In the petrol-chemical industry, SHE programs evolved from multiple sources, such as the American Institute of Chemical Engineer's Center for Chemical Process Safety. In ExxonMobil, SHE programs are managed through the Operational Integrity Management System (OIMS), which draws upon those chemical industry best practices. OIMS is comprised of eleven key elements that define aspects of sound SHE operations. OIMS provides for definitions of what is expected as well as providing specific best practices.
Specific OIMS elements are:
Management Leadership, Commitment, and Accountability
Risk Assessment and Management
Facilities Design and Construction
Personnel and Training
Operations and Maintenance
Management of Change
Third Party Services
Incident Investigation and Analysis
Community Awareness and Emergency Preparedness
Operations Integrity Assessment and Improvement
Unfortunately, the petrol-chemical industry—unlike some industries such as commercial nuclear power where clear SHE-security relationships are mandated—has typically not addressed security matters in development of best practices. For example, Nuclear Regulatory Commission (NRC) requirement NUREG/CR-1345 is entitled Nuclear Power Plant Design for the Reduction of Vulnerability to Industrial Sabotage and requires facilities to consider sabotage scenarios in design. No such recommended practice exists in the AICHE Center for Chemical Process Safety documentation.
