1-PENTANETHIOL Specification

1、Fire Fighting Measures of 1-PENTANETHIOL
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors can travel to a source of ignition and flash back. Will burn if involved in a fire. Flammable liquid and vapor. Containers may explode if exposed to fire.
Extinguishing Media: Use water spray to cool fire-exposed containers. Use foam, dry chemical, or carbon dioxide.
2、Handling and Storage of 1-PENTANETHIOL
Handling: Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. This product may be under pressure; cool before opening. Storage: Keep away from sources of ignition. Store in a cool, dry place. Keep container closed when not in use. Flammables-area. Store under nitrogen.
