EMERGENCY OVERVIEW
Harmful in contact with skin and if swallowed. Toxic by inhalation.
Causes burns. May cause fire. Harmful : danger of serious damage to health by prolonged exposure through inhalation and if swallowed.
Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.
Potential Health Effects
Eye:
Causes eye burns.
Skin:
Harmful if absorbed through the skin. Causes skin burns.
Ingestion:
Harmful if swallowed. Causes gastrointestinal tract burns.
Inhalation:
Causes chemical burns to the respiratory tract. Toxic if inhaled.
May cause respiratory difficulty and coughing.
Chronic:
Not available.

Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
Do not induce vomiting. Get medical aid. Wash mouth out with water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.

General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Strong oxidizer. Contact with other material may cause fire. Will burn if involved in a fire.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Remove all sources of ignition.

Handling:
Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in a chemical fume hood. Avoid mechanical shock and friction.
Storage:
Keep away from sources of ignition. Do not store near combustible materials. Store in a tightly closed container. Store in a dry area.
Keep refrigerated. (Store below 4C/39F.) Keep away from reducing agents.

Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
Exposure Limits CAS# 80-15-9: Russia: 1 mg/m3 TWA Personal Protective Equipment Eyes: Not available.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
