CONFUSING SAFETY ICONSThese icons appear in a manual that is for use by train cleaners on a rail network in the UK.
The intention is good, but the execution is not very good. For a start, the document doesn't contain a 'key' explaining what the different symbols mean. Now, I've worked with the rail sector for many, many years and I'm still not sure I know what some of these mean. The first symbol must mean 'wheel scotches to be applied', but what about the second and third? The things represented by the icons are clear enough (air pressure and battery power), but do we want the presence or absence of these? Second, what does a cross in the box below the symbol mean? Does it mean that the thing represented by the icon should be there, or must definitely not be there? The penultimate symbol shows the train pantograph lowered - but does the cross mean that it shouldn't be? |
