Description of key information

>=500°C based on the Discussion.

Key value for chemical safety assessment

Additional information

Since the substance is made at ~97% of the following three constituents, it can be deduced that its Auto-ignition temperature is >=500°C:

  • Carbon monoxide: >= 630°C, see study summary
  • Hydrogen: >= 500°C, see study summary
  • Nitrogen: none, this non-flammable gas is routinely used to inert flammable gases so it decreases the flammability of the gas mix
