    Study Notes

    Guidelines for Incidents Involving Cellulose Insulation

    • Cellulose insulation has significant rekindle capability and undergoes a fire-retardant treatment, but its capability diminishes over time due to natural decay.
    • Characteristics of cellulose insulation include fibre texture, manilla/tan/brown colour, light weight, and usually found resting on top of other attic insulations.
    • The rekindle risk at a fire involving cellulose insulation is high, and personnel should never assume fires are extinguished.

    Precautions and Procedures

    • Incident Commanders must establish fire origin and extent of spread, and ensure complete extinguishment using various methods, including thermal imaging cameras and visual observation.
    • Overhaul procedures should include complete removal of cellulose insulation from a reasonable size area beyond the fire area (minimum 3m radius) whenever possible.
    • Removed cellulose insulation should be placed in garbage bags or tarps and removed to the outside of the structure, then thoroughly wet and protected from wind/air movement.
    • SCBA must be worn during removal and handling of cellulose insulation.
    • Incident Commanders should establish at minimum gross decontamination of all personnel and equipment involved in the removal of cellulose insulation.

    Fire Watch and Aftermath

    • A fire watch implemented by the Platoon Chief should not be terminated earlier than 24 hours from its implementation.
    • The Incident Commander should advise the property owner or responsible person of the potential rekindle risk associated with cellulose fibre insulation, regardless of apparent extinguishment.
    • The Incident Commander should direct the property owner or responsible person to ensure that required and installed detection devices are functioning.
    • Relevant information should be recorded in the memo books and added to the Officer's Narrative of the Emergency Incident Report.

    Important Reminders

    • Incident Commanders should exercise reasonable discretion and consider the safety of the public and Toronto Fire Services personnel in their decisions.
    • The guideline may not address all circumstances, and decisions should be made based on the specific situation.
