Okay, this isn’t exactly infosec-related, but it was a winner on fedi and I figured the readership might at least find this amusing. It’s kinda like a Murphy’s Laws of heavy industry (as I was an operations & maintenance technician in a past life). The featured image is an example of #8 (that switch is 15 feet up a wall and it’s the safety cutoff for the chain hoist that lifts enormous blower blocks off the floor – if you need it, you can’t reach it, and if you can reach it, you don’t need it – and an engineer put it there). Here’s the expanded version:
– Structural steel is not supposed to feel spongy.
– There is such a thing as load-bearing rust.
-The more hazardous the substance, the less likely it is to be properly labeled.
– The grease you have a 40 gallon drum of is always for a non-critical piece of equipment that only needs to be greased once a year. The grease you have a single half-empty tube of is the kind you need for half the equipment in the facility. They are NEVER compatible.
– If you ever have to check the manual for the “never-exceed” operating parameters, they’re always slightly below the current operating parameters.
– The likelihood of having a particular replacement part on hand is inversely proportional to how critical the part is to the equipment’s functionality.
– There is a right tool for every job. The wrong tool is a crescent wrench (also known as a “knuckle-seeking nut fucker”).
– Never send an engineer to do a technician’s job.
-If the manual says it’s supposed to be “hand tight”, the required torque is always slightly more than the maximum you can apply manually and slightly less than the minimum you can apply with a rattlegun.
– If it doesn’t move and it’s supposed to, grease it. If it’s not supposed to move and it does, put a wrench on it.
– If a piece of equipment has an intermittent fault, the fault will only occur when nobody is looking at it.
– If all else fails, hit it with a pipe wrench.
And most importantly:
– Do not, UNDER ANY CIRCUMSTANCES, wash a Navy chief’s coffee cup.
