Working with power tools

Working with power tools

In our discussion the last time, we mentioned that a power tool is any equipment that is powered by an external source, which could be electrical, hydraulic, pneumatic or powdered actuated. We will be focussing on pneumatic tools firstly. An example of a pneumatic tool is a jack hammer.

Hazards linked with using a pneumatic tool

  • Getting hit by one of the tools attachments
  • Nearby workers being struck by flying particles
  • The worker being exposed to high level noise
  • Experiencing fatigue and strains while using a jack hammer
  • Trips and falls from disconnected air hose

Prevention of injury associated with hazards from using pneumatic tools

  • Ensure to always securely fasten the air hose to the pneumatic tool
  • Ensure to always use hearing protection .e.g Ear defenders
  • Set up screens to protect nearby workers from being struck by flying particles
  • Use heavy rubber grips to reduce fatigue and strain caused by jack hammer
  • Install a safety clip so as to prevent attachments such as chisel on a chipping hammer from being ejected during operation of the tool

Let us consider a powder actuated tool. These are tools operated with the same principle as a loaded gun. Cartridges are used as source of power for powder actuated tools. They are used for fastening purposes.

Hazards associated with using Powder Actuated tool hazards

  • Ricochet of fasteners
  • Misfiring
  • Using tools on unsuitable material
  • Thorough penetration
  • Operating the tool near explosive substances

Prevention of injury associated with hazards from using Powder Actuated tools

  • Only trained worker must be allowed to use a Powder Actuated tool
  • Only appropriate powder level must be chosen to perform the work without using excessive force
  • Suitable eye , ear, and face protection must be worn while using a powder actuated tool
  • If a powder actuated tool misfires, the user must hold the tool in the operating position for at least 30 seconds before trying to fire it again
  • Never use the tool in an explosive or flammable atmosphere
  • Always inspect the tool and the barrel before using
  • Do not load the tool unless it is to be used immediately
  • Do not leave a loaded tool unattended
  • Ensure to always keep hands clear of the barrel end
  • Never point the tool at anyone
  • Avoid improper fastening that may lead to penetration, spalling, edge failure, and ricochets.
