The frames and tracks of electrically driven cranes and hoists must be grounded such that "[t]he path to ground from circuits, equipment, and enclosures should be permanent, continuous, and effective," according to OSHA. 29 CFR 1910.304, paragraphs (g) and (g). Effective grounding is also required for personnel who work on or near these devices.
Grounding is particularly important when working with power tools or other electrical equipment because they can be a source of electric shock if not properly connected. To ground these objects, they must be attached to the body or clothing of the worker. For example, a tool belt can be used to meet this requirement.
Cranes are dangerous machines that can cause injury or death if they malfunction or use incorrectly. Therefore, it is important that they are kept in good repair by being tested and inspected regularly by a certified technician.
OSHA also reminds employers that the most recent editions of the National Electrical Code (NEC) include a general restriction on equipment that passes through bridge and trolley wheels. ( Does OSHA have any grandfather-type exemption for overhead cranes and hoists' grounding requirements? Yes. In its final rulemaking for crane-related ground conductors, OSHA stated that it is not adopting a general requirement for all aerial work platforms because existing law already provides sufficient protection for workers using such devices.) The NEC restrictions apply only to equipment used in construction or other industrial activities. For example, an overhead crane used in a warehouse would be within its legal rights to pass electricity through its trolley wheels.
However, when used in construction sites where people are working at elevated locations, such as building roofs or high-tension power lines, overhead cranes need to be grounded. This helps prevent electric shocks from being transmitted through people to the crane operator or others on the ground who might come into contact with the crane's trolley wheels.
Employers must comply with these regulations whether they use their own employees or hire outside contractors. If an employer fails to do so, they could be subject to fines up to $70,000 per violation. Workers may file suit if they believe they have been injured due to an employer's failure to meet these regulations.
Your crane should only be used on flat terrain. Examine any potential overhead risks, such as towering structures that might interfere with electricity lines or work areas. It is best to be extra cautious if there are distractions in the work space. Crane operators must be cautious of potential hazards such as electrocution. Operators should always use caution not to knock objects over that can fall onto people below.
Crane operators must also be aware of their environment. For example, they should never operate a crane near heavy traffic or while distracted. They should take special care not to hit vehicles or other objects with the boom or load of the crane.
Finally, operators must ensure that everyone involved in the operation of the crane has the necessary training and experience. Only individuals who have been trained in its use should operate cranes.
Crane accidents are very common because operators often fail to follow safety procedures. If you are operating a crane, remember these tips to avoid mishaps.
The United States Department of Labor, Occupational Safety and Health Administration (OSHA), particularly includes the operation of mobile cranes on barges as part of its crane and derrick standard for construction activities involving mobile cranes functioning atop barges. Background (Part CC).
In addition, the American National Standards Institute/International Organization for Standardization (ANSI/ISO) provides standards for mobile cranes operating on vessels. These standards are found in ISO 15983-1:2009(E) "Mobile equipment--Determination of minimum safety requirements for use on board ships" and ISO 15873-2:2010(E) "Mobile equipment--Determination of minimum safety requirements for use on board offshore drilling rigs".
Both OSHA and ANSI/ISO state that all maritime workers working near mobile cranes must be trained in their use. In addition, these organizations recommend that various types of protective equipment be used by workers when around mobile cranes.
Barge workers face many of the same risks as other workers on vessels. Therefore, they are usually covered by the same occupational health and safety regulations that apply to other vessel employees. However, since there are no federal laws specifically regulating barge work, most states have enacted their own legislation regarding barge workers' rights and safety precautions.
