This is an H3
The Occupational Health and Safety Administration (OSHA) is concerned with the health and safety of workers exposed to UV radiation from the sun, black lights, welding arcs, and UV lasers. To reduce UV exposure from the sun, OSHA recommends:
- Cover up. Wear tightly-woven clothing that blocks out light. Try this test: Place your hand between a single layer of the clothing and a light source. If you can see your hand through the fabric, the garment offers little protection.
- Use sunscreen. A sun protection factor (SPF) of at least 15 blocks 93% of UV rays. You want to block both UVA and UVB rays to guard against skin cancer. Be sure to follow application directions on the bottle.
- Wear a hat. A wide brim hat (not a baseball cap) is ideal because it protects the neck, ears, eyes, forehead, nose, and scalp.
- Wear UV -absorbent shades. Sunglasses don’t have to be expensive, but they should block 99 to 100% of UVA and UVB radiation.
- Limit exposure. UV rays are most intense between 10 am and 4 pm. If you’re unsure about the sun’s intensity, take the shadow test: If your shadow is shorter than you, the sun’s rays are the day’s strongest.
