The ethanol component of E85 is denatured to prevent consumption. LPG should be odorized and detectors are recommended to help detect leaks or spills. The fuel is extremely volatile and LPG fires burn twice as hot as gasoline fires. M85 Methanol is corrosive to several metals, rubberized components, gaskets, and seals. Low flame luminosity makes M85 fires difficult to detect in the daylight.
Unhealthy exposure can occur through fume inhalation, ingestion, or direct contact with skin.
Electricity Electrical circuits are self-contained and grounded to limit the risk of shock from the vehicle frame. EV battery packs store enough energy to produce a dangerous or even lethal shock. Electrolytes in the battery may cause chemical burns and protective gear must be worn.
