INGESTION: Call a poison control center or doctor immediately for treatment advice. Have person sip a
glass of water if able to swallow. Do not induce vomiting unless told to do so by the poison control center
or doctor. Do not give anything by mouth to an unconscious person.
NOTES TO MEDICAL DOCTOR: Pendimethalin is a strongly orange-red colored compound. – virtually an
aniline dye. Cases have been described of orange-yellow coloration of urine following heavy exposure of
workers to the dust of pendimethalin. Despite its structure as both a nitro-compound and aromatic amine,
exposure to pendimethalin is NOT associated with methemoglobinemia. Treat symptomatically.
V. FIRE FIGHTING MEASURES
Flash Point (Method Used): NA Auto Ignition Temperature: NA
Lower Explosion Limits: NA Upper Explosion Limits: NA
NFPA/HMIS Rating: Health: 2
Fire: 1 Reactivity: 0
EXTINGUISHING MEDIA:
x Foam Alcohol Foam x CO
2
x Dry Chemical x Water Fog Other
EXPLOSION HAZARDS: Organic dusts may form an explosive dust/air mixture. Contamination with
strong acids may create an explosion hazard.
FIRE FIGHTING PROCEDURES: Firefighters should be equipped with self-contained breathing apparatus
and turnout gear. Avoid breathing dusts, vapors and fumes from burning materials. Control run-off water. If
water enters a drainage system, advise authorities downstream. Fertilizer will become slippery when wet.
Guard against falls.
HAZARDOUS COMBUSTION PRODUCTS: At high temperatures, nitrogen containing fertilizer can form
cyanuric cid, hydrogen cyanide and ammonia. Ammonium carbamate may also be formed.
VI. ACCIDENTAL RELEASE MEASURES
RELEASE NOTES: If material is spilled, evacuate are and ventilate. Wear protective equipment. If dry,
sweep or shovel into a container for reuse per label instructions, or disposal. If liquid, contain spill and
absorb with inert material and place in container for disposal. Prevent run-off from entering drains, sewers
or water sources. Avoid contact with skin, eyes, and clothing.
VII. HANDLING AND STORAGE
GENERAL PROCEDURES: Store in original container in a cool, dry secured storage area. Do not
contaminate water, foodstuffs, feed or seed by storage or disposal. Avoid contact with eyes, skin or
clothing. Keep away from heat, sparks, or other ignition sources.
OTHER PRECAUTIONS: Avoid inhalation of dust. Wash thoroughly with soap and water after handling.
Keep out of reach of children.
VIII. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS: Work in well ventilated areas. Whenever possible, engineering controls
should be used to minimize the need for personal protective equipment.
PERSONAL PROTECTION EQUIPMENT:
EYES AND FACE: Chemical goggles when respirator does not provide eye protection.
RESPIRATORY: NIOSH/MSHA approved respirator should be worn if large quantities of dust are
generated or prolonged exposure possible.
GLOVES: Chemical resistant gloves
PROTECTIVE CLOTHING: Long-sleeved shirt and long pants, shoes plus socks

changing/maintaining PPE. If no such instructions exist for washables, use detergent and hot water. Keep
and wash PPE separately from other laundry.
COMMENTS: Have eye washing facility readily available where eye contact can occur.
