Safety in the workplace
Know the area where you will work as much as possible in advance. Please
check:
1. The location of the slope.
2. Open ditch.
3. Falling objects or hanging objects.
3. Soil condition (soft or hard).
4. Standing water and swamp area.
5. Rocks and stumps.
6. Boundary of buried foundations, pillars or walls.
7. Boundary of buried garbage or filling soil.
8. Holes, obstacles, mud or ice.
9. Traffic volume.
10. Dense dust, dense smoke, dense fog.
11. The exact location of buried or suspended pipelines for electricity, gas, telephone, water, sewage or other public
pipelines. If necessary, ask the utility company to mark, close or move these facilities before you start work.
Warning: Before starting the excavation project, please contact the local utility service system
and department.
12. When constructing in a building, figure out the headroom for the head, the porch and the aisle, etc., and the load-
bearing capacity of the floor and ramp. Ensure adequate ventilation during indoor operation. What you are unclear about
will hurt you.
13. Understand the precise distances between wires, telephone lines and machines, and distances between machines
and the ground. If possible, it is best to cut off the power supply. If you can't cut off the power, ask the signalman for
guidance.
Warning: Touching or approaching the power supply or the machine connected to the power
supply can cause electric shock. Do not let any part of the machine get close to the power cord in
the air. Unless necessary safety precautions have been taken. Please be very cautious.
14. Know the depth of underground gas pipes, cables, telephone lines and water pipes, and avoid these areas during
operation, so as not to damage these public facilities.
Warning: if you look in from the damaged cable end, the cut optical fiber will seriously hurt
your eyes.
15. It is forbidden to use this machine in culverts.
16. It is prohibited to operate in mud, mire and marsh.
17. It is forbidden to operate in places where there are chemical hazardous substances.
