Gasoline
Gasoline can cause all sorts of hazardous injuries and accidents. As a material, it is highly flammable, and can easily catch fire. When it comes into contact with skin, it can cause extreme irritation. When splashed in your eyes, it can cause severe eye injury. When ingested, it is highly toxic and can kill you. It’s advisable to purchase only the smallest supply that you need, and be careful not to dispose of leftovers in curbside trash; contact a hazardous/chemical waste company or find a disposal drop-off event near you.
