3 Safety Tips for Using a Heat Gun

It’s handy to own a heat gun because it’s a very useful tool when redecorating. However, a heat gun is dangerous and at full power, it can operate at about 1200 degrees Fahrenheit. This can easily burn you so it’s vital that you know how to use your heat gun safely and how to avoid starting any fires.

Safety Wear

When you use a heat gun, you need to wear safety goggles to protect your eyes. Also wear a respirator mask to avoid inhaling fumes coming off the paint. Wear gloves that are resistant to chemicals as you’ll also be scraping paint and this will keep the chemicals off your skin.

If you have long hair, keep it tied back or under a hat so it can’t accidentally be set on fire by the heat gun. If you’re wearing a long-sleeved shirt, make sure the cuffs are buttoned so they can’t flap around in front on the heat gun.


If you’re using a heat gun inside, make sure that the area is well ventilated to prevent the accumulation of fumes. It’s best if you can work outside where there’s no danger on inhaling toxic fumes. Where there’s no option but to work in a confined area, always wear a respirator mask.

Safety When Using a Heat Gun

Part of keeping yourself safe when using a heat gun is using it properly and, more importantly, knowing when not to use it. For example, you should never use a heat gun on lead-based paint since it can release toxic fumes. Don’t ever keep the heat gun pointed at a single spot for more than a few seconds. This can cause scorching of the wood. Instead, use a slow circular movement.

Make sure there is no debris, such as wood shavings or sawdust on the surface you’re working on. The heat from the heat gun could set it afire. Just in case, you should always keep a fire extinguisher handy when you work with a heat gun. When you plug in a heat gun, always use an outlet that’s grounded. This can prevent it from shorting out and stop any possibility of an electrical fire.

Be very careful when you use a heat gun around material that’s been soldered. The heat can melt the solder and you could end up with leaking pipes or an item that no longer has strength. Always use the heat setting recommended by the manufacturer rather than what you think is apt. This prevents you from overheating a surface.

Be careful where you aim the heat gun as you work. It’s very easy to end up with it pointing at yourself without realizing it. Even heat penetrating through clothing can burn you. When you’ve finished using the heat gun, place it on a heatproof mat or similar surface until cool because the element inside will still be extremely hot.

Make sure children stay well clear of the area where you’re working. Because of the fumes, women who are pregnant or nursing should also stay clear of the area.
