Hazards and Protection.
Storage
Keep tightly closed in a cool place in a tightly closed container.
Handling
Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed.
Protection
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Consult your safety representative. Wear resistant gloves such as: polyvinyl chloride, To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Respirators
Not required under normal conditions of use.
Small spills/leaks
Small Spill - Absorb liquid on vermiculite, floor absorbent or other absorbent material. Flush area with water. Large Spill - Persons not wearing protective equipment should be excluded from area of spill until clean-up is completed. Stop spill at source. Dike to prevent spreading. Pump to salvage tank.

Fire fighting
Extinguish fire using alcohol foam, carbon dioxide, dry chemical. Water or foam may cause frothing which can be violent and possibly endanger the life of the firefighter. Water may be used to keep fire-exposed containers cool until fire is out. Wear a self-contained breathing apparatus with a full facepiece operated in the positive pressure demand mode with appropriate turn-out gear and chemical resistant personal protective equipment. Refer to the personal protective equipment section of this MSDS.
Fire potential
Slightly flammable. Combustion requires preheating. Moderate hazard.

Exposure effects
   Ingestion
Swallowing small amounts of this material during normal handling is not likely to cause harmful effects. Swallowing large amounts may be harmful.
   Inhalation
Irritation.
   Skin
May cause mild skin irritation. Prolonged or repeated contact may dry the skin. Symptoms may include redness, burning, drying and cracking of skin, and skin burns.
   Eyes
May cause mild eye irritation. Symptoms include stinging, tearing, and redness.

First aid
 
   Ingestion
Emesis is contraindicated due to rapid gi absorption and potential for rapid progression to coma. Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Correct severe acidosis (ph < 7.1) With iv nahco3. 1 To 2 meq/kg is a useful starting dose. Monitor abgs. Ethanol (etoh) may inhibit the formation of toxic metabolites, but there are no controlled human studies documenting efficacy. Loading dose - administer 7.6 To 10 ml/kg of 10% etoh in d5w iv over 30 minutes. Maintenance dose - administer 1.39 Ml/kg/hr of 10% etoh in d5w by iv infusion. Aim at achieving and maintaining 100 to 130 mg/dl blood ethanol levels.
   Inhalation
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
   Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
