Funny and all, until a decade later you get cancer and don't know why. Short list of stuff that is found in a bus and causes problems when lit on fire:
Plastic Components: Seating, paneling, and dashboard controls. Burning these plastics can release a range of toxic compounds, including polycyclic aromatic hydrocarbons (PAHs), dioxins, and furans, many of which are known carcinogens.
Rubber and Synthetic Materials: Tires and other rubber components, when burned, release a variety of hazardous substances. This includes styrene, which is a suspected carcinogen, along with other harmful compounds like butadiene and benzene.
Upholstery and Foam Padding: These materials often contain flame retardants and other chemicals that can release toxic gases and particulates when burned. Certain flame retardants have been linked to cancer.
Paint and Coatings: The exterior and some interior parts of buses are coated with paints and other surface treatments that can release toxic fumes when burned, including volatile organic compounds (VOCs) and heavy metals like lead and chromium, which are carcinogenic.
Engine and Electrical Components: Burning the engine and electrical parts can release a variety of heavy metals and other toxic substances. The engine oil, diesel fuel (if applicable), and other fluids can also release carcinogenic compounds when burned.
My brother was exposed to burn pits in Desert Storm and now he has ALM. Pretty much the same chemicals you'd find when burning a bus.
