In the case of materials handling, storage, use and disposal, remember that the main hazards are injuries from: -- Improper lifting and carrying 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. True or False: Once a fall protection device has been inspected by a competent person and deemed safe for use by an employee, it is up to the employee to inspect it regularly and ensure that it still meets OSHA requirements. Operators and controllers must maintain 100 percent focus on the task at hand to avoid potentially dangerous situations. One who is capable of identifying existing and predictable hazards in the surroundings, or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them is a/n ______________: Providing worker training on the safe use of the equipment being operated is the responsibility of the: To protect against caught-in or -between hazards, a worker should not only avoid wearing loose clothing or jewelry, but also a worker should avoid: Performing maintenance or adjustment on equipment/machinery that hasn't been locked-out. Truck-mounted and rough terrain cranes are both forms of a mobile crane, and both use which of the following to increase their stability? Electric shock occurs when: Your body becomes part of the circuit OSHA 1926.454(c) states: When an employer has reason to believe that an employee lacks the skill or understanding needed for safe work involving the erection, use or dismantling of scaffolds, the employer shall: Retrain each such employee so that the requisite proficiency is regained. Keep an accurate record of operations and maintenance logs. Usually, the person who is electrocuted is touching the crane when it comes into contact with the power line. Preventing these disasters requires workers to recognize certain hazards that occur during operation and follow safety procedures to avoid them. Monitor the movements of the crane at all times during an operation. The Trustees protect and share the Massachusetts places people love for their "exceptional scenic, historical . Which of the following is an element of a hearing conservation program? They help move heavy items from one place, Read More Factors That May Cause A Forklift Truck To OverturnContinue, An Essex-based builder has today been sentenced after putting three people at risk of carbon monoxide poisoning. Sometimes it looks like the easiest way to put employees where they're needed is to lift a man-basket to the work area. Moving the crane too quickly and jerking the hoist when its bearing a heavy load can be hazardous to the crane operator and workers nearby. At holes, guardrail systems must be set up: 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 objects between top rail and walking surface. 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 (Your Answer). Complete post-operation checks to ensure the crane is in good working order before shutting it down. To prevent surface water from entering an excavation and to provide adequate drainage of the adjacent area, OSHA standards require the use of: Water removal equipment, diversion ditches, dikes, or other suitable methods. Maintain a safe working environment by observing proper lifting techniques and safety rules. 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. Performing a safe lift requires several roles with specific responsibilities. Likewise, suspended loads should never be moved over employees and personnel should never be lifted or transported on a hoist. Gantry cranes (overhead cranes)More favorable for high projects, such as bridge work, as it has a higher lifting capacity, and the larger models can take loads of more than 800 tons and reach over 600 feet. This process is known as: 3. is inherently dangerous.
