treatment advice.
IF SWALLOWED: Call a poison control center or doctor immediately for treatment advice. Have a person sip a glass of
water if able to swallow. Do not induce vomiting unless told to do so by a poison control center or doctor. Do not give
anything by mouth to an unconscious person.
IF INHALED: Move person to fresh air. If not breathing, call 911 or an ambulance, then give artificial respiration,
preferably mouth-to mouth. Call a poison control center or doctor for treatment advice.

EXTINGUISHING MEDIA AND FIRE FIGHTING INSTRUCTION
Vapors and products of combustion are corrosive to the respiratory tract and may cause breathing difficulty and pulmonary
edema. As in any fire, prevent human exposure to fire, smoke, fumes or products of combustion. Evacuate nonessential
personnel from the fire area. Firefighters should wear full-face, self-contained breathing apparatus and impervious
protective clothing. Use standard fire-fighting techniques to extinguish fires involving this material. Use water, dry
chemicals, foam or carbon dioxide. If drums are NOT leaking, keep cooled with a water spray. High-pressure water hoses
may spread product from broken containers, increasing contamination hazard. Contaminated building, areas and
equipment must not be used until they are properly decontaminated. If fire cannot be controlled and containers are heated,
EVACUATE THE AREA!
6. ACCIDENTAL RELEASE MEASURES
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED
Make sure all personnel involved in the spill cleanup follow good industrial hygiene practices. Any person entering an area
of a significant spill or of an unknown concentration of an aerosol should use a NIOSH approves, positive pressure self-
contained breathing apparatus or a NIOSH approved positive pressure air supplied respirator with escape pack. Small spills
can be handle routinely. Use adequate ventilation and or wear a NIOSH approved organic vapor respirator with dust mist
and fume filter to prevent inhalation exposure. Wear protective clothing to prevent skin and eye contact. Use the following
procedures: Soak up pooled liquid with a suitable absorbent such as clay, sawdust kitty litter or fuller's earth. Sweep up the
absorbed material and place into an appropriate chemical waste container for disposal. Generously cover contaminated area
with slurry of common, powdered household laundry detergent and water. Using a stiff brush, work the slurry into cracks
and crevices. Allow to stand for 2-3 minutes then flush with water. Repeat if necessary. Large spills must be handled
according to a predetermined plan.
7. HANDLING AND STORAGE
Storage Requirements: Containers should be stored at room temperature in dry, well-ventilated area away from
flammable materials and sources of heat or flame. Store away from foodstuffs or animal feed. Exercise due caution to
prevent damage to or leakage from the container. Avoid prolonged storage at temperatures above 158oF (70oC).
Containers should not be opened until ready for use.
8. PERSONAL PROTECTION
EYE PROTECTION REQUIREMENTS: Protective eyewear / goggles and full-face shield.
SKIN PROTECTION REQUIREMENTS: Long-sleeved shirt and long pants, socks, Chemical-resistant footwear and
gloves.
VENTILATION REQUIREMENTS: Use local exhaust ventilation where vapor may be generated.
RESPIRATOR REQUIREMENTS: For irritating vapors, use a NIOSH approved respirator in accordance with OSHA
regulations.

your State Pesticide or Environmental Control Agency, or the Hazardous Waste representative at the nearest EPA Regional
Office for guidance.
CONTAINER DISPOSAL: PLASTIC CONTAINERS: Triple rinse (or equivalent). Then offer for recycling or
reconditioning, or puncture and dispose of in a sanitary landfill, or incineration, or if allowed by state and local authorities,
