  1. Safety in the World of Chemistry and Chemical Reactions Before we can work in the laboratory and perform some chemical reactions, we need to learn/review a little bit about safety with chemicals.

  2. Safety • Chemicals can be hazardous to human health if they are not used safely. • Many household products are labelled with Hazardous Household Product Symbols. • What are some examples of items in your home that have these symbols on them?

  3. Hazardous Household Product Symbols (HHPS)

  4. Safety in the Workplace: WHMIS • The Workplace Hazardous Materials Information System (WHMIS for short) is a comprehensive national system for safe management of hazardous chemicals which is legislated by both the federal and provincial jurisdictions. • In summary, WHMIS delivers the necessary information by means of: • cautionary labels on containers of controlled products • the provision of an MSDS for each controlled product • a worker education program The ultimate goal is to create a safer workplace by providing workers with the knowledge and tools to enable them to work safely.

  7. What is an MSDS? • MSDS – Materials Safety Data Sheet • Every chemical that arrives in the workplace (or the school, for example) is accompanied by an MSDS, which outlines: • Hazards associated with the chemical • Protective clothing that should be worn when handling the chemical • Steps that should be taken if the chemical is spilled http://www.sanisys.com/image/MSDS2.jpg
