What safety precautions should safety supervisors at on-site soil dynamic compaction sites take

(2) Construction workers must wear safety helmets when entering the site, and must wear safety belts when working at heights. (3) For the operation, maintenance, inspection of all construction machinery and equipment, as well as their safety protection devices, a pre-shift safety inspection system and a safety self-inspection system for the construction teams must be implemented. Any potential safety hazards related to equipment and tools must be eliminated immediately; it is not allowed for such equipment and tools to be used while having defects. (4) During construction, the crane must be leveled at all times; pulling or lifting it at an angle is strictly prohibited to prevent accidents such as bent or collapsed cranes. (5) When it is difficult to lift the ram due to the deep ramming pit, a trial lift should be carried out first; only after it becomes loose should the actual lifting proceed, in order to prevent the rammer from operating under overload and causing it to tip over. (6) When moving the rammer, the height of the hammer lift should not exceed 0.5 m; other crew members should accompany it to monitor the ground conditions, and if any abnormalities are detected, the machine should be stopped immediately for handling. (7) If gantry construction is used, the two legs must be leveled and secured firmly, and they should be at the same elevation. When lifting the ram, a trial lift should be conducted first; only after confirming that the gantry is stable should the ram be lifted officially. Lifting diagonally to the left or right is strictly prohibited to prevent the gantry from losing stability. (8) When the uncoupler fails and the ram hammer cannot be disengaged, slow descent measures must be taken; it is strictly prohibited to force the swing arm to turn or to allow the hooked part to fall freely. (9) The minimum safe operating distance between adjacent units should not be less than 30 m. (10) All temporary electrical facilities at the construction site, such as the installation of wires and cables, the setup of power distribution equipment, the provision of safety protection devices, as well as the management and maintenance of electrical equipment, shall comply with the provisions of the \"Code for Safety in Power Supply and Use at Construction Sites\" GB 50194—93 ； A full-time electrician must be assigned to the site to ensure electrical safety at the construction location; regular inspections should be carried out, and any abnormalities found should be repaired or replaced promptly. (11) Clear warning signs should be installed at the construction site, and unauthorized persons are strictly prohibited from entering. Nighttime construction must have sufficient lighting, and dedicated supervisors should be assigned to be on duty. (12) During the rainy season, construction work should primarily focus on measures to protect against rain, wind, lightning, and electric shocks ； Construction work is prohibited during thunderstorms and winds of force 6. (13) The site should have appropriate drainage slopes and drainage facilities; when the site becomes flooded after rain and the strength of the foundation decreases, measures such as laying \"foundation boxes\" can be taken to ensure the safe operation of the dynamic compaction machine. Civilized construction: (1) Clothing and personal protective equipment must be neat and complete; dormitories should be clean and tidy, with items arranged in an orderly manner. (2) Keep the mechanical equipment in use clean and maintain it as specified. Park neatly and do not occupy the roads within the area indiscriminately. (3) Comply with all rules and regulations as well as laws and statutes. Do not violate labor discipline. (4) Ensure strict compliance with relevant safety operating procedures, and avoid giving orders or performing operations in violation of regulations. (5) Regularly clean up waste at the construction site to keep it tidy. Temporary toilets are set up on site, and waste materials are disposed of or buried in a centralized manner as required. ——————————————————————————————————--Taken from the Internet; in my opinion, it simply means adhering to safety regulations ； Strengthen personnel training and on-site management ； Procedures for wearing personal protective equipment! Supervisors should take protective measures during construction, staying as far away as possible to avoid being injured by flying debris. . . .

What distance should supervisors maintain from ramming machines? Are there any relevant standard requirements? Additionally, what safety accidents are likely to occur during dynamic compaction operations?
