Reacts with water.soluble in ether and tetrahydrofuran; insoluble in hydrocarbons

water-free area

Prone to spontaneous combustion when there is no ether immersion; ether is flammable

EXPLOSION RISK.

Moisture sensitive|... May react violently with water. /Methyl magnesium bromide in ethyl ether/

Highly flammable. The solution reacts with water or moisture in the air to form flammable methane gas. The heat from this reaction may be sufficient to ignite the produced methane. Unstable peroxides may form with exposure of the ether to air. This is a slow process.

Ethers

Highly Flammable

Organometallics, such as METHYL MAGNESIUM BROMIDE, are reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases.

Excerpt from ERG Guide 135 [Substances - Spontaneously Combustible]: Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated. (ERG, 2016)

Excerpt from ERG Guide 135 [Substances - Spontaneously Combustible]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above. FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Excerpt from ERG Guide 135 [Substances - Spontaneously Combustible]: Fully encapsulating, vapor-protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch or walk through spilled material. Stop leak if you can do it without risk. SMALL SPILL: EXCEPTION: For spills of Xanthates, UN3342 and for Dithionite (Hydrosulfite/Hydrosulphite), UN1384, UN1923 and UN1929, dissolve in 5 parts water and collect for proper disposal. CAUTION: UN3342 when flooded with water will continue to evolve flammable Carbon disulfide/Carbon disulphide vapors. Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. Use clean, non-sparking tools to collect material and place it into loosely covered plastic containers for later disposal. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2016)

Excerpt from ERG Guide 135 [Substances - Spontaneously Combustible]: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing will only provide limited protection. (ERG, 2016)|Personnel protection: ...

If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use "alcohol" foam, dry chemical or carbon dioxide. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Do not use water on material itself. /Methyl magnesium bromide in ethyl ether/|Evacuation: If fire becomes uncontrollable or container is exposed to direct flame - consider evacuation of one-third (1/3) mile radius. /Methyl magnesium bromide in ethyl ether/

The solution /methyl magnesium bromide in ethyl ether/ reacts with water to give methane, a flammable gas. The heat of this reaction may be sufficient to ignite the methane. /Methyl magnesium bromide in ethyl ether/

If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Build dikes to contain flow as necessary. Use water spray to knock-down vapors. Do not use water on material itself. /Methyl magnesium bromide in ethyl ether/|Personnel protection: Avoid breathing vapors. Keep upwind. ... Do not handle broken packages unless wearing appropriate personal protective equipment.

Excerpt from ERG Guide 135 [Substances - Spontaneously Combustible]: Fire will produce irritating, corrosive and/or toxic gases. Inhalation of decomposition products may cause severe injury or death. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution. (ERG, 2016)

Excerpt from ERG Guide 135 [Substances - Spontaneously Combustible]: Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Keep victim calm and warm.
