Crystalline Silica Rule

A documented system requiring subcontractors to isolate and de-energise equipment before maintenance or service work begins. It defines lockout/tagout procedures, worker responsibilities, and verification steps. Prime contractors often audit subcontractor programs before awarding site access.

A 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.

The process of controlling airborne particulates on worksites using water trucks, chemical agents, or barriers. Subcontractors may be contractually responsible for dust suppression on access roads, laydown yards, or excavation sites. Failure to comply can result in stop-work orders or back-charges from the prime contractor.

A formal written authorisation required before performing any work that produces heat, sparks, or open flame on a job site. Subcontractors must obtain this permit before welding, cutting, or grinding near flammable materials. Site supervisors issue and sign off on these permits, and work must stop if conditions change.

A physical or mechanical system that prevents uncontrolled flow of fluids from a wellbore. Subcontractors working on or near wells must verify barriers are in place before starting work. Barrier failures can trigger stop-work obligations and regulatory reporting requirements.

A credentialed professional who assesses and controls workplace health hazards such as chemical exposure, noise, and air quality. Subcontractors may be required to retain or consult a CIH to meet site entry or regulatory requirements. Their sign-off can be mandatory before work begins in confined spaces or hazardous environments.
