RTM - BEFORE you use the machine in your workshop. It might just save you from serious injury.

"RTM - BEFORE you use the machine "
 
What is RTM please? Forgive me if obvious but I am not acronym savvy these days.
 
I remember RTSD was "retire to safe distance" in some mining explosives manuals I saw once. Is it something to do with that?

When undoing chucks, or loosening nuts with a spanner, always look to see what you are going to cut your knuckles on first!
 
I find it best to apply controlled blows with the palm of my hand to the chuck key or spanner so that when the chuck/nut frees it does so in a controlled manner and my knuckles stay intact.
 
Secondly, when using a screwdriver, do not hold the part to be worked on in the hand in such a way that if the screwdriver slips the blade will do youself injury. It seems obvious especially when you're looking in the first aid cabinet for a plaster!

Gentlemen
All very interesting, Clockie, Your hands are precious, they are not hammers, if you want controlled impact use a soft headed hammer held close to the head ( the head of the hammer not yours ), most of all use common sense and think about your actions before carrying out any task says he after asking the lad in our shop to disconnect the power before I start work on the mains side of the board, BANG theres me all a tremble on the other side of the room and him laughing his head off, that is when I used my hand as a hammer, he assumed that just switching off at the socket was enough, he soon learnt that when I said disconnect I meant it. When you have finished with the centre rotating or not remove it from the taper and put it away, not only does it save it from damaging the point it also saves you getting stabbed.

Well I'm sorry Richard, but when I want to work on anything electrical like that, I make damn sure that it's switched off, isolated, dumped and earthed if there's any significant danger from it retaining any sort of charge at all. And if it involves pulling fuses, then they stay in my pocket. To me, common sense dictates that I don't trust anybody to do any of that for me.

From recent experience.
 
Wear really good face protection and strong when changing the blade on a band saw.
 
If you get swarf in your eye, go straight to hospital. If you leave it you have the extra delight of 'rust rings' that also have to be (painfully) removed.

Oops!
 
Wear really good face protection and strong gloves when changing the blade on a band saw.

Thanks, John. I meant to type RTFM, but obviously I'm one letter short of an acronym !
 Yes, Diane - so I did type it correctly, before being "blitzed", sorry, "moderated" !

I was talking about an incident that happened over 30 years ago, and I now do exactly as you do, you cant see or smell electricity but you can certainly feel it, that also goes for hydraulics and pneumatics, immense power stored in a small place ready to trap the unwary or stupid.

Don't get complacent, and Never Ever take your eyes off any moving machinery for a second - especially cutting blades!
And, If you don't need the machine running if you need to move something, Turn it Off!
I speak from scary and very painful recent personal experience.
 
Having ripped down a couple of dozen chestnut spindle blanks on a 12" 3HP table saw, I moved round to the side of the table to pick off the final new blank.
Catching some movement in my peripheral vision, i looked up - it was my wife walking past the open barn door!
For whatever reason (complacency? borne of doing this kind of work for a few decades maybe? ) I carried on picking up the spindle blank and Not Looking where my hand was going - which was actually well to one side of where the blank was sitting!
 
Unfortunately, and God only knows how it happened, because I don't, I shoved my right hand straight into the top side of the 12" TCT cutting blade, which was running at around 3000 RPM.
All I remember of the immediate incident, was a bang and my arm being thrown back behind me, plus a mist of blood spraying everywhere! (which is also unfortunately, what my wife saw)
 
Fortunately the saw guards were down, but the wide kerf on the blade tips had chewed into the end of my right thumb from underneath and up into the nail, from the right nail root to the left side of the tip, bouncing off the bone.
All that was left of the tip was a chunk of nail hanging onto a bit of flesh.
 
I can tell you it was Not a very pleasant sight at all, quite frightening in fact, and the pain was absolutely bloody unbearable for some time!
I got through a Lot of paracodol that first week!.
 
I can no longer feel anything in that thumb tip, and picking up anything small is now difficult, which has virtually screwed me on watch repairs, But, you wouldn't even know I'd pulled that stupid stunt just by looking at the damage.
I do know I was Very damned lucky not to have lost a lot more than I did!.
 
The lesson driven home to me, was that although I'm always very careful with these things (push-sticks always used, hands behind and well clear of the blade, guards in place etc) I didn't Need the saw running at all when that accident happened!

One incident I recall from my motor engineering days, prompted by the 'high pressure in small volumes' comments.
 
A couple of apprentices were pratting around in the lube bay one day, with one berk firing off the air powered grease gun at his chum!
Firing this thing off into open air, would send a fine jet of grease a good 20ft!

Unfortunately, he got a bit too close for comfort on one shot, and the high pressure jet of grease caught the other lad's finger slitting it wide open, stuffing a good wodge of the stuff under the skin where it was ruptured!
Immediate hospital treatment needed due to lithium grease getting well embedded in his flesh.
That wound looked very untidy for quite some time!

Hi
Dont leave the chuck key in the chuck.
With screwed on chucks dont switch into reverse to stop the lathe.
Dont climb mill on a conventional milling machine
ITs been said before dont use a file without an handle.
Always clamp job on drilling M/C
Dont pull swarf with fingers.
Set stop on flypress and you wont hit yourself
