Any violations must be promptly pointed out by the site manager or safety supervisor
and the involved personnel should be prompted for correction. Personnel who fail to stop
violations will be forbidden from working.
Operators who violate the safety regulations are responsible for accidents caused. The
supervisor has to bear the responsibility accordingly.
Only trained and qualified personnel should perform hoisting operations.
Check that hoisting tools are available and in good condition.
Before hoisting objects, ensure that hoisting tools are firmly secured onto a load-bearing
object or wall.
Ensure that the angle formed by two hoisting cables is no more than 90 degrees, as
shown in the following figure.
