UNUSUAL FIRE AND EXPLOSION HAZARDS:
None.
SPECIAL FIRE FIGHTING PRECAUTIONS/INSTRUCTIONS:
Use self-contained breathing apparatus. Use water spray to keep containers cool.
6. ACCIDENTAL RELEASE MEASURES
IN CASE OF SPILL OR OTHER RELEASE: (See section 8 for recommended personal protective equipment.)
Dilute small spills or leaks cautiously with plenty of water. Neutralize any further residue with alkali such as soda
ash, lime or limestone. Adequate ventilation is required if soda ash or limestone is used, because of the
consequent release of carbon dioxide gas. Large spills: dike up with soda ash and neutralize as above. Collect
liquid and/or residue and dispose of in accordance with applicable regulations.
Spills and releases may have to be reported to Federal and/or local authorities. See Section 15 regarding
reporting requirements.

7. HANDLING AND STORAGE
NORMAL HANDLING: (See section 8 for recommended personal protective equipment.)
Avoid contact with skin, eyes and clothing. Do not breathe product mists.
STORAGE RECOMMENDATIONS:
Store in a cool area.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS:
Use local exhaust if misting is anticipated.
PERSONAL PROTECTIVE EQUIPMENT
Wear impervious (e.g. rubber) gloves and apron and full work clothing including long
SKIN PROTECTION:
sleeved shirts, trousers and boots. Full impervious clothing is recommended if
prolonged product contact is anticipated.
Wear chemical safety goggles. Do not wear contact lenses.
EYE PROTECTION:
A NIOSH approved mist respirator should be worn in areas where product mists are
RESPIRATORY
present.
PROTECTION:
The presence of an eyewash and safety shower is recommended.

10. STABILITY AND REACTIVITY
NORMALLY STABLE? (CONDITIONS TO AVOID):
Normally stable. If evaporated to dryness, residue should not be exposed to elevated temperatures (above 760潞C),
as this will yield toxic and corrosive gases.
INCOMPATIBILITIES:
Alkalis and water reactive materials such as oleum: causes exothermic reactions.
HAZARDOUS DECOMPOSITION PRODUCTS:
At elevated temperatures, sulfur oxides may be formed. These are toxic and corrosive and are oxidizers. Sulfur
trioxide is also a fire hazard. The loss of these gases leaves a caustic residue.
HAZARDOUS POLYMERIZATION:
Will not occur
