Hazard Index Tables
The required level of Building By-law upgrade for Change of Use and Change of Major Occupancy Type projects is dependent on whether or not the Hazard Index has increased for the proposed alteration.
Hazard Index ratings are intended to reflect the level of fire and life safety risk to occupants for various building uses. Hazard index ratings range from 1 to 6, such that a hazard index of rating of 6 represents the highest risk to occupants.
The hazard index for various building uses are indicated below.
