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.
