Appendix A - General laboratory safety rules1. IntroductionThe original intention was to limit the scope of Appendix A to the use ofsolvents only. However, it was later decided that all aspects of safety in alaboratory should be included as a limited edition might leave the rulesopen to misinterpretation and expose the authors to liability.Many of the guidelines/rules set out in this Appendix are furthercircumscribed in statutory requirements.The first step in establishing laboratory safety rules is to conduct a riskassessment. Thereafter the rules are established based on the risksidentified from the hazards present in the laboratory. The risk assessmentshould cover the following areas:• Hazard communication;• Chemical storage;• Personal Protective Equipment (PPE);• Handling and use of chemicals;• Fire and gas safety;• Hazardous waste management;• Ventilation and fume hoods;• Physical hazards, ergonomics, safe conduct and housekeeping;• Equipment safety;• Emergency procedures.2. Hazard communicationIt is important that all laboratory workers and visitors have access to andare exposed to all information on hazardous materials. This information isprovided by means of product labels, MSDS as discussed in Appendix C,warning signs as well as training by appropriate professionals so thatworkers are able to interpret hazard warning information. HSE/HSEQ policydocuments must contain an approved list of acceptable laboratoryabbreviations. This permits laboratories to use abbreviations on labels etc.However, a list of abbreviations must be posted in the laboratory, preferably34
in a location close to where the products are stored; and a list must beincluded with the MSDS file. Hazard communication occurs via:• Labelling - Labels identify as well as alert people to the dangers ofthe product and basic safety precautions when handling the product.A label may be a mark, sign, stamp, device, sticker, ticket, tag, orwrapper and must be attached to, imprinted, stencilled or embossedon the container of the controlled product.There are two types of labels: supplier labels and workplacelabels. Supplier labels: Suppliers are responsible for making sure theirproducts are clearly labelled. A supplier label generally containsthe following information:¨Product identifier (name of product);¨Supplier identifier (name of company that sold it);¨Impurities, other components;¨Flash point (where applicable);¨ Storage colour code;¨ Hazard warning/rating/class;¨ Risk descriptor (danger, warning, caution, etc);¨ Risk descriptive statement;¨ Handling advice (how to work with the product safely);¨ First aid measures (what to do in an emergency);¨ Reference to the MSDS.Supplier labels may also contain additional information suchas:¨¨¨Identification numbers (i.e. CAS number, UN number andbarcodes);Recommended PPE;Recommended fire extinguisher class.These supplier labels must be provided in the officiallanguage of the users.35
