There are multiple hazards that can arise regarding cranes in general. If you are working around our equipment, take precautions to ensure your safety. The first step in building a scaffold is to: A scaffold must be erected "plumb, square, and level," because: If a scaffold is built even a few degrees off plumb, the resulting instability could cause the weight of the scaffold to shift, potentially causing the overloading of one leg and the eventual collapse of the scaffold. Respond quickly and efficiently to emergencies by following safety protocols. This is very common in mobile cranes and fixed cranes also used in construction. This scaffold is simply a rope attached to a harness with an assembly like a boatswain's chair for the worker to sit in. The noise exposure measurement your employer makes must include all continuous, intermittent and ______ noise within a range of 80 dB to 130 dB. To prevent employees from entering these hazard areas, the employer must: Before an employee goes to a location in the hazard area that is out of view of the operator, the employee (or someone instructed by the employee) must ensure that the operator is informed that he/she is going to that location. It is designed in such a manner that all overturning forces are counteracted by the concrete pad and the counterweights hanging off the machinery arm. Train each employee assigned to work on or near the equipment ("authorized personnel") in how to recognize struck-by and pinch/crush hazard areas posed by the rotating superstructure. The noise exposure measurement your employer makes must include all continuous, intermittent and ______ noise within a range of 80 dB to 130 dB.
