Routine procedures, done uninterrupted, or started again, save lives.
Any more, my foot doesn't want to leave the brake pedal until the parking brake is set, truck in first gear if manual. Bad habits, you die hard.
During a storm, I was flying around on a crane taking a tree off a house. My friend, the general contractor was off bidding more work. A groundie, who had never been trained or allowed to move a truck, moved a truck so someone could get out of their driveway. Didn't put it in gear, and the parking brake, one way or another, was not enough. The truck full of chips and BC1250 on the back started to creep down the steep hill, just beyond the very top toward an occupied house at the bottom. Had the groundie not noticed and run around and been able to push the brake, it would have leveled the house.
Yet some people don't understand why there are procedures, and not everyone gets to make independent decisions about things on a worksite. Some people 'just want to help' like that guy that was almost responsible for massive destruction, and possibly death.
Especially during storm work, buildings on fire, and other emergency, high pressure, high consequence situations, training, procedures, and solid decision-making are life-savers.
The firefighter trainee that worked for me for a bit, until he finished his FF training and moved back to Seattle, said that they were training, performing a Left-Hand Sweep (or something like that, where you NEVER take your Left hand off the wall). Trainee #2 took his hand off, and got lost quickly in the black-out conditions. Their air tank alarms were going off (or whatever), and they were about to have to start breathing the "safe for training" artificial smoke. Yikes.
