1. Incident at Kanpur (CUGL)
Date of incident: 04.08.2012
Time: 04.30 PM
Entity: CUGL
Location: Panchakki Chouraha, near Mall road, Kanpur.
Description:
A fatal accident took place on 4th August 2012 at CUGL Kanpur, and a project officer died on the spot in the accident. The accident took place at underground DRS at paanchakki chouraha when downstream MDPE commissioning was undertaken on 4th August 2012 at 430 PM.
The underground DRS is provided by the vendor was single stream of capacity 5000 SCMH. The lid of the underground DRS cartridge blew away due to pressurization inside and hit the engineer on his face standing above ground on the side of the pit leading to the casualty.
It is learnt from the investigation that quarter inch outlet vent present inside the cartridge remained open prior to the charging and hence when inlet DRS valve was opened, gas after reduction of pressure from 19 to 4 kg/cm2 got released inside the upper half of the cartridge (which was not designed to handle any pressure) and due to the pressure of released gas the lid of cartridge busted into the pieces and blew away. It was collective failure of the,
Design of DRS,
• which did not have inherent fail safe mechanism to release such vented gases from the cartridge of DRS.
• which could not hold the released gas inside the cartridge. Same could have been designed to handle max pressure in the system.
Vendor’s commissioning team,
• who did not mention of any such requirement on the signed commissioning format provided by them.
CUGL commissioning team,
• who did not adhere to commissioning procedure including venting of the assembly before Gas charging.
Cause:
• DRS Design fault by Vendor: Not a FAILSAFE design.
• Deviation from adopted procedure.
• Unidentified hazardous operation & compromise towards safety by CUGL team. The safety engineer was not called before start of commissioning.
Recommendations: • To be taken up strongly with Vendor for faulty DRS design and to own them the
responsibility.
• DRS to be preferably relocated and replaced by twin stream above ground installation.
• System to be in place to ensure checklist points on commissioning format itself and its compliance.
• System to be in place to ensure use of PPEs • Role clarity and accountability should be fixed to avoid recurrence in future. • Provision of vent line to safer location should be a part of DRS inherent design. • DRS cartridge should be designed to hold max. Pressure in the system. • Necessary statuary approval/standards should be pre‐requisite before installation of
these systems. • Pressure gauges provided inside the cartridge should be with isolation valves. • All the PGs should be visible for noting daily readings without the opening of
cartridge lid. • Quarter inch vents provided inside cartridge should be with double isolation valves
(block and bleed). • Installation should be with properly designed foundations and pedestals.
2. Incident at Mayor Vihar III (IGL)
Date of incident: 02.09.2012
Time: 2100 hrs
Entity: IGL
Location: MAYUR VIHAR III
Description:
At 18:45 Hrs. media flashed news that a person died due to negligence of local police who have setup a barricade/ check post during a routine exercise on road going from Kalayanpuri to Mayur vihar‐1 via Chilla Village. At 19:00 Hrs. local mob from Chilla village attacked police personnel deployed at the police check post. At 19:30 Hrs. station staff was updated by a customer who came for refueling at IFC‐2 CNG station regarding civic disruption. The station was shut down as precautionary measures and information was given to Mktg & Control room. Due to heavy barricading, IGL staff was not able to reach the site, thus telephonic updates started between the station staff and IGL control room staff.
At 20:30 Hrs. mob from Khoda Village went on rampage, taking advantage of the incident & started looting the nearby market. At around 20:30 Hrs. on understanding the criticality of the situation, Station technician isolated all the manually operated gas valves. Meanwhile the station manager collected the cash from all DSMs and secured it in the safe. This activity was completed by 20:45 Hrs. At 21:00 Hrs, Delhi Police personnel asked the station staff to leave the station premises as the crowd started moving closer. Station staff left the IFC‐II station and gathered at IFC‐I CNG station, which is approx. 800 meters away. Few of them remained near the barricades to assess the situation and continuously informed about the sequence of events till the IGL teams reached IFC‐I.
Marketing officers of IGL managed to reach IFC‐I at around 2145. The mob even tried to damage station safe box at IFC‐II, which was carrying a two days cash of around Rs. 11 Lacs, but could not succeed. At around 22:30 Hrs. control room team, fire & safety team could manage to reach to IFC‐II CNG station to take the stock of situation. Simultaneously, Pipeline department managed to close isolation valves as a precautionary measure. At 01:00 Hrs on 3rd Sept’ 2012. after ensuring the complete isolation of the station equipments, the whole team left IFC‐II on
instruction of Delhi Police team as the mob was again approaching the station. The team gathered at IFC‐I CNG station and finally dispersed.
Cause:
• Pilferage/sabotage
• Lack of job knowledge/ awareness.
Recommendations: • Awareness among employees and contract workers by means of case study to be
taken up by respective control rooms for handling such emergency situations efficiently.
• Frequency of training/Drills on emergency handling should be increased. The information system should be improved so that response time can be minimized.
• Since, approach to site locations under such circumstances is difficult, possibility of automation may be explored for remote operations from control rooms.

8. Incident at Dwarka (IGL)
Date of incident: 22.06.2013
Time: 13.00 Hrs
Entity: IGL
Location: Nuovo Apartment, Sec‐10, Dwarka.
Description: • It was admitted by the Engineer In Charge (of G.I. Riser Maintenance) that the job was being
done without any permission or prior intimation to any person in PNG Control Room, G.I. Riser maintenance incharge or his concerned TPI (Third Party Inspector). He also stated that there was no riser maintenance job lined up on dated 22.06.2013. Still the job was carried by the contractor team without intimation and any supervision. However he refused to give any statement in writing.
• Based on the discussion with bystanders at the incident site, it was informed that the incident happened as the rope that was being used by workers broke and the person who was working fell down on the ground and got injured.
• The injured was taken to hospital where he succumbed to injuries.
• The incharge of G.I. Riser maintenance stated that there were four members in the team (including the deceased) working on that day in Nuova apartment for Riser testing and Painting Job.
Observation:
• It was observed that the yellow paint was found spilled on the ground i.e. at the base of the riser and no paint work was found done on riser from top to bottom. This implies that the worker fell down almost from the top of the building, which was 9 storeyed, which was confirmed by the security guard on duty.
Cause: • Based on the available information from site visit, the apparent cause is Equipment (rope)
failure.
• Since the job of ‘painting of riser’ was taken up by the Contractor team without the knowledge/ permission of concerned C/R and TPI, hence the safety precautions, checking of safety equipments & PPE’s could not be done before starting the job, that resulted in use of unapproved/unhealthy safety gadget.
Immediate Actions/Remedial Measures: • Meeting of all contractors, their authorised supervisors was called and all were
instructed to ensure compliance of safety systems at all levels, failure of the same shall lead to strict action as per contractual terms. M/s Shanvi Construction (the contractor who was carrying out work at the aforesaid incident site) was asked to explain for such serious lapse in executing the work and action they are taking to avoid such recurrence.
• Checking of all the safety gadgets, tools & tackles in all areas is carried out.
• Refresher trainings, briefings, case studies, discussions is taken up in Control Rooms, to educate and sensitise the staff.
