Confined Space Entry Training-PPT

What is the Objective of this Training PPT?

Company/Organization require that all employees who must enter into confined spaces receive training as to the hazards, procedures and equipment required to do so safely.


The entrant is the man who enters a confined space. The attendant is the man who stays with the entrant external to the confined space and is accountable for helping the entrant existing to the confined space and calling for emergency assistance when needed.

The health and safety representative is the qualified and competent personnel who evaluates the hazards, defines required devices, equipment and precautions and release/issue the Confined Space Entry Permit.

Goals and Objectives:

At the end of this confined space entry training session, you will:

  1. Be familiar with the hazards and requirements of “safe” confined space entry.
  2. Pass a 10-question quiz with a score of 100%.

Confined Space Entry - Hazards

  1. Both animal and plant life need Oxygen (O2) to survive. One of the basic hazards of entering confined spaces is oxygen deficiency.
  2. When oxygen (O2) is present in concentrations less than 19.5% the atmosphere is said to be Oxygen(O2) deficient.
  3. Oxygen(O2) can also be present in concentrations that are too high.
  4. Oxygen (O2) in concentrations greater than 23% is too oxygen-rich and can cause combustible materials to ignite very quickly.

Oxygen (O2) deficiency can be caused by several processes:


Oxygen(O2) is used up by the person who is in the confined space and turned into carbon dioxide.


Denser materials push Oxygen (O2) out of the occupied space.


Oxygen(O2) is reacted with other materials to make other compounds.

Carbon Dioxide (CO2)

After Oxygen(O2) is delivered to body organs and used by organ cells, it reacts with carbon to make Carbon Dioxide (CO2). Red blood cells carrying Carbon dioxide (CO2) turn blue. Carbon dioxide (CO2) is supplied back to the human/animal’s lungs by the red blood cells and discharged into the surrounding atmosphere. 

Oxygen (O2) 

The human body needs oxygen (O2) to carry out cellular metabolism. Oxygen (O2) is brought in through the lungs and transported to cells of human body organs by the red blood cells. When blood is rich in Oxygen (O2)  it turns red.

Given a fixed amount of oxygen as you would have in a confined space, the respiration of oxygen causes Carbon dioxide (CO2) to increase. When Oxygen(O2) decreases to less than 19.5%. the atmosphere is said to be Oxygen (O2) -deficient, putting occupants of the confined space at risk of losing consciousness and death.
