Hazards and safety protocols for operating a 3 Tonne excavator.

safety protocols for operating a 3 Tonne excavator

Operating any type of machinery comes with hazards, and the correct safety protocols should always be taken to protect the operators. To operate a 3 Tonne excavator commercially, HSE requires drivers to produce an NPORS operators’ card prior to using the machine on a building site.

However it is worth noting that it is not a legal requirement to produce an operators licence to hire a machine like this. However, no matter the size of the excavator the same safety protocols should be adopted:

  • Wear a safety belt
  • Ensure you vision is not blocked, adjust mirrors
  • Do not use the machine to transport colleagues
  • Always survey the site before commencing digging
  • Work smoothly and avoid fast movements
  • Do not dig under other excavators
  • Always wear the required PPE
  • Avoid uneven terrain that could cause tipping hazard.
