“…When a fabric gets wet, light scattering is reduced, which leads to an increase of UV penetration. (6) For most gloves, there was no significant change in transmittance due to 24-hr saline treatment (Table IV). However, there were small, statistically significant differences in UVA transmittance for Perry and Safeskin gloves.…”

The transmission of ultraviolet radiation (UVR) from an ultraviolet transilluminator through three types of laboratory gloves (latex, nitrile, vinyl) was determined using two independent methods. First, transmittance was measured with a radiometer equipped with UVA and actinic UV detectors. Second, a spectrophotometer was used to determine the UVR transmittance vs. wavelength (250-440 nm); this data was then used to compute the effective attenuation of the glove material. The average UVA percent transmittance using the radiometer method with an unstretched glove was 73.4%, 0.18%, and 1.10% for vinyl, nitrile, and latex, respectively. The average actinic percent transmittance for an unstretched glove was 13.3%, 0.015%, and 0.024% for vinyl, nitrile, and latex, respectively. Slight increases in UVR transmittance resulted from stretching the gloves by 30% or wetting them with saline. Six hours of UVR exposure decreased transmittance of vinyl gloves and increased transmittance by latex gloves. Results from the spectrophotometer method and radiometer methods of determining UVR transmittance agreed that vinyl gloves had the highest transmittance; however, the spectrophotometer method greatly overestimated UV glove attenuation due to the effect of light scattering by the glove material. The study suggests that in some circumstances, vinyl gloves will provide inadequate protection against workplace ultraviolet radiation.

“…This is more than the effect achieved by dyestuffs. The authors suggested that the detergent should contain about 0.1-0.3% of the special UV absorber (Osterwalder and Rohwer, 2002 ;Osterwalder et al , 2000 ). The same effect can be achieved as early as after one wash cycle with a higher concentration provided by a special laundry additive.…”
