The Ten Commandments of Electrical Safety
1) Beware of lightning that lurketh in an undischarged capacitor lest it cause thee to bounce upon thy buttocks in a most embarrassing manner.
2) Cause thou the switch that supplieth large quantities of juice to be opened and thusly tagged, that thy days may be long on this earth.
3) Prove to thyself that all circuits that radiateth and upon which thou worketh are grounded and thusly tagged, lest they lift thee to a radio frequency potential and causeth thee to make like a radiator, too.
4) Tarry thou not amongst those fools that engage in intentional shocks, for they are not long for this world and are surely unbelievers.
5) Take care thou useth the proper method when thou taketh the measures of high voltage circuits so that thou dost not incinerate both thee and thy testmeter, for verily, though thou hast no stocknumber and may not be identified, thy testmeter has one and as a consequence will bringeth much woe unto the supply clerk.
6) Take care thou tamperest not with interlocks and safety devices, for this incurreth the wrath of thy supervisor and bringeth the fury of the Safety Department upon his head.
7) Work thou not on energized equipment for if thou dost so, thy colleagues will surely gather around thy grave shortly after.
8) Verily I say unto thee: never service equipment alone, for electrical cooking is a slow process and thou might sizzle for hours on end before thy Maker sees fit to end thy misery and drag thee into His fold.
9) Trifle thee not with radioactive tubes and like substances, lest thou commence to glow in the dark like a firefly and thy spouse be frustrated and have no further use for thee except to pay thy wages.
10) Thou shalt not make unauthorized modifications to equipment, but thou shall cause to be recorded all technical directives and authorized changes made by thee, lest thy successor rend his hair and go mad in his attempt to work out the tangled spaghetti in the wiring.
