  3. Safety in the Lab • If you are goofing off and cause an accident – you are in big trouble • You will have to pay for anything that is damaged – which could be very expensive • For example, goofing off and causing an acid spill that damages the table, carpet and floor. It would all need to be replaced. • You will also face disciplinary action • You may also suffer from the guilt of knowing that you hurt a fellow student
