Risk Assessment
We conduct risk assessments to identify the barriers necessary to reduce the risk of a catastrophic event to a tolerable level.
We recognize three types of barrier elements that work together to make up our barrier system. 
Each barrier element must be implemented and maintained to effectively manage process safety risks:

1- Operational Assurance Program (operational assurance processes are in place to verify that our barrier elements remain healthy)

2- Self- Verification (a process of ongoing verification tasks performed onsite by site-based personnel with barrier health accountabilities.This process includes assessing the health of safety-critical assets and verification of Life Saver topics through dedicated processes and checks).

3- Oversight (supervisory verifications performed by both site-based and office-based leadership; includes Critical Area Verifications conducted by heads of departments and other line-level supervisors on the site. Also includes verification of compliance with Life Savers).

4- Audits (consist of site management and office audits of specified operations. Includes the corporate “Audit Team” who conduct sitewide audits against Operational Assurance Program protocols to drive continual improvement).
