Storage & Handling

Handling Recommendations
  • Keep containers closed when not in use.
  • Open containers slowly to allow any excess pressure to vent.
  • Keep away from heat, sparks, flame, or other sources of ignition.
  • Protect small containers from physical damage.
  • Use proper electrical grounding and bonding procedures when loading, unloading, and transferring.
  • Use spark-resistant tools.
  • Electrical equipment and circuits in all storage and handling areas must conform to requirements of national electrical code (Articles 500 and 501) for hazardous location.
