⒈ enter the site must comply with safety requirements.
⒉ excavators found pipes, cables and other buried objects shall report, not allowed to deal with.
⒊ soil excavation should pay attention to the stability of the wall and found that cracks and crumbled possible, personnel should immediately leave and timely manner.
⒋ manual digging, after the distance between the operator should not be less than 2m, bulldozers and other than in the 1m height must not exceed 1.5m.
⒌ should be checked daily and the support wall stability of soil, soil and other items may be stacked on the support, not permitted to operate under support.
⒍ mechanical excavators, start preceded by checking the clutch, rope, etc., after commissioning of the normal empty before starting the job.
⒎ machine operations into the shovel should not be too deep to upgrade should not be excessive.
⒏ machinery shall work under the transmission line, the transmission line side of the work, whether in any case, any part of machinery
Location and distance from overhead transmission lines should be consistent with safe operation requirements.
⒐ machinery should be parked on a solid foundation, such as basic too poor to take measures to reinforce the aisle panels shall not be tracked excavators
To the pit side of the stopping distance of 2m, driving; car should not be close to the excavation of earth moving parallel to prevent the collapse overturned.
⒑ within one meter of cable on both sides of artificial excavation.
⒒ with Draglines and slope, clear the end of the workers are not allowed to work in the mechanical radius of gyration.
⒓ to dump the car should be parked in the car after the stabilization is prohibited on the bucket over the cab from the vehicle.
⒔ foundation must be set around 1.5m high railings Protection Gear to set the number of temporary and down the stairs with the Foundation.
⒕ pit road renovations in time to ensure the smooth flow of vehicle safety, all vehicles should be specifically responsible for command guidance.
