7.2 Working safely at the bench

Outcome 2 of 4 in domain 7 · Safety

Power off, verify, one hand, charged capacitors, solder fumes, eye protection.

My targets

I declare:

Discharge a power capacitor before touching it, and measure that it is.
Work one-handed on a circuit at dangerous voltage and explain why.
Ventilate solder fumes, protect your eyes when clipping leads, and park the iron so you don’t put your hand on it.
Verify "power off" in the right order: test the tester, test the circuit, retest the tester.
Protect components from static electricity: strap, mat, bags, and say which chips are sensitive to it.
Read the safety markings on an appliance or charger (CSA, cUL, CE) and know what they guarantee and don’t.
Diagnosis: a circuit that arced when plugged in, the input capacitor; the precharge or resistor that avoids it.
