Toolbox Talk - UV Radiation

Max People Health & Safety Bulletin

Most skin cancers are caused by excess exposure to ultraviolet (UV) radiation from the sun. In New Zealand, UV radiation levels are particularly high from September to April. It is important to be Sun Smart during these times.

The sun sends out different types of radiation:

  • Sunlight (that you can see and feel as heat)
  • Infrared radiation (that you can feel as heat)
  • UV radiation (that you cannot see or feel).

You need to be careful when it’s cool (and/or cloudy) outside from September to April.

When it’s cool it means there’s less infrared radiation but not necessarily less UV radiation. You can still get sunburn on cool and cloudy days.

Checking for skin cancer

It is important you check yourself regularly for any moles or skin patches that have appeared or changed over time. See your doctor as soon as possible if you:

  • See or feel something that's new on your skin
  • See or feel something that’s different from other moles
  • Notice a mole that’s changed from the last time you checked - this could include a change in the colour, shape or size, or if it is bleeding or itchy.
