Laboratory Safety Using the GHS pictogram (encircled) below, give an example of a reagent that you studied that used one or more of these hazard labels. GHS - Hazard Pictograms and Related Hazard Classes 1 Exploding Bomb - Explosives - Self-reactives - Organic Peroxides Corrosion - Skin corrosion/burns - Eye damage - Corrosive to metals 2 Flame Over Circle - Oxidizing gases - Oxidizing liquids - Oxidizing solids 3 Gas Cylinder - Gases under pressure Enviroment - Aquatic toxicity Skull & Crossbones - Acute toxicity (fatal or toxic) 4 5 6 Exclamation Mark - Irritant (eye & skin) - Skin sensitizer - Acute toxicity - Narcotic effects - Respiratory tract irritant - Hazardous to ozone layer (non-mandatory) Health Hazard - Carcinogen - Mutagenicity - Reproductive toxicity - Respiratory sensitizer - Target organ toxicity - Aspiration toxicity Flame - Flammables - Pyrophorics - Self-heating - Emits flammable gas - Self-reactives - Organic peroxides

Exercise 1: Mapping Laboratory Safety Use the following page to draw a map identifying your safety elements and where you will complete your lab experiments. If you do not possess a safety item, indicate the location of the closest one that you can use. Use the list below to identify items on your map: a. Clean, dry, uncluttered laboratory workspace b. Window for ventilation c. Trash can d. Sink (eye wash station) e. First aid kit f. Fire extinguisher a. Phone b. Storage location for your eScience Lab materials when not in use c. Computer d. Blanket that can be used to smother a fire (fire blanket) e. Shower that can be used to wash off spilled chemicals (safety shower) f. Exit door (Diagram on your map the route you will use to leave the building in case of an emergency.) g. Smoke detector
