(12) Within a 10-m radius around the construction site, nearby cables, pipelines, and other equipment and facilities must be effectively protected using non-combustible materials, as appropriate; furthermore, non-combustible materials should be used beneath the construction site to catch any sparks. (13) Immediately after completion of construction, withdraw equipment such as welding machines, oxygen, and acetylene to the designated location on the ground. (14) During construction, if the gas concentration within 20 meters of the work area reaches 0.5%, construction must be stopped immediately. The cause must be identified and addressed, and work can resume only after safety is confirmed. (15) Construction workers should promptly extinguish the sparks and embers generated during welding to prevent accidents resulting therefrom. (16) During operations, flammable materials such as coal dust and wood shavings at the work site must be removed to prevent fires. (17) During construction, effective protection should be provided for nearby equipment as appropriate. (18) After the work is completed, spray the construction area with water again and leave someone on site for at least 60 minutes as a supervisor; only after confirming everything is in order can the person leave the site and report to the dispatcher. 9.
