Timeline death of paul mcguire anglo american

The Coronial inquest into the death of mine electrician Paul McGuire is underway at Mackay Magistrate’s Court. AMSJ has prepared a developing timeline of events leading up to the moment when Paul opened a hatch and was asphyxiated. We stress that information is developing and may change accordingly as additional information comes to hand.

Unspecified time prior to the incident

Anglo American completes risk assessments for goaf seal areas

Anglo Amercan Grasstree Mine identifies risk of asphyxiation during risk assessment process for sealing goaf areas. Former Ventilation Officer Shannon Coppard said that that the risk assessment completed on a sealing activity did not identify the possibility of a mine worker opening a hatch and being overcome by an irrespirable atmosphere. Mr Coppard said that “because of controls in place, it was considered a minor risk” Read more A previous risk assessment document ‘807 sealing document’ was used as a basis for the assessment. A design change was also made in the new 901 tailgate seal to incorporate a hatch.

Preliminary discussions regarding calibration

On 5 May 2014, the Outbye Engineering Co-ordinator at the mine had a discussion with Mr McGuire in
relation to the scheduled calibrations of gas sensors. In order for the mine to maintain statutory compliance, the calibrations of gas sensors were required to be
completed by 6 May 2014. On the 6th May 2014 the longwall was on a scheduled shutdown for maintenance and was due to be online at 4.30 pm. The Outbye Electrical Co-ordinator told Mr McGuire that he was to
complete the task the next day but he was not informed of the order of the tasks to be completed or, that a job card had not been amended to reflect the disconnection of a sensor in the goaf.

Grasstree Mine Day Shift Commence

The day shift of 6 May 2014 commenced at 6.00am with a Mine Senior Official (MSO) briefing meeting. During the meeting, the Outbye ERZ Controller was requested to conduct a statutory inspection of the 901 tailgate so that an electrician could access the area to complete calibration work. He was not provided with a job card.

Outbye ERZ Controller completes inspection

The Outbye ERZ Controller completed the inspection of 901 tailgate area at 6.50am and noted this
time with his initials on the 19a cut through A-B Heading man door. It was a statutory requirement that
return airways be inspected and that the inspection approval would remain valid for 6 hours. The ERZ Controller was not provided with a job card. On some occasions he was shown the job cards and others he wasn’t. The no road tape was not in the door in the morning
The inspection boards are at the entry to a particular area, there was no such board for the 901
tailgate, as a result he wrote his inspection notes on the door.

06.50 am, 6th May 2014
7.00 am, 6th May 2014

MSO Handover from nightshift

The handover from the night shift MSO to the day shift MSO was conducted at 7.00am. No discussion
was held regarding the calibration of 901 tailgate gas monitoring detectors. The task to calibrate the
901 tailgate gas monitoring detectors was not documented in the mine’s 24 hour plan which had been
compiled on the previous day but was included on a job card given to Paul McGuire.

Paul arrives on-site at Anglo Grasstree underground coal mine

On 6 May 2014 Mr McGuire was rostered on the afternoon shift. He arrived onsite at approximately
11.15am. It was a maintenance day at the mine, meaning that the Longwall was not producing that
day so that various maintenance tasks could be performed.

11.15 am, 6th May 2014
Approximately 11.30 am, 6th May 2014

Pre-shift Briefing

Mr McGuire attended the pre-shift briefing and collected the Job Cards for his scheduled tasks for the shift. This included Job Card 00913709, which incorrectly identified station 5 channel 7 sensor as being located at 6-7 cut through B Heading 901 tailgate. In fact the sensor was no longer at that
location; it had been disabled and was no longer in use but the job recording system had not reflected changes and the Outbye Engineering Co-ordinator did not check the card in entirety before leaving it for Paul to pick up. The location identified on the Job Card – 6-7 cut through B Heading 901 tailgate – was by that time located in a goaf and disconnected.

Pressure to get the job done

The Longwall was to come back on line after the maintenance day at 4.30 pm and an uncalibrated sensor would have meant that the longwall may have been taken off line. This meant production bonuses would not have been achieved.

Arrival at Pit Bottom

Paul McGuire travels underground and arrives at pit bottom.

Places sensor control unit in calibration mode

The walks toward the 901 Seal. There is reportdely No Raod tape in the area. The ‘no road tape’ is not reflective nor fluorescent.

Estimated 1.03 pm, 6th May 2014

Opens hatch in seal

At approximately 1.05pm, Mr McGuire opened the hatch at 0-1 cut through B Heading 901 tailgate by
using a spanner to access the sensor. The hatch had been closed with a single nut and bolt arrangement. It was not secured with locking devices and only remained barricaded with ‘no road’ tape.

2.00 pm, 6th May 2014

Staff go underground to investigate the alarm

A mine electrical engineer (Scott Adams) goes underground to check what was believed to be a ‘gas sensor problem’. Using a handheld gas monitor he checks levels, recalibrates and replaces a sensor then waits 20 min before raising alarm that the sensors are working fine and the gas concentrations are ‘real’. Fairweather (Mines Supervising Officer (MSO) and Zerner (Fmr Ventilation Officer) then travel underground. “You could see the door was open like a small tunnel and the goaf gas was coming out,” Mr Fairweather said. He added they struggled to open a door to the goaf due to pressure differences. The pair also had to ensure they ventilated the area appropriately. “I opened the door and Garth grabbed a disused pallet nearby,I opened and cracked the door and Garth got the pallet around and shoved it into the door so it was wedged open.

2:50 pm, 6th May 2014

Body of miner found

Fairweather and Zerner find Paul’s body and call emergency Mine Staff attempt CPR and made an emergency call just after 3 pm. He was found with his right calf in the door. He was reportedly transferred to the surface where attempts to revive him were unsuccessful.

Anglo American implements changes to system

Anglo American Grasstree mine implements changes to lock out goaf seal hatches. Reviews accident and makes radical changes in procedures including the use of ERZ controllers in Goafs. The more significant changes that have been made across Anglo mines through working groups include Hard barriers, Signs on the door, Redesigns of the hatches for the lock, barricading with steel mesh and acro props. There has also been a change in the job card and work order process.
Calibration training:electricians are now trained to a competency and Australian standard specifically in gas calibration and hazardous areas. Occurs every two months and competencies are tracked and if they do not require it they cannot carry out the calibration.

Job cards are now required to be scheduled for 3 weeks in advance of when they are needed. The job cards have the old location attached on the back. There is now a system with many quality control checks including the electrician and the ERZ controller are then to validate the attachments to job cards.

Mine Safety Alert 304 is issued highlighting a “Fatal accident in an irrespirable atmosphere” The alert highlights a fatal accident occurred at an underground coal mine when a coal mine worker appears to have been overcome by an irrespirable atmosphere. It also highlights the other incidents involved:
• an ERZ Controller entered an area of a mine while it was being inertised with boiler gas;
• a senior official and a ventilation officer investigated a fixed gas monitor alarm by walking towards increasing levels of gas while their personal gas monitors were also alarming.

Job Card sends another worker to goaf

Another mineworker was sent to a goaf on a job card despite processes in place to eliminate the accident. The worker did not attend but alerted the site.
