Posted By Phil Grace Jom, I'm no expert - and most of my accident photos were taken with a Polaroid - so you can tell how long ago it was!. Nowadays I just photgraph work activity for training presentation. I find that relatively easy a with digital camera. I would say that lighting may not be something you Can control. I'd advise taking sufficient "general shots" to make sure someone not familiar with the location, plant, equipment etc can put everything in context. People make good markers to indicate scale. Then gradually take shots that "lead in" to the exact location of accident. Remember that these will be no use with the previous ones - because whilst you'll be able to position/orientate everything others outside your business/firm industry etc may not be able to. Remember as you gradually take shots closer to the point of accident it will be important to include a "scaling device" - ruler is best but anything that indicates scale is just as useful e.g. pen, soft drink can, coin etc. Finally make sure images are dated and that each has a description. Hope this is of some use.

Posted By Phil Grace Jom, I usually have to rely on what can be viewed on the camera screen - not the best plan I know. I would guess that downloading onto a laptop and viewing on the big screen might be a luxury!! I'd suggest taking a selection - with flash on/off in a hope that something works out "OK". I would resist the temptation to alter pictures using a photo processing package although I do correct exposure issues when using pics for a presentation. One way round that could be to adjust exposure or contrast but to make this clear by placing altered image alongside the original. That way it can be confirmed that nothing has been added/taken away. The "airbrushing effect" is perhaps the one drawback with digital images - and for accident investigation pictures perhaps you need to get others to verify images immediately after they have been taken e.g. a statement or similar. Hope this helps. Phil

Posted By JEB One thing to need to do is have a size reference in a photograph, e.g. tape measure in the photo alongside a hole in the floor.

Posted By Kieran J Duignan IN answer to your question, I recommend: Investigative Photography, written by John Wenzel and published last month year by ASSE. You can order it online from www.asse.org

Posted By Kieran J Duignan Yes, John though you could buy a couple of copies of the book for the price of the webinar! (I took the advantage of paying for the transatlantic postage to order a title on behaviour safety which is much more expensive, even secondhand, on Amazon). What I liked about Wenzel's text is his chapter on sketching before you photography - it makes you think through the angles you want to include in any shots. As I specialise in musculoskeletal disorders, this is nececessary for anyone who's not comfortable with at least A level mathematics (for the calculus involved in the biomechanics of ergonomic interventions about MSD risk control). If you or others want to exchange ideas on safety photography, you're welcome to do so through kieran@simplyenabling.com

Posted By Kieran J Duignan John As an ergonomist dedicated to user-centred design of work and workplaces, I use the expression 'safety photography' to refer to recording interfaces which present controlled or uncontrolled hazards at work. Part of my interest as an ergonomist is to encourage Safety Professionals as well as HR, Facilities and Quality Management specialists to recognise how designing 'work and workplaces' offer scope for joint and mutual benefit through collaboration; and that ergonomics and photography can offer useful contributions to how they create value.
