Is it necessary to apply upper and lower limits to the dial of the on-site bimetallic thermometer?
Thread Content
Dear teachers, pressure gauges purchased for use on-site come with preset upper and lower limits. The process engineers suggested that upper and lower limits be marked on the dials of bimetallic thermometers used on site; this marking is done by using tape. Is it mandatory to do so?
Keep the operating procedures and parameters in mind. Whether it’s applied or not makes no difference.
Whether it is mandatory to put it on depends on the company’s rules; if there are no such rules, it is optional.
There is absolutely no need to put this up, but some experts will bring this issue up with you. You can discuss it with experts. The issue with the installation process is that they keep arguing; if no agreement can be reached, then both sides should step back a little – you just need to place signs in those important locations where there are significant hazards.
The 5th floor is the correct answer; whoever sees it should post it. The temperature and pressure gauges on site should fall under the category of equipment management related to manufacturing processes
