A dangerous fire and explosion risk; [Hawley] Apart from their instability in air and their caustic basic properties, organomagnesium compounds and the precipitated inorganic magnesium salts produced during their use display no pronounced toxicity or side effects of environmental concern. [Ullmann] Reacts violently with water producing highly flammable gases; May form explosive peroxides; A corrosive substance that can cause injury to the skin, eyes, and respiratory tract; Inhalation may cause chemical pneumonitis; [MSDSonline]

/GUIDE 138: SUBSTANCES - WATER-REACTIVE (EMITTING FLAMMABLE GASES)/ Fire or Explosion: Produce flammable gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Runoff may create fire or explosion hazard. /Organometallic substance, liquid, water-reactive, flammable/

/GUIDE 138: SUBSTANCES - WATER-REACTIVE (EMITTING FLAMMABLE GASES)/ Health: Inhalation or contact with vapors, substance, or decomposition products may cause severe injury or death. May produce corrosive solutions on contact with water. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution. /Organometallic substance, liquid, water-reactive, flammable/

/GUIDE 138: SUBSTANCES - WATER-REACTIVE (EMITTING FLAMMABLE GASES)/ Public Safety: CALL Emergency Response Telephone Number ... . 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 meter (75 feet) for solids. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate the area before entry. /Organometallic substance, liquid, water-reactive, flammable/

/GUIDE 138: SUBSTANCES - WATER-REACTIVE (EMITTING FLAMMABLE GASES)/ Protective Clothing: 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 in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible. /Organometallic substance, liquid, water-reactive, flammable/
