Safety from the point of view of a safety manager who deals with admin stuff
"You must wear lab coat, it's an image of the institute."
"You must throw your used gloves into the biohazard bin. If external auditor see this in normal waste bin, it will affect our reputation."
"I hope you all can follow the rules, hopefully next year we can pass the safety review with better mark."
Safety from the point of view of a deputy CEO who does lab work
"You must follow the protocol. You are responsible for your own health and safety. Do wear gloves & lab coat when touching EtBr contaminated gels."
"You must treat your waste carefully. Think of the environment when you discharge contaminants into the drain, when you pour them down the sink. Be responsible to the environment."
"Safety is not something about pass or fail. It's not about I hope you will follow this or that. You ARE expected to comply to these regulations. Lastly, I wish you all a good research year with fruitful results."
