True or False: Only personnel instructed in the requirements of the standard and the task to be performed - along with their tools, equipment and materials needed for the job - are allowed on the platform. Do not move your load with coworkers around the area. DICA employs a three-step fitting process, including identification of the key data points for the equipment and the maximum outrigger reaction force. To provide a safe environment of work and to ensure compliance with current legislation and relevant Occupational Health and Safety (OH&S) measure crane lifting safety Procedure has been developed and is to be implemented by every member of the bridge construction team involved in lifting operation. 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. If materials are not properly secured, for instance, the load can slip and land on workers in the vicinity or cause major damage to property. Material handling tasks should be designed to minimize _________ of the given activity. The use of cranes on construction sites to lift heavy equipment, building materials, protective systems, erect steel, etc. -- There are exposed electrical hazards.

Move the personnel platform slowly and cautiously and have rotation-resistant rope with a safety factor of 10 Have all brakes and locking devices set when the occupied personnel platform is in stationary position The three main scaffold types are aerial lifts, supported scaffolds and Suspended scaffolds Working Safely Around the Lines. Define the work zone as the area 360 degrees around the crane, up to the crane's maximum working radius. Assign a second employee on the ground to monitor the area, in addition to the worker at height. Thats because the loads being lifted by overhead hoists tend to be fairly heavy and cause serious damage if dropped. In just the last six months, four workers were killed when they were struck by moving plant, while one plant operator was killed when they collided with other mobile plant. The top edge of a guardrail must be from 39 to 45 inches above the walking/working level, and there must also be a means of protection from: Falling between the top rail and the walking surface. Reduce the Chances of Fatalities: Properly outline fall zones with barriers. Crane operation is a complex task that requires a high level of skill and training. Performing regular maintenance ensures the hoist and overhead crane remain in good working order and that all operations run smoothly. Electricity travels in closed circuits, and its normal route is through a conductor. This field is for validation purposes and should be left unchanged. The first step in building a scaffold is to: 3. If you work with dump trucks, bucket trucks, cranes, excavators, backhoes, ladders, or other equipment with a long reach, chances are you are working dangerously close to overhead or underground power lines .

Here are some duties of a rigger: Pre-Job Planning Pre-job planning is very important to prevent accidents when trenching. When mechanical problems do arise, operators should use the lockout/tagout procedure to prevent accidental startup or movement of the crane until the problem has been repaired. In noisy jobsites, these are often used to provide instructions to crane and derrick operators: Since its implementation in 1971, OSHA has: -- Helped cut work-related fatalities nearly in half and cut excavation and trenching fatalities by more than a third If there is no controlling entity, the employer (if there is only one employer operating the multiple pieces of equipment), or employers, must institute such a system. Because using cranes or derricks to hoist personnel poses a serious risk to the employees being lifted, any cranes and derricks that hoist personnel must: 8. 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. Overhead crane manufacturers can work with you to design an electrification system using lightweight beams or a series of poles to keep your electrification off the ground.

Or, portable gantry cranes can be designed with longer extension cords to accommodate power supplies that may not be as close to the work area that the crane is moved to. Using technologies such as load-measuring systems for training and planning can greatly reduce the hazard of overloading and operator incompetency. 3. Exception: When the employer can demonstrate that it is neither feasible to erect such barriers on the ground nor on the equipment, the hazard areas must be clearly marked by a combination of warning signs (such as "Danger--Swing/Crush Zone") and high visibility markings on the equipment that identify the hazard areas. The second method is to roll the load back and forth on the tracks along the bar itself. True or False: There is usually some form of warning before a cave-in. Crane operation safety is the result of effective teamwork among operators, riggers, and crane walkers. crane, elevating work platform or a concrete pumping truck is operating around energised overhead electric lines and associated electrical equipment and the risk . 9.

General safety principles that can help reduce workplace accidents include: 7. 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. unpleasant noise, dust, dirt, or fumes from the work area. This will help create visual clues for workers to ensure that the crane is always positioned so that the boom and hoist line cant intrude in the danger zone. Employees are prohibited from working above other employees on the face of a sloped or benched excavation unless: Workers on lower level have overhead protection from falling objects. Telescopic Crane Then we work with customers in mobile crane safety to determine soil bearing capacity. Manufacturing is located in several facilities in North America and Europe . Inspect rigging equipment before each use to ensure that all components are in good working condition. as the standard pertains to their work. 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. Provide instruction or guidance to crew members on proper handling techniques. According to OSHA, nearly 50 percent of overhead crane accidents are the result of machinery coming into contact with a power source during operation.
