HEALTH HAZARDS OF WELDING FUMES.pdf

Welding gases and fumes pose a serious threat to anyone who inhales them. Every welding project emits a different combination of gases. The fumes can cause occupational asthma and damage the nervous system. Keeping your head out of the plume while welding is one of the best ways workers can protect themselves from harmful exposure.

Welders are at the highest risk for exposure to welding gases and fumes, but anyone who works near a welder can also inhale welding fumes. This is especially true indoors or in confined spaces. In those areas, fumes can't dissipate and hazardous levels can build up. Workers in an enclosure or confined space with a welder should assume that they are at the same level of risk as the welder. Welding fumes are made of many different metallic components. Each fume will be different depending on the material being welded, the electrode, and the type of welding.

The airborne gases and fumes produced or present during welding can include:. There are health effects for both short-term and long-term exposure to these gases and fumes.

They include:. The best way to reduce the risk of exposure to welding gases and fumes is to eliminate the source of exposure. If that's not possible, there are other risk controls to use. When choosing risk controls, start by asking the questions in the following steps, listed in order of effectiveness. Eliminating the hazard by substituting a safer process or material, where possible, is the most effective control.

Some questions to consider:. Making physical modifications to facilities, equipment, and processes can reduce exposure. Changing work practices and work policies, and using awareness tools and training can limit the risk of exposure to welding gases and fumes. This is the least preferred control. It must always be used in addition to at least one other control. Workers who perform welding activities may be exposed to fumes that contain metals and chemicals, putting them at risk of illness and disease.

Some questions to consider: Can less hazardous materials like manganese-free welding rods be used? Can a process that generates fewer gases or fumes be used, such as cold joining? Engineering controls Making physical modifications to facilities, equipment, and processes can reduce exposure. Some questions to consider: Can general ventilation be improved? Can fans be set up to move the smoke away from the welder and other workers?

Can local exhaust ventilation be used to remove contaminated air? Can turntables be used so welders can sit and position the material so gases and fumes don't cross their face? Administrative controls Changing work practices and work policies, and using awareness tools and training can limit the risk of exposure to welding gases and fumes. Some questions to consider: Has an exposure control plan been developed?

Can warning signs be posted in the work area? Can workers be scheduled away from areas being used for large welding jobs? Can change areas provide separate stations for work and street clothes? Can a hygiene awareness program be implemented? Personal protective equipment This is the least preferred control.

Some questions to consider: Do workers have appropriate respirators, eyewear, and protective clothing? Have workers been fit-tested to ensure respirators are working effectively? Has personal protective equipment been verified to ensure it is working properly?

Welding is a common industrial process and is harmful to welders' health. To determine the effect of toxic gases and metal fumes produced during 3 welding processes on welders' incidence of respiratory symptoms and pulmonary function. This cross-sectional study was conducted in an Iranian shipbuilding industrial factory in Using the simple census method, 60 welders were selected as the exposed group. Welders' demographic data and respiratory complaints were collected employing a questionnaire. Pulmonary function test was also performed for each participant.

Metrics details. Welding fumes consist of a wide range of complex metal oxide particles which can be deposited in all regions of the respiratory tract. Over , welders were reported in the U. Many health effects are presently under investigation from exposure to welding fumes. Welding fume pulmonary effects have been associated with bronchitis, metal fume fever, cancer and functional changes in the lung. Our investigation focused on the generation of free radicals and reactive oxygen species from stainless and mild steel welding fumes generated by a gas metal arc robotic welder. Our results show that hydroxyl radicals.

New environmental, health and safety legislation, both in the EU and in the USA, is driving the need for the study of new welding processes, and the selection of the operational procedures that will reduce fume emissions and will promote a healthier, safer and more productive work environment.
