Are there any requirements regarding the validity period of temporarily removed interlocks?
Thread Content
The interlock protection system has temporarily disabled certain interlocks, and these must be reactivated as soon as possible. Is there a time limit for this?
It depends on the company’s own rules and regulations. At my previous company, the validity period for the shop-floor interlock bypass ticket was 8 hours.
I really don’t know about this. We have interlocked removal here; after going through the approval procedures for removal, it takes a long time before it can be put into use. Once it is used, the system shuts down, and waiting is required until a major maintenance session takes place
The faster the recovery, the better, but I’ve never seen any specific time requirement for it.....
Here, recovery must be achieved 72 hours after the procedure and resection.
I mainly want to know if there are any regulations or standards regarding safety; our company requires a 72-hour period, but I’m not sure where this requirement comes from.
Sinopec used to have a 48-hour period, but this rule has been abolished now; there is no specific specification.
For temporary repairs, we carry out removals within 3 hours; the workshop supervisor needs to sign off on it. If it takes more than a day, approval from the company is required for evaluation~~~~ Try not to perform such removals if possible~~~
Interlocked cutting requires a work order, and such work orders have a time frame; specific rules are set by each factory
