It may also be appropriate to provide awareness training to contract staff working on your site. Company s often employ contract cleaning, canteen and security staff, who spend a lot of their time on your site, and could affect the environmental performance of the company. For example, do cleaning staff empty cleaning chemicals into surface water drains? Do canteen staff dispose of cooking oils down surface water drains? And do security guards know which authority to contact in the event of an environmental incident on site?
