Near Ultraviolet (includes Sun Safety)

Near Ultraviolet Safety

Near ultraviolet refers to any ultraviolet (UV) light in the 180 to 400 nanometer wavelength region of the electromagnetic spectrum. The purpose of the UV safety program is to ensure the members of the Brown community avoid adverse effects from overexposure to UV radiation. UV radiation is divided into three distinct bands UV-A, UV-B and UV-C. Each has different penetration properties and potential for damage. The laboratory supervisor (i.e.principal investigator) should decide what measures are necessary to limit access to the UV source and to make personnel aware of its presence. It may be necessary to limit exposure time, install a caution sign or a visual indicator. After these steps have been taken, it should be determined whether it is necessary to provide protection for the face, eyes or skin, and what type of personal protective equipment (PPE) is needed. PPE may consist of gloves, laboratory coat, UV protecting eyewear and/or face shield.

If your lab has an active UV source, the laboratory Chemical Hygiene Plan & Laboratory Safety Manual, Section 3 will contain a standard operating procedure outlining the PPE to be donned while using a UV source.

Sun Smart Safety

The Sun Smart safety program is intended to educate the Brown Community about the adverse effects of overexposure to sunshine.

Ultraviolet radiation is the foremost radiation safety hazard to faculty, staff and students at Brown University. Over the past three decades, more people in the United States have had skin cancer than all other cancers combined. The following simple steps can be taken to safeguard your skin from the harmful effects of UV radiation from the sun:

  • Wear proper clothing (including a brim hat and sunglasses);
  • Avoid getting sunburned;
  • Go for the shade;
  • Use extra caution when near reflective surfaces, such as water, snow and sand;
  • Use extra caution when at higher altitudes;
  • Apply broad-spectrum sunscreen;
  • Re-apply broad-spectrum sunscreen throughout the day.
