2THE IMPORTANCE OF LABORATORY SAFETYA fundamental skill that any scientist must have is theknowledge and practice of good laboratory safety.Laboratory safety procedures exist to:•prevent injuries or even death;•prevent property damage.The safety practices presented here are required andstrictly enforced. Serious violations may result in yourremoval from the class and a score of zero for thatday’swork.
4Personal Protective Equipment (PPE)Working in a chemistry lab means working with glassware,fire and other heating elements, and dangerous chemicalslike strong acids and bases.Your first defense against injuries that could result fromthese hazards is to wear protective items such as labgoggles/glasses, a lab coat, and gloves.
5Personal Protective Equipment (PPE)Eye protection must haveclear colorless lenses.Dark,mirrored,ortintedlensesareNOTallowedbecause they inhibit yourability to record accurateobservations.YESNONO
6Personal Protective Equipment (PPE)Prescription lenses alone orwith clip-on shields are NOTpermitted, but may be wornunderneathsafetyeyewearthat fits around them.Eye protection must havebuilt-in side shields.Shields must be integral tothe frame for protection fromchemical splash or spray.Integralside shieldsYESNO
7Personal Protective Equipment (PPE)Eye protection must haveANSI safety rating Z87 (Z87+, Z87.1, Z87.1+, Z87.2).Z87 certifies the durability for lenses and frames, and theexpected degree of protection from blunt impact, non-ionizing radiation, and chemical splash. This rating will beon the frame or lenses, in addition to the package label.printed safety rating
8Personal Protective Equipment (PPE)Laboratory coats must havelong sleevesand must bemid-thigh lengthor longer.Coat features must be of a lengththatofferssufficientcoverageand,therefore,protectionfromjagged edges, heat sources, andchemical splash.
9Personal Protective Equipment (PPE)Both your eye protection and laboratory coat must beput on BEFORE entering the lab.You will not be allowed into the lab until you are ready tosafely work around laboratory materials.Additionally, your lab coat must befully buttoned.An unbuttoned lab coat is as no lab coat at all, leaving youexposed and at risk for all the hazards of a laboratoryenvironment.
10Personal Protective Equipment (PPE)Gloves are provided in each laboratory andmust beworn before handling toxic orirritating substances, andremoved before touching anything not apart of the lab.Nevertouchyourface,cellphone,waterbottle,etc. while wearing gloves;chemicalscananddotransfer between surfaces!
