Do you know if your safety Valves are safe?
The important way to prevention and release of hazardous energy
during service or maintenance activity is by using an energy-isolating device
which is manually operated to lockout energy storing devices such as Valves.
Lockout requires the use of a lock or other lockout device to hold
the energy-isolating device in a safe position to prevent machinery from
becoming reenergized. The lockout also requires employees to follow an
established procedure to ensure that all machinery will not be re-energized
until the same employee who placed the lockout device on the energy-isolating
device removes it.
Valve
lockout devices:
A wide variety of valves supply liquids, compressed gases, steam,
and more in an operating facility. A valve lockout device will conceal or
physically prevent the valve’s operation temporarily or for a prolonged
duration. The four main types of Valves commonly user are Gate valves, Ball valves, Plug valves, and Butterfly valves.
Two Types of Locking:
If the
valve is being guarded against inadvertent operation for example a sprinkler
system, or a far more critical process event like the isolation of a safety
relief valve, it’s common practice that valves need to be locked.
A: Valves which operate with a wheel are
simple locking problems to solve. A chain or a the cable is wrapped around such
the wheel rim or spokes, and again around something fixed nearby support or
some pipework or secured in place with a padlock.
B: Valves which turn through 90° via a
lever or wrench are more problematic because the chain or cable can slide off
the end of the lever negating the locking function.
Without
such functionality integral to the valve design, operators adopt many types of
after-market or retrofit incorrect systems that can lead to accidents or
disasters cue an incorrect procedure or a device used to secure/lock the valve.
Building a
Lockout Program:
It is important for all companies to build a
lockout program to put in place safety procedures. Valves safety Lockout
programs are often tricky; however, an effective one can make all the
difference!
1.
Create a detailed
lock out tag out procedure.
2.
Notify affected
employees.
3.
Make the
procedures easy accessible.
4.
Follow the
detailed procedures.
5.
Swap correctly
during shift changes
6.
Train employees
on using lockout devices and the importance of respecting locked and tagged
hazardous energy.
7.
Review and audit procedures
regularly.
