Corrective Action

A measurable signal that predicts future performance before problems occur. For subcontractors, examples include near-miss reports, toolbox talk attendance, and equipment inspection completion rates. Tracking these helps crews catch safety or productivity issues early.

A trench safety method where excavation walls are cut at a gradual angle to prevent collapse. Subcontractors must apply correct slope ratios based on soil type and provincial regulations. Non-compliance can halt work and trigger serious liability.

Federal regulations setting discharge limits for wastewater and pollutants released from industrial worksites. Subcontractors handling fluid waste, drilling muds, or site runoff must meet ELG thresholds or face penalties. Non-compliance can halt operations and void contracts.

Any part that contains or holds pressurised fluid, such as a valve, fitting, or vessel wall. Subcontractors handling these parts must meet strict inspection and certification requirements. Improper installation or repair can trigger liability, stop-work orders, or regulatory penalties.

Subcontractors are typically contractually responsible for completing all locates and documented checks before breaking ground. Failure to comply can void insurance coverage and expose your company to full liability for strikes.

A formal engineering assessment that determines whether aging or damaged equipment is safe to keep operating. Subcontractors may be required to conduct or document FFS evaluations before resuming work on pressure vessels, pipelines, or structural components. Results directly affect your scope of work, liability exposure, and project timelines.
