An Invercargill businessman died from carbon monoxide poisoning while on a boat trip, a coroner has ruled.<\/p>\n
Richard Charles Murrell, 60, was sleeping on his boat, Fishin\u2019 On, at Lake Manapouri on July 19 last year.<\/p>\n
The boat was found by police on July 21 and Mr Murrell was dead, and further investigation found a generator and diesel heater were being used aboard.<\/p>\n
His friend Scott Allison was found confused and unwell, but survived.<\/p>\n
Coroner Heather McKenzie last month ruled carbon monoxide toxicity, exacerbated by his heart disease and alcohol use, caused Mr Murrell\u2019s death.<\/p>\n
On July 19, Mr Murrell and Mr Allison set off on their trip.<\/p>\n
They planned to travel from Lake Manapouri Boat Club and stay at the Freeman Hut.<\/p>\n
But when they arrived, there were already people at the hut, so the pair decided to sleep on the boat.<\/p>\n
The coroner noted they had never done this before, but had done plenty of overnight trips staying in huts.<\/p>\n
A new diesel heater had been installed on the boat two days prior.<\/p>\n
They cooked dinner using a portable grill and used a petrol generator to power Starlink (used to connect to internet via satellites) so they could stream a rugby game.<\/p>\n
The diesel heater was running but they turned it off before going to bed between 10pm and 10.30pm.<\/p>\n
But sometime later Mr Murrell turned the heater back on.<\/p>\n
\u201cThe next thing Mr Allison remembers is a man, now known to have been from the Fiordland Marine Search and Rescue Team, banging on the boat telling him to get onto the deck,\u201d the coroner\u2019s decision said.<\/p>\n
\u201cMr Allison felt very groggy but managed to get up and tried to revive Mr Murrell but could not.\u201d<\/p>\n
Mr Allison\u2019s wife had called police when her husband did not return home on the afternoon of July 20 as expected.<\/p>\n
At about 1am on July 21, a rescue helicopter crew found the boat in Safe Cove.<\/p>\n
Mr Allison was taken to Southland Hospital.<\/p>\n
The boat was later taken to Manapouri by police where Mr Murrell’s body was recovered and the generator was found switched on and empty.<\/p>\n
A post-mortem examination found Mr Murrell died from carbon monoxide toxicity – although the levels in blood would not usually be fatal.<\/p>\n
The forensic pathologist explained Mr Murrell\u2019s heart disease and the alcohol in his system made him more susceptible to carbon monoxide poisoning.<\/p>\n
A police investigation found exhaust fumes from the generator travelled into the cabin where the men were sleeping via a hole for wires.<\/p>\n
\u201cTesting indicated that the diesel heater did not contribute substantially to carbon monoxide levels inside the cabin,\u201d the decision said.<\/p>\n
Maritime New Zealand said testing results indicated using the diesel heater might have created a vacuum that drew in air from outside the cabin to replace the internal cabin air.\u00a0<\/p>\n
\u201cThis was on the basis that simultaneously running the diesel heater and the petrol generator on the deck combined to produce fatal [carbon monoxide] levels within 3.5 hours,\u201d the decision said.<\/p>\n
\u201cRunning the diesel heater only or the petrol generator only did not significantly increase [carbon monoxide] levels.\u201d<\/p>\n
Although they were not required, Maritime NZ recommended the installation of carbon monoxide detectors on vessels with enclosed accommodation spaces and diesel heaters.<\/p>\n
It also suggested education around the dangers of carbon monoxide emissions from generators on vessels and \u201cinstallers of diesel heaters should be aware of possible dangers of operating a diesel heater at the same time as a fuel burning device such as a portable\u00a0generator\u201d.<\/p>\n
The coroner endorsed Maritime NZ’s recommendations.<\/p>\n","protected":false},"excerpt":{"rendered":"An Invercargill businessman died from carbon monoxide poisoning while on a boat trip, a coroner has ruled.
