Figure 1: Confined space with small opening for access.

Typical access into cargo spaces is provided by the ship's ladders. A ship's ladders may be continuous straight ladders reaching up to 90 feet and may be without climbing devices, platforms, or protective cages. Confined spaces often have only one small means of entry. Portable ladders may be used to gain access to these spaces. [29 CFR 1915.72]

Figure 3: Access holes cut into side of ship, and ventilated without blocking exit.
Potential Hazards:
  • Egress from the space may be blocked.
  • There may be only one means of egress from the space.

Requirements and Example Solutions:

  • More than one means of access must be provided to a confined space unless the structure of the vessel makes it impractical. [29 CFR 1915.76(b)(1)]
  • When the ventilation ducts must pass through the entrance of a space, they must allow for free passage. [29 CFR 1915.76(b)(2)] See Figure 2.
    • Note: When there is only one means of access, collapsible ducts may be used to provide access.
  • If ventilation equipment blocks access to the space, airline respirators as well as a stand-by employee must be used. [29 CFR 1915.51(c)(3)]
  • Frequent checks must be conducted to ensure the safety of employees working alone in a confined space. [29 CFR 1915.94]
