H2S inhalation inside a car and in a forest

[golfmavenice]

Ingredients:
Lime sulfur(%28)
Hydrochloric acid(%32)

120 mL of each product will produce 1000 ppm hydrogen sulfide. If we have 1 liters of each product it is going to be very reliable. Will probably produce 10000 ppm hydrogen sulfide
I will do this inside a car. In a forest that no one can see me. And put warning signs to every side of my car.

Any advices?

Thanks
