A system used to arrest a worker in a fall from a working level that consists of an anchorage, connectors, a body belt or body harness, and may include a lanyard, deceleration device, lifeline, or suitable combinations of these is called a: When no other alternative fall protection has been implemented, the employer shall implement a safety monitoring system. Monitor the cranes operations and provide guidance as needed. Hazards related to this job Specific preventive measures can be seen by clicking on the respective in the third column of the table. A ground-fault circuit interrupter (GFCI) protects workers from shock by: Matching the amount of current going into an electrical device against the amount returning from the device and shutting down power if a ground fault is detected, AEGCP's are implemented on construction sites to oversee. They are allowed to operate cranes to do maintenance work, to do an inspection, or to verify that the crane is working properly. In the case of materials handling, storage, use and disposal, remember that the main hazards are injuries from: -- Improper lifting and carrying Power tools should never be carried by the cord or hose or be yanked from a receptacle by the cord or hose; and cords and hoses should be kept away from: 4. Looking for the perfect fall protection equipment? Be aware of any potential hazards near the work area, and report them to the supervisor immediately. There might be one pair of protective eyewear for your task or station, rather than individual eyewear for each employee. Safety nets must be strong enough to support workers who fall, and must: Have small enough mesh openings that the employee doesn't fall through the net itself (Your Answer).
