Confined-Space Entry

What is a confined space? Is it hard to get in and out of? Is it large enough for a person to enter? Is it designed for people to enter into? Could there be hazardous atmosphere inside the space? Are there other hazards that could exist in the space?

Confined spaces, like manholes, pipes, culverts, vaults, storm sewers, water tanks, lift stations, and pits over 4-ft. deep, are enclosed spaces that:

Are large enough for a human being to enter into,
Have a limited or restricted means for entry or exit, and
Are not designed for continuous occupancy.

Only persons who have been trained in confined-space entry can work in a confined space. Persons entering into confined spaces must be aware of the potential hazards, the necessary precautions, the use of appropriate personal protective equipment, and what to do in an emergency. Before entering a confined space, you must be authorized to do so by the confined-space entry supervisor. If there is no entry supervisor, check with your foreman.
