Final answer:
OSHA requires lockout and tagout devices to be standardized by color coding, shape, or size to enhance safety and prevent workplace errors.
Step-by-step explanation:
The question pertains to the Occupational Safety and Health Administration's (OSHA) standards on lockout and tagout devices, which are critical for ensuring the safety of workers around machinery and equipment that could be harmful if unexpectedly energized. According to 29 CFR 1910.147(c)(5)(ii)(B), lockout and tagout devices must be standardized by at least one of the following criteria: color coding, shape, or size. This standardization helps to prevent errors in the workplace by ensuring that these safety devices are easily recognizable and understood by all employees.
