Safety Hazards in the Welding Shop include: - Flames, sparks, slag, harmful rays, fumes, and fire hazards - Always wear proper PPE in order to minimize risk of being affected by these hazards.
Proper PPE for Welding Safety Glasses – while doing any work at all Leather steel toe boots (non-conductive soles) Non frayed clothing, and no holes Full coverage of body (long sleeves a must) Leather sleeves are preferred Cotton coveralls work well (not oil saturated)
PPE Continued.. Welding helmet with darkening filter plate (1-14) #’s 10 – 14 acceptable for SMAW Welding goggles for Oxy-fuel cutting/welding Full face visor for grinding Welding, gauntlet type gloves Hearing protection Disposable foam or earmuffs
Radiant Energy Hazards Visible Light Can cause eye strain, temporary or permanent blindness Ultraviolet Light Cause burns and blistering of the eyeballs (commonly called arc flash) An electric arc used in welding is 10 times stronger than the sun, because of proximity
Radiant Hazards cont.. Infrared Rays Invisible. Burn the skin or interior of the eye. Can cause retina damage, and over a long term- cataracts.
Burns First, Second, or third degree burns are possible Be careful while transporting hot metals working with hot metals/repositioning your work piece Slag/sparks (cover up)
Fire Prevention Beware of the 3 necessities for a fire to occur Fuel, Heat, and Oxygen Check your surroundings for possible fuel for a fire (flammable gases, wood/paper etc) Do not perform operations you question the safety of Make sure to direct oxy-fuel flame in a safe direction
Welding Fumes and Gases Metal Fume fever- flu like symptoms Occurs after inhaling fumes of certain metal oxides, such as from galvanized steel Metals to be aware of, as they can cause symptoms after inhalation: Aluminum, Beryllium, Cadmium, Chromium, Cobalt, Iron, Lead, Manganese, Nickel, Zinc
Fumes and Gases.. Beware of welding on metal that has paint, rust inhibitor, degreasers etc. on it. To be safe, clean it off first. Welding gases are not healthy to breath in any large quantity… The act of welding also creates fumes and gases.. What should we do about this??
Welding Ventilation Keep your head out of the plume Use natural ventilation: Open doors Mechanical ventilation: Fans Local Ventilation: Place above the fumes the best you can
Avoiding Electric Shock Clothing: avoid damp clothing Electrode holders: do not touch the metal parts to your skin or damp clothing Make sure to switch machine off if you are not going to use it, and take the electrode out of the electrode holder
Goal: Zero injuries Always ask if you are unsure Work at a pace that is safe- don’t hurry Use tools and equipment you are trained on Value your safety and the safety of others.. It’s a long life.
