3.5.2 Safety Guide on Ladder Use
Checking the Ladder
Before using the ladder, first check if the ladder is in good condition. Make sure that you
know the maximum weight that the ladder can support; overweight on the ladder is strictly
prohibited.
Placing the Ladder
Slant angle is suggested to be 75 degrees. The slant can be measured with the angle square or
with arms. When using a ladder, place the wider end of the ladder on the ground. Otherwise,
take protective measures on the base part of the ladder to avoid skidding. Place the ladder on
stable ground.
