Ethylmagnesium bromide Specification

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. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Extremely flammable liquid and vapor. Containers may explode in the heat of a fire.
Extinguishing Media: Do NOT use carbon dioxide. Use dry chemical to fight fire. DO NOT USE WATER
Handling: Use spark-proof tools and explosion proof equipment. Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Handle under an inert atmosphere. Do not allow contact with water. Use only in a chemical fume hood.
Storage: Store in a tightly closed container. Store in a dry area. Flammables-area. Corrosives area. Water free area. Store under an inert atmosphere. Store at room temperature.
