IV FIRE AND EXPLOSION HAZARDS DATA
Flash Point (Method used): N/E Autoignition Temperature: No Data
Extinguishing Media: DO NOT USE WATER. Use dry chemical extinguishing agents, dry sand, dry ground dolomite, carbon
dioxide.
Special Fire Fighting: Wear NIOSH/MSHA approved self-contained breathing apparatus, flame and chemical resistant protective
clothing, hat, gloves and boots. If without risk move material out of fire area.
Unusual Fire & Explosion: Fire hazard when exposed to flame or by spontaneous chemical reaction. Reacts with water, steam or
acids to produce toxic and flammable vapors of hydrogen sulfide.
V HEALTH HAZARD INFORMATION
Effects of Overexposure: Toxic by ingestion via the liberation of hydrogen sulfide, symptoms include vomiting, gastric pain and
dizziness. Can cause skin and eye irritation. Inhalation can cause irritation to the respiratory tract.
EMERGENCY AND FIRST AID PROCEDURES: Remove from exposure.
EYES: Immediately flush with copious amounts of water for 15 minutes then seek prompt, competent medical attention.
SKIN: Brush material off exposed area, remove any contaminated clothing, flush area with running water for 15 minutes. If skin is
burned seed prompt, competent medical attention.
INHALATION/INGESTION: Seek prompt, competent medical attention immediately.
VI REACTIVITY DATA
Stability: Stable
Conditions to Avoid: Heating to decomposition emits toxic fumes of SOx. Avoid contact with water, steam or acids which will
cause the production of toxic and flammable vapors of hydrogen sulfide.
Incompatibility (Material to Avoid): Cadmium chlorate, chlorates, chloric acid, hydrogen peroxide, magnesium, ammonium nitrate,
potassium chlorate and water, zinc chlorate, powerful oxidizers.
Hazardous Decomposition Products: Hydrogen sulfide, copper I sulfate
Hazardous Polymerization: Will not occur.
Conditions to Avoid: N/A
VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wearing respiratory protection and protective clothing (see Section
VIII), eliminate all sources of ignition, cover spill with vermiculite or sodium bicarbonate, collect into a plastic bag or wide mouthed
glass container, close tightly and submit or retain for disposal.
Waste Disposal Method: In accordance with Local, State and Federal Regulations for proper disposal of inorganic sulfides.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): NIOSH/MSHA approved high efficiency particulate respirator for ordinary use, self-
contained breathing apparatus for emergency use.
Ventilation: Local Exhaust: Fumehood Mechanical: Not adequate
Special: Glove bag or box with dry inert atmosphere.
Protective Gloves: Rubber Eye Protection: Chemical safety goggles
Other Protective Equipment: Laboratory coat and apron, eye wash fountain capable of sustained flushing, safety drench shower,
hygienic facilities for washing.
IX SPECIAL PRECAUTIONS
Precautionary Labeling: DANGER! TOXIC! Do not ingest. WARNING! IRRITANT! Do not inhale. Avoid contact with skin,
eyes and clothing. FLAMMABLE! Keep away from heat, sparks and open flame.
Other Handling and Storage Conditions: Store in cool dry place away from sources of moisture and powerful oxidizers. Wash
thoroughly after handling. Keep container tightly closed. Use adequate ventilation.
