Compliance Talk: Lock Out/ Tag Out

compliance-talk-LOTO-center-image

To keep workers safe, it’s important that electronically powered equipment and circuits are de-energized before mechanical work is done.

OHSA R.R.O. 1990 Regulation 854, s. 159 (3) specifically requires that precautions to guard workers against injury by moving or energized parts are taken before maintenance, repair or adjustment work is performed on a machine that is energized.

To help comply with these regulations and ultimately prevent accidents, we suggest miners take the following steps prior to performing electrical work.

1. Determine the location of the energy source for the circuit to be worked on.

2. Carefully de-energize the circuit.

3. Each employee working on the circuit should place his/her own lock and tag on the disconnecting device.

4. Test circuit to be worked on for voltage to ensure no electricity is present.

5. Ground all the phase conductors to the equipment grounding conductor with a jumper.
