The Confined Space Entry Team

Management Responsibilities

Your safety department will probably be responsible for developing the confined space program. Your line managers should always be responsible for deploying or implementing the program. Remember, safety is a line responsibility, not a staff support responsibility. Line and staff managers should:

  • Ensure that a list of confined spaces is maintained,
  • Ensure that canceled permits are reviewed for lessons learned,
  • Ensure training of entry team members (authorized entrants, attendants, and entry supervisors) and other affected persons are conducted,
  • Ensure coordination with outside emergency responders,
  • Ensure personal protective equipment is in compliance with standards, and
  • Maintain a master inventory of identified confined spaces.

1. Who should be responsible for implementing the confined space program?

a. Safety managers
b. Line managers
c. Employees
d. Entry team supervisors
