3. Confined spaces
• A confined space is an enclosed area with limited space and
accessibility.
(From Wikipedia)

5. What is the hazard?
• A hazard is a situation that poses a level of threat to life, health,
property, or environment.
(From Wikipedia)

6. What is Safety?
• It is defined as the control of recognized hazards to achieve an a
cceptable level of risk. This can take the form of being protected f
rom the event or from exposure to something that causes health
or economical losses.

7. Example of confined spaces in constructi
on field

8. General Hazards in confined spaces
• Radiation
• Toxic atmospheres
• Temperature extremes

9. • Explosive atmospheres
• Oxygen: too little
• Falling objects

10. • Low light
• Electrical shock
• Noise

11. Why is working in a confined space
more hazardous than working in other
workspaces?
• The entrance/exit of the confined space might not allow the
worker to get out in time should there be a flood or collapse of
free-flowing solid.
• Rescue of the victim is more difficult. The interior configuration of
the confined space often does not allow easy movement
of people or equipment within it.
• Natural ventilation alone will often not be sufficient to maintain
breathable quality air. The interior configuration of the confined
space does not allow easy movement of air within it.
• Conditions can change very quickly.
• The space outside the confined space can impact on the
conditions inside the confined space and vice versa.
• Work activities may introduce hazards not present initially.

12. Safety Procedures
• First we do the air quality check before enter the
confined space
• Safety officer should observe following safety ite
ms
in strictly
– Wearing shoes ,gloves and helmet
– Use the safety belt
– Use the masks, head phones and glass
– Don’t smoke , drinking in confine spaces
• Should displayed the safety symbols and boards
about the danger of confined spaces at near tha
t place

13. • Use Mechanical ventilation (blowers, fans) is usually
necessary to maintain air quality.
• Should maintain the space is clear
• Don’t allow unauthorized persons in confined spaces
• Have a emergency subway
• Allow the limited laborers in side of confined spaces
