UV-resistant screens improve safety in the workplace

Welding and safety screens are aimed at ensuring optimum safety in workshop environments, protecting workers from harsh ultraviolet (UV) light and dangerous UV radiation which occurs during welding and grinding processes.

A range of locally manufactured safety screens incorporates a heavy-duty UV light absorber which safely contains UV radiation in the curtained off area, enhancing safety in the environment and providing protection for workers in close proximity to welding and grinding activities.

Made from specially formulated polyvinyl chloride (PVC) material, Apex Welding and Safety Screens have undergone extensive tests conducted by the South African Bureau of Standards that show superior safety compared to conventional tinted material. Standard tinted PVC material, while offering a visible barrier, was found to provide inadequate protection against UV exposure.

Tested for UV transmittance, the conventional material gave readings of 0.0005%, 0.008% and 5.0% as opposed to readings for the Apex material of 0.005%, 0.001% and 0.005%. When tested for total visible light transmittance, the tests showed that the conventional material allowed 78% light transmittance, while the Apex material allowed only 15.5% light transmittance.

In addition, the company’s welding and safety screens are said to be resistant to burning, which is of particular importance should the material come into contact with welding splatter.

The patented Balledge design on the individual PVC strips facilitates ease of access for personnel and equipment. The strips are designed to part on contact and return to their original configuration, ensuring an efficient close.

Available in several configurations to suit individual requirements, the company affirms that its most popular version is the freestanding frame that facilitates both easy handling and portability. The screens’ angled feet aim to allow optimum utilisation of the floor space and can be positioned together at a 90^o angle.
