The UV index is usually listed as a number. The numbers are grouped into low, medium, and high. Knowing the UV index will allow you to prepare for the level of protection needed, as well as better plan daily tasks, mainly between 10 am and 4 pm, when the sun is at its strongest. Try to minimize outdoor work during the middle of the day and maximize the time during the early part of the day when UV levels are lowest. If the UV index is 3 or above, you need to protect your skin. Another easy way to measure the sun’s strength is to look at your shadow. During the early morning or late afternoon, if your shadow is taller than you are, the UV exposure is likely to be lower. Then, around noon, if your shadow is shorter than you are, UV exposure is likely to be higher.
Reduce Sun Exposure
- Plan outdoor work in the early mornings and afternoons
- Organize work tasks to limit exposure to the sun
- Provide shade when possible
- Encourage employees to take breaks under the shade
Whenever possible, try to schedule outdoor work for the early mornings and late afternoons, when the sun is less intense. Even during the morning and afternoon, try to rotate your crew, ensuring that the amount of time that each person is exposed to the sun is minimized. For stationary work, provide a tent or cover – it should be made of a material that is fire rated and tested for UV protection of 30+.
