Fast 41

Common in tank inspections, flare stack maintenance, and structural repairs. Subcontractors must ensure crews hold valid IRATA or SPRAT certifications before mobilising.

Subcontractors are typically required to participate and document compliance as a condition of their contract. It often involves toolbox talks, harness inspections, and audits by the prime contractor.
Winterization
ComplianceThe process of preparing equipment, vehicles, and job sites to operate safely in cold weather conditions. For subcontractors, this includes insulating lines, servicing cold-weather gear, and updating cold-weather operating procedures.
