What are some hazardous materials used in welding?

What are some hazardous materials used in welding?

Many of the substances in welding smoke, such as chromium, nickel, arsenic, asbestos, manganese, silica, beryllium, cadmium, nitrogen oxides, phosgene, acrolein, fluorine compounds, carbon monoxide, cobalt, copper, lead, ozone, selenium, and zinc, can be extremely toxic.

What is a potential health hazard of welding shielding gases?

Q: What are the potential health hazards related to shielding gases used in arc welding? A: Most of the shielding gases (argon, helium, and carbon dioxide) are non-toxic, but they can displace oxygen in your breathing air, causing dizziness, unconsciousness, and, possible, death.

What is the hazard of having a high concentration of oxygen in a welding work area?

Eye, nose and throat irritation in low concentrations. Abnormal fluid in the lung and other serious effects at higher concentrations. Chronic effects include lung problems such as emphysema. Welding in confined spaces, and air displacement by shielding gas.

Which type of equipment hazard is a result of repetitive motions during maintenance?

Ergonomic
Ergonomic – repetitive movements, improper set up of workstation, poor design of equipment, workstation design, (postural) or workflow, manual handling, repetitive movement. etc., Physical – Slippery floors, objects in walkways, unsafe or misused machinery, excessive noise, poor lighting, fire.

What is a potential danger of a painted base metal in welding?

Welding and cutting lead-bearing alloys or metals whose surfaces have been painted with lead-based paint can generate lead oxide fumes. The welding area should be ventilated and forced ventilation is best, but natural ventilation is sometimes required.

What are three hazards of welding?

Health hazards from welding, cutting, and brazing operations include exposures to metal fumes and to ultraviolet (UV) radiation. Safety hazards from these operations include burns, eye damage, electrical shock, cuts, and crushed toes and fingers.
