Guidance on Safe Use
Administrative data
First-aid measures
Description of first aid measures
Skin
Wash with soap and water. Get medical attention if irritation develops. Launder contaminated clothing before reuse.
Eyes
Flush with water at least 30 minutes. Get medical attention if eye irritation develops or persists.
Inhaled
Remove victim to fresh air and keep at rest in a position comfortable for breathing. If breathing is labored, administer oxygen. If breathing has stopped, apply artificial respiration. CONTINUE UNTIL VICTIM RESUMES BREATHING. Call a poison center or doctor if exposed or you feel unwell.
Swallowed
DO NOT INDUCE VOMITING. Get immediate medical attention.
Advice for first-aid providers
When providing first aid always protect yourself against exposure to chemicals or blood borne diseases by wearing gloves, masks and eye protection. If providing CPR use mouthpieces, resuscitation bags, pocket masks or other ventilation devices. After providing first aid wash your exposed skin with soap and water.
Most important symptoms and effects, both acute and delayed
See section “Toxicological Information”.
Indication of any immediate medical attention and special treatment needed
Note to physician: Hydrosulfide anion is strongly bound to hemoglobin in a manner similar to cyanide. A dose of sodium nitrite would produce methemoglobin in the blood which would then partially inactivate this poison. If exposed or concerned: Get medical attention.
Fire-fighting measures
Fire Fighting Measures
Extinguishing Media
CO2, dry chemical, or foam. Water can be used to cool and protect exposed material.
Special hazards arising from substance or mixture
Toxic fumes, gases or vapors may evolve on burning or exposure to heat. Material may contain hydrogen sulfide. Hydrogen sulfide is a toxic and flammable gas.
See section “Stability and Reactivity” for additional information.
Advice for firefighters
Wear full protective fire gear including self-containing breathing apparatus operated in the positive pressure mode with full face piece, coat, pants, gloves and boots. Water may cause splattering.
Accidental release measures
Accidental Release Measures
Personal precautions, protective equipment and emergency procedures
Keep unnecessary personnel away. Personal protective equipment must be worn. Ventilate area if spilled in a confined space or other poorly ventilated area.
Eliminate all ignition sources if safe to do so.
Environmental precautions
Take precautions to avoid release to the environment. Prevent from entering into soil, ditches, sewers, waterways and/or groundwater.
Methods and material for containment and cleaning up
Pick up free liquid for recycle and/or disposal. Residual liquid can be absorbed on inert material.
Reference to other sections
See sections “Exposure Controls/Personal Protection” and “Disposal Considerations” for additional information.
Handling and storage
Handling and Storage
Precautions for safe handling
Keep away from potential sources of ignition. Liberates hydrogen sulfide gas. Open container carefully and only in adequately ventilated areas or use appropriate respiratory protection. Keep containers closed when not in use. Do not discharge into drains or the environment, dispose to an authorized waste collection point.
Use appropriate containment to avoid environmental contamination. When handling, do not eat, drink, or smoke. Do not breath dust, fume, gas, mist, vapors or spray. Use only outdoors or in a well-ventilated area. Avoid skin contact. Wash thoroughly after handling. Launder contaminated clothing before reuse. Empty container contains product residue which may exhibit hazards of product. Dispose of packaging or containers in accordance with local, regional, national and international regulations.
Pumping Temperature
Not determined.
Maximum Handling Temperature
Not determined.
Maximum Loading Temperature
Not determined.
Conditions for safe storage, including any incompatibilities
Do not store near potential sources of ignition. Store in well ventilated place. Take precautions to avoid release to the environment. See section 10 for incompatible materials.
Maximum Storage Temperature
Not determined.
Specific end use(s)
End uses are listed in an attached exposure scenario when one is required.

Other Exposure Limits
Material may liberate hydrogen sulfide gas. The ACGIH TLV-TWA for hydrogen sulfide is 1 ppm, the ACGIH 15 minute STEL is 5 ppm. The OSHA acceptable ceiling concentration for hydrogen sulfide is 20 ppm. A 10 minute maximum peak of 50 ppm is permitted once, only if no other measurable exposure occurs. The National Institute of Occupational Safety and Health immediately dangerous to life or health (IDLH) value is 100 ppm.
Exposure controls
Use local exhaust ventilation to control mists or vapors. Additional ventilation or exhaust may be required to maintain air concentrations below recommended exposure limits.
Eye/face protection
Safety Glasses.
Skin protection
Use nitrile or neoprene gloves.
Long sleeve shirt is recommended. Launder contaminated clothing before reuse.
Respiratory Protection
Use respirator with a combination organic vapor and high efficiency filter cartridge if recommended exposure limit is exceeded. Use self-contained breathing apparatus for entry into confined space, for other poorly ventilated areas and for large spill clean-up sites. Hydrogen sulfide causes olfactory fatigue and thus has poor warning properties. The use of a full faced supplied air respirator is recommended if exposure limits are exceeded. Consult with an industrial hygienist to determine the appropriate respiratory protection for your specific use of this material. A respiratory protection program compliant with all applicable regulations must be followed whenever workplace conditions require the use of a respirator.
