Dust and micro particles may
EFFECTS OF ACUTE: EYES:
cause eye irritation.
OVEREXPOSURE:
Frequent and prolonged
SKIN:
contact with dust may
aggravate preexisting
dermatitis and possibly
promote an allergic reaction.
Excessive inhalation of the dust
INHALATION:
may cause sore throat,
coughing and irritation of
mucous membranes and the
respiratory tract.
Abdominal pain, nausea,
INGESTION:
vomiting and gastrointestinal
irritation may result. ( Urea is a
protein to ruminants, animal
with the enzyme Urease in their
digestive systems, but is toxic
to humans)

Urea 鈥? Ultra LBU TM: Emergency First Aid Procedures
Immediately flush with large amounts of water, including under the
EYE CONTACT:
eyelids. If pain persists seek medical attention, preferably an
Ophthalmologist. Speed and thoroughness in rinsing eyes are
important to avoid permanent injury.
Immediately remove contaminated clothing and shoes. Wash the
SKIN CONTACT:
affected area with soap and flush with large amounts of water. Seek
medical attention if irritation develops.
Remove to fresh air. If breathing has stopped, apply artificial
INHALATION:
respiration. Keep warm and at rest. Get immediate medical attention.
Do not induce vomiting. If vomiting occurs, keep head below hips to
INGESTION:
help prevent aspiration. Get immediate medical attention.
Urea 鈥? Ultra LBU TM: Special Protection Information
Urea is water soluble and will dissolve with mucosal membrane
EYE PROTECTION:
contact (eyes). Remove contact lenses and wear safety glasses,
chemical goggles or face shield where contact with dust or micro
particles may occur.
Urea is water soluble and will dissolve with perspiration contact.
SKIN PROTECTION:
Wearing of appropriate protective clothing and gloves is suggested if
epidermal sensitivity develops.
Urea is water soluble and will dissolve with mucosal membrane
INHALATION:
contact (lungs). Use approved respiratory protective equipment for
cleaning large spills or upon entry into large tanks, vessels, and other
designated confined space areas or in any situations where airborne
3
concentrations may exceed occupational exposure limits (15 mg/m ).
Provide adequate general and local exhaust ventilation to avoid
VENTILATION:
reaching occupational exposure limits, particularly in a confined space
area.
Urea 鈥? Ultra LBU TM: Spill or Leak
Shovel spilled material into containers for disposal. Do not flush to surface water. Spilled
SPILL PROCEDURES:
chemical can be used as fertilizer (46-0-0)
Urea 鈥? Ultra LBU TM: Waste Disposal
Dispose of through a licensed waste disposal company. Follow federal, state and local
PROCEDURE:
regulations.
Urea 鈥? Ultra LBU TM: Special Precautions and Comments
Store away from incompatible materials or sources of heat and ignition. Empty containers may
STORAGE PRECAUTIONS:
contain residue and can be dangerous. 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.
