Question 13

• Option a: Lockout/tagout (LOTO) devices aren't only installed by supervisors; employees involved in work can install them as per procedures. So a is incorrect.
• Option b: LOTO equipment isn't applied by the first - arriving employee when multiple employees are involved. Each involved employee has their role in LOTO, so b is incorrect.
• Option c: LOTO devices applied by one employee can't be removed by another just because the first has left. Only the employee who applied or authorized personnel can remove, so c is incorrect.
• Option d: In a LOTO procedure, every employee involved in the work installs LOTO devices to ensure their own safety and proper isolation of energy sources. So d is correct.

• Option a: The National Electrical Code ($\text{NEC}^\circledR$) provides the minimum requirements for the installation of electrical systems to ensure safety and compliance. This is the main purpose of the NEC.
• Option b: The NEC doesn't cover manufacturing specifications for electrical equipment; that's more for product standards and manufacturers' guidelines. So b is incorrect.
• Option c: Workplace hazards associated with electrical equipment are more covered by OSHA standards and other safety regulations, not the NEC. The NEC focuses on installation requirements. So c is incorrect.
• Option d: The NEC isn't about operating instructions for electrical equipment; it's about installation. So d is incorrect.

Answer:

d. Lockout/tagout devices are installed by every employee involved in the work.
