#264 Confined Spaces Construction
Before it begins work at a worksite, each employer shall ensure that a competent person identifies all confined spaces in which one or more of the employees it directs may work, and identifies each space that is a permit space, through consideration and evaluation of the elements of that space, including testing as necessary.
If the workplace contains one or more permit spaces, the employer who identifies, or who receives notice of, a permit space shall:
- Inform exposed employees by posting danger signs or by any other equally effective means, of the existence and location of, and the danger posed by, each permit space; and NOTE to Section 1952(b)(1): A sign reading “DANGER — PERMIT-REQUIRED CONFINED SPACE, DO NOT ENTER” or using other similar language would satisfy the requirement for a sign.
- Inform, in a timely manner and in a manner other than posting, its employees’ authorized representatives and the controlling contractor of the existence and location of, and the danger posed by, each permit space.
Each employer who identifies, or receives notice of, a permit space and has not authorized employees it directs to work in that space shall take effective measures to prevent those employees from entering that permit space, in addition to complying with all other applicable requirements of this standard.
If any employer decides that employees it directs will enter a permit space, that employer shall have a written permit space program that complies with Section 1953 implemented at the construction site. The written program shall be made available prior to and during entry operations for inspection by employees and their authorized representatives.
