OS1 Fire Safety



Intent 1:

To limit the probability that inappropriate design, construction or installation will lead to performance that is significantly below expectations, which could lead to:

  • the accumulation of vapours or residues in hazardous concentrations or quantities which could be ignited in the presence of an ignition source,
  • the ignition of nearby combustible materials as a result of the use and operation of cooking equipment and its ventilation system, or
  • the spread of fire involving cooking equipment or its ventilating system.

This is to limit the probability of fire or explosion, which could lead to harm to persons.

Intent 2:

To direct code users to Article to determine the fire-resistance rating for factory-built and field-applied grease duct enclosures assemblies.
