An occupational lung illness caused by inhaling crystalline silica dust during drilling, sandblasting, or concrete work. Subcontractors must implement exposure controls and monitoring to meet regulatory requirements. Failure to protect workers can result in serious liability and lost contracts.

An official work request issued before any ground disturbance, requiring underground utilities to be marked out. Subcontractors must have an active locate ticket on site before excavation begins. Working without one can result in fines, liability, or contract termination.

Mandatory safety systems used to prevent trench walls from collapsing on workers during excavation. Common methods include shoring, sloping, and trench boxes. Subcontractors are legally responsible for implementing compliant cave-in protection before workers enter any trench deeper than 1.2 metres.

Subcontractors must ensure certified RT technicians and proper radiation safety protocols are in place. Clients often require RT sign-off before authorising pressure testing or commissioning work.

A mandatory stop in work where a client or inspector must review and sign off before the subcontractor can proceed. Missing a hold point can void certifications or trigger costly rework. Always confirm hold points during project kickoff to avoid schedule delays.
