Which controls are designed to modify the workplace environment by introducing policies and procedures to reduce exposure?

• A. Engineering Controls
• B. Administrative Controls
• C. Personal Protective Equipment
• D. Welding Controls

Answer: (B)

Administrative controls reduce exposure by altering how work is performed through policies and procedures. They shape the workplace environment by establishing rules, training, safe work practices, scheduling, and permit systems to lower the amount of hazard a worker is exposed to without changing the physical setup or using extra equipment. In welding, this includes things like standardized operating procedures for welding, job rotation to limit time spent near fumes, scheduled breaks, and formal permit-to-work processes for hot tasks.

Engineering controls, by contrast, would involve physical changes to the workplace—such as improved local exhaust ventilation or enclosure of the welding area—while personal protective equipment provides barriers at the worker level, like respirators or gloves. "Welding controls" isn’t a standard category for this purpose.
