3.4.1 The Safety Codes on Ladder-using
Before using the ladder, first check if the ladder is damaged. Make sure the ladder is
safe for use. Overweight on the ladder is strictly prohibited.
The slant of the ladder is 75
°
at best. The slant can be measured with Angle Square or
with arms. When a ladder is used, the wider end of the ladder should be placed against
the ground or protective measures should be taken on the base part of the ladder for
the purpose of skid resistance. Place the ladder against a stable ground.
When climbing the ladder, do not deviate your center of gravity from the ladder edge. To
lessen the danger and ensure safety, three parts of the body should be on the ladder.
When climbing the ladder, the upper limit of the height should not exceed the highest
four steps. If one is about to climb to the top, the length of the ladder should be 1 meter
higher than the eave.

command to avoid mis-operation.
