Confined space hazards can be divided into four broad and far reaching categories. These categories are Configuration, Biological, Physical and Atmospheric. It is important to understand each of these groupings as they are often used in the classification of specific confined spaces hazards at a worksite.

A confined space also has limited or restricted means for entry or exit and is not designed for continuous occupancy. Confined spaces include, but are not limited to, tanks, vessels, silos, storage bins, hoppers, vaults, pits, manholes, tunnels, equipment housings, ductwork, pipelines, etc.

In order for a work area to be defined as a confined space it must meet all three of the following criteria: Limited Openings for Entry and Exit. ... The Space is not Intended for Continuous Human Occupancy. ... The Space is Large Enough for You to Enter and Conduct Work.

What are the key elements of a safe system of work for a confined space? Competence, training, supervision and suitability. Permit-to-work procedure. Gas purging and ventilation. Dangerous residues. Testing and monitoring of the atmosphere. Mechanical, electrical and process isolation. Respiratory protective equipment.

Definitions. confined space: A space that has limited or restricted means of entry, is not designed for continuous occupancy, and is large enough and configured so that a person can enter the space and maneuver well enough to perform tasks.

The space must be “large enough and so configured that an employee can bodily enter and performed assigned work” AND. The space must “have limited or restricted means for entry or exit” AND. The space must not be “designed for continuous employee occupancy”.

Confined space authorization signs mark dangerous areas that require a permit to enter. These signs are commonly posted where there is a danger of being trapped or engulfed by flame or water. These signs increase awareness and help minimize the risk of accidents.
