The solution....ventilation. 99% of the issue can be solved due to exposure with good air flow.
The problem is most track are just converted office spaces and are not setup for use of any type of chemicals indoors,,motor spray,paint, tire additives etc.
If racers have a problem they should try to pressure the track owner to properly ventilate the space....maybe even agree to pay an extra 5$ a week to race to offset the costs of changes.
Good luck
