Spills, drains and pollution prevention on site

Field work often involves oils, coolants, cleaning chemicals and washwater, and a few litres in the wrong drain can reach a stream. This course covers how site drains work, how to respond to a spill, who to call, and how to prevent pollution while you work, using GOV.UK (Defra and Environment Agency) guidance for England and the US EPA's National Response Center as examples. The site's own plan, local law and your employer's procedures govern; scenarios and sites are fictional.
