Protection against suffocation and object strikes, as well as prevention of related hazards.
During the operation, a person’s head may be below ground level, posing a risk of poisoning and suffocation
When workers are working while bent over, the vertical distance between their heads and the ground is approximately 1.2 meters; therefore, 1.2 meters is used as the threshold for determining whether work in a confined space is involved.
When working at low heights, there are risks of object strikes, asphyxiation, and drowning
