Pillar drill guard (BS4163 fail)

[OldGitEd]

Drill press JDP-2800VS

Informed yesterday that our pillar drills has failed safety inspection as it does not cover the whole of the drill bit as needed in BS 4163. The guard needs to cover the drill bit with no part at the bottom open when used. Guard should rise and fall as drilling is done.

Most guards seem to fit around a collar, but the collar on this drill is very large and we cannot find a suitable guard without breaking the bank or considerable re-engineering to attach.

Is there anyone on here that have some advice. Thanks in advance.

If there is no exposed drill bit then how do you drill holes ? If the guard is clamped round the collar and hides the entire length of the drill then when you wind the drill down, the guard will hit the table or workpiece first !

Did that safety inspector pick up on the potential loose handle with the locknut backed off clearly visable in your photo ?

Not trying to be funny but can you get away with a shorter (stubby) drill bit that will mean the sliding plastic guard is within requirement?

Or fabricate a taller bottom sliding part for the guard. The existing design looks to be sliding but is currently not tall enough.

The guard should be telescopic as the bit goes into the material to be drilled.

Drill is locked off and not able to be used until sorted. The handle is loose as is taken off for photographs now.

This is what we need. Now to find the size for the collar.

……or a shorter drill bit (as per my earlier reply/thought).

Or fabricate a taller bottom sliding part for the guard.

Or fabricate a taller top fixed part for the guard. That might be easier as it has no slotted holes.

In addition, the photo seems to show the top part of the guard is shorter than the bottom face of the chuck. You could only ever drill until the face of the chuck hits the stock, so extending the top part of the guard that far will not have any bad effects.

I worked in a college for 12 years & secondary school for 5 years as a D&T technician, BS4163 was the default document with H&S updates through CLEAPPS. I retired 5 years ago.
This smacks to me of a H&S inspection /inspector going way over zealous, All our Drills had guards but totally enclosing the drill complertely is simply not practical. Im curious who is asking this to be done? Is it the service provider or a maintenance contractor?
We had such a contractor imposed on us by our service provider & frankly they were incompetent charlatans.

The HSE consultants to the men's shed I once attended were equally incompetent.

It's no consolation but drill chuck guards really are a joke, even the good ones from a brand like silvaflame. Look for some way to make a workable compromise : a guard that surrounds the chuck only could fulfill the useful role of ensuring the drill can't be started with the chuck key in and that nothing can snag the chuck jaws. In this regard it's like the guard around a metalwork lathe chuck (similar mandatory).
The bigger hazard is that the work (especially thin metal) gets picked up by the drill bit and spun like a propellor, slicing someone's fingers. A telescopic switch rod parallel with the drill bit can reduce the severity of such injury.
No telescopic guard can prevent someone drilling down through their own hand so what use are they ?

Far more important : is there a system to ensure anyone using any tool has been trained and assessed on every machine before they are allowed to use it ? Do you have the records ?
Training is the single most important thing you can do but the content must be right and the person delivering it and checking that what they taught has "gone in" must be competent.

The silly person HSE muppets our guys went to to receive "train the trainer" training started by feeding a spindle moulder from the wrong end and spat a 3 foot plank the length of their training school. Their contract was summarily cancelled.

Question:
That British Standard applies to Design and Technology in Educational & Similar Establishments.

Are you one of those ?
Says who ?
On what basis ?

In any school the Default training provider for staff is the Design & technology association DATA, We were not trained in use of guards like that described, What we were trained was that proper workholding techniques must be used to stop the work piece becoming a spinning bacon slicer!
Use of hand vices, clamps & workholding fixtures many of which you could not use properly is surrounded by a ludicrous telescopic guard. Every member of staff in the department had to do the Data training & signed to say they had done each bit. Refresher training every 5 years.

Some very good points there.
I'm still curious though. Do we think @OldGitEd works or is volunteering in a school or college ?
