Engineered controls used to prevent cave-ins, collapses, or hazardous exposures at excavation and confined space sites, including shoring, trench boxes, sloping, and shielding. Required by regulation on any excavation deeper than 1.2 metres. Subcontractors are typically responsible for selecting and installing the correct system before workers enter.
Protective Systems
Related Terms
Utility Locate
ComplianceA pre-dig service that identifies and marks underground utilities before excavation begins. Subcontractors are typically required to obtain a locate before breaking ground. Failure to do so can result in liability for damages, project shutdowns, or regulatory fines.
PFAS (Per- and Polyfluoroalkyl Substances)
ComplianceA group of synthetic chemicals found in firefighting foams, protective gear, and some industrial fluids used on job sites. Subcontractors may face handling restrictions, disposal requirements, and liability exposure under evolving federal and provincial regulations. Always check site-specific PFAS protocols before mobilising, as non-compliance can result in fines or contract termination.
Egress
ComplianceAny designated exit route workers use to safely leave a worksite, confined space, or structure in an emergency. Subcontractors must identify and keep egress pathways clear before work begins. Site access plans and emergency response procedures must document egress routes.
Excavation Stand Down
ComplianceA mandatory halt to all digging and ground-disturbance work, typically ordered after a near-miss, incident, or safety concern. Subcontractors must stop operations immediately and await formal clearance before resuming. Expect delays to schedules and potential cost impacts if stand downs are not addressed in your contract terms.
Labour Law § 240 (scaffold Law)
ComplianceA New York State law holding property owners and general contractors strictly liable for gravity-related injuries on elevated worksites. As a subcontractor, you may share liability if you control the work where the injury occurs. Proper scaffold safety protocols and clear contract language are critical to managing your exposure.
HOP (Human and Organizational Performance)
ComplianceA safety framework recognising that human error is normal and systems should be designed to reduce its impact. For subcontractors, HOP shifts blame away from individual workers toward process and organisational failures. Clients may require HOP-aligned incident reviews and pre-task planning on their worksites.
