Cathode Ray Tubes

Cathode ray tubes (CRTs) are used in television sets, computers and scientific equipment. Lead (Pb) in the form of lead oxide is added to the CRT glass to shield the user from x-rays.

A typical seventeen-inch computer monitor contains over two pounds of lead. Larger CRTs may each contain up to 10 pounds of lead. Lead can be toxic and is regulated as a hazardous waste.

Disposal

CRTs are collected by the Salvage Department. Complete a Material Request Transfer Form (Salvage Form) before transferring any material to Salvage. The Salvage Department determines which CRTs are not longer usable, and transfers them to Waste Management for proper disposal.

Broken CRT

If you break a CRT device, manage the broken glass as a hazardous waste spill.
