In this scenario you’ve got to deal with an irritated co-worker and also decipher what’s going on with the malfunctioning pump!
Making sure you’ve taken the proper steps to troubleshoot effectively and safely will be the key to getting through this one.
Testing for absence of voltage - this is probably the number one thing that can increase the overall safety of every organization when it comes to electrical safety. Properly testing for absence of voltage prior to starting maintenance is a must. It involves the use of a voltage detector or digital multimeter and testing each phase-to-phase and phase-to-ground for zero volts.
Resources required for this scenario
The most important tool for any electrical worker and what should also be considered your most important piece of safety equipment!
Test before touch needs to become your new mantra, and with low voltage (less than 750 volts) circuits you must verify phase-to-phase and phase-to-ground is at zero energy.
Never assume a circuit is dead until you’ve proven it with your tester!
A “contractor kit” is really just all the required arc-flash protection in one easily accessible package.
Nowadays, you can get these kits in almost any incident energy rating, but the most common are:
Cat 2 Kit - Arc rating of 8 cal/cm2
Cat 4 Kit - Arc rating of 40 cal/cm2
They should also come with a set of rubber insulated gloves and leather protectors.
