01Health and Safety Foundations and Legal Framework
This domain tests whether you can connect legal duties to daily supervision: employer obligations, worker rights, safety-officer functions, OSH committee roles and reporting routes. In the Philippine framework, RA 11058 and its IRR, DOLE Department Order 198, operate with the OSH Standards; ISO 45001 is a management-system reference, not a statute.
305 words, about 2 min02Health and Safety Management Systems
This domain examines whether you understand a management system as a cycle, not a folder of documents. ISO 45001 uses Plan-Do-Check-Act: context, leadership and worker participation, planning, support, operation, performance evaluation and improvement.
278 words, about 1 min03Risk Assessment and Control
This domain tests the difference between a hazard and a risk, and whether you can select controls in the right order. A hazard is a source of harm; risk combines likelihood and severity.
270 words, about 1 min04Workplace Hazards and Controls
This domain tests recognition and control of physical, chemical, biological, ergonomic and psychosocial hazards. Physical hazards include noise, vibration, heat, electricity, falls and confined spaces.
289 words, about 1 min05Incident Investigation, Recording and Reporting
This domain tests whether you can separate an accident, a near miss and a dangerous occurrence, preserve evidence, find causes and meet reporting duties. An accident causes harm; a near miss could have caused harm; a dangerous occurrence is a specified high-potential event.
278 words, about 1 min06Emergency Preparedness and Response
This domain tests whether you can turn emergency scenarios into practical arrangements: alarm, evacuation, assembly, accounting for people, first aid, fire response, spill control and communication. The plan must match the site’s hazards and be understood by workers, contractors and visitors.
249 words, about 1 min07Monitoring, Auditing and Performance Measurement
This domain tests whether you can distinguish monitoring, inspection and audit, and choose indicators that drive improvement. Monitoring checks ongoing conditions or exposure; inspections examine physical conditions and behaviours; audits systematically evaluate conformity with a standard or management system.
245 words, about 1 min08Workforce Health and Wellbeing
This domain tests the difference between occupational health protection and broader wellbeing, and whether you can apply both without breaching confidentiality. Health surveillance is required where exposure could cause identifiable disease or health effects, such as noise, vibration, respiratory sensitisers or certain chemicals.
241 words, about 1 min09Contractor and Supply Chain Management
This domain tests whether you can manage shared risk when work is performed by contractors or suppliers. The host employer cannot simply transfer all responsibility by contract.
255 words, about 1 min10Environmental and Sustainability Considerations
This domain tests whether you can connect OSH practice with environmental aspects and impacts. An aspect is an activity, product or service that interacts with the environment; an impact is the resulting change, such as pollution, resource depletion or waste.
