What is the safest method for handling CRTs?

The safest method for handling Cathode Ray Tubes (CRTs) is to discharge them before handling. CRTs can hold a significant electrical charge even after being powered off, which can lead to severe shocks if touched. Discharging the CRT ensures that any stored voltage is released safely, reducing the risk of electric shock and injury to the technician.

Handling CRTs without discharging them—like merely turning them off—does not eliminate the danger because residual voltages can still pose a risk. Leaving CRTs plugged in presents a serious safety hazard as it can lead to accidental energization during the handling process. Covering them with a cloth provides no safety benefit in terms of electrical discharge; it merely obscures the tube and does not mitigate the risks involved when dealing with their high voltages.

By discharging CRTs first, you prioritize safety and ensure a secure environment for yourself and others around you. This practice is essential for anyone working with older electronics that still utilize CRT technology.
