Final answer:
Engineering controls refer to physical or mechanical systems designed to minimize workplace hazards and protect workers.
Step-by-step explanation:
The correct answer is option engineering. Welder's helmets and respirators are examples of engineering controls.
In the field of occupational health and safety, engineering controls refer to physical or mechanical systems designed to minimize workplace hazards and protect workers.
These controls are implemented to eliminate or reduce the risk of exposure to hazards, rather than relying on worker behavior or personal protective equipment (PPE) alone.
Welders helmets and respirators are specifically designed engineering controls that protect welders from harmful hazards, such as electric arcs, thermal energy, sparks, and high-energy electromagnetic radiation. They are part of the overall safety measures in welding workplaces to ensure the well-being and safety of workers.
The correct answer is option personal protective equipment (PPE). Welders helmets and respirators are forms of PPE that are used to safeguard workers from workplace hazards. For welders specifically, helmets protect against the intense light and heat from welding, which could cause harm to the eyes and face.
Respirators protect the lungs from inhaling harmful dust, fumes, vapors, or gases. Organizations like OSHA set regulations to ensure the safety of workers by requiring the use of PPE where necessary.
The use of such equipment is a critical aspect of maintaining safety standards and minimizing health risks in hazardous work environments.
Moreover, the development of such safety equipment has evolved over time with advancements in technology, and its use is mandated by laws and regulations aimed at reducing the social costs of pollution and workplace accidents.
This falls under command-and-control regulation which stipulates certain standards and practices to promote a safe working environment.
