Welding safety equipment you should know
If you are already a profesional welder,then you should know the fact that welders is really need appropriate clothing to protect them from burns and heat.The most common of all welding injuries is burns,typically result from sparks that land on bare skin, though welding arcs can also cause burns to the skin and eyes.
Before you actually begin to weld, you should thoroughly plan out your safety measures.The first step is actually to ensure that you have everything that is needed to keep you and other people as safe as possible from the violent heat and poisonous substances that are involved in making a weld.
The matter of safety is not an idle concern with welding, because the process involves many extremes and close exposure to very dangerous substances and energies. Using a set of hand tools to work some object carries a few risks you can smash your thumb with a hammer, cut yourself badly with a knife or saw, and so on.However, these relatively limited risks pale next to those that welding threatens including serious burns, blindness, death, and setting entire buildings on fire.
What Welder Should Wear?
Welders should always wear long sleeves and pants. Avoid rolling up sleeves and pant-cuffs because sparks or hot metal can find their way into folds. To keep sparks from falling into your boots, never tuck pants into them. Leather high-top work boots with steel toes are recommended, especially during heavy work. Finally, always wear heavy, flame-resistant gloves, such as leather, to protect your hands from burns, cuts, radiation and electric shock.
Welding safety concerns three general aspects, each of which must be carefully addressed if you are not to risk serious harm to yourself or others. The first facet of welding safety involves items meant to protect you, the welder. Since the glare of an arc welder is strong enough to permanent sear the vision from your eyes simply by looking at it – a process known as abacination – you will need a auto-darkening welding visor to protect your eyes and face. The intense heat of welding can easily sear flesh and produces ultraviolet radiation strong enough to cause skin cancer on exposed skin after a time, so a pair of good welding gloves and heavyweight, long-sleeved shirts made out of natural materials are essential items of welding gear also.
The second is whenever you are welding, insulate yourself to protect against shock. Wear dry gloves with no holes. Moisture increases the potential for and severity of electrical shock, so if you’re working in wet conditions or perspiring heavily, carefully insulate your body from “live” electrical parts including the electrode and metal parts of the electrode holder. Also, keep dry insulation between your body and the metal being welded. Never touch an electrode or metal parts of the electrode holder with skin or wet clothing. And make sure your welding cable and electrode-holder insulation are in good condition.
And the last facet encompasses everything needed to keep the welding process from damaging the physical environment around you – in short, a safe workspace where fumes are properly vented rather than contaminating other occupied spaces, fires are unlikely to start and can be easily contained should they occur, and so forth. You will need a clean, above-ground work area free of flammable items, with volatile liquids stowed in a flammable materials cabinet and a fire extinguisher as well as good set of fire-preventing habits which you should cultivate.
The list Of Welding Safety Equipment
- What is the most common injury to a welder?Burns are the most common injury to welders due to sparks landing on the skin. Welding arcs are very intense and can cause burns to skin and eyes with just a few minutes of exposure.
- What protective clothing is needed in arc welding?Protective clothing needed for welding includes general fire resistant clothing, safety glasses, shoes, gloves, helmet and leathers.
- Can oxy-fuel tinted goggles be used to protect your eyes while arc welding?No, oxy-fuel goggles do not protect your eyes from the intense ultraviolet radiation (UV) produced by the welding arc. A welding helmet with the proper shaded lens must be used whenever welding.
- What types of fabric are recommended for clothing worn when arc welding?Because of its durability and resistance to fire, wool clothing is suggested over synthetics. Synthetics should never be worn because it melts when exposed to extreme heat. Cotton can be worn if it is specially treated for fire retardation.
- What are steps that you can take to prevent hot sparks from being trapped in your clothing?Avoid rolling up your sleeves or pant cuffs, because sparks or hot metal could deposit in the folds. Also, wear your pants outside your work boots, not tucked in, to keep particles from falling into your boots.
- Is it necessary to wear safety glasses if you are already wearing a welding helmet?Even when wearing a helmet, Z87.1 approved safety glasses with side shields, or goggles, should always be worn to protect your eyes from flying particles.
- What types of footwear are recommended for welders?Leather boots with six- to eight-inch ankle coverage are the best foot protection. Where heavy work is done, safety-toe protection boots should be worn. Metatarsal guards over the shoe laces can protect them from falling objects and sparks.
- What types of gloves are suitable for protecting your hands while welding?Heavy, flame-resistant gloves (from materials such as leather) should always be worn to protect your hands and wrists from burns, cuts and scratches. As long as they are dry and in good condition, they will offer some insulation against electric shock.
- What are the two forms of radiation given off by the welding arc?The two types of radiation are Infrared (IR) and Ultraviolet (UV) radiation. IR radiation can cause retinal burning and cataracts. IR can usually be felt as heat. UV radiation, which cannot be felt, can cause an eye burn known as “Welder‘s Flash.”
- How can exposure to IR and UV radiation injure your eyes?It is essential that your eyes are protected from radiation exposure. IR radiation can cause retinal burning and cataracts. IR can usually be felt as heat. UV radiation, which cannot be felt, can cause an eye burn known as “Welder’s Flash.” This condition may not be apparent until several hours after exposure. It can cause extreme discomfort and can result in swelling, fluid excretion and temporary blindness. Normally, “Welder’s Flash” is temporary, but repeated or prolonged exposure can lead to permanent injury of the eyes.
- Is it safe to weld without a welding helmet for a brief period of time, such as during tack welding?Even brief exposure to UV rays can result in a burn to the eyes known as “Welders Flash” which may not be evident until several hours after exposure. It causes extreme discomfort and can result in swelling, fluid excretion from the eyes and even temporary blindness. Normally, this condition is temporary, but repeated overexposure to UV radiation can result in permanent eye damage.
- How do you select the proper filter lens for your welding helmet?The general rule of thumb is to choose a filter too dark to see the arc and then move to the next lighter setting without dropping to below the minimum recommended rating.
- How can you tell that you are being overexposed to radiation from the welding arc?Infrared (IR) radiation cannot be seen but is felt as heat. And there is no way to sense if you are being overexposed to Ultraviolet (UV) radiation – so just do not take any chances and always wear eye and face protection with the proper protective shading.
- How can overexposure to the UV radiation from the welding arc injure you?UV radiation can also burn exposed skin. This process is similar to getting sunburn from overexposure to the sun. Long exposure to arc rays without protection can lead to second and third degree skin buns. Repeated overexposure to ultraviolet radiation is a known cause of skin cancer.
- Is it safe to wear contact lenses while arc welding?Welders should be able to wear contact lenses safely in most situations – provided they wear appropriate industrial eye wear and use the protection we’ve already discussed with respect to protection against arc rays. Anyone wearing contacts on the job should consult with their company medical staff and their own ophthalmologist.
Noise and Hearing Protection
- How can you protect your hearing when arc welding?Earplugs and earmuffs keep metal sparks and airborne particles from entering your ear canal and protect your hearing from the effects of excessive noise.
- How do you know when the noise level to which you are exposed is potentially hazardous?Levels of noise over 85 decibels, averaged over an eight-hour workday, are potentially hazardous to your hearing. When noise levels are painful or are loud enough to interfere with your ability to hear others speaking at a normal conversational volume this is an indication that levels are potentially hazardous.
- How does exposure to high noise levels damage your hearing?The length and number of times you are exposed to high levels of noise determines the extent of the damage to your hearing. High noise levels cause damage to the ear drum and other sensitive parts of your inner ear.
- In addition to wearing hearing protection, what measures can you take to protect yourself from high noise levels?If it is not possible to reduce the level of noise at the source by moving either yourself or the equipment, or by using sound barriers, then you should wear adequate ear protection.
