Sougata Pal presents the concept of "Look, Listen, Feel" as an effective condition monitoring tool for identifying machine failures and maintenance needs just in time. It involves using visual inspection, listening for abnormal sounds, and feeling for changes in temperature, vibration, flow or other physical characteristics to monitor equipment condition. Safety precautions must be followed, and individuals should be properly certified and skilled before performing these monitoring activities. Regular use of the senses can help operators and maintainers detect issues with equipment early before major damage occurs.

- 1. Look. Listen Feel! Presented by: Sougata Pal
- 2. Look . Listen . Feel! LOOK LISTEN AND FEEL is a condition monitoring activity which improves the reliability of equipment LOOK , LISTEN and FEEL plays an effective condition monitoring tool which identifies just in time the key indicators to machine failures and maintenance requirements. The concept here is to look, listen and feel the machines to know what needs to have service work and when By Sougata Pal
- 3. Essential Safety Precautions for the Look / Listen / Feel Work Wear all essential personal protection equipment prescribed for each installation Individuals must be deployed for such jobs only after successfully being certified in safety aspects and equipment skills. By Sougata Pal
- 5. Good maintenance practices exhort users and maintainers to do a full visual inspection of equipment and systems before they are put into use, each time and every time Clearing all the abnormalities before putting the equipment or systems to use will increase their reliability. Look By Sougata Pal
- 6. Identifying Lock Out Tag Out (LOTO) Conditions: Visual inspection of control (mechanical / electrical) elements will help in identifying the LOTO conditions Look Running equipment or systems: Periodic visual inspection of equipment or systems while in operation is also essential.This could be done manually by visiting each equipment, looking at the equipment as a whole, checking the relevant critical parameters By Sougata Pal
- 8. This is mostly applicable to equipment with rotating elements (motor driven pumps, fans, compressors etc). Loose components or sub elements on the equipment may cause audible rattling noise. If left unattended, these could lead to consequential damages. . Listen By Sougata Pal
- 9. This technique needs some skill and long involvement of the operator or maintainer with the equipment under his or her charge. The operator / maintainer need to develop a skill on what to listen to and on how to identify wrong noise. This comes from experience. On the long run, an operator will be able to make out the change in noise at a motor bearing or a fan air cutting noise due to blade damage. At this point it may be subjective, but a requisition for more precision measurements could be initiated before a major damage occurs Listen By Sougata Pal
- 11. Safety is very important here since the Feel actions are generally done on running equipment. Care should be taken to avoid putting the palm very close to moving parts The Feel gives you some idea on the difference in temperature, non- visual vibration level changes, flow quality (turbulent or otherwise), presence or absence of flow, presence or absence of a liquid in a container or pipe, heaviness or lightness of an item, rigidity or flexibility of an item, speed / velocity changes etc. Feel By Sougata Pal
- 13. The human nose can discriminate difference in smells. For example, the smell of overheated or burning oil in a diesel engine has a very recognizable odour. Heated or burning electric insulation also has a very distinct odour. The smell of a burning flourescent lamp choke is very discernible. Smell of a dead rodent in a ventilation duct can be very disturbing. Smell By Sougata Pal
