The Wisconsin Department of Natural Resources' regulation on hazardous waste prohibits businesses and institutions from disposing waste computers in solid waste landfills and incinerators if they exceed toxicity characteristic levels. Relays and switches can contain mercury. As a product, these toxic substances are safely sealed. However, chances of breakage are high when the computer is sent to a landfill. The toxins can eventually find a way into the water supply.
Crushed glass releases lead-bearing particles, thus becoming an airborne hazard.
If improperly managed, human contact with the CRT toxins could be deadly.
