As a security office within a high risk environment you may work at a nuclear plant, oil & gas plant or a chemical plant.
You may participate in the emergency preparedness team as a fire-fighter or a paramedic. By performing access control and monitoring the plant by CCTV, you make sure that no unwanted incident occur or escalates. Furthermore you check if people follow the safety regulations and wear the right safety gear. Securing the production processes is of outmost importance in these environments.
