Hoisting Devices

Do not walk under hoisted objects.

  • 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.

  • Do not drag steel ropes and hoisting tools or bump hoisted objects against hard objects during hoisting.

Using Ladders

  • Use wooden or fiberglass ladders when you need to perform live working at heights.
  • When a step ladder is used, ensure that the pull ropes are secured and the ladder is held firm.
  • Before using a ladder, check that it is intact and confirm its load bearing capacity. Do not overload it.
  • Ensure that the wider end of the ladder is at the bottom, or protective measures have been taken at the bottom to prevent the ladder from sliding.
  • Ensure that the ladder is securely positioned. The recommended angle for a ladder against the floor is 75 degrees, as shown in the following figure. An angle rule can be used to measure the angle.

  • When climbing a ladder, take the following precautions to reduce risks and ensure safety:
  • Keep your body steady.
  • Do not climb higher than the fourth rung of the ladder from the top.
  • Ensure that your body's center of gravity does not shift outside the legs of the ladder.

Drilling Holes

  • When drilling holes into a wall or floor, observe the following safety precautions: Wear goggles and protective gloves when drilling holes.
  • When drilling holes, protect the equipment from shavings. After drilling, clean up any shavings that have accumulated inside or outside the equipment.

Moving Heavy Objects

  • Be cautious to avoid injury when moving heavy objects.

  • When moving the equipment by hand, wear protective gloves to prevent injuries.
