and may explode. Forms explosive
mixtures with aluminum powder and other powdered metals.

FIRST AID:
Move
victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Administer oxygen if breathing is difficult. Remove
and isolate contaminated clothing and shoes. In case of contact with substance,
immediately flush skin or eyes with running water for at least 20 minutes. Keep
victim warm and quiet. Ensure that medical personnel are aware of the
material(s) involved, and take precautions to protect themselves.
