Protective Systems

A regulatory authorisation required before construction or field work begins in coastal or tidal zones. Subcontractors must confirm permit approval before mobilising crews or equipment to shoreline sites. Work started without this permit can trigger stop-work orders and significant project delays.

The process of shutting down and locking out all energy sources — electrical, hydraulic, pneumatic — before maintenance or service work begins. Subcontractors are typically required to follow the site owner's specific isolation procedures and permit system. Non-compliance can result in immediate removal from site and liability exposure.

Materials or conditions that can cause fires, explosions, or toxic releases through chemical reactions when exposed to heat, water, or other substances. Subcontractors must identify these hazards before work begins and follow site-specific handling protocols. Common examples in oilfield and construction work include peroxides, unstable gases, and certain drilling chemicals.

An accidental hit on a buried utility line — gas, electrical, or telecom — during excavation or drilling. Subcontractors face immediate work stoppages, liability exposure, and potential regulatory penalties. Always confirm locate tickets are current before ground disturbance.

Protocols and regulatory requirements for protecting workers in excavations deeper than 1.2 metres. Subcontractors must implement shoring, sloping, or trench boxes before workers enter. Non-compliance can result in stop-work orders, fines, and liability on your contract.

Mandatory government deductions withheld from employee wages, including CPP, EI, and income tax. Subcontractors with direct employees must remit these to the CRA on a set schedule. Misclassifying workers as independent contractors to avoid payroll tax can trigger costly audits.
