Confined Space Safe Work Practices

Demolition contractors often come in contact with confined spaces when demolishing structures at industrial sites.

Actual confined space on a demolition site and some of the hazards it presents.
Confined spaces are potential hazards on demolition sites.

These confined spaces can be generally categorized in two major groups:

  1. those with open tops and a depth that restricts the natural movement of air
  2. enclosed spaces with very limited openings for entry

Examples of these spaces include storage tanks, vessels, degreasers, pits vaults, casing, and silos.

The hazards encountered when entering and working in confined spaces are capable of causing bodily injury, illness, and death.

Accidents occur among workers because of failure to recognize that a confined space is a potential hazard. It should therefore be considered that the most unfavorable situation exists in every case and that the danger of explosion, poisoning, and asphyxiation will be present at the onset of entry.
