Sun Protection Factor (SPF) measures sunscreen protection from UVB rays − the rays that cause sunburn and contributes to skin cancer. Typically, you can multiply the SPF number by ten to know how many minutes you can stay in the sun without burning. It’s important for Chandos employees to be aware of the dangers that come with working in the sun and the personal safety precautions they can employ themselves.
Sunlight doesn’t only do direct damage; light reflected off of bodies of water and, related to our construction sites, concrete can also cause UV exposure.
Weather reports include a UV index, which can provide you with some clues on how to prepare for your work day:
- When the index is high (7 or higher), you can get sunburned in only 15 to 20 minutes.
- The highest exposure of the day is from noon to 2 pm.
To limit the damaging effects of the sun on site:
- Wear a shirt and long pants to cover most of your skin.
- Protect the rest of your skin with sunscreen (the more you sweat, the more often you need to reapply sunscreen).
- Protect your eyes. Wear safety sunglasses if the tint doesn’t interfere with your vision (most safety glasses—clear or tinted—decrease your UV exposure).
- Wear a lip chap with SPF to prevent the sensitive skin on your lips from burning.
- Reapply sunscreen if you start to feel yourself burning.
