There are issues with working with fire.

This workshop is undergoing hot work. It’s just ordinary hot work. System-independent. The safety officer said. There should be no openings through the building within ten meters around. (Including the floor drain) May I ask? Where did those ten-meter corpses come from? Thank you all.
Reply to 1# twtfj: Check AQ3022-2008 (Safety Regulations for Hot Work in Chemical Production Units)
When working with open flames, sparks can spread over a distance of about 5-10 meters. Therefore, **standard regulations require that no flammable or explosive materials be present within 10 meters of the area where the flames are used. Holes in the walls should be covered with wet cotton cloth or metal sheets as a barrier, and someone should be stationed on the floor below to monitor the situation
This makes no sense. What if my framework has a complex structure?
Frame structures must have measures in place to prevent spark spread, and welding is prohibited in strong wind conditions.
This post was last edited by ckwcba on 2011-4-10 at 12:10; the distance of 10 meters is incorrect – it should be 15 meters. Article 5.1.4 of AQ3022－2008 \"Safety Specifications for Hot Work in Chemical Production Units\" stipulates that for hot work carried out in Class A and Class B areas as defined in GB50016, if there are combustible materials, cavities, manholes, ditches, water seals, etc. on the ground, these must be inspected and analyzed; within 15 meters of the area where heating is to take place, measures such as cleaning or sealing must be taken ； For equipment in which flammable or combustible materials may leak around the ignition point, effective spatial isolation measures should be taken.
Those upstairs have already mentioned where the relevant regulations can be found. What I’m talking about here is that when working with fire, it’s necessary to consider the specific circumstances; the person responsible for safety measures must have a thorough understanding of the process involved and be aware of any potential hazards in the area surrounding where the fire is being used. I have been in charge of implementing safety measures for hot work operations on over a thousand occasions, and I have some thoughts on this: to carry out hot work safely and efficiently, it is necessary to have a thorough understanding of the processes, equipment, and the properties of various materials. It’s also important to be well-versed in the environment surrounding the area where hot work is being performed; this helps to ensure both speed and safety. In fact, some of the regulations regarding hot work are quite strict, and in certain working conditions it’s difficult to meet those requirements, yet hot work still has to be carried out.
