Years ago, we had a HelioCurrier Pilot, that flew backwards in a 45 MPH wind, while landing on our Airstrip.... and once when I was out at Cold Bay, Alaska, I saw a Reeve Aleutian Airways YS11 take off going Straight Up while staying completely horizontal, in a 60 Knot breeze...
I posted this for somebody here who was having trouble getting campfire soot off her percolator, but she hasn't been along yet.
A wise Powderman doesn't cut the Shorting Clips, until after he has completed the wiring for the Shot, clear back to the Blasting Machine and doing the initial Circuit Testing.... At which point all Static Discharges are shorted to ground, by the Shorting Clips...
Agreed....however, human error, haste, hubris, and fatigue have seen many a human hand mangled. Best safe practice ought be the goal of every powderperson / shotfirer.... I was taught by a military instructor how to construct ringmains and explosive demolitions when I was attending an assault pioneer course. He had three fingers missing on his left hand, which didn't imbue much confidence in the students, but a lot of respect for the power of detonators.
I was in the Biz all thru College, plus the next Decade, and Apprenticed with a Powder-man with 55 Years of experience in the Demolition Field, during my High School years.... I enjoyed the Math involved in designing the Shot, and then seeing the results... I still have ALL my FINGERS, although I am NOW missing five Toes on my right foot, but not due to a design failure of a shot... or the use of energetic materials...
Got an old Quick-lite lantern that won't turn off? Sometimes the valve just won't shut off all the fuel. Since the pick-up is at the bottom of the fount, inverting it will cause it to run out of fuel. (With Instant-lite pickup it'll work with valve all the way open.) Just remember to close the valve once the last of the fire is out.
