Medical waste rules in Philadelphia, PA
Pennsylvania regulates regulated medical waste and chemotherapeutic waste through the Department of Environmental Protection (DEP) under 25 Pa. Code Chapter 284, part of the Solid Waste Management Act. The chapter licenses transporters, sets a 30-day storage clock at the generator and uses 220 pounds a month as the line below which a practice may move its own waste.
- Segregation and colour (§ 284.411): regulated medical waste, pathological waste and chemotherapeutic waste are separated at the point of origin into their own containers. Medical and pathological waste bags are fluorescent orange, orange-red or red; chemotherapeutic waste bags are yellow.
- Containers (§ 284.413): leakproof on the sides and bottom, impervious to moisture and strong enough not to puncture, tear or burst. Used sharps go in rigid, tightly lidded, puncture-resistant containers; fluids over 20 cc in break-resistant, tightly lidded or stoppered containers.
- Marking (§ 284.414): the outermost container shows the words regulated medical waste or chemotherapeutic waste, the universal biohazard symbol and the word BIOHAZARD, the date the container was filled or sealed and, for off-site transport, the generator's name, address and telephone number.
- Storage (§§ 284.412, 284.415): no more than 30 days from the date the container is filled or sealed; waste that turns putrescent is removed within three business days, and refrigeration at 45°F (7°C) or below, or freezing at 0°F (-18°C) or below, is used when needed to keep it non-putrescent.
- Transporters (§ 284.602): regulated medical or chemotherapeutic waste moves only with a transporter licensed by the DEP. A generator of less than 220 pounds a month may carry its own waste if it keeps the shipping papers; in transit, unrefrigerated waste may travel for up to 72 hours and refrigerated waste for up to five days (§ 284.512).
- Tracking (§§ 284.701 to 284.714): every off-site shipment carries a log or shipping paper with the generator, the licensed transporter, the container count, the quantity and a signature. Records are kept for at least two years, and a generator that has not received delivery confirmation within 30 days reports it to the DEP.
