With normal shielding of UV curing equipment, workers are exposed only to reflections of UV light, and normal work clothing provides adequate attenuation of UV radiation in the workplace. Most polymers and pigments are strong absorbers of UV radiation, so even a thin layer of pigmented nitrile rubber is very effective protection from UV light, which does not have much penetrating power. Even unpigmented gloves should provide adequate protection from reflected UV light.
Of course, worker training to use the correct protective equipment and to recognize the symptoms of over-exposure is essential. The symptoms of over-exposure to UV light are the same as sunburn, so workers will notice very quickly if their protective gloves or clothing are inadequate for conditions, and you can enhance the protection if necessary.

This is all true, but the primary reason for wearing nitrile gloves is not protection from UV light, but rather protection from UV chemicals. Nitrile gloves are the proper PPE for handling UV-curable products. Other types of gloves, such as latex gloves, can allow penetration by UV materials and do not offer suitable protection from the chemical exposure.

ReplyDeleteThis is absolutely right it is a protection from the chemicals and not the light because the rest of the body is anyway exposed to it.But wearing it is definitely a safety measure.
