Wax Wrote::0 Naughty Dinosaur!!!! the chemicals in marker pens, glue on stcickers etc can break down the plastic in those hard hats weakening them. I got my knuckles seriously rapped for writting on a helmet. Oil is a no no as well.
Of course someone might have been pulling my leg but I suspect not.
I've always assumed this was a bit of an urban myth, perhaps propagated by H&S suppliers. If stickers are so bad for them, why do they put them on to show you have taken the site induction course? If stickers are so dangerous why do they given them away in magazines for kids. Sounds ridiculous.
I'm never sure about the notion that you should only keep hard hats for a certain amount time and replace them after even a small knock. I don't honestly know if any of this stuff is genuine or just old wives' tales.
