What is the minimum fire extinguisher rating required within 30 feet for a Torch-applied Roof System?

The minimum fire extinguisher rating required within 30 feet for a torch-applied roof system is a 3-A:40-B:C rating. This rating is important for ensuring proper fire safety measures when using equipment that poses a higher risk of ignition due to the use of open flames or intense heat.

A rating of 3-A indicates the extinguisher's effectiveness against ordinary combustibles such as wood and paper, while the 40-B component pertains to its effectiveness against flammable liquids. The C signifies that the extinguisher is suitable for electrical fires, making it versatile and applicable in various situations that might arise on a construction site where a torch-applied roofing method is being utilized.

Understanding this rating is crucial for compliance with safety standards and ensuring that personnel working on or around such installations have readily available and appropriate fire-fighting tools to mitigate hazards.
