Safe Use of Temporary Heating Equipment

Welcome back, let's Build Smart & Build Safe! We’ve covered the risks of cold stress and the silent danger of Carbon Monoxide (CO). Today, we focus on the procedures that allow us to use Temporary Heating Equipment safely, minimizing fire and CO risks.

The heater's primary job is warmth, but our primary job is safety.

Safe Clearances and Fire Prevention

Temporary fuel-burning heaters pose a significant fire risk due to the high temperatures they generate.

1. Maintain Clearance: Heaters must be kept a safe distance (usually 10 feet) away from all combustible materials—including walls, plastic sheeting, canvas tarps, wood, insulation, and fuel containers. Check the manufacturer’s instructions for the specific required clearance.

2. Stable, Level Surface: Place heaters on a level, non-combustible surface to prevent tipping. Heaters must be protected from accidental contact or being knocked over by site traffic. Many units have a tilt sensor that shuts them off if knocked, but you shouldn't rely on it.

3. Fire Extinguisher Ready: Due to the increased risk of fire in the immediate area, a rated fire extinguisher (usually ABC dry chemical) must be readily accessible near the heating unit.

Fuel Handling and Storage

Improper storage and refueling are major causes of site fires and explosions.

• Refuel Outside: Never refuel a heater indoors or in an unventilated area. Residual fuel vapors can ignite easily. Allow the unit to cool completely before adding fuel.

• Outdoor Storage: Store liquid fuel (like kerosene) and propane tanks outside of the building or work enclosure. Fuel storage areas must be designated, secured, and clearly signed. Keep the minimum amount of fuel necessary for a day's work on site.

• Propane Tank Management: Keep propane tanks upright to prevent liquid discharge and protect the tank valves from damage.

Using temporary heat is a trade-off. We accept the CO and fire risks only if we implement strict, constant control measures.

Tomorrow, we'll discuss safe driving and equipment operation under winter conditions.
