Analysing and Preventing the Un-Guarded Polishing Machine Hazards by using Industrial Safety Methodologies
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
The main objective of this work is to ensure the safety for machine operators and also for machines by preventing the hazards causing by un-guarded components. Most of the engineering works needs the manufacturing process with polishing machines or buffers. Polishing machines or buffers are used to polish various types of metallic and non-metallic components. In real life most of these polishing machines are not guarded properly. It creates safety issues related machine and men. Two main safety hazards associated with polishing machines during polishing processes were considered in this project. Un-guarded polishing machine including rotating shafts locating between motor and the polishing wheel and Un-guarded spindle end and nut on the polishing wheel. This analysis is done by using Fault Tree analysis and Job safety analysis. It can be noted that add a permanent cover/guard that encloses the rotating shaft so that it is not accessible. The spindle end and nut can be guarded with a guard similar to the guards used on grinders. The guard must cover the spindle end and nut in the centre of the polishing wheel so that they are not accessible and no projection hazards exist. This guard may come up from the floor or may be attached to the motor or other stationary portion of the machine. Ensure that the guard itself does not create additional hazards and that all other moving parts such as belts and pulleys are fully guarded.
