Does anybody know where I can find a safety helmet (.obj) ?

I have seen images with characters wearing them, but I haven't been able to find a single one. I need the european plastic type. I've tried every name I could think of: hard hat, construction helmet, whatever, came up with nothing : (

I need it for a safety instruction demo like the picture below, DAZ seems ideal for that.

 

 

Thanks in advance,

Cheers!
