Hazards in Confined Spaces

Working in confined spaces involves many of the same risks as any other work area where similar tasks are performed. However, confined spaces also present unique dangers due to their restricted access and the enclosed nature of the space. Before any workers enter or begin work in a confined space, a competent person should evaluate the space for hazards. If the space cannot be made safe for work, then additional means must be taken to make it safe. Under no circumstances should a worker enter a confined space that has not been approved as safe by a competent person.

Some of the hazards present in confined spaces are as follows:

• Atmospheric hazards
• Fire and explosion hazards
• Power source hazards

Another important consideration is the safety rescue crew. According to the OHS, around 60 percent of fatalities associated with confined spaces are members of a rescue crew. It is essential to have a safe, effective rescue plan and competent rescue crew members so that in case of an emergency, a rescue can be performed with as little risk as possible.
