Was wondering if anyone has experience / advice they would be willing to share? I am looking at PPE for colleagues who currently handle aluminium tube with raw cut edges / burrs etc which has to be drilled using a pillar drill. The standing instruction is that the drill is turned off between drilling while the tube is moved about ready for the next hole to be drilled. I am looking to identify PPE (potentially a glove) which would be suitable in terms of cut protection for the raw sawn edges of the tube, but which would also tear if accidentally drawn into the drill. Does anyone know of something suitable or am I asking for the impossible? Any assistance is much appreciated. CRN

A thin surgical type latex or nitrile glove could help but would probably rip constantly just from the burrs themselves. If ppe is definately required try using a glove that fits as close as possible to minimise the risk of it being caught and dragged in. Is the guarding sufficient for the operation? Surely there shouldnt be any chance of it being drawn into the drill if the procedure is to handle the tube only when the drill has stopped?

'Is the guarding sufficient for the operation? Surely there shouldnt be any chance of it being drawn into the drill if the procedure is to handle the tube only when the drill has stopped?' I suspect there is a temptation in order to 'get the job done' for guys to keep the drill on when moving the tube - hence the PPE question.

Interlock the guard? Microswitch?

Does the volume of work perhaps justify expenditure in a suitable jig or fixture to speed up this "moving about" of the workpiece, whilst also allowing a safer handling process? PPE is the last resort after all.

Andy, you have struck at the heart of the matter... under normal circumstances, the glove is suitable and sufficient, as is the guarding. It's one of those jobs where humans interfere and in this instance the process has not been correctly followed. I am looking into whether there is a more appropriate glove on the market which will protect the operative if for some reason the process is not followed. If there is something out there that means that if the operative will not be injured if something goes wrong. I'm looking for is something that is cut protection 3 but am not sure if there is a glove which will cover both sides of the dilemma, hence my question.

How about de-burring the pipe ?, I know its another operation but would save on PPE and I dare say that others also need to handle the work piece further down the line as well. I did an engineering apprenticeship many moons ago and we were always taught it was good practice to de-burr, but times change and saving a few seconds is king.

A chain glove may help, leather or cloth glovesv will be at risk of being entangled with the drill. Normal gloves are not adequate, having seen the results of an operator who used gloves after lifting the guard to operate the drill. Its not pretty.

Is this a bench mounted pillar drill? have you considered installing a drill guard to prevent fingers/hands becoming in contact... be it gloved or not?

Thank you for your assistance thus far. RayRapp, there is absolutely NO temptation to condone what is essentially unsafe working! Sadly an individual has decided to put his hand near a drill while it was in operation. This is contrary to the safe working practice currently in place. The incident is now a clearly foreseeable cause of injury through human error (failure to follow the SWP). What I am trying to establish is, is there a glove or similar which will protect against sharp edges, but which will have the flexibility to tear in contact with a drill. The drill is guarded, the SWP states drill MUST be turned off while the material is being moved into position - short of getting robots to do the job I am running short of ideas on how to minimise the risk of injury due to human error. The work piece is nearly 7 metres long hence the requirement to stop and start the drill between holes. Maybe I am approaching this from the wrong angle??!! Your thoughts are welcome CRN

I would be looking at the drill before anything. Would it be possible to engineer the drill to only operate when the bit is being lowered to the drill site and then stops when it is in the resting position? A bit like a chop saw if you can picture what I mean?

Hi CRN If the drill was guarded then forgive my naivety, but how did the operative come into contact with the moving drill bit or chuck? As surely a correctly positioned and operating telescopic chuck guard would have stopped this happening? If it was the swarf that grabbed hold of his gloved hand, then that is a different matter: drilling in stages (i.e. applying and relieving pressure on the drill handle and therefore drill bit) makes it possible to avoid really long swarf; which of course can be problematic on pillar drills. As for your enquiry about gloves then I know of no gloves that would offer suitable cut resistance yet easily tear off of hand if they became entangled in rotating machinery. I would not like to stake my pinkies on anyone’s claim of a glove of that type either. Think you have to look at training/competence of the operatives along side ensuring that any SSOW are followed, eliminating the risk of human error in this instance totally would undoubtedly require some form of enclosing/automation of this process.

The work piece is 7 metres long? Are the raw edges at the ends? Is this a two person job? If so is it not possible to arrange for one person with reinforced glove to hold the piece away from the drill while the drill operator just operates the drill one handed? (Other hand behind back). Just guessing.
