Power Tool Safety

Power tools are the equipment that propels over 8 million construction workers on a daily basis. With thousands of tools available, these pieces of equipment make our jobs easier, but when used incorrectly can become hazardous in an instant. Below we will review the safety features of power tools and the hazards you need to be aware of when working with them.
 
Safety Features
Most power tools have new safety features to reduce the risk of injuries. Depending on the type of power tool, you may need to make sure each feature is available and in working condition. Let’s review some common safety features of power tools and what OSHA recommends:

• Guards – all exposed moving parts of tools must be guarded to protect from rotating parts, sparks, flying chips, and pinch points. Commonly used in circular saws and grinders, OSHA requires a machine guard at all times for blades/discs greater than 2 inches
• Pressure Switches and Shutoffs – switches that shut off power when released. OSHA requires most hand-held tools to have pressure switches including drills, drivers, grinders, sanders, and saws. Larger tools such as disc sanders, routers, and planers are required to have a control switch or pressure switch to shut off power
• Accessory Safety Clips – locks or mechanisms that keep tool accessories from being ejected during operation. Commonly used with saw blades, chisels, and drill bits, OSHA requires all clips to be in working condition prior to use

 
Power Tool Hazards
Even though power tools are used on a regular basis, employers are still required to provide training and hazard recognition for power tools that employees will use. Below we will review the three common types of power tools and the most common hazards associated with them:

Electrical​

• Shocks and burns – caused when the electrical current is disrupted and flows incorrectly through the body. To prevent, electrical tools should have a three-wire cord and be grounded through the receptacle. Additional best practices include inspecting cords for worn or frayed insulation and to not use in wet or damp locations unless rated properly
  

​
Battery Operated

• Fires – occur when the battery or tool are overworked or used incorrectly. Best practices include using compatible batteries with select tools, inspecting to make sure batteries have no damage or leaks, and store batteries in a dry area off charging stations

Pneumatic

• Misfires or explosions – caused when the compressed air is improperly traveling through the hose. To prevent, locking attachments for tools and additional safety valves to gauge pressure flow should be installed on hoses 
  

Power tools help us build efficiently and reduce strains on workers. Making sure you select proper power tools and use their safety features to reduce hazards will help keep all employees safe on the job. To keep the conversation going, download the Power Tools Toolbox Talk (TBT) or comment below.
