Confined space could mean or be attributed to any of the following:
Poorly ventilated space or closed apartment with a narrow single entry point or a space with single(narrow) entry point which have been closed for a long period of time.
1. It is not originally designed for human occupancy
2. It has unfavorable natural ventilation
3. limited openings for entry and exit
4. Potentially hazardous
TYPES OF CONFINED SPACE
Confined spaces exist in many settings but are especially common in storage and transportation facilities.
Example of confined space includes:
Pipelines, tunnels, storage Tanks, vessels, sub-cellars, cold storage lockers, hoppers e.t.c
Confined space can be below or above the ground.
A confined space despite its name is not necessarily small.
NATURE OF CONFINED SPACE
Fatal and serious accidents have regularly occurred to workers in confined space as a result of negligence or ignorance of the risk associated with it. The high risk and hazard if not identified and controlled can pose a lot of challenge to the labor force entering it.it is therefore important to identify the hazards and control the risk associated with working in a confined space by the implementation of a confined space hazard assessment and control program.
HAZARDS OF CONFINED SPACE
Confined space hazards can be divided into two major categories:
1. Atmospheric hazards (dangerous air)
2. Physical hazards
