Welding can injure both the welder and others working nearby. Welding fumes, vapors, particulates and high intensity light all pose a threat to people that are exposed to them. Temporary or permanent damage to the eyes can result from welding depending on the length and type of exposure. Welding generates metal fumes, chemical gases and vapors. These chemicals can cause irritation of the outer layer of the eye and the cornea.
Visible light from welding processes is very bright and can overwhelm the ability of the iris of the eye to close sufficiently and rapidly enough to limit the brightness of the light reaching the retina. The result is that the light is temporarily blinding and fatiguing to the eye. Hot slag and airborne particulate can impact the eye and cause abrasions, irritation and other surface injuries.
Exposure to high intensity radiation (UV and IR) can cause cataracts, reduced visual acuity, permanent retinal damage, damage to the tissue covering the eye and increased sensitivity to light. UV radiation in a welding arc will burn unprotected skin just like UV radiation in sunlight. This also applies to direct exposure to UV radiation as well as radiation that is reflected from metal surfaces, walls, and ceilings. Consequently, long-term exposure to UV radiation can cause skin cancer.
Understanding the causes of eye damage from welding is important in effectively preventing injury. Wearing safety glasses with side shields or goggles is necessary when chipping or grinding a work piece if you are not wearing a welding helmet. Light filtering curtains and reduced reflective surfaces help protect both welders and observers in the area.
These safety sign was created to last in the toughest industrial environments. These safety signs are available in the classic OSHA format as well as in the ANSI spec. You can choose from any format. These safety signs become encapsulated under high temperature and pressure inside 50 mils of rigid PVC. They are also resistant to chemicals, weather, and physical abuse and tampering. Many of these signs are enhanced with OSHA/ANSI symbols. They can be delivered with either brass eyelets or adhesive mounted. Potential buyers can inquire for prices of semi custom signs and for signs over a quantity of 50.
