Working at Heights
Warning:
When working at heights, take care to prevent objects from falling.
Working at heights should conform to the related national service
regulation requirements:
Operators working at heights must have been specially trained.
Take care of the operation machinery and tools to prevent them from
falling.
Take safety precautions, and wear helmet and safety belt.
In cold areas, wear cold-protection clothes before working at heights.
Before working at heights, check all hoisting equipment.
Hoisting Heavy Objects
Warning:
Do not walk about right under the boom and hoisted objected when
heavy objects are hoisted.
When disassembling heavy equipment, or moving and replacing
equipment, make sure there are facilities of proper hoisting capability.
Personnel engaged in the hoisting work must have received relevant
trainings. The tools used for hoisting must have been inspected to ensure
they are tightly fixed on the weight-bearing object or the wall. Use brief
hoisting commands to prevent misoperations.
Using Ladders
Before using ladders, make sure they are in good condition and can be
used through inspection. Over-weight is forbidden during the use of
ladders.
When a ladder tilts more than 5 meters, or a straight two-foot ladder tilts
over 3 meters or when operations are conducted in a dangerous
environment, it is required to have the ladder supported or take other
security measures. A-shape ladders should be fully unfolded when used.
