SECTION VI - TOXICITY DATA
Route Test Dose
oral-rat LD50 55 mg/kg moderately toxic
oral-mouse LD50 165 mg/kg
skin-rabbit LD50 175 mg/kg highly toxic
inhal-rat LC50 180 mg/m3 highly toxic
Occupational Exposure: No exposure limits have been set by OSHA, NIOSH or ACGIH.
Carcinogen: IARC: NO, NTP: NO, OSHA: NO
SECTION VII - HEALTH HAZARD INFORMATION
Primary Routes of Exposure:
Monochloroacetic acid is highly toxic by absorption thru any route of exposure. Human fatality has
resulted from contact over 10% of body surface.
In animal tests MCA was found to be lethal with 3% body coverage.
Ingestion: High, single-dose oral toxicity. Undiluted material will severely burn mucous membranes.
Eye Contact: Can cause severe corneal damage with possible permanent impairment of vision.
Skin Contact: Brief contact causes a severe burn that can be slow to heal.
Readily absorbed in highly toxic amounts.
Inhalation: Irritation will result from the inhalation of the vapors.
Effects of Overexposure:
Systemic poison. Symptoms may be delayed after exposure.
Depressant of the central nervous system. Symptoms include: abdominal cramps, asphyxia, dyspnea,
pneumonia, skin burns, skin necrosis, neoplasm, respiratory distress, angina pectoris, cough, respiratory
edema and pharyngitis.

SECTION VIII - EMERGENCY FIRST AID PROCEDURES
Ingestion: If person is conscious, give water or milk to dilute stomach contents.
Get immediate medical attention!
Eye Contact: Immediate and continuous irrigation with flowing water (hold eyelids open) for
at least 30 minutes is imperative. Get immediate medical attention!
Skin Contact: Immediate removal of contaminated clothing and continuous washing of
affected area with flowing water is imperative to prevent serious injury or
death. Get immediate medical attention!
Destroy all contaminated clothing and shoes.
Inhalation: Remove to fresh air. Administer artificial respiration if breathing has stopped.
Get immediate medical attention!
SECTION IX - EMPLOYEE PROTECTION
Protective Clothing: Clothing suitable to prevent skin contact. If chance of exposure exists a plastic or
neoprene rain suit should also be worn.
Eye Protection: Chemical goggles and a full face shield.
Contact lenses should not be worn when working with this material.
Respiratory Protection: Recommend control of vapors with local ventilation, use a caustic scrubber.
If airborne concentrations become irritating use a NIOSH approved respirator.
Eye wash safety shower at the work station.
SECTION X - SPILL AND DISPOSAL PROCEDURES
Action to be Taken for Spills:
Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind. Positive pressure, self-
contained breathing apparatus and chemical protective clothing is recommended. Structural firefighters'
protective clothing is NOT effective for these materials. Contain spill with earthen dike. Pump solution to
a suitable container. Neutralize area with soda ash. Collect spent soda ash for disposal. Wash down
neutralized area of spill with large quantities of water.
Disposal Methods:
Neutralized material is readily biodegradable. Dispose of in accordance with applicable Federal, state and
local regulations. This material is defined as a hazardous substance under CERCLA.
