SECTION 2: HAZARDOUS INGREDIENTS / IDENTITY INFORMATION
CAS NUMBER CHEMICAL IDENTITY %
552-30-7 Trimellitic Anhydride 100
SECTION 3: HEALTH HAZARD DATA
Routes of Entry:
Inhalation: Yes Skin: Yes Ingestion: Accidental
Health Hazards (Acute and Chronic): In susceptible individuals, repeated inhalation of Trimellitic Anhydride can
cause respiratory sensitization.
Carcinogenicity: NTP: Not listed
IARC Monographs: Not listed
OSHA Regulated: Not listed
Signs and Symptoms of Exposure:
INHALATION: Causes respiratory tract irritation. May cause allergic respiratory reaction. Harmful on prolonged
exposure.
EYE CONTACT: Causes severe eye irritation.
DOCUMENT NO.: 14074 805-FRM011
QA-500 Part B MSDS # MGM092A
SKIN CONTACT: Slightly irritating to the skin.
INGESTION: Causes gastrointestinal irritation and diarrhea.
Conditions Generally Aggravated by Exposure: None known.
SECTION 4: EMERGENCY AND FIRST AID PROCEDURES
INHALATION: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention immediately.
EYE CONTACT: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get
medical attention immediately.
SKIN CONTACT: Immediately wash exposed skin with soap and water. Remove contaminated clothing and
shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
INGESTION: Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. If large quantities of this material are swallowed, call a physician immediately.
NOTE TO PHYSICIAN: Acute asthmatic reactions to TMA should be treated like acute asthma from any cause.
Initial assessment should include measurement of peak expiratory flow rate (PEFR) or spirometry (FEV1). If the
PEFR or FEV1 is greater than 80% of predicted, treatment with an inhaled beta-agonist alone should be sufficient.
If the PEFR or FEV1 is less than 80% predicted or the patient does not respond to beta-agonist treatment alone,
then obtain CBC, chest X-ray, and arterial blood gases (ABGs). The primary treatment for the late respiratory
syndrome (TMA flu) is systemic corticosteroids plus antipyretics and bronchodilators as needed.
SECTION 5: FIRE AND EXPLOSION HAZARD DATA
Flash Point (Method Used): 440掳F (227掳C) Closed Cup
Flammable limits: LEL: 1% UEL: 7%
Extinguishing Media: For small fires, use dry chemical powder. For large fires, use water spray, fog, or foam. Do
not use water jet.
Special Firefighting Procedures: May be combustible at high temperature. Firefighters should wear full bunker
gear, including a positive pressure self-contained breathing apparatus.
Unusual Fire and Explosion Hazards: Fine dust clouds may form explosive mixtures with air. Handling of this
product may generate static electricity, which can present an ignition hazard in some cases. To avoid fire or
explosion, dissipate static electricity during transfer by grounding and bonding containers and equipment before
transferring material.

SECTION 6: ACCIDENTAL RELEASE MEASURES
Steps to be taken if material is released or spilled: If emergency personnel are unavailable, vacuum spilled
material. Use a vacuum equipped with a High Efficiency Particulate Aerosol (HEPA) filter. Avoid creating dusty
conditions and prevent wind dispersal. Minimize contact of spilled materials with soils to prevent run off to surface
waterways.
SECTION 7: EXPOSURE CONTROLS -- PERSONAL PROTECTION
Respiratory Protection: Use only with adequate ventilation. Avoid breathing dust. If concentration exceeds
recommended exposure levels, and ventilation is inadequate, use respirator that will protect against organic vapor
and dust/mist. If concentration is unknown, a self-contained breathing apparatus (SCBA) should be used to avoid
inhalation of the product.
Ventilation: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne
levels below recommended exposure limits. If user operations generate dust, fume, or mist, use ventilation to keep
exposure to airborne concentrations below the exposure limit.
Protective Gloves: Avoid contact with skin. Wear suitable gloves.
Eye Protection: Do not get in eyes. Wear chemical/dust goggles and faceshield.
Other Protective Clothing or Equipment: Avoid contact with skin. Wear suitable protective clothing.
Work / Hygienic Practices: Wash hands, forearms, and face thoroughly after handling compounds and before
eating, smoking, using lavatory, and at the end of the day.
SECTION 8: HANDLING AND STORAGE
Precautions to be taken in handling and storing: Keep away from heat, sparks and flame. Keep container
closed. Use only with adequate ventilation. Take precautionary measures against static discharges.
Other Precautions: Keep container in a cool, well-ventilated area. Keep container tightly closed and sealed until
ready for use. Avoid all possible sources of ignition (spark or flame).

Stability: Stable.
Conditions to Avoid: Avoid exposure to moisture or moist air. Avoid creating dust when handling and avoid all
possible sources of ignition (spark or flame).
