View reactions horizontally, keeping glass and safety glasses between you and the reactants. Do not look into the open mouth of a test tube or reaction flask. Point the open end of the tube away from you and other laboratory workers. Be a good housekeeper. Order and neatness will minimize accidents.
Laboratory safety is the personal responsibility of each and every individual in a laboratory.
Report unsafe practices. Treat all chemicals as corrosive and toxic and all chemical reactions as hazardous unless you know them to be otherwise. Once you have withdrawn chemicals from the stock-bottles, never place them back into the bottles. A potential mistake or moisture in your equipment may cause malfunctioning of the chemicals used by the whole class. Instead, discard these into organized waste in the hood.
