    Default Lathe Safety Guidelines.

    Unfortunately we tragically lost a woodturner here in Australia just before Christmas. These tragic incidents do happen but they seem to be happening more frequently so I have updated work I commenced to improve hazard & risk management when I was Secretary of the local woodturning club.

    Safety, identifying & controling hazards and reducing risks should always be at the forefront of what we do in woodturning.

    Lynne Yamaguchi's blog should be required reading for all turners - My Turn

    Here is the full text version.

    Lathe/Workshop Safety Guidelines

    Wood turner’s use a wide range of tools, materials and processes in their project activities, many of those substances and processes may involve risks and hazards which if uncontrolled may present short or long term adverse health risks, injury or death. You must read, understand and follow safety guidelines, safe work practices, and warnings in operator’s manuals for the items and products you use.

    Preparations for commencing a project

    1. Research and Plan the processes and construction sequences for your proposed project. It is highly recommended that you seek training or advice and supervision from experienced turners if new to turning or you are taking on advanced projects.
    2. Hazard Identification - implement a process of hazard identification and risk minimisation paying particular attention to electrical and machinery safety procedures or tasks involving hazardous or flammable goods. Any identified task which presents a risk of severe, critical, life threatening injury or death no matter how unlikely must be managed by implementing hazard reduction procedures immediately!
    3. Manuals. Consult machinery, tooling, lathe and chuck manufacturer’s maximum speed or capacity recommendations, they exist for your safety, so DO NOT EXCEED them.
    4. Reduce Hazards. Understand the likely hazards to be encountered, volatility and flammability of materials; potential ignition sources; cut, crush, pinch, nip, kickback hazards; the speed, mass and impact level of particles and objects, and other physical hazards intentionally or unintentionally created in the processes used. Potential hazards include distractions from outside sources including animals and visitors.
    5. Material Safety Data Sheets, Consult MSDS’s and technical bulletins for the materials you use. Follow recommended practices for handling, storage and use. Materials may be flammable or dangerous goods, or are known to have short or long term adverse health reactions, some of which may be very fast acting, severe or life threatening.
    6. Personal Protective Equipment. Acquire and use recommended PPE to meet the required protection standards for hearing, lung, face and eye protection and hazard exposure level for the proposed tasks and materials used.


    • Face / eye protection – recommended approved safety goggles or safety glasses with side protectors at minimum PLUS a full face shield for low impact protection; or a high impact face shield for higher impact protection.
    • Lung protection – mask, respirator or forced ventilation helmet to suit hazard level from toxic / spalted woods, wood dust, fungi, solvents, sealers, and finishes used.
    • Hearing protection – ear plugs, and/or ear muffs appropriate for the noise level & duration of exposure experienced.
    • Foot protection – wear sturdy and preferably steel toe capped safety boots.


    7. Prepare. Assemble the tools and materials required to complete a task and the personal protective equipment required before commencing any activity on the lathe. Develop an emergency contact plan and have a means of getting assistance if things go wrong.
    8. Avoid Entanglement, ensure clothing etc. is not loose or presents a risk of entanglement in rotating / moving parts – wear sturdy close fitting clothes, tape sleeves and cuffs if necessary. Remove jewellery and dangling objects, tie back long hair, and preferably use a hair net, not a cap.
    9. Ability. Be aware of your level of competence and the capacity of your lathe, machinery and tooling – do not over extend your abilities, tooling, machinery or lathes capacity without supervision and informed advice.
    10. Fatigue. Do not operate workshop equipment whilst tired, under the influence of alcohol, prescription or other drugs. Be aware that common prescription drugs may cause drowsiness or alter your perception. Some medical conditions or disabilities may require additional hazard and risk management for implanted medical devices, partial blindness, hearing impairments etc.
    11. Maintain personal protective equipment, machinery, lathes & tools in good condition. Keep tools sharp and clean for improved and much safer performance. Do not attempt to force a dull tool or use a tool for a purpose it was not designed or intended for.
    12. Familiarise yourself with the machinery and lathe controls, positioning of switches, mains power isolation, fire extinguishers, check that all safety features and machinery guards are in place and functional and ensure that you maintain safe access to them.

    Commencing a turning project

    13. Examine turning blanks or spindle stock for splits, cracks, foreign bodies, knots, checks, bark pockets, irregularity of shape, balance, protuberances etc. Trim & stabilise before commencing lathe activities or machining. Ask yourself is it worth the risk?
    14. Isolate the lathes power supply, before mounting a turning blank or adjusting belt positions on the lathe or before effecting repairs to the lathe. Avoid accidental start ups.
    15. Holding Techniques. Follow recommended safe practices and instructions for the proposed method of holding, either wood screw, face plate, mechanical chuck, and glue or jam chucks etc. Understand the load bearing capacity of the work holding techniques, glues, screws & bolts used with them. For turning between centres ensure the work piece is firmly mounted between the headstock drive centre and tailstock live centre. Get assistance or use lifting aids for heavy blanks.
    16. Recommended Turning Speed is determined by diameter and dynamic balance of turning blank, slow speed for larger diameter bowls / platters and or unbalanced work; higher speeds for small diameter spindle work, smaller diameter bowls and pieces that are balanced. Consult and DO NOT EXCEED lathe and chuck manufacturer’s maximum speed or capacity recommendations. A guide to safe turning speeds is Bowl or spindle blank diameter (in inches) x lathe RPM = 6000 to 9000; however this must be adjusted down for unsound blanks. Use and maintain tailstock support for as long as is practical.
    17. Lathe Direction. If your lathe has a reverse feature, ensure that you use a securing grub or set screws on face plates and chucks when running in reverse or use manufacturer’s approved accessories and follow their recommendations.
    18. Adjust the tool rest height and banjo position to suit the blank and turning tools.
    19. Select Appropriate Turning Tools for the task at hand. Be aware that some tools, shapes or grinds offer considerable advantages over others and that some tools are known to be very hazardous in particular inappropriate uses, e.g. do not use spindle roughing gouges to true up face grain bowl blanks.
    20. Habit. Form checking habits / routines before turning on the lathe – always check PPE; spindle locks are disengaged; remove chuck keys, adjusting tools and knockout bars; check firmness of all clamps; hand rotate the turning blank at least one full turn before starting the lathe. Check the dynamic balance and consider the use of dynamic balance systems to reduce vibration of large blanks.

    Starting the lathe

    21. Verify the lathes power supply is reconnected and that the lathe is in the “Off” position and variable speed control is adjusted to zero or belts are positioned at the recommended setting for the proposed task. Ensure “forward” is selected if the lathe has a reversing feature. Ensure your PPE is adjusted correctly and is being worn!
    22. Stand Aside - outside the “red zone” or “firing zone”, an area considered the most hazardous and most likely area for a work piece or part of it to fly off when starting or performing tasks on the lathe. It is an area directly behind and in front of the spinning work piece or perpendicular to the lathe bed or turning axis for adjustable headstock lathes.
    23. Perform a last check & Power Up the lathe keeping a hand over the off switch in case an emergency shut down is required. Immediately shut down if excessive vibration occurs.
    24. Observe the dynamic balance of the blank and speed and adjust speed as required with variable speed control if fitted to minimise vibration. Observe recommended speeds!
    25. Stop & Check the lathe, check the work piece is still mounted securely and that all clamps are still secure etc. When satisfied restart the lathe. Remember the PPE!

    Commencing tasks on the lathe

    27. Position yourself comfortably in front of the lathe, maintain proper footing and balance at all times and particularly before commencing a cut. Have a dry run with the lathe off if necessary to check range of body and tool movement required etc. NEVER over reach, or attempt to reach across a running lathe to access tools or other materials, stop it first. Minimise positioning your body in the “Red Zone” where ever possible. Place tools in easily accessible locations and avoid placing tools or other items behind the lathe, on headstocks, or lathe beds without appropriate accessories to prevent them falling.
    28. Place turning tool firmly on the tool rest, holding the tool in a neutral cutting position before commencing a controlled cut. The tool must always contact the tool rest before contacting the rotating blank. Tool grip should be sufficiently firm and comfortable. If the tool requires very firm pressure or force to create a cut or to control, stop and check tool sharpness, direction of rotation etc. Use trim cuts to balance the blank first then commence shaping cuts.
    29. Routine, shut down the lathe before adjusting tool rest height & position. Always remove the tool rest before sanding, finishing or polishing operations. Check PPE!
    30. Stay Alert, look and listen to what is occurring. Often a noise or sound will alert a turner to a sudden or gradual change to the stability of the turning blank. Stop & investigate strange noises or occurrences immediately.
    31. Learn safe methods to reverse mount work pieces to finish off the bottom or to complete multiple chucking / mounting operations if required.
    32. Safety - implement safe practices. Do not use large pieces of cloth to apply finishes to rotating work pieces, use paper towels as a safer option. NEVER wrap cloths, sandpaper or burnishing wires, around fingers or hands. Do not insert fingers into small openings in rotating work pieces.

    Finishing for the day or temporary breaks.

    33. Isolate & Make Safe. NEVER leave a lathe (or any machinery) running unattended. Turn power off and ensure the lathe (or machine) is isolated and comes to a complete stop before leaving it. Consider installing no volt protection switches (in case of power failure or improper shut down) and lock out devices if necessary to isolate or prevent unauthorised use.
    34. Housekeeping, Pay attention to good housekeeping practices. Remove waste regularly, use correct disposal methods especially for cloths, paper towels and steel wools used to apply oil and other finishes. Delayed spontaneous combustion may occur in favourable environmental conditions. Return tools to their place & arrange any necessary repairs.


    Please do not become complacent about your safety!

    Be safe, have fun, explore and enjoy wood turning. If you are supervising a learner or another turner, be aware that you are responsible for the safety of both parties, offer praise and advice in a non threatening manner, and be firm when unsafe practices are employed.

    Refer to manuals, safety procedures, technical bulletins and Material Safety Data Sheets often and particularly when using new tools, machinery or products. Take the time to constantly review hazard reduction procedures and adopt risk minimisation strategies in your workshop. Check your environment, mechanical and electrical safety, lighting, ventilation, dust control etc, and the hazards and risks of the task/s you are about to undertake.

    Be aware that in your area, machinery, electrical, health and safety legislation may exist to control, restrict or prohibit some activities or procedures. You may be legally liable for injuries or damage caused to others or face potential prosecution for breaches under existing legislation.

    It is an unfortunate fact of life that some incidents will always occur despite all the best intentions, or adopting safe procedures and education programs, because humans are adventurous and curious, they are also fallible and make mistakes for various reasons, or become complacent.

    By adopting safe routines we can at least control most hazards and minimise risk.

    Thanks for the link on the safety guidelines - I reckon 's videos are maybe more likely to be taken notice of than yet another piece of paper.

    Just a comment about Lynne's calculations on her blog.
    Lynne makes the assumption that all components of a rotating object will have the kinetic energy as determined by the linear speed of the outer radius of the object whereas the more complex rotational dynamics of the whole object and the piece that breaks off has to be considered.

    At 1200 rpm a 250 mm diam by 125 mm long piece of wood with a density of 1 g/cc will have a mass of 6.1 kg and a rotational KE of ~380 J.
    if a 1 kg lump splits off all the way into the centre line of rotation (which is what appears to have happened to Lynne) then 1/6 of the KE (~63 J) will be involved which is <1/2 what Lynne calculates. Lynne does say her calculations are simplified but it does mean the riot helmet she discusses will easily meet the spec needs of her accident. The key factor behind the way these helmets and shields work is the 3 D curved surface spreads the impact over much more than a 2D or 1D face shield structure.

    I have had a 45 J impact into my el-cheapo (2D) face shield while using a chain saw and it was like being hit by a cricket ball ie it fair whacked the face shield into my face - fortunately all I got a small bruise around the bridge of my nose. Have since upgraded to a curved face shield. I use the same type of shield on the lathe. One brand to go for is the Armadillo brand - I think is a fan of these.

    Great response. True its another piece of paper but if we put it all in one place in a logical manner maybe, just maybe, some one will read it & take something from it which prevents them becoming another statistic.

    Lynne admits she simplified the calcs but it is still a good message to all.

    I personally dont agree with Riot Helmets, they do spread the impact load but to where? The neck etc! Perhaps better to have a neck injury than be dead I suppose. Better not to get hit in the first place by such forces. I also like the Armadillo & its what I wear for the impacts I expect may occur.

    I didn't read it in detail, mainly because it isn't easily readable and as such most people will not read it either.

    To improve it I would suggest a lot more spacing between points and paragraphs, much easier to see where you are up to. (coincidentally a common failing of many posters here as well).

    Also it comes over as hard bureaucratic haranguing, like do this and do that.Removing the fog and unnecessary words and making it more personal would IMO greatly improve it.

    For instance
    Consult machinery, tooling, lathe and chuck manufacturer’s maximum speed or capacity
    recommendations, they exist for a reason, so please DO NOT EXCEED them.
    could be better put as

    Please do not exceed the maximum speed or capacity of your lathe or chuck, if not sure check this with the manufacturer.
    Hope this helps.

    I've argued with the other instructors at work about using the term "please" in instructions, especially safety instructions. My take is that safety instructions are not suggestions but expert information, I don't think we should pleading with student to take them on board but just be up front and tell them, this is how it is. Where there is some degree of vagueness or interpretation involved I tend to use something like "recommended" or "strongly recommended".

    That may be appropriate in a place of learning where students are required to follow instructions BUT here we are not dealing with such students.

    Here we are trying to reach adults who may well ignore good advice if they don't like the way it's presented. That's why 's videos are so good as they are down to earth and don't harangue us.

    The instructions for workplace and equipment use I have written apply to everyone from full professors, technical staff, post and undergraduates through to visiting high school students.
    Sure it's more of a workplace environment than a weekend warrior's backyard shed so there would be some differences in the way it is written.
    Despite this, I reckon asking someone to "please do not stick your fingers under the moving blade" implies a dangerous choice or option, certainly for a mens shed it would not pass an OSH guideline for an instruction.
    Take a look at how instruction manuals provided by tool suppliers are written - you won't see too many "pleases" in the text - it's do or don't.

    TL,
    Ken Wraight posted on another forum the passing of a Griffith woodturner just before Christmas.

    There have been at least 4 deaths world wide in wood turning in the past couple of years and some pretty nasty incidents as well which could have easily been fatalities. There appears to be some commonality in that they involve severe head injuries, just not enough reliable info to know for sure. I know of two incidents of concern similar to Lynne's and another near fatality involved over 100 stiches to the neck from using a Lancelot carver on an angle grinder contrary to safety instructions & warnings. I'm sure there are many more near fatalities and severe hand injuries etc we don't hear about. Woodturning is a small community so any death is a tragic loss to us all.

    Currently on this forum there is a post about a 5kg blank going awol!

    All,
    The "please do.." makes it all sound discretionary, which it isn't, I will fix that in the next update!!!

    Either you get serious and adopt some sensible safety routines to protect yourself and others nearby or you take your chances. Entirely up to the individual in home workshops, but in a club situation you had better show you are doing something with the new the national model WHS Regulation.

    Any way take it or leave it - the guidelines are my attempt to bring it all together. Others are welcome to use all or part of it & to put their take on it and use it in their clubs under the terms of the Creative Commons licence.

    I'm also very receptive to meaningfull constructive suggestions for updates.

    I agree spacing would help make it more readable & would be handy but that makes it 6 pages! You can always format it as you wish, all you have to do is ask for the original & I will supply it OR you are welcome to copy and paste from the PDF file. (In Adobe Reader use "select all" > Copy then Paste into Word and format away to your hearts content.)

    You can have the best written instructions, with all the specific details including all the safeguards as required by OSH. No doubt covering many pages, similar to the manuals we get with each machine, that nobody reads.

    Or


    You can write it in a simplified way, using normal and polite language, not haranguing and it may be read by the target audience.


    Let Mobiturns take his pick, but I know which one may be read and which will be ignored.

    Peter,
    I value your input and will welcome suggestions you wish to contribute to make it more readable. I have adopted your suggestion re spacing and attached the new PDF.

    Unfortunately we have suffered many poorly written "manuals" (and I use the term loosely) supplied with machines. If people think they know it all, no manual will help them, no matter how well written it is! We can only lead a horse to water.

    Sadly wood working / turning clubs are being forced to comply with new national H&S laws which will make them put more responsibility on members to comply with safe work practices. In my opinion we should selfishly be doing that anyway irrespective of laws for our own safety!

    Regards
    Geoff

    Moby, the hard part is trying to change the older tradesmen, whom have being doing this since Adam was a boy. They still use practices, that they learnt young. It's a case of look away or "Hey Pete, I'll tail out for you . . . Where are your push sticks?" They know the requirements, but it's normally a case of " I've done this job a thousand times . . . " They also generally have a shortened digit somewhere.

    Pat we can only try - they have to realise that now its no longer discretionary its now a case of must under the new national H&S laws.

    A very experienced cabinet making friend of my family was a few days from retirement and trimming up some pieces on a panel saw. He finished and switched the saw off and went to flick the off cuts off the table saw when he took two digits off a hand plus made a mess of the rest of it. Spent the first week in retirement undergoing surgery and it was 6 months before he could use it in even a limited way.

    The trouble with that attitude is they forget time marches on, it's a couple of days since they last did it and around half a century since they first did it, and we are all slowing down.
    As for the supplied manual, I get annoyed with the ones that give the same list of safety rules whether it's with a lathe, a drill, a sander, a router or what ever and pages of high tec electrical data on how they comply with the radio interference under the various standards of the countries the might be sold in. Is it any wonder they don't get read?
    Regards
    Hugh
