Safety第 93 / 100 题
When lifting heavy bags of soil or stone, the correct technique is to do what?
a.Bend at the waist and twist while lifting
b.Lift with straight legs and a rounded back
c.Bend the knees, keep the back straight, and lift with the legs
d.Hold the load far from the body
解析
Safe lifting keeps the back straight, bends the knees, and uses the leg muscles to raise the load held close to the body, avoiding twisting. This reduces strain on the lower back, a leading source of landscaping injuries. Heavy or awkward loads should be split or team-lifted.
