SECTION VII– PREVENTIVE MEASURES

Personal Protective Equipment

 

Gloves (specify):  Wear appropriate gloves to prevent skin exposure.

Respiratory (specify): Follow OSHA regulations found in 29CFR 1910.134

Eye (specify): Wear eyeglasses or goggles as specified in OSHA eye and face regs. In 29CFR 1910.133

Footwear (specify)

Clothing (specify):  Wear appropriate clothing to prevent skin exposure.

Other (specify)

 

Engineering Controls (e.g., ventilation, enclosed process, specify)

Use adequate general or local exhaust ventilation to keep airborne concentrations below permissible exposure limits.

Leak & Spill Procedure

Clean up spills immediately, using appropriate personal protective equipment.  Cover spill with sand, dry lime, or soda ash.

Waste Disposal

Place used sand, lime, or soda ash use to adsorb spill or leak in a closed container for disposal.  Dispose of in a manner consistent with federal, state, and local regulations.

Handling Procedures & Equipment

Wash thoroughly after handling, remove contaminated clothing and wash before reuse.  Do not get in eyes, on skin, or on clothing.  Keep in a tightly closed container.  Do not allow contact with water.  Use only in a chemical fume hood.

Storage Requirements

Don not store near combustible materials.  Keep container closed when not in use.  Store in a cool, dry, well-ventilated area away from alkaline substances and other incompatible substances.

Special Shipping Information

 

SECTION VIII– FIRST AID MEASURES

Skin

Get medical aid immediately.  Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.  SPEEDY ACTION IS CRITICAL!

Eye

Get medical aid immediately.  Do not allow victim to rub or keep eyes closed.  Extensive irrigation is required (at least 30 minutes)

Inhalation

Get medical aid immediately.  Remove from exposure to fresh air immediately.  If breathing is difficult, give oxygen.

Ingestion

Do not induce vomiting.  If victim is conscious and alert, give 2-4 cupfuls of milk or water.  Never give anything by mouth to an unconscious person. Get medical aid immediately.
