09.2 – Verification & Testing
The Critical Importance of Verification of Zero Energy State
Placing systems in a safe working condition might seem simple, but there are several factors to consider.
- Proper planning and preparation will make any type of testing simpler and safer.
- Having to gather (fetch) other tools or testers interrupts focus and can contribute to an accident.
- Will you be troubleshooting or testing for the absence of voltage?
- What test instrument will be used to determine the absence of voltage?
- Is a detailed warning label present for arc flash and shock?
Kindly, pause the audio now, if you’re listening, and play the video below. Then return and continue this audio recording when the video has finished playing.
So what must be considered when testing for zero or absence of energy?
You MUST always treat it as if energy is there until you prove there is not.
ALWAYS.
Ask yourself some primary questions:
- What PPE will be required?
- What is the voltage of the circuit?
- What is the Arc Flash Boundary?
- Is your lockout/tagout complete?
- Is your test tool functioning properly?
