Parts hazardous moving

Use proper machine guards where required to protect from hazardous moving parts. Never remove a guard from a power tool. 

Are safeguards provided for all hazardous moving parts of the machine, including auxiliary parts ... 

The safety valve is normally situated atop the air reservoir. There must be no restriction on all blow-off points. Compressors can be hazardous to work around because they do have moving parts. Ensure that clothing is kept away from belt drives, couplings and exposed shafts. 

Modern equipment is relatively free from mechanical hazards. For instance, there is always a shield covering drive belts so that they cannot catch fingers or clothing. Nevertheless, a prudent planner will still place equipment with moving parts in a location where contact with workers is unlikely. 

INDUSTRIAL SAFETY PROVISIONS. In the design of the APE and associated operational shield, conventional machine design practices are used to protect operators from hazards associated with moving parts. Proper techniques for guarding of hazardous machine areas are used, including the use of interlocks In the control system to prevent movements until certain conditions are satisfied, or to stop movements In emergency situations... 

Normally a guard is installed on a moving part of the machine, which acts as a barrier to prevent the entry of any part of the human body in the hazardous area. It is also possible that a safety device is installed that prevents or interrupts the operation if part of the operator s body is in a hazardous area or requires its withdrawal prior to machine operation. The guard or safety device itself must not constitute a hazard, must be safe, low maintenance, easy-to-use, automatically controlled, or fixed on the machines. There are different types of guards and safety devices available according to the design and demands of machines. 

In addition to the machine guarding, the control system should be interlocked with an electronically monitored failsafe system. The control software should have an awareness of the position and action of all moving parts and measurement devices. Therefore, if an unplanned incident or out-of-protocol action does occur, the system will take action or stop action to minimize the likelihood of additional safety hazards. In some cases, as with system calibration or super user access, graded access levels can be custom-built into the design for specialized and infrequent operations. 

Mechanical hazards—moving vehicles and machines, moving parts of machinery, uncontrolled moving objects, objects and parts with sharp edges or rough surfaces. 

Safety interlocks, common to machinery, provide a means either of preventing operator access to a hazardous area until the hazard is removed or of automatically removing the hazardous condition (i.e., electric shock, moving parts) when access is gained. Safety interlocks have special requirements, such as fail-safe design, positive opening, and nonoverridable type. 

User protection is paramount Warnings are only permitted when no other means are possible and may not take the place of a safe design. For example, a MOVING PARTS WARNING is allowed only when the hazard is directly involved in the production process and there are no other possible options (i.e., guards, interlocks, stop-switch, sensors). Therefore, if a guard or other protection means is possible, it must be employed.
