"According to a safety specialist with the Amalgamated Transit Union (ATU), a thick, felt-like layer of human hair, skin, and other debris has collected on the aging tracks of the city’s rails. In particular, hair has built up on insulators supporting the transit system’s electrified third rails, which run cables carrying 750 Volts of electricity to power the trains. The hair coating delivers a real threat of electrical sparks and fire."
"However gross, the collection of hair from riders may not be that surprising. The system provided 97 million rides in 2016. A single healthy person sheds anywhere from 10 to 200 hairs per day. But those with health issues or hair loss can shed far more. Stress—a common problem around DC—can also up the head shedding."
LOL
