Section 3 - HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW

Irritating to eyes.

Potential Health Effects

Eye: May result in corneal injury. Contact with eyes may cause severe

irritation, and possible eye burns.

Skin: Contact with skin causes irritation and possible burn, especially

if the skin is wet or moist.

Ingestion: May cause irritation of the digestive tract.

Inhalation:  Harmful if inhaled. May cause irritation of the respiratory tract

with burning pain in the nose and throat, coughing, wheezing,

shortness of breath and pulmonary edema.

Chronic: Prolonged or repeated inhalation may cause nosebleeds, nasal

congestion, erosion of the teeth, perforation of the nasal septum,

chest pain and bronchitis.

Section 4 - FIRST AID MEASURES

Eyes: Immediately flush eyes with plenty of water for at least 15 minutes,

occasionally lifting the upper and lower eyelids. Get medical aid

immediately.

Skin: Get medical aid. Flush skin with plenty of soap and water for at

least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.

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.

Inhalation: Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid if cough or other symptoms appear.

Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES

General Information:

As in any fire, wear a self-contained breathing apparatus in

pressure-demand, MSHA/NIOSH (approved or equivalent), and full

protective gear. Material will not burn. Wear appropriate protective

clothing to prevent contact with skin and eyes. Wear a self-contained

breathing apparatus (SCBA) to prevent contact with thermal

decomposition products.

Extinguishing Media:

Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. Use water fog, dry chemical, carbon dioxide or alcohol type foam.

Section 6 - ACCIDENTAL RELEASE MEASURES

General Information: Use proper personal protective equipment as indicated in Section 8.

Spills/Leaks: Vacuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions. Provide ventilation. Cover with material such as dry soda ash or calcium carbonate and

 place into a closed container for disposal

Section 7 - HANDLING and STORAGE

Handling:  Wash thoroughly after handling. Remove contaminated clothing and

wash before reuse. Do not get in eyes, on skin, or on clothing. Keep

container tightly closed. Avoid ingestion and inhalation

Storage: Store in a tightly closed container. Store in a cool, dry,

well-ventilated area away from incompatible substances

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION

Engineering Controls:

Good general ventilation should be sufficient to control airborne

levels.

Personal Protective Equipment

Eyes: Wear appropriate protective eyeglasses or chemical

safety goggles as described by OSHA's eye and face

protection regulations in 29 CFR 1910.133 or European

Standard EN166.

Skin: Wear appropriate protective gloves and clothing to

prevent skin exposure.

Clothing:  Wear appropriate protective clothing to minimize

contact with skin.

Respirators: Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
