Confined Space: What it is and how to prepare
From potentially toxic atmospheres, to physically hazardous conditions such as extreme temperatures, unstable materials, or the potential for falls, confined spaces often present unseen challenges.
Confined spaces are areas that meet all of the following criteria:
- Large enough for workers to enter and perform certain jobs
- Limited or restricted means for entry or exit
- Not designed for continuous occupancy
