SECTION 4 ?FIRST AID MEASURES
Inhalation: Remove victim to fresh air. If breathing is difficult, give oxygen. If not breathing,
administer artificial respiration. Get medical attention.
Skin Contact: Immediately remove contaminated clothing and shoes. Wipe excess material from
skin and flush with water for at least 15 minutes. Use soap if available or follow by
washing with soap and water. Do not reuse contaminated clothing without
laundering. Get medical attention.
Eye Contact: Immediately flush with plenty of water for at least 15 minutes. Get medical attention.
Ingestion: Get medical attention immediately.
SECTION 5 ?FIREFIGHTING MEASURES
Extinguishing Media: Use water, foam, dry chemical, or carbon dioxide (CO2)..
Special Firefighting Firefighters should wear NIOSH approved self-contained breathing apparatus.
Procedures/Precautions: Responders should wear protective clothing to prevent skin contact. Move
containers from fire area. If unable to move, cool sealed containers with water.
Unusual Fire and Toxic vapors such as oxides of carbon, aldehydes, and organic acids will be
Explosion Information: emitted upon thermal decomposition.
Environmental Note: Prevent entry into waterways.
SECTION 6 ?ACCIDENTAL RELEASE MEASURES
Protective Measures: Evacuate area of unprotected personnel. Eliminate sources of ignition. Stay
upwind and out of low areas. Wear personal protective equipment (See section 8) when responding to
spills.
Spill Management: Stop source of leak if safe to do so. Dike and contain spill. Use water spray
(fog) to reduce vapors. If vapor cloud forms, blanket area with water fog and foam. Use vacuum truck
or pump to storage/salvage vessels. Clean up residue with an absorbent such as clay, sand or other
suitable material and dispose of properly. Spray area with water to remove trace residue. Contain run-
off from residue flush and dispose of properly. Prevent entry into waterways, sewer, or confined areas.
Remove contaminated trace residues from soil and dispose of in same manner as material. For small
spills, clean up residue with an absorbent such as clay, sand or other suitable material. Place in non-
leaking container and dispose of material properly.
Disposal: Proper disposal should be evaluated based on regulatory status of this material (refer to
section 13).
SECTION 7 ?HANDLING AND STORAGE
Containers do not have to be grounded and bonded when material is transferred but is recommended as
a good practice. Store in a cool, dry place. Keep away from heat, sparks, and flames.
MAHP, Page 3 of 5
SECTION 8 ?EXPOSURE CONTROLS AND PERSONAL PROTECTION
Respiratory Protection: NIOSH approved respiratory protection for organic vapors.
Ventilation: Utilize local exhaust to control high vapor connections in confined areas.
Protective Gloves: Utilize appropriate impervious chemical gloves.
Eye Protection: Chemical goggles and possibly a face shield. Have eyewash facilities readily
available.
Other Protective Wear additional protective clothing to prevent skin contact. This may include
Equipment: chemical resistant boots and chemical resistant suits.
Work Practices: Use good personal hygiene practices. Wash hands before eating, drinking,
smoking or using toilet facilities. Promptly remove soiled clothing and wash
thoroughly before reuse. Shower after work using plenty of soap and water.
