Health And Safety Uv Light
Uv radiation is absorbed in the skin and the adverse health effects are mostly confined to the skin and eyes.
Health and safety uv light. Uv radiation can cause injuries and ill health either in the short term eg sunburnt skin or conjunctivitis or in the long term eg premature skin ageing skin cancer and cataracts. We can t see it ourselves though it is present in sunlight and pretty good at damaging our dna. Disinfection by way of uv light is nothing new.
The adverse health effects that may occur are erythema sunburn photokeratitis a feeling of sand in the eyes skin cancer melanoma cataracts and retinal burns. The most hazardous uv radiation emitted by the uv lamps is that with wavelengths between 240 and 315 nm. The risk may increase if the.
Uv radiation is known to cause adverse health effects that can manifest over both the short and long term. The international ultraviolet association says it s been a useful technology for over 40 years contributing to clean water and clean air. Designed to help employers to meet their legal obligations for the safe use of uv light in the workplace under the control of artificial optical radiation at work regulations 2010.
On the other hand over exposure to uv light can cause adverse health effects such as erythema sunburn photoconjunctivitis and photokeratitis arc eye in the short term acute effects and can be attributed to premature skin ageing skin cancer and cataracts as a result of repeated exposure in the long term chronic effects. Excessive uv light exposure can cause painful sunburn accelerate wrinkling and increase the risk of skin cancer. Uv can be associated with adverse health effects depending on duration of exposure and the wavelength.
One day course aimed at health and safety professionals and those responsible for ensuring the safe use of uv light equipment in the workplace. However too much exposure can be harmful to the skin and eyes. In most cases it is considered that shorter wavelengths uvb are more harmful than longer wavelengths uva.
Uv light can cause eye inflammation cataracts and retinal damage. In this range the threshold limit value tlv is less than 10 millijoules per square centimeter and the most restrictive tlv is the uv c at 270 nm which is set at 3 millijoules per square centimeter.
