Safety Data Sheet
Reactivity: Hazardous reactions will not occur under normal conditions.

Advice for Firefighters
Precautionary Measures Fire: Promptly isolate the scene by removing all persons from the vicinity of the incident if
there is a fire. Move containers from fire area if this can be done without risk. Use water spray to keep fire-exposed
containers cool. Collect contaminated fire-fighting water separately. It must not enter the sewage system. Exercise
caution when fighting any chemical fire.
Firefighting Instructions: Urea will not burn or support combustion but will decompose into noxious, poisonous gas
when exposed to the high temperatures of a fire. Firefighters should wear self-contained breathing apparatus and full
protective clothing.

Protection During Firefighting: Do not enter fire area without proper protective equipment, including respiratory
protection.
Hazardous Combustion Products: Ammonia and Nitrogen Oxides (Nitric Oxide and Nitrogen Dioxide).
Reference to Other Sections: Refer to section 9 for flammability properties.

SECTION 7 - HANDLING AND STORAGE
Precautions for Safe Handling
Store in compliance with all Federal, State, and local regulations. Store in a well-ventilated area, away from incompatible
materials or sources of heat and ignition. Empty containers may contain residue and can be dangerous if exposed to hot
work conditions. Do not pressurize, cut, weld, braze, solder, drill, grind or expose such containers to heat, flames, sparks
or other sources of ignition; they may evolve noxious fumes.

Hygiene Measures: Handle in accordance with good industrial hygiene and safety procedures. Wash hands and other
exposed areas with mild soap and water before eating, drinking or smoking and when leaving work.
Conditions for Safe Storage, Including Any Incompatibilities
Technical Measures: Comply with applicable regulations.
