In the last five years in NSW, 10 workers have been killed and over 2000 workers have been injured in incidents involving mobile plant, across various industries. 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. 10. Provide instruction or guidance to crew members on proper handling techniques. Visual impairment, two-blocking, slipping, mechanical failure, or operator incompetency can all result in serious injuries or fatalities. 6. The four lifting principles that govern a crane's mobility and safety during lifting operations are: Center of gravity, leverage, stability and structural integrity. 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. There are distinct types of mechanized access platforms and the individual types may also be known as a "cherry . 7. Operators and controllers must maintain 100 percent focus on the task at hand to avoid potentially dangerous situations. 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. The competent person determines that it is safe to do so and implements measures necessary to restrain the boom hoist and telescoping, load, swing, and outrigger or stabilizer functions. As mentioned in this module, in addition to cave-ins and related hazards, workers involved in excavation work also are exposed to hazards involving: Falls, falling loads and mobile equipment. Work in harsh weather or strong sunlight may cause health problems. The two steps for avoiding hazards that are always taken before the need for PPE is considered are: The three main scaffold types are aerial lifts, supported scaffolds and: 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: -- Be placed on a firm foundation and be uniformly level within 1 percent of level grade.
