All signage needs to be obeyed and instructions followed. If the chain and sign are dropped for any reason they must be re-hung when finished and left clean and able to be read. Try to avoid laying then in mud. All mine signage is relevant to mine standards
Professionals and signage, the reason it’s there is because off you guys. I know you think that I have just insulted you. Well maybe just a little, but this is the mistake new professionals make by jumping all over miners about signs not being hung when one of the new professionals gets themselves into trouble by not reading a sign or driving straight through it about once a month depending on mine size and turn over. The best thing to do if you think the sign should be hung just hang it.
