Issue of not touching the handle of the valve instrument air manual valve
Thread Content
Experts from various fields, please share how your factories prevent accidental activation of the handles on valve and instrument air control valves. What other methods are there besides using zip ties? It would be best to have pictures, thank you
Have you taken your work to such a detail as managing the instrument air manual valves?
This is considered routine work; we have much more detailed tasks to handle
It’s a standard procedure, but we haven’t implemented such detailed measures here yet. The handle of the instrument air manual valve is equipped with a universal unlocking hole, yet no universal unlock device is installed; this universal unlock device is meant to prevent accidental operation of the valve
Our unit has removed all the handles on the instrument air and installed clear warning signs
Remove the handle and put it aside? It’s not very convenient to remove it, right? Is it true that once it’s gone, you have to use an adjustable wrench instead?
It is not recommended; it’s inconvenient in emergency situations
I have to say that working at your company must be quite exhausting
You can buy a better-quality manual valve with a lock. If nothing else works, tie the handle with stainless steel wire
It mainly involves putting up signs with red markings, but it’s still difficult to ensure that such measures won’t lead to shutdowns. It’s better to have higher standards for the people in charge of operations, and there’s also the issue of accountability – if something goes wrong in your area, responsibility falls on you, so they will keep a closer eye on things
