Definition - What does Welding Respirator mean?
A welding respirator is a piece of protective equipment that protects welders from fumes. Various designs are available including half mask respirators, powered air purifying respirators and supplied air respirators are used depending on the level of fumes in the workplace. OSHA requires that workers not be exposed to hexavalent chromium and zinc fumes, pollutants produced in the welding process, beyond permissible exposure limits (PELs). Particulate pollution and other fumes can also present hazards. Ways of eliminating the danger through such factors material substitution and improved ventilation are considered first. If it is not possible to reduce exposure through these measures, personal protective equipment is used.
Safeopedia explains Welding Respirator
Since various industries apply welding in a variety of environments, professional consultation is needed in order to determine what precautions should be taken in order to protect employee health in the work environment. A certified health and safety professional or an industrial hygienist with relevant experience in the metalwork field should be consulted. Reviews should be conducted on an annual basis to ensure continued compliance and to adapt the safety program to changes in the work environment. Respirators should be NIOSH certified as this quality standard proves that the respirator is effective. Depending on the materials being used, additional hazardous fumes may be generated during welding.
