Fixed Ladder
ComplianceA permanently mounted ladder attached to a structure, vessel, or facility used to access elevated work areas. Subcontractors must ensure fixed ladders on their worksites meet provincial and federal safety standards before crews use them. Inspect for damage, proper cage guards, and fall arrest anchor points before starting elevated work.
API (American Petroleum Institute)
ComplianceThe leading industry organisation that develops technical standards, safety protocols, and equipment specifications that subcontractors must follow when working on oil and gas projects. API certifications and compliance with API standards are often mandatory requirements in service contracts and can affect your ability to bid on projects.
PUCO (Public Utilities Commission of Ohio)
ComplianceOhio's regulatory body overseeing utility construction and service work. Subcontractors performing pipeline, electrical, or gas utility projects in Ohio must comply with PUCO-mandated standards. Non-compliance can result in work stoppages or contract penalties.
Bonded Operator License
ComplianceA licence that requires the holder to carry a surety bond as financial assurance that they will meet regulatory obligations, meaning subcontractors and field service companies must maintain this bond coverage to legally operate certain equipment or perform specific scopes of work on a client's site. For subcontractors, holding a bonded operator licence is often a prerequisite for bidding on contracts, as it signals to operators and general contractors that financial accountability is in place if work standards or regulatory requirements are not met.
Well Integrity
ComplianceThe ability of a well to contain fluids and pressure without uncontrolled release. Subcontractors performing wellsite work must follow strict well integrity protocols to prevent blowouts or leaks. Failure to comply can result in contract termination and regulatory penalties.
PPE (Personal Protective Equipment)
ComplianceProtective gear — such as hard hats, steel-toed boots, high-visibility vests, gloves, and eye protection — that subcontractors and their crews are required to wear on oil & gas and construction sites to meet site-specific safety standards and regulatory obligations. As a subcontractor, ensuring your workers arrive on-site with proper, compliant PPE is typically your responsibility and a condition of maintaining your contract.
