It is common to establish trigger levels as part of regulatory requirements. A trigger level is a specific value set for a particular parameter, such as the concentration of a particular chemical. When this trigger level is achieved or exceeded, the licence holder is required to take certain actions to mitigate the risk or address the issue. For example, if a chemical company’s trigger level for a particular chemical concentration is exceeded, they may be required to shut down operations until the issue is resolved or take other corrective measures to prevent harm to the environment or public health. Trigger levels are an important tool for ensuring compliance with regulations and promoting safety and responsibility in various industries.
