Study Notes

Cellulose Insulation

Composed of finely ground, recycled newspaper enhanced with fire-resistant chemical additives.
Typically installed by mechanically blowing into empty spaces within structures to provide thermal insulation.

Overhaul

A fire-fighting process aimed at identifying and eliminating hidden fire hazards after a fire has been suppressed.
Involves assessing whether the main fire has been fully extinguished to prevent subsequent fires.
Main objective is to mitigate the chances of rekindle, which is a return of fire due to residual embers or other ignition sources.

Rekindle

Refers to the emergence of a new fire in an area where a fire was previously extinguished.
Not indicative of a complete failure in extinguishment; it can happen despite thorough overhaul efforts.
Overhaul activities significantly lower the risk of rekindling by ensuring all hot spots are checked and addressed.

Effective Overhaul Practices

Safety is a priority during overhaul, requiring adherence to Standard Operating Procedures (SOPs) related to fireground exposure and using self-contained breathing apparatus.
Use of thermal imaging cameras and foam applicators is critical in identifying hidden heat sources.
Continuous positive pressure ventilation should be employed to maintain a safe working environment and help reduce losses.
Fire companies must actively assess conditions while using ventilation fans.
Engaging with property owners or occupants is vital to discuss overhaul measures and any concerns.
Conducting post-incident inspections, including drive-bys or walk-throughs, ensures no potential ignition sources remain.
Coordination with fire investigators is necessary to support safety and investigative measures during overhaul operations.
