Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing 
and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse. 
EYES: 
Immediately flush eyes with plenty of water for at least fifteen minutes, lifting lower and upper eyelids occasionally. 
Get medical attention immediately.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION 
AIRBORNE EXPOSURE LIMITS: 
Component: Urea 
10 mg/m3, 8-hour TWA ACGIH Threshold Limit Value (TLV): 
not available OSHA Permissible Exposure Limit (PEL): 
ENGINEERING CONTROLS 
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborn 
Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the 
contaminant at its source. 
RESPIRATORY PROTECTION 
For conditions of use where exposure to the dust or mist is apparent, a full-face dust/mist respirator may be worn. 
For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, airsupplied 
respirator. 
EYE PROTECTION 
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and 
quick-drench facilities in work area. 
SKIN PROTECTION 
Wear protective gloves and clean body covering clothing.

HAZARDOUS DECOMPOSITION PRODUCTS 
Urea decomposes upon heating and can form products including ammonia, oxides of nitrogen, cyanuric acid, 
cyanic acid, biuret, and carbon dioxide. 
HAZARDOUS POLYMERIZATION 
Will not occur 
INCOMPATIBLES 
Urea reacts with calcium hypochlorite or sodium hypochlorite to form the explosive nitrogen trichloride. It is 
incompatible with sodium nitrite, gallium perchlorate, strong oxidizing agents (permanganate, dichromate, nitrate, 
chlorine), phosphorus penta

12. ECOLOGICAL INFORMATION 
When urea is released to soil, this material will hydrolyze into ammonium in a matter of days to several weeks. When 
released into the soil, this material may leach into groundwater. When released into water, this material may 
biodegrade to a moderate extent. When released into water, this material is not expected to evaporate significantly. 
This material has an experimentally determined bioconcentration factor (BCF) of less than 100. This material is not 
expected to significantly bioaccumulate. When released into the air, this material is expected to be readily degraded by 
reaction with photochemically produced hydroxyl radicals. When released into the air, this material is expected to have 
a half-life of less than 1 day. 
13. DISPOSAL CONSIDERATIONS 
Observe all national, state, and local regulations regarding disposal.
