food eaten before going out drinking to ensure you don't get too hammered too fast.
1: Dude, be careful you're drinking pretty fast.
2: No worries I had a safety sandwich earlier.

Get the safety sandwich mug.
Food eaten after a night of drinking to ensure you do not blow numbers the following morning. Prevalent with Australian Miners after a hard night at the wet mess.
1: Dude, be careful you're drinking a fair few, you don't want to blow over in the morning.
2: No worries man, I'll make myself a safety sandwich.
1: Sweet, good idea! Pass me a drink.
