Outside the plant premises
①By taking account of conditions around the pertinent plant, a route in which locations (such as wastewater
channels) where environmental risks come to light can be patrolled shall be established in one of the areas which
are entered in an environmental risk map and which is located around the plant. In addition, the patrol route shall
be set within accessible areas.
②The following items shall be clarified: places where failures, abnormalities, and managerial deficiencies in relevant
processes, equipment, and facilities that have significant environmental aspects in environmental risk ranges can
be surely judged; and judgment criteria. These places and judgment criteria shall be reflected in the patrol route.
Note) Pay special attention to safety when setting patrol route for night-time patrol or for patrolling dangerous areas such as rivers, cliffs, etc.
