The term 'owner' in pressure equipment includes which of the following?

• A. Only registered users
• B. Only manufacturers
• C. Lessee, person in charge, and those with controlling authority
• D. Insurance agents

Answer: (C)

The term 'owner' in the context of pressure equipment is inclusive of not just the registered users and manufacturers but extends to individuals or entities that have significant responsibilities associated with the equipment. This includes lessees—those who have rented or leased the equipment—as well as the person in charge of the equipment's use and maintenance. Additionally, it encompasses individuals or entities that possess controlling authority over the equipment, which may involve oversight of operational safety and compliance with regulations.

Defining 'owner' in this comprehensive manner is important for regulatory and safety compliance, as each of these groups has a stake in the proper use and maintenance of pressure equipment. Their involvement ensures that all aspects of equipment management are addressed, particularly in the context of safety and legal accountability. This broad definition helps institutions establish clear responsibilities and ensures proper adherence to safety standards.
