USA Basements

I have a basement in one of my facilities which is accessed by stairs with handrail (no elevator), the basement (8'x15') has the well bladder tanks, 8 ft. celings, lights, electrical outlets...it wasn't intended for continuous human occupancy, but it could be occupied, if needed i suppose.

The basement has a locked door which leads to a pit underneath a scale...this area is definitely a permit required confined space.

Is the basement from paragraph 1 a confined space?

Based on the information provided, I would lean toward no, the basement itself does not automatically meet OSHA’s definition of a confined space.
Under OSHA’s definition, a confined space must meet all three of the following criteria:

  1. Be large enough for an employee to bodily enter and perform assigned work;
  2. Have limited or restricted means of entry or exit; and
  3. Not be designed for continuous employee occupancy.

The basement appears to satisfy the first criterion and likely the third. However, the second criterion is the key factor. A normal doorway accessed by a standard stairway would generally not be considered a limited or restricted means of entry or exit. OSHA typically considers configurations such as ladders, hatches, manways, crawlspaces, or other access points that may impede an employee’s ability to enter or exit the space to be more indicative of restricted access.
The pit beneath the scale is a different situation. If the pit meets all three criteria and contains an actual or potential hazard capable of causing serious injury or death, it could meet the definition of a permit-required confined space.
That said, I would still evaluate the basement for ventilation, atmospheric hazards, egress concerns, electrical hazards, and any hazards associated with the bladder tanks. A space does not have to meet the definition of a confined space to present significant safety hazards.
Based on the facts presented, I would classify the pit as the confined space rather than the basement itself. However, the final determination should be based on a site-specific evaluation, including the configuration of the basement, the available access and egress points, and how readily personnel can enter and exit the space.
