Hazardous Substances and the Environment
Always make sure that while working at the host site, you store, handle and use hazardous materials correctly to prevent leaks and spills that could harm the environment (or people). Incorrect handling of substances can pose a risk to the environment as well as health and safety.
Take care to see that hazardous substances and effluents, associated with the work activities, are not disposed of down drains. You can always check with your host what arrangements are in place.
