The Contractor Health, Environment and Safety Management Process establishes clear accountabilities, ensures active engagement of contractors, and provides a consistent CHESM program to eliminate health, safety and environment (HSE) incidents and injuries involving contractors.
The requirements and activities included in CHESM process are focused on defining TCO expectations regarding contractor HSE performance, the qualification of contractors and the monitoring of contractor performance against expectations.
Contractors involved in activities presenting risks to workforce and process safety are subject to CHESM Qualification to evaluate HSE Management Systems and ensure adequate safeguards are in place and functioning before starting work at TCO Facilities.
TCO's work is guided by two key principles: do it safely or not at all and there is always time to do it right. Every employee of TCO and its Business Partner companies is responsible for making sure that work can be safely started. Each person has the right to temporarily suspend or completely stop any work if unsafe behavior or conditions are observed. The TCO Safe Work Practices Management Group, together with other teams, ensure that Occupational Safety and Health (OSH) guidelines and procedures are continuously implemented and maintained.
