Water CAS #:7732-18-5 71 - 76%
(See Section 8 for exposure guidelines)
Section 3: HAZARDS IDENTIFICATION
NFPA: Health - 2 Flammability - 0 Reactivity - 1
Avoid inhalation of product fumes (hydrogen sulfide) near openings on storage
container. Release of the product to the environment may cause the evolution of highly toxic
hydrogen sulfide vapors. Product solution is alkaline and may cause irritation to the skin. Eye
contact will cause eye irritation and possible corneal damage. Ingestion will result in
irritation of tissues and the release of hydrogen sulfide in 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 (hydrogen sulfide) may 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 H2S LFL: 4% UFL: 44%
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, hydrogen sulfide vapors will evolve. This gas
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 irritating nature
of the product, wear self-contained breathing apparatus, positive pressure, (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 toxic or explosive
mixtures) or surface waterways (potential aquatic toxicity). Spray product vapors with fine 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, drums and small containers out of
direct sunlight at moderate temperatures [<90潞F (32潞C)]. (See Section 10.4 for materials of construction)
Section 8: EXPOSURE CONTROLS, PERSONAL PROTECTION
8.1 RESPIRATORY PROTECTION: Have self-contained breathing apparatus, positive pressure,
MSHA/NIOSH (approved or equivalent) available in case of spillage or equipment failure.
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:
TWA STEL TLV STEL
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

Section 10: STABILITY and REACTIVITY
10.1 STABILITY: This is a stable material
10.2 HAZARDOUS POLYMERIZATION: Will not occur.

vapors. Continued heating will also cause oxides of sulfur to be released.
10.4 INCOMPATIBILITY: Strong oxidizers such as nitrates, nitrites or chlorates can cause explosive mixtures
if heated to dryness. Acids, acidic materials or dilution with water will cause the release of hydrogen sulfide, a
highly toxic gas.
