Employers and outdoor workers urged to reduce skin cancer risk by prioritising sun safety

Wednesday 21st May 2025

As the warmer months approach, the Health and Safety Authority (HSA) is today, Wednesday 21st May, reinforcing the importance of sun protection for outdoor workers, even when skies are overcast.

Under health and safety legislation, employers have a duty to manage the risks associated with sun exposure and implement measures to protect against this natural source of UV radiation.  

Skin cancer is the most common form of cancer in Ireland and the number of people being diagnosed with skin cancer is rising. In response, the HSA is encouraging employers, the self-employed and employees to take practical, preventative steps to reduce the risks of sun exposure.

Many jobs, including those in construction, agriculture, horticulture, couriers/postal workers, waste collection and fisheries, involve prolonged outdoor activity, increasing exposure to ultraviolet (UV) radiation and the associated risks of skin cancer, eye damage and heat-related illnesses.

Helen Hourihane, Senior Inspector with the HSA, emphasised, 

“Even on overcast days, ultraviolet radiation can still be at levels that pose a real risk to anyone working outside for long periods.  It's a common misconception that cloud cover offers full protection - this simply isn’t the case.  When the UV Index is 3 or above, protective measures are needed when working outdoors. In Ireland this is typically between 11am to 3pm, April-September.” 

Protective Measures

The HSA, in partnership with the HSE National Cancer Control Programme (NCCP), provide tools and resources for employers and employees, and recommends the following measures for sun protection:

• Evaluate UV Exposure Risks: Review outdoor work routines and environments to identify where workers are at risk.
• Plan the Work: Where feasible, arrange outdoor duties to reduce the time and intensity of exposure to direct sunlight when the UV is strongest.
• Provide Shade: Seek and provide shade where possible, and ensure break areas are provided in shaded or covered locations.
• Protect Skin: Wear suitable clothing such as long-sleeves, wide-brimmed hats, neck-flaps and sunglasses. 
• Supply Sunscreen: Make SPF 30+, broad-spectrum sunscreen available and promote its regular use.
• Training and Awareness: Give workers information on the dangers of UV exposure and how to protect themselves. Advise them to self-check skin for any changes and unusual moles or spots.

Tips for Employees

Employees are also advised to take proactive steps for their personal protection:

• Dress for the Sun: Wear clothing and accessories that shield the skin and eyes from harmful rays.
• Apply Sunscreen Regularly: Use SPF 30+ sunscreen at least 20 minutes before outdoor activity and reapply often, especially after sweating.
• Stay in the Shade When Possible: Use natural or provided shelter during rest periods.
• Drink Plenty of Water: Keep hydrated throughout the day to prevent heat stress.

Maria McEnery, Cancer Prevention Officer, HSE National Cancer Control Programme (NCCP), added, 

“Skin cancer is the most common form of cancer in Ireland and is largely preventable by protecting skin with clothing, shade and sunscreen. We strongly encourage all outdoor workers to utilise the extensive guidance, tools and awareness materials to help protect themselves and safeguard their health.”
