Specification
1. Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.Keep away from heat, sparks, and flame. Keep away from sources of ignition. Keep container closed when not in use.
2. Handling: Avoid ingestion and inhalation. Avoid contact with eyes, skin, and clothing. Avoid contact with heat, sparks and flame. Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Use with adequate ventilation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
3. Personal Protection: 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 gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
4. Fire Fighting: Wear a self-contained breathing apparatus in pressure-demand, SHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Combustible Liquid. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Use water spray to cool fire-exposed containers. Use agent most appropriate to extinguish fire.
