Common hazards (high level)
  • TOXIC; may be fatal if inhaled, ingested or absorbed through skin.
  • Inhalation or contact with some of these materials will irritate or burn skin and eyes.
  • Methyl chloroacetate (UN2295) is an eye irritant/lachrymator (causes flow of tears).
  • Fire will produce irritating, corrosive and/or toxic gases.
  • Vapors may cause dizziness or asphyxiation, especially when in closed or confined areas.
  • Runoff from fire control or dilution water may cause environmental contamination.
  • HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
  • Vapors may form explosive mixtures with air.
First actions (field-minded)
  • CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
  • Keep unauthorized personnel away.
  • Stay upwind, uphill and/or upstream.
  • Ventilate closed spaces before entering, but only if properly trained and equipped.
  • Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
  • For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
  • For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
