GHS (Globally Harmonized System of Classification and Labelling of Chemicals)

The restricted, secured zone of an airport beyond passenger screening. Subcontractors working airside — such as fuelling crews or ground maintenance teams — must hold valid airside passes and follow strict security protocols. Access is tightly controlled and non-compliance can result in immediate removal from site.

A documented safety plan addressing heat stress and cold exposure risks for workers in outdoor or industrial environments. Subcontractors may be required to submit a TRIIPP before mobilising crews to remote or extreme-climate worksites. It typically outlines monitoring procedures, acclimatisation schedules, and emergency response protocols.

The percentage of scheduled preventive maintenance tasks completed on time. High PM compliance protects subcontractors from liability and supports equipment uptime on client sites. Clients often audit PM records before renewing service contracts.

Subcontractors must secure reauthorization before continuing work to avoid unpaid labour exposure. Delays in reauthorization can stall field crews and disrupt project schedules.

A site policy that prohibits any detectable level of drugs or alcohol in workers. Subcontractors must ensure all personnel pass pre-access and random testing. Violations typically result in immediate removal from site and contract penalties.

A U.S. federal advisory body that recommends construction safety standards to OSHA. Subcontractors working on U.S. projects must follow regulations shaped by ACCSH guidance. Monitoring its updates helps field crews stay ahead of evolving site safety requirements.
