NALMCO Certified Apprentice Lighting Technician (CALT) Practice Exam

Why is the OSHA lockout/tagout rule essential?

1. Reduces energy consumption, which can reduce owner operating costs

2. Economizes on labor, which can reduce owner operating costs

3. Raises light levels, which can increase worker satisfaction

4. Prevents electric shock by ensuring all lighting circuits are deenergized

The correct answer is: Prevents electric shock by ensuring all lighting circuits are deenergized

The OSHA lockout/tagout rule is essential primarily because it is designed to prevent electric shock and other injuries by ensuring that all lighting circuits and equipment are completely deenergized before maintenance or servicing work begins. This procedure creates a safe environment for workers by minimizing the risks associated with the unexpected release of hazardous energy. When technicians properly employ lockout/tagout procedures, they use locks or tags to prevent others from energizing the equipment while someone is working on it. This is vital in maintaining a safe workplace, as it provides assurance to the workers that the equipment cannot be accidentally activated during maintenance. While reducing energy consumption and labor costs or increasing light levels can also contribute to workplace efficiency and satisfaction, the primary intent of the lockout/tagout rule lies in employee safety, making it a critical aspect of workplace protocols in the maintenance of lighting and electrical systems.
