How to Avoid Damage Caused by Ultraviolet Rays



The increasing amount of harmful ultraviolet radiation in recent years means safety measures have to be taken all year round, not just in summer.

Do you take appropriate measures against ultraviolet radiation when you are outdoors? Ultraviolet rays pose serious threats to the skin and eyes. People take various measures against ultraviolet radiation and many products are available for purchase. These same ultraviolet rays affect not only the human body, but hoses as well. Vinyl chloride hoses are particularly harmed by ultraviolet rays, resulting in stickiness and stiffness, and olefin hoses become discolored and brittle.

When hoses are used outdoors or in a location with a lot of sunlight, we recommend they be stored after use. Beware: Ultraviolet radiation is present indoors as well. … Fluorescent lights generally used indoors emit ultraviolet rays, sometimes in great quantities, and these rays hasten hose degradation. Therefore, care should be taken even when using hoses indoors.



The table at left shows the difference in ultraviolet radiation may be as much as a factor of 100 between direct sunlight and fluorescent light. Nevertheless, hoses may develop stickiness even when only exposed to fluorescent light.
