Storage and Handling

  • cannot be avoided. Where eye contact is a potential hazard, goggles or face shields should be worn.
  • Ambient temperatures and atmospheric pressures normally encountered within buildings or roofed-over outdoor storage areas are acceptable.
  • Avoid entering areas where mists or vapours have built up as a result of abnormal temperatures or pressures without the proper breathing equipment and protective clothing.
