What documents are needed for on-site repairs?
Thread Content
Have you encountered such things at instrument repair sites? I measured the resistance value of the thermal resistor on the tower equipment in order to estimate the temperature, but I can’t remember what resistance corresponds to each degree. While looking at the P&ID diagram, I couldn’t remember the meaning of the initial or suffix code for the letter M. The valve positioner shows error code E8; I can’t remember what it means. And so on. The ancients said that a poor memory is better than no pen at all; it would be very convenient to have a small notebook with one, or relevant information stored in a smartphone at such times. This leads me to think: What do you think are the most essential documents to carry when working on instrument repairs?
With one machine in hand, the world is mine. . . A mobile phone is enough
Chemical plants don’t allow phones…
:Lol, really? I have two factories – one is a chemical plant and the other is a fermentation plant – and they don’t allow the use of it on site, but it’s allowed to be used in the corridors or walkways
Many factories don’t allow items to pass through the second gate; it’s not possible to bring them into the production area
In the event of encountering maintenance tasks that are unfamiliar, it is necessary to prepare in advance the corresponding manuals, as well as various homemade tools used for maintenance. The key is proficiency and familiarity. Typically, instrument technicians carry tool bags that, in addition to tools, also include air blowers, cleaning cloths, and precision oiling bottles. It is best to prepare these items based on the actual needs of the work site, so as to avoid unnecessary trips and delays in maintenance tasks; this is provided for reference only.
Check what tools the technicians need; valves usually require wrenches, while instruments don’t. Bring necessary tools, wear appropriate personal protective equipment, carry a walkie-talkie and work permits. Also, have someone from the installation team on standby to provide supervision. Most importantly, have a smart mind – you should know how to handle common problems on your own. In case of an emergency, use the walkie-talkie to ask a colleague for help!
