What?

Why?

Prevent fatal strikesSurveyors struck by vehicles on live roads suffer fatal or life-changing injuries. Focused instrument work reduces their awareness.
Legal complianceThe Safety at Street Works Code of Practice and Chapter 8 require protective measures for all highway workers.
Duty of careEmployers must provide safe systems of work and adequate traffic management before sending surveyors onto live carriageways.
Do Don't

  • Wear Class 3 hi-vis clothing complying with BS EN ISO 20471 at all times.

  • Position survey instruments away from live traffic lanes wherever possible.
  • Ensure Chapter 8 signing and guarding is in place before starting work.
  • Hold a valid NRSWA card if working within the public highway.
  • Plan the task to minimise time spent in or near live carriageways.
