BoS Drawing Challenge - #97 Safety First

Another theme that had me stumped for a little :

Then I thought of safety hats ( as you do ), and then I couldn't get the idea of 'Hard Hat Mack', a video game from the early 80's, out of my mind. I used to play it on the Apple computers at school, and I eventually got it for my own Commodore 64. A fun little game - though it didn't have a great deal of levels.
