During equipment maintenance, how often should gas samples be taken from inside the equipment for rechecking?
Our factory’s policy is that the validity period of a work permit for entering a container cannot exceed 24 hours. If it isn’t completed in one day, analysis and invoicing must be done again
The system is great; we have learned from it. We hadn’t paid attention to this issue before
There are oxygen concentration monitoring devices, right? They can measure oxygen concentration, combustible gas concentration, and so on. That device can be carried around; all you need to do is bring it with you when working inside the tank. It’s about 5cm*10cm*15cm in size, so it’s convenient to carry around. He operates on a continuous basis, remaining online to conduct analyses using air drawn in through small intake ports. I’ve forgotten the exact name; when the oxygen concentration drops below 19%, or when the concentration of flammable gases rises, an alarm is triggered and a red light comes on – which is very convenient. With that thing, testing can be done at any time; there’s no need to take samples for analysis anymore. We bought one in 2004; it cost a little over 10,000 at that time, and I don’t know how much it costs now.
That is a portable combustible gas detector.
When working inside equipment, it is necessary to understand the chemical and physical properties of the gases present there, as well as any potential effects on humans or safety issues such as poisoning or ignition. After treating the area with steam or water, checks must be carried out to ensure that conditions are within safe limits before work can proceed. If it is the next day, the necessary procedures for working there still need to be followed!
