Task 6: Permit-to-work system

Question 6:  The organization has an effective permit-to-work (PTW) system.       

Why should a PTW be used to help manage this storage tank modification?                                                                                                                                                  

                                                                                                      (Marks-10)     

Note: You should support your answer, where applicable, using relevant information from the scenario.

 

Method of Answering:

1-Introduction: what is PTW system?​

​

2-Body of the answer: why it is necessary for tank modification specifying the importance of PTW ​

​

3-Conclusion

 

 

ANSWER:

A TECHNICAL MEASURE DOCUMENTED CONTROL PROCESS THAT TAKES ACCOUNT OF ALL PREDICTED INTERACTION BETWEEN THE WORKERS, THE ENVIRONMENT, AND THE ASSOCIATED HAZARD CAN BE TERMED AS PERMIT TO WORK. IT DEFINES THE SEQUENCE OF WORK DETERMINING THE PROCEDURE AND PRECAUTION TO CONTROL HAZARD AND MAJOR ACCIDENT. ​

THE PROPOSED TANK MODIFICATION IS NON ROUTINE WHICH HAS TO BE CARRIED OUT WITHOUT THE SHUT DOWN OF PROCESS AND A COMPETENT CONTRACTOR IS ASSIGNED TO PERFORM THIS TASK. THIS MODIFICATION SHALL BE CARRIED WITHOUT ANY INCIDENT AND SAFELY.​

THE RISK INVOLVED IN THE PROPOSED TECHNOLOGY OF TANK MODIFICATION IS VERY HIGH DUE TO THE PRESENCE OF TOXIC CHEMICAL SUBSTANCE THE RELEASE OF WHICH WILL BE DISASTER TO THE WORKERS NEAR BY RESIDENTS, SCHOOLS AND BUSINESSES.​

THIS TECHNOLOGY IS SAFE AND USED WORLDWIDE IF DONE WITH PROPER CARE AND IMPLEMENTING THE EXISTING AND ADDITIONAL CONTROL MEASURES SUCH AS SSOW, PTW, SUITABLE INDUCTION TRAINING AND SUPPLEMENTARY EMERGENCY ARRANGEMENTS. 

THE MOST CHALLENGING TASK IS TO MANAGING CONTRACTOR AT SITE ESPECIALLY IN THIS CASE WHERE THE RISK MITIGATION CAN BE DONE ONLY THROUGH IMPOSING PTW SYSTEM. ​

THE PTW SYSTEM WILL INCLUDE THE EXPLANATION OF ASSOCIATED RISK ASSESSMENT, CHANGES MADE IN PLANT FOR THE SAFETY PURPOSE, AND ENLISTED ALL NECESSARY PRECAUTION ON PTW FOR THE DESIRED NON ROUTINE TANK MODIFICATION.  ​

PTW SYSTEM WILL ALSO INVOLVE A PHYSICAL CHECK ON THE CONTRACTOR IN TERMS OF AWARENESS OF ASSOCIATED RISK, WORK METHODOLOGY, THEIR COMPETENCY AND APPROPRIATE USE OF SPECIFIED PPE. PTW ALSO EXPLAINS TO BE ENFORCED ALONG WITH OTHER SITE ACTIVITIES BY THE METHOD OF ACTIVE MONITORING IN ORDER TO THE ENSURE THE WORK PROGRESS WITH COMPLETE SAFETY.  THE CONTINUOUS SITE SUPERVISION AND MONITORING WILL ALSO HELP ON CHECKING THE EFFECTIVENESS OF PTW SYSTEM AND RESOLUTION ON THE QUERIES WILL ALSO BE PROVIDED BY THE PROCESS OPERATOR AND INDEPENDENT SITE CONTACT. ​

THEREFORE THE IMPLEMENTATION OF PTW SYSTEM FOR THE TANK MODIFICATION TASK IS IMPORTANT AND IMPOSED IN ORDER TO CARRY OUT HIGH RISK ASSOCIATED WORK SAFELY.
