Section IV 鈥? Fire and Explosion Hazard Data
Flash Point (Method Used): Not applicable Flammable Limits: LEL (Lower Explosive Limit) - N/A
UEL (Upper Explosive Limit) - N/A
Extinguishing Media: Suitable extinguishing agents. CO2, extinguishing powder, or water spray.
Special Fire Fighting Procedures: Fight larger fires with water or alcohol resistant foam. Firefighters should wear
protective equipment and self-contained breathing apparatus.
Unusual Fire and Explosion Hazards: During heating or in case of fire, poisonous gases (sulfur dioxide) are produced.
Closed containers exposed to heat may explode.
Section V 鈥? Reactivity Data
Unstable Conditions to Avoid: Keep away from heat and light. Decomposed by heat; reduces

Section VI 鈥? Health Hazard Data
Inhalation? Yes Skin? Yes Ingestion? Yes
Route(s) of Entry:
Harmful. Harmful if swallowed, inhaled, or absorbed through the skin. May cause allergic
Health Hazards:
respiratory reaction. Irritating to eyes, respiratory system and skin.
(Acute and Chronic)
Carcinogenicity: NTP? No IARC Monographs? Group 3 (Sodium Bisulfite) OSHA Regulated? No
(National Toxicology Program) The agent is not classifiable as to carcinogenicity in humans.
(International Agency for Research in Cancer)
Signs and Symptoms of Exposure: Irritant to skin and mucous membranes. Irritating effect to eye. This product
contains sulfites. People with known or suspected allergies to sulfite should use appropriate safety precautions when
handling, especially asthmatics. A severe allergic reaction may be fatal. If ingested, may cause gastric irritation by the
liberation of sulfurous acid.
Medical Conditions Generally Aggravated by Exposure: Sensitization possible through inhalation. If inhaled,
coughing and shortness of breath may result. Contact with skin or eyes may cause severe irritation or burns. Symptoms
may include redness, itching, and pain.
Ingestion: If swallowed, seek medical attention immediately.
Emergency /
First Aid
Inhalation: Supply fresh air or oxygen, seek medical attention. If not breathing, give artificial respiration.
Procedures:
If breathing is difficult, give oxygen.
Eye Contact: Rinse opened eye for at least 15 minutes under running water. Seek medical attention.
Skin Contact: Wash with plenty of soap and water for at least 15 minutes. Seek medical attention.
Section VII 鈥? Precautions for Safe Handling and Use
Accidental Release Measures: Wear suitable protective clothing. Ventilate area away from sources of heat, moisture
and incompatibilities. Flush spill area with water, wipe up with damp sponge or mop. Remove contaminated clothing.
Waste Disposal Method: Dispose in accordance with all applicable federal, state, and local environmental regulations.
Handling and Storing: Keep container tightly closed, in a cool, dry ventilated area. Protect from moisture. Protect
container from physical damage. Store away from oxidizing agents. Do not store together with acids.
Other Precautions: Prevent formation of dust. Ensure good ventilation / exhaustion at the workplace. Containers of this
material may be hazardous when empty since they retain product residues. Prevent repeated or prolonged exposure.
Section VIII 鈥? Control Measures
