Features

• Some staple guns offer more features than others. According to the sources at Packaging and Fastening, some staple guns offered by Bostitch feature a "Contact Trip" which prevents accidental discharge when the trigger is pulled. "Sequential Trips" prevent accidental discharge when a staple gun gets bumped or dropped.
  
  

Work Area

• It is important to keep the general work area clean while operating a staple gun, and work areas should maintain adequate lighting while staple guns are in use, according to Rowley Company. Accidents are more likely to happen in cluttered, poorly lit work environments. Sparks from power staple guns can cause a fire; staple guns should be operated with caution near flammable substances.
  
  

Personal Safety

• According to Packaging and Fastening, staple guns should never be held or carried with a finger on the trigger. Correct finger placement helps reduce the risk of an accidental firing. According to Rowley Company, safety glasses as well as ear plugs should be employed while operating staple guns. Staple gun operators should maintain secure footing and keep a firm grasp on the staple gun while operating it. These devices should never be operated if the user is fatigued.
  
  

Operational Safety

• Staple gun operators should use clamps or other devices to secure work pieces before working on them with staple guns. People should never attempt to operate a staple gun if the device is working improperly. Staples should only be applied to appropriate surfaces and never fired at too steep of an angle. Perhaps the most important safety measure linked with staple guns is to never point one at another person.
  
  

Electrical

• Staple guns should be disconnected from their power source after use. Staple guns should not be exposed to wet conditions because of the risk of electrical shock. If a staple gun is connected to a power cord, the device should never be carried by the cord. Staple guns and power cords need to remain away from excessive heat.
