Say this

  1. The occupier must provide enough suitable lighting wherever people work or walk (WSH (General Provisions) Regulations). If a work area, stair or walkway is dark, stop and tell me.
  2. Check the lights before you start. Point lights so they do not dazzle drivers or crane operators.
  3. Wear your high-visibility vest all shift. Drivers see you much later at night.
  4. Your body is at its lowest between 2am and 6am. WSH Council advises keeping critical work out of that window where possible (WSH Council fatigue guidelines).
  5. Take your rest breaks. A short nap of 20 to 30 minutes helps. Give yourself time to wake up properly before safety-critical work.
  6. Watch your buddy. Heavy eyelids, slow answers and missed steps are warning signs.
  7. If you feel too tired to work safely, say so. We will move you to other work.

Ask the crew

  1. What do you do if your work area is not lit well enough?
  2. When are you most likely to feel tired on a night shift?
  3. How long should a power nap be?
  4. What signs show that a workmate is too tired?

Show them

  • The lighting towers and portable lights, and who to call if one fails.
  • Dark spots we found on last night's walk round.
  • The rest area for night shift breaks.
