Employer Responsibilities

All employers engaged in construction work must have a competent person:

  1. identify any confined spaces in which their workers will be working, and
  2. determine whether any such spaces are permit spaces.

Competent Person: A competent person is "one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has the authority to take prompt corrective measures to eliminate them."

If an employer knows that a permit space is present at its worksite, warning signs should be used to inform workers of the location and danger posed by each space. If workers have no work to do in the space, the employer must ensure that they recognize permit space warning signs and stay out.

To ensure worker protection, the confined space standard imposes duties on three employer categories:

  1. Entry Employer: An entry employer is an employer who decides that an employee it directs will enter a permit space.
  1. Controlling Contractor: A controlling contractor is the employer with overall responsibility for coordination and control of construction at the worksite.
  1. Host Employer: A host employer is the employer that owns or manages the property where the construction work is taking place.
