Section 3: HAZARDS IDENTIFICATION
NFPA: Health - 3 Flammability - 1 Reactivity - 1
Warning: Avoid inhalation of product fumes near openings on storage container.
Upon release of product solution to the environment ammonia and
hydrogen sulfide vapors will evolve. Both of these gases are highly toxic.
Product solution is alkaline and corrosive to the skin.
Eye contact will cause severe eye irritation and possible corneal damage.
Ingestion will result in corrosion of tissues of the gastrointestinal tract.
Section 3: HAZARDS IDENTIFICATION, Cont.
3.1 POTENTIAL HEALTH EFFECTS
EYE: Contact with the eyes by product mist or solution will cause irritation and a burning sensation. Eye
contact may result in severe corneal injury.
SKIN CONTACT: Contact with product mist or solution will cause skin irritation and may result in corrosion of
SKIN ABSORPTION: Absorption is unlikely to occur.
INGESTION: Ingestion of product solution will cause irritation and corrosion of the gastrointestinal tract to
include nausea, vomiting and diarrhea. Contact with stomach acid will cause highly toxic hydrogen sulfide to
INHALATION: Inhalation of product vapors (ammonia and hydrogen sulfide) will cause dizziness and
unconsciousness possibly resulting in serious falls from elevated positions..
CHRONIC EFFECTS/CARCINOGENICITY: Not listed as a carcinogen by NTP, IARC or OSHA.
Section 4: FIRST AID MEASURES
4.1 EYES: Immediately flush with large quantities of water for 15 minutes. Hold eyelids apart during irrigation
to insure thorough flushing of the entire area of the eye and lids. Obtain immediate medical attention.
4.2 SKIN: Immediately flush with large quantities of water. Remove contaminated clothing under a safety
shower. Obtain immediate medical attention.
4.3 INGESTION: DO NOT INDUCE VOMITING. If victim is conscious, immediately give large quantities of
water. If vomiting does occur, continue to give fluids. Obtain immediate medical attention.
4.4 INHALATION: Remove victim from contaminated atmosphere. If breathing is labored, administer
oxygen. If breathing has ceased, clear airway and start mouth to mouth resuscitation. If heart has stopped
beating, external heart massage should be applied. Obtain immediate medical attention.
Section 5: FIRE FIGHTING MEASURES
5.1 FLAMMABLE PROPERTIES
FLASH POINT: Not flammable (See Section 5.4) METHOD USED: NA
5.2 FLAMMABLE LIMITS H 2S LFL: 4% UFL: 44%
NH3 LFL: 16% UFL: 28%
5.3 EXTINGUISHING MEDIA: Water spray or foam or as appropriate for combustibles involved in fire.
Section 5: FIRE FIGHTING MEASURES (Cont.)
5.4 FIRE & EXPLOSIVE HAZARDS: .When heated or diluted ammonia vapors and hydrogen sulfide vapors
will evolve. Both of these gases may form explosive mixtures with air. (See Section 5.2) Keep
containers/storage vessels in fire area cooled with water spray.
5.5 FIRE FIGHTING EQUIPMENT: Because of the possible presence of toxic gases and the corrosive nature
of the product, wear self-contained breathing apparatus, pressure demand, MSHA/NIOSH (approved or
equivalent) and full protective gear.
Section 6: ACCIDENTAL RELEASE MEASURES
6.1 Small releases: Confine and absorb small releases on sand, earth or other inert absorbent. Released
material may contain residual sulfides. Spray with weak (~5%) hydrogen peroxide to oxidize sulfides.
6.2 Large releases: Confine area to qualified personnel. Wear proper protective equipment. Shut off
release if safe to do so. Dike spill area to prevent runoff into sewers, drains (possible explosive mixtures) or
surface waterways (potential aquatic toxicity). Spray product vapors with water spray or mist. Recover as
much of the solution as possible. Treat remaining material as a small release (above).
Section 7: HANDLING and STORAGE
7.1 Handling: Handle in enclosed containers to avoid breathing product. Avoid contact with skin and eyes.
Dilute only in enclosed containers. Use in a well ventilated area. Wash thoroughly after handling.
7.2 Storage: Store in well ventilated areas in enclosed containers. Do not store combustibles in the area of
storage vessels. Keep away from any sources of heat or flame. Store tote and smaller containers out of
direct sunlight at moderate temperatures [<90篎 (32篊)]. (See Section 10.4 for materials of construction)
Section 8: EXPOSURE CONTROLS, PERSONAL PROTECTION
8.1 RESPIRATORY PROTECTION: Wear self-contained breathing apparatus, pressure demand,
MSHA/NIOSH (approved or equivalent).
8.2 SKIN PROTECTION: Gloves, boots, and chemical suit should be worn to prevent liquid contact. Wash
contaminated clothing prior to reuse. Contaminated shoes cannot be cleaned and should be discarded
8.3 EYE PROTECTION: Chemical goggles and a full face shield.
8.4 EXPOSURE GUIDELINES: OSHA ACGIH
TWA STEL TLV STEL
Ammonia 25 ppm 35 ppm 25 ppm 35 ppm
Hydrogen sulfide 20 ppm (ceiling) 10 ppm (ceiling)
8.5 ENGINEERING CONTROLS: Use adequate exhaust ventilation to prevent inhalation of product vapors.
Maintain eyewash/safety shower in areas where chemical is handled.
Section 9: PHYSICAL and CHEMICAL PROPERTIES
9.1 APPEARANCE: Ruby red liquid
9.2 ODOR: Strong ammonia odor.
9.3 BOILING POINT: 100 癋(38 癈)
9.4 VAPOR PRESSURE: 314 mm Hg @ 70 癋 (21.1 癈)
9.5 VAPOR DENSITY: Not determined
9.6 SOLUBILITY IN WATER: Dissolves with precipitation of elemental sulfur.
9.7 SPECIFIC GRAVITY: 1.125 - 1.155 (9.4 - 9.6 lbs/gal)
9.8 FREEZING POINT: 32?- 42?F (0?- 5.6?C)
9.9 pH: 10.8 - 11.5
9.10 VOLATILE: Not applicable
Section 10: STABILITY and REACTIVITY
10.1 STABILITY: This is a stable material
10.2 HAZARDOUS POLYMERIZATION: Will not occur.
10.3 HAZARDOUS DECOMPOSITION PRODUCTS: Heating this product will initially evolve ammonia. As
the pH of the solution decreases more hydrogen sulfide vapors will evolve. Continued heating will also cause
oxides of nitrogen to be released.
10.4 INCOMPATIBILITY: Strong oxidizers such as nitrates, nitrites or chlorates can cause explosive
mixtures if heated to dryness. Acids will cause the release of hydrogen sulfide and ammonia, highly toxic
gases. Alkalies will accelerate the evolution of ammonia. Ammonium polysulfide is not compatible with
copper, zinc or their alloys (i.e. bronze, brass, galvanized metals, etc.). These materials of construction
should not be used in handling systems or storage containers for this product. (SEE Section 7.2, Storage)
