Atrain near jason’s house just derailed. the local authorities said it is carrying hazardous chemicals and that the local population should evacuate the area. jason walks out on his front porch and doesn’t smell anything unusual so what should jason do?

Jason must evacuate the premises, (himself and all people nearby).

Not all chemicals are odorous, some are odorless and even colorless such as carbon monoxide or even radon.

The train may contain radon. Radon is an alpha emitter.

In high doses, it is carcinogenic in exposed populations, with an excess mortality due to lung cancer that increases linearly with the cumulative exposure of the lung to radon and its descendants.
