Notes from a safety training course I took online at work, and was told by my boss that I was expected to not spend my time on those sorts of things.

100 - 200 ma Ventricular Fibrillation (possible cns damage)
200 ma + Burns

10v wet or conductive danger voltage
30vac/50vdc dry danger voltage

90 day - limit on extension cord use for portable equip
key terms: energized, exposed, "work on"

De-energize before work - includes power, caps, and potential energy of springs, pneumatics, pressure, and hydraulics.
don't do if it's more dangerous, or because of design limits
Lockout Block (LO/BO) - block energy from equip for maint
Auth by dept manager
lockout adapter - allows multiple locks for multiple workers
keeps one person from hurting another
only you and your manager have your lockout key
never share your key or leave it anywhere.
department lock - everyone has a key
lock - physical restrictor, whether padlock, or other, which is keyed
when in use, should be labeled with "DANGER" and name/contact info
block - prevents dies, lifts or other equip from moving if accidentally energized
also, plugs or blinds in pipes or ducts
tags - 4 types - required for any lockout

Safety - must be authorized AND competent before working on live circuits
use task lighting when needed
use safety/protective equipment as appropriate (gloves, insulated mats, etc)
use gfci when approptiate (outside, panel service, wet, ungrounded circuitry or when potential for your body to short circuit to ground)
no jewelery or metal objects
know where the EPO or main disconnect is.
always have someone with you when working with live, exposed or hazardous voltages
they must know how to de-energize, provide CPR and call for help.
work one handed and don't touch any ground
if not alert, don't work
wear non-conductive safety glasses
