Hydrogen fluoride can be very damaging to human health. Because of its routine use in older oil refineries, the compound may escape in the event of a natural disaster; it could also escape from pipes or plastic drums. When people are exposed to hydrogen fluoride, the compound enters the skin and tissues of the human body, damaging cells and causing severe burns, breathing issues and organ damage.
