Section 3: HAZARDS IDENTIFICATION
NFPA: Health - 1 Flammability - 0 Reactivity - 1
EMERGENCY OVERVIEW
Solutions are slightly acidic (pH 5.5)
Contact may cause eye irritation.
Repeated/prolonged skin contact may cause irritation.
Avoid inhalation of fumes in vapor space (sulfur dioxide).
Ingestion may irritate gastrointestinal tract.
Heating may lead to rapid thermal decomposition resulting in
release of heat, SO2, and associated gas pressure.

Section 3: HAZARDS IDENTIFICATION
3.1 POTENTIAL HEALTH EFFECTS
EYE: Contact with the eyes by product mist or solution will cause irritation and a burning sensation.
SKIN CONTACT: Prolonged or repeated contact with product mist or solution will cause skin irritation.
SKIN ABSORPTION: Absorption is unlikely to occur.
INGESTION: Ingestion of product solution will cause irritation of the gastrointestinal tract to include nausea,
vomiting and diarrhea.
INHALATION: Inhalation of product vapors (slight amount of sulfur dioxide) will cause nose, throat and lung
irritation..
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: If victim is conscious, immediately give 2 to 4 glasses of water. Induce vomiting by
touching finger to back of throat. 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 METHOD USED: NA
5.2 FLAMMABLE LIMITS LFL: NA UFL: NA
5.3 EXTINGUISHING MEDIA: As appropriate for combustibles involved in fire.
5.4 FIRE & EXPLOSIVE HAZARDS: .When heated , sulfur dioxide vapors will evolve. This gas is a severe
respiratory hazard. Further heating may cause rapid thermal decomposition resulting in rapid release of heat,
sulfur dioxide and associated pressure. 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. Dispose of
in a chemical waste landfill.
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 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.
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 which may cause rapid thermal
decomposition resulting in rapid heat and pressure release. Avoid heating of ABS above 75掳F (24掳C), in
closed storage vessels. Provide for venting of closed pressure vessels. Store tote and smaller containers out
of direct sunlight at moderate temperatures [75掳F (24掳C)]. See Section 10.4 for materials of construction.
Section 8: EXPOSURE CONTROLS, PERSONAL PROTECTION
8.1 RESPIRATORY PROTECTION: None generally required. If vapor exposure is possible a NIOSH
approved respirator for sulfur dioxide is required. Wear self-contained breathing apparatus, pressure
demand, MSHA/NIOSH (approved or equivalent) if handling product under fire conditions.
8.2 SKIN PROTECTION: Neoprene rubber gloves, boots, and apron should be worn to prevent contact with
the liquid. Wash contaminated clothing prior to reuse.
8.3 EYE PROTECTION: Chemical goggles and a full face shield
8.4 EXPOSURE GUIDELINES:
OSHA ACGIH
TWA STEL TLV STEL
Sulfur dioxide 5 ppm 35 ppm 2 ppm 5 ppm (15 min)
8.5 ENGINEERING CONTROLS: Use adequate exhaust ventilation to prevent inhalation of product vapors.
Provide for adequate vents for storage in closed storage vessels. Maintain eyewash/safety shower in areas
where product is handled.

Section 9: PHYSICAL and CHEMICAL PROPERTIES
9.1 APPEARANCE: Clear to pale yellow liquid
9.2 ODOR: Slight sulfur dioxide odor.
9.3 BOILING POINT: 220潞 - 231潞 F (104潞 - 111潞 C)
9.4 VAPOR PRESSURE: Data not available
9.5 VAPOR DENSITY: Not determined
9.6 SOLUBILITY IN WATER: Complete
9.7 SPECIFIC GRAVITY: 1.253 - 1.380 (10.4 - 11.5 lbs/gal)
9.8 FREEZING POINT: Not determined
9.9 pH: 5.5
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 in a closed pressure vessel will
generate ammonium bisulfate, ammonium sulfate and sulfur. In an open container ammonium thiosulfate and
ammonium sulfate will be generated and sulfur dioxide will be vented.
10.4 INCOMPATIBILITY: Strong oxidizers such as nitrates, nitrites or chlorates. Acids will cause the release
of sulfur dioxide, a highly toxic gas. Alkalies will accelerate the evolution of ammonia. Ammonium bisulfite 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.
