Sloping (excavation)
Related Terms
HSE (Health, Safety, and Environment)
ComplianceA framework governing safe work practices, environmental protection, and worker health on job sites. Subcontractors must meet client HSE standards to qualify for and maintain contracts. Non-compliance can result in work stoppages, site removal, or lost future opportunities.
TRIIPP (Temperature-related Injury and Illness Prevention Plan)
ComplianceA 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.
Airside
ComplianceThe 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.
Silica Disease
ComplianceAn 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.
PAPR (Powered Air-purifying Respirator)
ComplianceA battery-powered respirator that uses a blower to push contaminated air through filters before the worker breathes it. Subcontractors working in refineries, confined spaces, or around hazardous chemicals are often required to supply their own PAPR units. Fit-testing and training records must be maintained to meet occupational health regulations on site.
Heat Stress
ComplianceA condition where the body cannot cool itself fast enough during hot or humid work conditions. It poses serious health and liability risks for subcontractors with outdoor or confined-space crews. Unmanaged heat stress can trigger site shutdowns and affect your compliance standing with the prime contractor.
