Who is allowed to enter major electrical installations?

• A. Authorized persons
• B. Any employee
• C. Visitors with supervision
• D. Electricians only

Answer: (A)

Access to major electrical installations is restricted because of the high hazards present, such as shock and arc flash. The best choice is authorized persons—those who have been granted permission and the required training and clearance to enter, often under a permit-to-work system and with proper supervision or PPE. This ensures anyone entering understands the specific hazards, knows the safety procedures, and is prepared to follow proper lockout/tagout and other protections. Why not every employee? Not every worker has the necessary training, authorization, or need to access high-risk electrical spaces. Visitors with supervision are allowed only in tightly controlled scenarios and for a limited purpose, not as a general rule. And restricting access to electricians only ignores other trained and authorized personnel who may need to perform maintenance, inspections, or safety checks.
