Apply sunscreen at least 30 minutes before going out in the sun

Sunscreen

This is an H3

Staff can use sunscreen on skin that is not already covered with sun protective clothing. Sunscreens reduce the amount of dangerous UV rays that reach and damage the skin by reflecting or absorbing the radiation. Sunscreen and lip balm should have an SPF (Sun Protection Factor) of 15 or more. On average, SPF 15 provides about two hours of protection for a light-skinned person on a sunny summer day. Higher SPFs (e.g., 30 or 45) can be used for more hours of protection.

The first priority of a sunscreen and lip balm policy is to encourage use of these items. Sunscreen and lip balm usage can also be encouraged, or even required, for outdoor staff, especially on high UV days.

Sunscreen extends the skin's natural protection by a factor of the SPF number. If your skin usually burns in 10 minutes, it won't burn for 150 minutes if you are wearing sunscreen with SPF 15 (10 minutes x SPF 15 = 150 minutes or 2½ hours). Also, that SPF 15 blocks 93% of UV rays. An SPF 50 blocks only 98%. So no matter what, some UV is getting through to the skin. No sunscreen lasts all day or blocks 100% of the sun's UV radiation.

What are the sunscreen regulations the FDA established in June 2011?

The final regulations, which become effective in the summer of 2012, establish a standard test for over-the-counter sunscreen products that will determine which products are allowed to be labeled as "Broad Spectrum SPF 15 [or higher]." Products that pass this test will provide protection against both ultraviolet B radiation (UVB) and ultraviolet A radiation (UVA).  Scientific data has demonstrated that products that are "Broad Spectrum SPF 15 [or higher]" have been shown to reduce the risk of skin cancer and early skin aging when used with other sun protection measures, in addition to helping prevent sunburn. Other sun protection measures include limiting time in the sun and wearing protective clothing. In order to be labeled "Broad Spectrum SPF 15 [or higher], a sunscreen will have to screen a significant portion of UVA spectrum (up to at least 370 nanometers). Also, the amount of UVA protection must increase as the SPF value increases. In contrast, any sunscreen not labeled as "Broad Spectrum SPF 15 [or higher]" or that has an SPF value between 2 and 14, can only claim to help prevent sunburn.

Beginning in 2012, manufacturers cannot make claims that sunscreens are "waterproof" or "sweatproof, or identify their products as "sunblocks," because no sunscreen blocks 100% of UV.  Also, sunscreens cannot claim protection immediately upon application (for example, "instant protection") or protection for more than two hours without reapplication without submitting data to support these claims and obtaining FDA approval.

In additional proposed rules, the FDA is further proposing that an upper limit for SPF values be set at 50+. This is because there is not sufficient data to show that products with SPF values higher than 50 provide greater protection for users than products with SPF values of 50.
