Does anyone have any hands-on guidance or recommendations for plant operators sat in what would practically be a 'greenhouse' through solar gain during this prolonged hot spell we are experiencing.  

I appreciate regular breaks, taking in plenty of fluids, opening the window, covering up, rotating the task would be the norm but would it be reasonably practicable to provide additional measures i.e. a fan or similar, additionally would readings from a thermometer within the cab should be the deciding factor if a specific plant related task should cease.

Additionally can plant be operated with the door open to provide the operator with additional ventilation.

Any comments will be greatly appreciated.

In addition, make sure they wear sunscreen? I;m assuming the plant in question doe snot have air con available? Could it be retrofitted?

It is also worth bearing in mind that the plant itself might also struggle to cope with the heat so maintenance programmes should be reviewed to try and avoid engines/radiators from overheating - might help justify allowing more regual breaks for the operatives if you can point out that allowing the machinery to cool down might help prevent long-term downtime?

One other option is to invest in cooling vests/clothing which is available these days eg: https://www.techniche-europe.com/  Not something I've ever tried so can't vouch for the level of effectiveness but hopefully someone else can advise if they are a viable option?
