BWXT NEC is able to identify and trend fire incidents and determine corrective actions taken. Where deficiencies are identified, action plans are developed and implemented to prevent the occurrence of similar incidents. All fire incidents are investigated by a qualified person and fire experts are solicited when required. Appropriate authorities are notified for a fire or uncontrolled combustion event that causes injury or property damage and has the potential to result in severe consequences.

Program Review A fire protection program audit is conducted every three years on each program element to confirm compliance with CSA N393 and other applicable codes, standards and industry best practices in fire protection. Quality Assurance programs apply to verify that the fire protection systems are designed, fabricated, implemented, tested, maintained and operated as intended.
