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...

Respirators Instructor Note: Prior to making a safety presentation, obtain and review your company respirator protection program. Our company has developed a separate respirator protection program. It is an important program because of the exposures we face in the workplace. We want to protect your body and lungs. Guide for Discussion Generally: No respiratory program is required when filtering-facepiece respirators are the only respirator used and they are used voluntarily. Respirators will be worn when the employee is exposed to hazards such as fumes, gases, mists, vapors and sprays Fit testing shall occur prior to allowing an employee to wear the Employees should...

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...

Diesel Exhaust What is Diesel Exhaust? The diesel engines in automobiles, buses, and trucks produce exhaust from the combustion of diesel fuel. Diesel exhaust is made up of harmful chemicals including very small toxic particles and hazardous gases. Some of the hazardous gases in diesel exhaust (e.g. nitrogen oxides, benzene, sulfur dioxide and formaldehyde) have been found to possibly cause cancer. Health Hazards of Diesel Exhaust Breathing diesel exhaust is the most common method of exposure. As we breathe, the fine particles and toxic gases in diesel exhaust can enter into the lungs. Being exposed to diesel exhaust for short periods of time may...

Arc Welding 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. 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 it is running or near open...
