CONFINED SPACE ENTRY:
In order for a work area to be defined as a confined space it must meet all three of the following criteria:
1. Limited Openings for Entry and Exit.
A confined space may be difficult to enter and perform repair work, or general maintenance. If something goes wrong while you are inside a confined space, escape/rescue may be difficult. Just because a work area has more than one way of escape, does not necessarily mean it is not a confined space. If the space has limited ways to get in and out, it could be a confined space. An open top tank would have limited openings for entry and exit.
2. The Space is not intended for Continuous Human Occupancy.
This means that the space was designed to hold something other than people. Examples include tanks and manholes.
3. The Space is Large Enough for You to Enter and Conduct Work.
If you cannot fit your body into the space you cannot become trapped inside.
CONFINED SPACE HAZARDS:
Toxic Gases Hazards (H2S, Cl2, NH3 & CO Gases)
Flammable Gases Hazards (LPG, DA, Hydrogen)
Oxygen Deficiency Hazard
Oxygen Enrichment
Explosion Hazard
Fire Hazard
Excessive Heat Hazard
Physical Hazards:
Noise, heat / cold, radiation, vibration, electrical and Illumination hazard.
Biological Hazards:
Viruses, Bacteria, Sludge, Fungi or molds.
CONFINED SPACE ENTRY CONTROL MEASURES:
The key elements to be considered when drawing up a safe system of work are:
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
Other personal protective equipment
Safe use of work equipment
Communications
Entry & Exit
Flammable or explosive atmospheres
Combustible Materials
