UNUSUAL FIRE AND EXPLOSION HAZARDS:

None.

SPECIAL FIRE FIGHTING PRECAUTIONS/INSTRUCTIONS:

Use self-contained breathing apparatus.

6. ACCIDENTAL RELEASE MEASURES

IN CASE OF SPILL OR OTHER RELEASE: (See section 8 for recommended personal protective equipment.)

Shovel up dry chemical and place in empty container and cover. Spray residue 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. 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 dusts or mists.

MATERIAL SAFETY DATA SHEET

STORAGE RECOMMENDATIONS:

Store in a cool, dry area.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

ENGINEERING CONTROLS:

Use local exhaust if dusty or misty conditions prevails.

PERSONAL PROTECTIVE EQUIPMENT

SKIN PROTECTION: Wear gloves and appropriate industrial work clothing including long sleeved shirts

and trousers for routine product handling. Full impervious clothing is recommended

if handling solutions and there is repeated or prolonged contact.

EYE PROTECTION: Wear chemical safety goggles. Do not wear contact lenses.

RESPIRATORY

PROTECTION:

A NIOSH approved dust or mist respirator should be worn in areas where product

dusts or mists are present.

ADDITIONAL

RECOMMENDATIONS:

The presence of an eyewash and safety shower is recommended.
