When should a service collar be equid?

The service collar should be secured and equid during the process of removing the valve assembly. This is crucial because the service collar is designed to prevent accidental disassembly and ensure that the valve assembly is properly contained during maintenance. When the service collar is equid, it provides a clear assurance that the equipment is in a safe state and minimizes the risk of unintended hazards, such as unintentional activation or leaks.

While there are other important steps pertaining to routine maintenance, pressure checks, and refill procedures, the specific act of removing the valve assembly necessitates that the service collar be secure and equid to maintain safety and prevent operational errors.
