Driver Health & Safety

Mr Waters has a right old whinge on the teev yesterday, and Here about the new-for-2019 coolsuit temperature monitoring forcing him to the pits for repairs.

It makes absolute sense that Supercar did this, to assure the wellness & safety of the driver as their core temperature climbs to unsafe levels, and equally you can understand and Waters’ frustration at being the first to be called in and disadvantaged for what is fundamentally a team preparation error.

The question for me is whether Supercar has gone far enough, if the maximum temperatures selected are actually too high, or whether additional measures of temperature should also be included.

If you saw Mr Davison exit his 23Red car at the end of the race, he must have onboarded half a dozen bottles of ice cold water, and complained of blurred vision, and a lack of concentration during his last stint.

Mr Owen has a similar ‘away with the pixies’ moment back in the Autobarn RNR/ARCA day’s from heat related issues.

The simple answer is to not run in the heat, which makes no sense..
There must be something that could be done to reduce ambient cabin temperatures, and protect the driver from the massive heat infusion from driving the cars, in high or low ambient temperatures.

i disagree with him that it should be a driver choice. the fact that davison continued with blurred vision and struggled to concentrate says that drivers aren't able to make the decision themselves in the heat (no pun) of competition. but otoh, everyone copes with heat differently and has different thresholds.

i assume the cars don't have air conditioning? if not, then maybe that's something that needs to be mandated for future seasons. otherwise they have to look seriously at a maximum temperature/humidity combination.

As above - air conditioning!!!!

Talk of hybrid car this, turbo car that, but the current cars don't even have aircon

So, is the proposed 'Summer Series' really a good idea then?

Surely there could be a refrigerant-driven cool suit system to replace the problematic dry ice ones we have now? Also massively increase airflow through the cabin for hot races; design it in, not just take a window out. A filtered, cooled air system like Baja racers use would help, there were comments about the heat of the air they breathe.

Also after seeing Rick Kelly's piece showing the underside of the car, work could be done on heat insulation to avoid burning feet too.

Did Davison have a cool suit failure, or not get picked up by the new monitoring system?

what exactly is the monitoring system they use at the moment?

Measures the water temp of the cool suit system.. 32.7C is the cutoff, then the driver is required to go to the pits & get the issue corrected.

The catagory mandated a NACA duct in the roof probably 15 or so years ago.

But I agree that more could be done to improve on it.

It's not compulsory for drivers to wear cool suits is it? I recall Lowndes saying he and Richo didn't use them in the Supercheap 1000 last year?

Mr Golding mentioned overnight that he was cramping up at the end of his stint as well, hydration and temperature the likely causes.

A driver is unlikely to take themselves out of the game, as we saw with Mr Reynolds last year at Bathurst.

It's compulsory if the temperature is forecast to be above a certain level. Can't remember what the temperature has to be but I think it's somewhere around 32°C

It has always puzzled me:
  • Why they don't use lightweight flame retardant insulation on the floors and roof. It isnt rocket science, yet NASA had some very light materials on the outisde of the shuttle....
  • The coolsuit system must have some weight associated with it. So surely, put in aircon in its place. Combine that with insulation and off you go.
If you are worried about weight, everyone would be in the same boat if it is mandated.

There are systems available that blow chilled air into the helmet and cool the coolsuit with a refrigeration system. Not sure why they aren't used, perhaps they draw too much power?

Didn't Paul Morris develop a refrigerant AC system many years ago?
