when are safety features unsafe

lots of safety features get in the way and disrupt workflow and are unsafe my hitachi cms has a blade guard that is fine most of the time but once in a while when i am cutting the thickest wood it can cut the blade guard gets in the way without the guard i make the cut and i am done with the guard i have to grab and hold the guard which takes away my concentration of the more important work read an article where a test pilot died in a cirrus recently the cirrus planes all have airframe parachutes glass cockpit and airframe parachute are the two dominant features but it turns out that there have still been quite a few fatalities in the plane and the plane has a higher rate of incidents that similar planes from other plane makers pretty clear that safety features actually provide a false sense of safety where proper training and techniques take a backseat some people should not operate dangerous machinery drive cars fly airplanes

The best one I heard was the mathemetition, the engineer, and the model. The mathmetician sat on the opposite end of the park bench from the model. After a few minutes, he moved half way towards here. A few minutes later, he moved half again the distance towards her. He then got up and went home, figuring that the whole thing was hopeless. He could never reach the mode.

The engineer then sat down where the mathmetician was. He then moved half the distance towards here. A few minutes later he moved half again the distance. The engineer didn't give up, knowing that pretty soon he'd be close enough.

I'd explain what I was doing and invite her to join me. We'd both move half the distance to each other and get the whole thing done in one move. :-)

A man can dream...

She would have already come over to me.

I've a circular saw with a safety switch on the handle - right where I could reach it if my thumb were a half inch longer. Result is that I have to hold the trigger with one hand while pressing the safety interlock with the other hand, while moving the saw guard with the third hand. I'm looking for a new circ saw.

Old thread, but I had a circular saw that the trigger lock was right where the thumb rested.

Trashed it long ago.

Not near as old as some.

I just downloaded 660,000 headers, going back to 2003.

True but it was discussed at length then.

But if you do have any really good ones, let me know. They can be awesome shop tips like Swingman's plywood cart and don't necessarily have to be funny... but it helps.

Just a note of ancient history. When I was an engineer at Enormous Aerospace before it got taken over by More Enormous Aerospace, there was a press that was activated by a foot pedal. The OSHA people made a big deal out of the risk of accidentally actuating the foot pedal and required that a guard be installed to prevent this. The press had been installed during WWII and between then and the time that OSHA got involved there had been no injuries associated with it. In the five years after the guard they demanded was installed there were three injuries caused by the guard, which presented a tripping hazard.

Sounds par for the course.

Friend had the company issue new "safety" razor knives. He's cut himself more times with those things ...

I'd be curious to know if the manual for the saw gives instructions for proper guard adjustment...

as far as the cirrus safety is concerned, a ballistic recovery chute does NOTHING for safety except in the case of catastrophic airframe failure, or possibly engine failure over hostile terrain, and only above a rather significant hight. Deploying the chute at 500 feet isn't going to do much, and having the chute does NOTHING for turn and stall accidents on approach or takeoff, nor for wind shear or wake turbulence issues on takeoff or landing, nor for "controlled flight into terrain". Ditto for engine failure on takeoff. The chute is no substitute for the brains between the pilot's headset. It's also a pretty hot little plane - and the chute is no substitute for flying experience - just like the problem with the "fork tailed doctor / lawyer killer" the Beach Bonanza. Perfectly good high performance plane, but like a lot of fancy cars, owned predominently by those who are too busy making money to become or stay profficient in it's operation
