[TheThinkTank] Liability waiver

Heys,

Last week, someone that visited our shop during Open Shop got into an accident because their wheel came loose. Turns out they were working on said wheel during our shop time.

They are okay now but were seriously injured from the accident. We started talking about training volunteers better to do 'checks' before peopel leave the shop. We are also considering having liability waivers. Does anyone have an example of a waiver that we could build off of? Does it need to be very details or can it just be..."By signing below I accept the responsibility..."etc etc.

Thanks.
