It was determined that, although the proper Hazardous Energy Control (HEC) was used for the electrical hazards, the HEC requirements for rotating equipment were notDec 01, 2009 · Step 1: Identify the problem points. To identify the problem points in a machine, a basic understanding of mechanical hazards must be understood. The basic types of hazards are presented as motion hazards or action hazards. Examples of motion hazards include rotating (including in-running nip points), reciprocating and transversing. pulley. A pulley is a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim. Pulleys are used singly or in combination to transmit energy and motion. Pulleys with grooved rims are called sheaves. In belt drive, pulleys are affixed to shafts at their axes, and power is transmitted between the shafts by means of endless belts ...Types of Pinch Points. Amputations, lacerations, contusions, crushing of tissues and bones, and fractured bones are examples of pinch point injuries. ... So all moving portions of belt and pulley drives that are seven feet or less above the floor must be protected with safety guards or shields. In this hazard, one or more items move towards ...In-running nip point hazards are caused by the rotating parts on machinery. There are three main types of in-running nips. Parallel rotating parts: Parts can rotate in opposite directions while their axes are parallel to each other. These parts may be in contact producing nip point. Stock fed between the rolls may also produces nip points.Several general types of hazards exist on many types of machinery. Shop and machine users must be provided protection from these hazards. ... or chain. Belts, pulleys, flywheels, rotating parts etc. must be guarded to prevent entanglement and amputations. Older machinery is notorious for not providing this type of guarding. Rules for all Machines.A large proportion of the hazards on moving machinery arise from running nips. A running nip occurs when material runs onto or over a rotating cylinder. Running nips exist, for example, where a belt runs over a pulley wheel, a chain over a sprocket wheel, a conveyor over a roller or material over a drum, or where two rolls create an in-running ... These components include flywheels, pulleys, belts, connecting rods, couplings, cams, spindles, chains, cranks, and gears. Other moving parts: all parts of the machine which move while the machine is working. These can include reciprocating, rotating, and transverse moving parts, as well as feed mechanisms and auxiliary parts of the machine. critical to be applied in various types of work to reduce or even eliminate the potential risk of danger that results in accidents.

It is mainly used to lift a load. Three types of pulleys are used: Fixed Pulley, Movable Pulley, and Compound Pulleys. The ideal mechanical advantage of the pulley system is equal to the number of loops of the rope pulling the load. These different types of hazardous mechanical motions and actions are basic in varying combinations to nearly all machines, and recognizing them is the first step toward protecting workers from the danger they present. The basic types of hazardous mechanical motions and actions are: Motions Rotating In-Running Nip Points Reciprocating TransversingSafety & Hazard Warnings (cont.) Note: A stationary, non-rotating fan does not mean that the fan is isolated from the electrical supply. A non-rotating fan could be subject to controls or other circuit protection devices that may start the fan without notice. The following safety precautions should be followed, where applicable:A nip point is a type of pinch point involving rotating objects, such as gears and pulleys. [2] Injuries can range from minor such as blisters to severe like amputations and fatalities. [3] Examples of pinch point hazards include gaps in closing doors and objects swinging or being lowered near fixed objects.

Describe the potential consequences from the hazard (think about injury, illness and/or property damage) if nothing were done.Another hazard of farm machinery is the pinch point. Pinch points are formed when two rotating objects move together and at least one of them moves in a circle. For example, the point at which a belt runs onto a pulley is a pinch point. Belt drives, chain drives and gear drives are other sources of pinch points in power transmission devices. If the pulley is exposed and easily accessible, that also is a consideration. In the example, the likelihood that the hazard will occur is high because there is no guard preventing contact, and the operation is performed while the machine is running. By following the steps in this example, you can organize your hazard analysis activities. A rotating driver component (Motor) Often there will also be belts and sheaves or pulleys to connect the two and sometimes the fan will be direct-driven and no belts are required. Despite these variations, those are the two things that every industrial fan has in common. Additionally, every fan has the same specific industrial fan safety hazards. Two or more pulleys boxes.
