Hot Work Procedures Hot work may include spark and high heat-producing job tasks such as grinding, welding, soldering, thermal or oxygen cutting or heating. Advanced planning and safe work procedures help prevent workplace fires caused by hot work activities. Get training on hot works tools and processes. Know how to assess the fire risk, prevent fire, extinguish a fire, and activate an emergency response. If you are a designated fire watch, get annual training on these procedures. Wear the appropriate personal protective equipment for hot work, including tinted eye protection and a face shield. Wear fire-retardant clothing and a welding vest and...

Preventing Welding Flashback Oxy-acetylene torches have been used for many years for cutting, welding, brazing, and heating of metals. The equipment used today is safe, but every year, hundreds of employees are injured or die as a result of improper use. Knowledge and precautions can prevent fires and violent explosions. Gas Pressure: One cause of fires and explosions is high acetylene pressure. When more than 15 pounds of pressure is used, acetylene becomes unstable and decomposes explosively. This is the major reason for using other fuel gases such as MAPP, propylene, propane, and natural gas which may be safely used at higher...

Welding On Galvanized Metals One of the most significant health hazards in the welding process is the generation of fumes and gasses. Do you weld on galvanized metals? Zinc is the coating used on galvanized metals, and when you heat the metal, it produces vaporized metal droplets which are called fumes. This is the smoky haze which consists of fine particles of metals or silicates. When you breathe these fumes, they may work deeply into your lungs. The typical effect of breathing zinc fumes is metal fume fever. One or two hours or more after welding-without proper personal protection-you may experience severe...

Ventilation - An Important Aspect Of Welding Safety - Without proper ventilation, the fumes produced in a welding operation can be hazardous to the welder or workers in the near vicinity. Reducing the exposure to fumes through an effective local exhaust or area ventilation system is the first line of defense in preventing discomfort or illnesses from toxic welding fumes. Respirators are another means of reducing exposure. This personal protective equipment should be considered a temporary process until more appropriate measures to control the exposure are in place. However, when the level of the exposure cannot be entirely eliminated by an exhaust ventilation...

What You Need To Know About Welding & Cutting Protecting yourself when performing welding operations depends on your understanding of the hazards involved and the proper way to control them. Control of welding hazards includes avoiding eye injury, respiratory protection, ventilation of the work area, protective clothing and having safe equipment to use. Eye hazards include exposure to ultraviolet and infrared light. Welders and their helpers should wear filter glasses with shades ranging from 2 to 14, depending on the type of welding being done, to protect their eyes. Unless a welding arc is behind a screen, not only the welder, but...

Warning: Welding May be Hazardous to your Health You’ve heard the expression, “You are what you eat.” Well, with welding, one could say you are what you breathe. Welding smoke is a complex mixture of very small, condensed solids (fumes) and gases. The base and filler metals, fluxes, coatings, and shielding gases all contribute. Even chemical changes to the surrounding atmosphere from the intense radiation and heat can add to the mix. The effects of welding smoke on a person will depend on the particular components of the smoke and how much of it the welder breathes. Some effects may occur shortly after...

Arc Welding Safety Arc welders use a powerful electric arc to make and repair plain, coated, or treated metal items. Welders can be stationary, electric powered or portable, diesel/gas powered. Install electric-powered arc welders to code. To provide arc welding safety, ground equipment and place it on an independent circuit with the correct-sized fuse or circuit breaker. Overloading circuits or improper installation can lead to fire, a ground fault, or equipment failure. Mount a safety disconnect switch near the user work area. Operate diesel/gas powered arc welders in well-ventilated areas to control combustion fumes. Do not add fuel to the engine while...

Auto Body Work Repairing auto body damage requires sanding, grinding, and sometimes welding to repair the vehicle before it can be refinished. Get training in collision repair. Know the techniques and tools to complete bodywork. Review the Safety Data Sheets (SDS) for the chemicals you use to identify the personal protective equipment (PPE) to wear and how to mix and use materials properly. Eye injuries are common in auto body shops. Always wear eye protection when you are grinding, sanding, welding, and painting. Safety eyeglasses, goggles, and/or shields can protect your eyes from flying particles, sparks, and splashes. Grinding and sanding the paint off...

Welding Safety Welding hazards pose an unusual combination of safety and health risks.  By its nature, welding produces fumes and noise, gives off radiation, involves electricity or gases, and has the potential for burns, shock, fire, and explosions. Some hazards are common to both electric arc and oxygen-fuel gas welding.  If you work with or near a welding operation, the following general precautions should help you to work more safely. Weld only in designated areas. Only operate welding equipment you have been trained to use. Know what the substance is that’s being welded and any coating on it. Wear protective clothing to...
