Machine Guarding Safety

Moving / rotating mechanical parts have many dangers. These may include the movement of rotational members, reciprocating arms, moving belts, inter meshing gears, cutting teeth and all impact or shear parts. Safeguard is a solution or combination of solutions that eliminate the risk of exposure to dangerous moving parts or other harmful conditions and that prevent injury.

Machine Guarding Safety

Dangerous moving parts in these three basic areas need safeguarding

Operation Point: is the area where work is performed on a material, such as cutting, shaping, boring or forming of material.

Power transmission device: is the area of ​​the mechanical system that transmits energy to the parts of the machine performing the work. These components include flywheels, pulleys, belts, connecting rods, connecting rods, couplings, cams, pins, chains, cranks and gears.

Other moving parts: includes all parts of a machine that move while the machine is running. These parts can be rotating, reciprocating or transverse. As well as feed mechanisms and auxiliary parts of the machine.

These machines and objects are presented in their unguarded state to show the danger zone.

Requirements for safeguards:

Prevent contact: The guard should prevent hands, arms, and any other part of the operator's body from coming into contact with dangerous moving parts. A good protection system eliminates the possibility of the operator or other worker placing parts of their body near dangerous moving parts.

Secure: Operators should not be able to easily delete or alter the backup because a backup that can easily be made ineffective is by no means a backup. Protections and safety devices must be made of a durable material resistant to normal conditions of use. The must be securely attached to the machine.

Protect falling objects: the protection must ensure that no objects can fall into moving parts. A small tool dropped into a bike machine could easily become a projectile that could hit and hurt someone.

Do not create any new danger: a backup goes against its purpose if it creates a hazard such as a shear point, a shredded edge, or an unfinished surface that can cause a laceration. The edge of the protectors, for example, should be rolled or bolted to remove sharp edges.

does not create interference: Any backup that prevents an operator from doing the job quickly and comfortably may soon be canceled or ignored. Good protection can actually improve efficiency because it dispels operators' fears of injury.

Allow safe lubrication: if possible, workers should be able to lubricate the machine without removing the guards. Placing the oil tanks outside the guards, with a line leading to the lubrication point, will reduce the need for the operator or maintenance operator to enter the hazardous compartment. region.

Machine guarding Do's:

* Make sure only authorized personnel can remove the fastener from the guards.

* Guards must be designed so that they do not have to be removed during machine repairs or adjustments.

* Make sure the opening between the guards and the machines is minimal to prevent the operator's body parts from reaching the danger point.

* Make sure all start or stop commands should be easily accessible. The emergency stop must be accessible and clearly identified. To restart a machine, always ask for a manual restart.

* Inspection, overhaul and preventive maintenance must always be performed. Have a preventive maintenance program including the inspection of all the protections of the machine.

Machine guarding Dont's

* Do not remove the guards

* Do not change the guards

* Do not make anti-lock protections out of order

* If the guards are removed for maintenance, do not start the machine unless the guards are in place.

* Do not let unauthorized persons work on the machine.

* Do not use poorly designed protectors,

* Do not wear rags or jewelry, do not keep long hair.
