4.1 Description of first aid measures
Eye Contact: Immediately flush eyes with plenty of water for 15 to 20 minutes. Get medical attention, if irritation or symptoms of overexposure persists.
Skin Contact: Immediately wash skin with plenty of soap and water for 15 to 20 minutes, while removing contaminated clothing and shoes. Get medical attention if irritation develops or persists.
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration or give oxygen by trained personnel. Seek immediate medical attention.
Ingestion: If swallowed, do NOT induce vomiting. Call a physician or poison control center immediately. Never give anything by mouth to an unconscious person.
4.2. Most important symptoms and effects, both acute and delayed
4.3 Indication of any immediate medical attention and special treatment needed
No additional information.
5.1 Extinguishing media
Extinguishing Media: Use alcohol resistant foam, carbon dioxide, dry chemical, or water fog or spray when fighting fires involving this material.
Unsuitable Media: None.
5.2 Special hazards arising from the substance or mixture
Hazardous Combustion Byproducts: Oxides of carbon, aldehydes, amines, aniline, acids and other organic substances may be formed during combustion. The chemical nature and quantity of decomposition by-products will vary widely depending on the conditions of combustion.
Unusual Fire Hazards: Sealed containers at elevated temperatures may rupture explosively and spread fire due to polymerization.
5.3 Advice for firefighters
Fire Fighting Instructions: Evacuate area of unprotected personnel. Use cold water spray to cool fire exposed containers to minimize risk of rupture. Do not enter confined fire space without full protective gear. If possible, contain fire run-off water.
Protective Equipment: As in any fire, wear Self-Contained Breathing Apparatus (SCBA), MSHA/NIOSH (approved or equivalent) and full protective gear.
NFPA Health: 3
NFPA Fire: 1
NFPA Reactivity: 1
6.1 Personal precautions, protective equipment and emergency procedures
Personnel Precautions: Evacuate area and keep unnecessary and unprotected personnel from entering the spill area. Use proper personal protective equipment as listed in Section 8.
6.2 Environmental precautions
Environmental Precautions: Avoid runoff into storm sewers, ditches, and waterways.
6.3 Methods and material for containment and cleaning up
Methods for Containment: For small spills, activate available exhaust ventilation equipment in the immediate spill area. Wipe up or absorb spilled material with paper towels or other absorbent material. For large spills, dike area to contain spill. Take precautions as necessary to prevent contamination of ground and surface waters.
Methods for Cleanup: For small spills, wash area with soapy water to remove residue. Collect absorbed material and water rinses in appropriate containers. Dispose of in accordance with Federal, State and local regulations. For large spills, recover spilled material on adsorbent, such as sawdust or vermiculite, and sweep into closed containers for disposal. After all visible traces, including ignitible vapors, have been removed thoroughly wet vacuum the area. If area of spill is porous, remove as much contaminated earth and gravel, etc. as necessary and place in closed containers for disposal. Do not flush to sewer.
Other Spill Precautions: Spill response operations must be conducted in accordance with the provisions of OSHA 29 CFR 1910.120. Review the entire SDS before proceeding with spill response.
6.4 Reference to other sections
Use proper personal protective equipment as listed in Section 8.
7.1 Precautions for safe handling
Handling: Use with adequate ventilation. Avoid breathing vapor, aerosol or mist. Avoid contact with eyes, skin, or clothing. Avoid prolonged or repeated contact with skin. Keep container tightly closed when not in use.
Special Handling: Provide appropriate ventilation/respiratory protection against decomposition products (see Section 10) during welding/flame cutting operations and to protect against dust during sanding/grinding of cured product.
Hygiene Practices: Use good personal hygiene practices. Wash hands before eating, drinking, smoking or using restroom facilities. Promptly remove contaminated clothing and launder thoroughly before reuse.
7.2 Conditions for safe storage, including any incompatibilities
Storage: Store in a cool, dry, well ventilated area away from sources of heat and incompatible materials. Keep container tightly closed when not in use. Do not reuse empty containers. Keep out of the reach of children.
7.3. Specific end use(s)
No additional information.
8.1 Control parameters
Exposure Guidelines
ACGIH: Skin:Skin
8.2 Exposure controls
Appropriate engineering controls
Engineering Controls: Use appropriate engineering control such as process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits. Good general ventilation should be sufficient to control airborne levels. Where such systems are not effective wear suitable personal protective equipment, which performs satisfactorily and meets OSHA or other recognized standards. Consult with local procedures for selection, training, inspection and maintenance of the personal protective equipment.
Individual protection measures
Eye Protection: Wear appropriate protective glasses or splash goggles as described by 29 CFR 1910.133, OSHA eye and face protection regulation, or the European standard EN 166.
Skin Protection: Chemical-resistant gloves and chemical goggles, face-shield and synthetic apron or coveralls should be used to prevent contact with eyes, skin or clothing.
Respiratory Protection: A NIOSH approved air-purifying respirator with an organic vapor cartridge or canister may be permissible under certain circumstances where airborne concentrations are expected to exceed exposure limits. Protection provided by air purifying respirators is limited. Use a positive pressure air supplied respirator if there is any potential for an uncontrolled release, exposure levels are not known, or any other circumstances where air purifying respirators may not provide adequate protection. A respiratory protection program that meets OSHA 1910.134 and ANSI Z88.2 requirements must be followed whenever workplace conditions warrant the use of respirators.
Other Protective: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
Hygiene Practices: Use good personal hygiene practices. Wash hands before eating, drinking, smoking or using restroom facilities. Promptly remove contaminated clothing and launder thoroughly before reuse.
