Employees working around overhead cranes should always wear proper head, foot, hand, and eye protection. Crane operation safety is the result of effective teamwork among operators, riggers, and crane walkers. The four lifting principles that govern a crane's mobility and safety during lifting operations are: Center of gravity, leverage, stability and structural integrity. Keep an accurate record of operations and maintenance logs. Acute silicosis occurs after a few months or as long as 2 years following exposures to ________ concentrations of respirable crystalline silica. 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 Ensure that all personnel involved in the operation understand and follow safety protocols. 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. Significant requirements in the new crane standard include: All hazards involved in the use of power tools can be prevented by following five basic safety rules: Keep all tools in good condition with regular maintenance; examine each tool for damage before use; operate according to the manufacturer's instructions; provide and use the proper protective equipment; and: Live parts of electric equipment operating at 50 volts or more must be: While any employee is exposed to contact with parts of electric equipment or circuits that have been de-energized, the circuits energizing the parts shall be: The two best means of avoiding electrical shock or injury when working with power tools are: The majority of today's power line accidents occur because: Of failure to maintain proper work distances. Inspect the crane and its components before each use to ensure that all parts are in good working condition. Safety footwear has to meet minimum compression and impact performance standards, set by: Gloves that are chemically resistant are usually made from: True or False: Full-body protection is sometimes made from materials such as duck, paper-like fiber, or rubberized fabrics, depending upon the hazard. If the load or sling holding the load isnt properly secured, the objects can slip out, tip, and eventually crash to the ground below. Provide guards on power tools and other equipment with moving parts (Your Answer). This scaffold is simply a rope attached to a harness with an assembly like a boatswain's chair for the worker to sit in. 1. Overall, most crane safety programs outline competent personnel requirements, and its a good idea to become familiar with them. Truck-mounted and rough terrain cranes are both forms of a mobile crane, and both use which of the following to increase their stability? They are allowed to operate cranes to do maintenance work, to do an inspection, or to verify that the crane is working properly. -- under cranes 6. The crane operator and any workers below should also be aware of his/her surroundings and never walk under a lift. According to OSHA, 80 percent of all crane upsets and structural failures can be attributed to exceeding the cranes operational capacity. When manually moving materials, employees should always try to lift it alone if a load is so bulky it cannot be properly grasped or lifted, when they cannot see around or over it, or when a load cannot be safely handled. Occupational Safety & Health Administration. Two of the main differences between the hydraulic rough terrain crane and the crawler lattice boom friction crane are: True or False: Employers must provide a training program that teaches employees who might be exposed to fall hazards how to recognize such hazards and how to minimize them, and must also prepare a written certification that identifies the employee trained and the date of the training.
