Preventing Injury from Equipment Over Pressurization
What are the potential causes of injury due to equipment over pressurization?
A) Excessive force when opening or closing a valve
B) Throttling a valve that is not designed for throttling
C) Failure to clean and lubricate valve stems
D) Improper closing of a valve on a high-pressure line
Answer:
Over pressurization of equipment can cause injury due to excessive force when opening or closing a valve, throttling a valve not designed for throttling, and improper closing of a valve on a high-pressure line.
Over pressurization of equipment can lead to serious injuries in various ways. Let's delve into each potential cause:
Excessive force when opening or closing a valve:
If a valve is over pressurized, it can be challenging to open or close, requiring excessive force. This excessive force can lead to strains, sprains, or even more severe injuries.
Throttling a valve that is not designed for throttling:
Some valves are not meant to be partially opened or closed. Throttling such valves can result in equipment failure and pose a risk of injury to those operating the valves or those nearby.
Improper closing of a valve on a high-pressure line:
When a valve is not correctly closed on a high-pressure line, there is a risk of sudden pressure release, which can cause severe injuries to individuals in the vicinity. It is crucial to follow proper procedures when closing valves to prevent such accidents.
It is essential for individuals working with pressurized equipment to receive proper training on how to safely operate valves and maintain equipment to prevent over pressurization-related injuries.
