If a worker on a scaffold can fall more than 10 feet, they must be protected by guardrails and/or personal fall arrest systems (PFAS). Monitor the working area and ensure no hazards or obstacles are in the vicinity of the crane. Aside from maintenance, improper securing of the load or the slings that carry the load is one of the leading causes of accidents with overhead hoists and cranes. Electrocution, electric shock, burns, indirect (e.g., a fall from a ladder), -- Length of exposure to electricity 1. Slings and attachments that arent secured properly can be a major safety hazard, and when objects begin to slip, they will eventually crash to the floor below. -- A Qualified Rigger is responsible for connecting the crane to the material to be hoisted.
