  2. Heat Guns • Aheatgunisconstructedwith a motor-driven fan thatdraws in air and passes it over a heating coil that easily becomes red-hot. • Heat guns are frequently used in research labs to dry glassware, heat the upper parts of a distillation apparatus during distillation of high-boiling point materials, and to develop thin-layer chromatography (TLC) plates. • Other heat gun applications for removing or softening materials also exist in the lab setting.

  3. Heat Gun Hazards: • The heating element in a heat gun typically becomes extremely hot during use; however, the lack of a visible flame can create a false sense of security or false impression of safety and while the danger zone is invisible, it is very active. The combination of sparks and forced ventilation over a glowing filament may lead to fire and/or explosion. • Heat guns operate at lower air speeds and produce temperature as high as650℃, hot enough to melt some types of glass. .

  4. Keep the following in mind when using a heat gun: • Wear appropriate personal protective equipment (PPE) when using a heat gun. A flame retardant lab coat and safety glasses should be considered the minimal requirement. • Do not use a heat gun near combustible or flammable materials including open containers of flammable liquids, flammable vapors or hoods used to control flammable vapors/atmospheres.

  5. Keep the following in mind when using a heat gun: • Be aware of the direction of the heat. Never direct the air flow towards one’s body. • Always switch the heat gun off before putting it down on any surface. • Always maintain a minimum of one centimeter of clearance between outlet nozzle and work surface.

  6. Keep the following in mind when using a heat gun: • Never touch the hot metal nozzle with clothing or skin. • Do not look down the nozzle while the gun is turned on. • Do not insert anything down the nozzle of the gun. • Allow the tool to cool before storing it. HOT

  7. Keep the following in mind when using a heat gun: • Do not use an extension cord to power a heat gun because a high current draw can result in overheating and pose risk of fire or electrocution. • Unplug the heat gun when not in use, especially if the lab is unoccupied. • Never hold a sample without forceps while using a heat gun or you will risk direct exposure of the heat to your hand.
