Risk Phrases: 22 36/37/38
Section 3 - Hazards
Appearance: white. Danger! May cause kidney damage. May
cause severe digestive tract irritation with possible burns. May be harmful if
swallowed or absorbed through the skin. Causes eye and skin irritation and
possible burns. Causes respiratory tract irritation and possible burns.
Target Organs: Kidneys.
Eye: May result in corneal injury.
Contact with eyes may cause severe irritation, and possible eye burns.
Skin: Contact with skin causes irritation and possible
burns, especially if the skin is wet or moist. May cause dermatitis. May be
harmful if absorbed through the skin.
Ingestion: May cause
severe and permanent damage to the digestive tract. Causes gastrointestinal
tract burns. May cause kidney damage. May be harmful if swallowed.
Inhalation: May cause severe irritation of the respiratory
tract with sore throat, coughing, shortness of breath and delayed lung edema.
Causes chemical burns to the respiratory tract.
Overexposure may cause delayed kidney injury.
Section 4 - First Aid
Eyes: Flush eyes with plenty of water for at least
15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid
immediately. Do NOT allow victim to rub or keep eyes closed. Extensive
irrigation with water is required (at least 30 minutes).
Skin: Get medical aid immediately. Immediately flush skin
with plenty of soap and water for at least 15 minutes while removing
contaminated clothing and shoes. Wash clothing before reuse. Destroy
Ingestion: Do NOT induce vomiting. If
victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical
Inhalation: Get medical aid immediately.
Remove from exposure to fresh air immediately. If breathing is difficult, give
oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device such as a
bag and a mask.
Notes to Physician: Treat symptomatically
Section 5 - Fire
Information: As in any fire, wear a self-contained breathing apparatus
in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective
gear. During a fire, irritating and highly toxic gases may be generated by
thermal decomposition or combustion. May accumulate static electrical charges,
and may cause ignition of its own vapors. Runoff from fire control or dilution
water may cause pollution.
Extinguishing Media: For small
fires, use water spray, dry chemical, carbon dioxide or chemical foam.
Section 6 -
Accidental Release Measures
Information: Use proper personal protective equipment as indicated in
Spills/Leaks: Clean up spills immediately,
observing precautions in the Protective Equipment section. Wear a self contained
breathing apparatus and appropriate Personal protection. (See Exposure Controls,
Personal Protection section). Sweep up, then place into a suitable container for
disposal. Avoid generating dusty conditions. Provide ventilation.
Section 7 - Handling
Handling: Wash thoroughly after handling. Remove
contaminated clothing and wash before reuse. Minimize dust generation and
accumulation. Do not get in eyes, on skin, or on clothing. Keep container
tightly closed. Do not ingest or inhale. Use with adequate ventilation. Discard
Storage: Keep away from sources of
ignition. Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Corrosives area.
Section 8 - Exposure
Controls, Personal Protection
Controls: Facilities storing or utilizing this material should be
equipped with an eyewash facility and a safety shower. Use adequate ventilation
to keep airborne concentrations low.
OSHA Vacated PELs: Maleic
acid: No OSHA Vacated PELs are listed for this chemical.
Eyes: Wear appropriate
protective eyeglasses or chemical safety goggles as described by OSHA's eye and
face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin: Wear appropriate protective gloves to prevent skin
Clothing: Wear appropriate protective clothing to
minimize contact with skin.
Respirators: A respiratory protection
program that meets OSHA's 29 CFR §1910.134 and ANSI Z88.2 requirements or
European Standard EN 149 must be followed whenever workplace conditions warrant
a respirator's use.

released on land, maleic acid will leach into the ground and probably
biodegrade. While maleic acid is readily biodegraded, no degradability data were
found for soil systems. If released into water, maleic acid will probably
biodegrade based on the results of screening studies. No biodegradability
studies were found in environmental waters. Adsorption to sediment and
volatilization should not be significant.
Physical: Due to its polar
nature, maleic acid released into the atmosphere will be primarily associated
with aerosols. It will be subject to gravitational settling and also degrade by
reaction with ozone and photochemically produced hydroxyl radicals (half-life
Other: The BCF of maleic acid in fish (golden ide) was
<10 after 3 days of exposure while that in algae (Chorella fusca) was 11
after 24hr. The BCF calculated from the water solubility (788 g/l) using a
reommended regression equation is 3, which indicates the bioconcentration should
not be an important process.
Section 13 - Disposal
