If you thought health & safety was a relatively new phenomena - then take a look at this promotional "Safety in Industry' Metropolitan - Vickers electric van.
In case you can't make out the posters - from left to right they read:
"Eyes and no eyes: Wear goggles"
"Less than one-quarter of all accidents are due to machinery! The other three-quarters can only be prevented by YOUR care and co-operation."
"He was proud of his old school tie - but it will never be the same again"
The aids to safety on display beneath the posters are a safety belt (for overhead work), leather gloves (for rough work), rubber gloves (for high voltage), goggles (for fettling or grinding), respirators (for dust or flume-laden atmosphere), steel-capped boots (for foot protection) and a rather fetching leather apron (for the welder or smith).
And don't be fooled into thinking that electric delivery vans are new either. Modec and Smith Electric Vehicles might be in the news a lot at the moment - but Metropolitan - Vickers were making them decades earlier. There's plenty of information on Metropolitan - Vickers on wikipedia if you are interested.
