First Aid Measures
Emergency procedures for chemical exposure incidents
Remove to fresh air. If not breathing, give artificial respiration or give oxygen by trained personnel. Keep warm. Get immediate medical attention.
Immediately wash skin with plenty of water for at least 20 minutes, while removing contaminated clothing and shoes. Get medical attention especially, if irritation develops, persists, or symptoms of overexposure become apparent.
Immediately flush eyes with plenty of water for at least 20 minutes. Assure adequate flushing of the eyes by separating the eyelids with fingers. Get immediate medical attention if irritation persists, or symptoms of overexposure become apparent.
If swallowed, call a physician or poison control center immediately. Never give anything by mouth to an unconscious person. Do not induce vomiting unless instructed by medical personnel. Get medical attention.
Immediate Medical Attention
Get immediate medical attention if irritation persists, or symptoms of overexposure become apparent (eyes); Get medical attention especially, if irritation develops, persists, or symptoms of overexposure become apparent (skin); Get immediate medical attention (inhalation); Get medical attention (ingestion).
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Use dry powder or carbon dioxide when fighting a fire involving this material.
Water extinguishers are not recommended.
Firefighter Protection
As in any fire, wear self-contained breathing apparatus pressure-demand, NIOSH (approved or equivalent) and full protective gear.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Clean up spills immediately, observing precautions in the Protective Equipment section.
Do not allow material to enter drains or streams.
Absorb spill with dry inert material such as dry sand, earth, or vermiculite, then place in suitable container.
Materials: dry sand, earth, or vermiculite

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
This product should be handled only by, or under the close supervision of, those properly qualified in the handling and use of potentially hazardous chemicals, who should take into account the fire, health and chemical hazard data. Care should be taken to prevent any chemical from coming into contact with the skin or eyes and from contaminating personal clothing.
Store in a cold, below 5 degrees celcius, dry, well ventilated area away from sources of heat and incompatible substances. Keep container tightly closed and cold when not in use.
Wash thoroughly after handling. Avoid contact with eyes and skin. Avoid inhaling vapor or mist.
Store away from sources of heat.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Use appropriate engineering control such as process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits.
Wear appropriate protective gloves. Consult glove manufacturers for glove permeability data.
Wear appropriate protective glasses or splash goggles as described by 29 CFR 1910.133, OSHA eye and face protection regulation, or the European standard EN 166.
A NIOSH approved air-purifying respirator with an appropriate cartridge or canister may be permissible under certain circumstances where airborne concentrations are expected to exceed exposure limits. Protection provided by air purifying respirators is limited to airborne concentrations that are typically within 10 times the exposure limit. Use a positive pressure air supplied respirator if there is any potential for an uncontrolled release, exposure levels are not known, or any other circumstances where air-purifying respirators may not provide adequate protection. A respiratory protection program that meets OSHAs 29 CFR 1910.134 and ANSI Z88.2 requirements must be followed whenever workplace conditions warrant a respirators use.
Wear suitable protective clothing to prevent contact with skin.
