SPILL OR LEAK

• ELIMINATE all ignition sources (no smoking,
  flares, sparks or flames in immediate area).
• All equipment used when handling the product must
  be grounded.
• Fully encapsulating, vapor protective clothing
  should be worn for spills and leaks with no fire.

GASES TOXIC FLAMMABLE (EXTREME HAZARD)
SPILL OR LEAK

• Use water spray to reduce vapors... Avoid
  allowing water runoff to contact spilled
  material.
• Do not direct water at spill or source of leak.
• If possible, turn leaking containers so that gas
  escapes rather than liquid.
• Prevent entry into waterways, sewers, basements
  or confined areas.
• Isolate area until gas has dispersed.
• Consider igniting spill or leak to eliminate
  toxic concerns.
