2. COMPOSITION/INFORMATION ON INGREDIENTS
Chemical Name CAS# Wt%
Phosphorus Pentasulfide 1314-80-3
3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW/IMMEDIATE CONCERNS:
Flammable solid and dangerous when wet. Reacts with water and/or water vapor (humid air) to produce flammable and
toxic hydrogen sulfide gas and heat. Blanket spill or leaks with dry sand, clay or ground limestone. DO NOT USE WATER.
In case of fire, use dry chemical, carbon dioxide, dry sand or class D fire Extinguishers. Wear full protective clothing and
positive pressure self-contained breathing apparatus.
POTENTIAL HEALTH EFFECTS:
Airborne dust is irritating to eyes, nose, throat and skin. Reaction with moisture produces hydrogen sulfide gas that is
irritating to lungs and eyes. Exposure to high concentrations (500-1000 ppm) of hydrogen sulfide gas causes unconscious-
ness and death from respiratory paralysis.
4. FIRST AID MEASURES
EYES:
Immediately flush with water for at least 15 minutes, lifting upper and lower eyelids intermittently. See a medical doctor
immediately.
SKIN:
Remove contaminated clothing and thoroughly wash with soap and water. If irritation occurs and persists, contact a
medical doctor.

Revision No: 4
INGESTION:
Rinse mouth with water. Dilute by giving 1 or 2 glasses of water. Do not induce vomiting. Never give anything by mouth to
an unconscious person. See a medical doctor immediately.
INHALATION:
Remove to fresh air. If breathing discomfort occurs and persists, see a medical doctor. If breathing has stopped, give
artificial respirations and see a medical doctor immediately.
NOTES TO MEDICAL DOCTOR:
Hydrolyzes in the presence of moisture to hydrogen sulfide and phosphoric acid. Inhaled material in strongly irritating and
may require administration of humidified oxygen and perhaps bronchodilators. Systemic effects of hydrogen sulfide may
include alterations of consciousness, possible coma, respiratory arrest and anoxic terminal convulsions, thought to be due
to inhibition of tissue (cytochrome) respiration. Supportive care should be instituted, particularly oxygen and/or artificial
respiration (oxygen is useful here not only for hypoxia, but also to help oxidize sulfide to sulfate); there is no definitely
proven antidote, although evidence is suggestive that intentional induction of methemoglobinemia - as for cyanide poisoning
may be helpful. For this purpose, amyl nitrite may be given by inhalation until an intravenous preparation of sodium nitrite
can be given slowly in an average starting dose of about 10cc of 3% solution for an adult. Careful attention to acid-base
balance and its adjustment is also important.
5. FIRE FIGHTING MEASURES
FLAMMABLE LIMITS:
Not applicable
AUTOIGNITION TEMPERATURE:
Dust 260-290 degrees C
EXTINGUISHING MEDIA:
C02, dry chemical, sand and sodium chloride base D extinguishers - NFRS recommendation.
EXPLOSION HAZARDS:
Ignitable by spark or friction; dust presents explosion hazard; combustion yields toxic and corrosive phosphorus pentoxide
and sulfur dioxide. Reacts with water to liberate toxic and flammable hydrogen sulfide gas and phosphoric acid.
FIRE FIGHTING PROCEDURES:
Do not use water. Entire bulk of material must be covered by extinguishing agent to prevent reignition. Goggles, protective
clothing, and positive pressure self-contained breathing apparatus should be worn to protect against toxic gas and corrosive
fumes.

FIRE EXPLOSION:
Not known to be explosive.
SENSITIVITY TO STATIC DISCHARGE:
None
SENSITIVITY TO IMPACT:
None
HAZARDOUS DECOMPOSITION PRODUCTS:
Sulfur dioxide and phosphorus pentoxide from oxidation and hydrogen sulfide and phosphoric acid from reaction with water.
Water, acids and oxidizing materials.
6. ACCIDENTAL RELEASE MEASURES
RELEASE NOTES:
Wear full personal protective equipment as perscribed in Section 8. Keep spill covered to prevent exposure to moisture,
using grounded tools, transfer into clean, dry containers. Avoid creating dust. Coat spill area with dry soda ash or sand.
Carefully transfer into container. Finally flush residue in spill area with very large quantities of water.
7. HANDLING AND STORAGE
HANDLING:
Use in a totally enclosed process with a low moisture inert atmosphere. Maintain a low humidity atmosphere in the work
areas where containers are opened and product is transferred to process. Avoid sliding or rough handling of containers. Dry
powders can build static electricity when subjected to the friction of conveying, mixing or sliding. Adequate precautions,
such as electrical grounding, bonding and inert atmospheres should be taken when P2S5 is either loaded or unloaded in
order to prevent potential ignition. Grounding is not required during transportation.
STORAGE:
Store in cool, dry, well ventilated areas (mechanical exhaust ventilation system, if necessary) away from combustibles or
open flames. Thoroughly ventilate vans or box cars to remove hydrogen sulfide gas. Grounding is not required during
storage.
COMMENTS:
VENTILATION: Local exhaust ventilation must be provided for all potential sources of release of airborne product dust
and toxic flammable hydrogen sulfide gas (lower explosive limit is 4.3%; upper explosive limit is 46.0%). The exhaust
system should be designed with proper duct and capture velocities consistent with controlling release below established
exposure limits. Use airline supplied respirator or self contained breathing apparatus if ventilation system is not adequate.
