32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Hierarchy of controls
- A ranked list of hazard control measures from most to least effective: elimination, substitution, engineering controls, administrative controls, and personal protective equipment.
- Incidence rate formula
- The number of recordable injury or illness cases multiplied by 200,000, divided by total hours worked by all employees during the period.
- Internal responsibility system
- The legal principle that employers, supervisors, and workers share responsibility for workplace health and safety, with defined duties for each party.
- Right to refuse work
- A worker's legal right to refuse work they believe is unsafe, triggering an investigation process and protection from discipline for exercising the right.
- Risk assessment
- The process of evaluating the likelihood and severity of harm from identified hazards to determine risk levels and prioritize controls.
- Residual risk
- The level of risk that remains after controls have been implemented, which must be evaluated against the organization's risk tolerance.
- ALARP principle
- As Low As Reasonably Practicable: risk should be reduced until further reduction is grossly disproportionate to the benefit achieved.
- Job hazard analysis
- A systematic method of breaking a job into steps, identifying hazards at each step, and specifying controls before work begins.
- Time-weighted average
- An exposure metric calculated by summing the products of concentration and time for each task and dividing by the total exposure period.
- Occupational exposure limit
- A regulatory or advisory limit on the concentration of a hazardous agent in workplace air, typically expressed as an 8-hour TWA.
- Biological monitoring
- Measurement of a substance or its metabolite in body fluids or tissues to assess total absorbed dose from all exposure routes.
- Personal breathing-zone sampling
- Air sampling conducted in the worker's breathing zone to estimate inhalation exposure, preferred over area sampling for compliance purposes.
- Health surveillance
- A planned program of periodic health assessments for workers exposed to specific hazards, designed to detect early signs of work-related disease.
- Pre-placement medical examination
- A baseline health assessment conducted before job placement to confirm fitness for duty and establish reference data for future surveillance.
- Fitness for work
- An individualized determination that a worker can safely perform the essential duties of a job, with or without accommodation.
- Audiometric testing
- Hearing tests conducted at defined intervals for workers exposed to noise, used to detect early hearing loss and evaluate control effectiveness.
- Root cause analysis
- A structured method to identify the underlying systemic causes of an incident, beyond immediate causes, using tools such as 5 Whys or fishbone diagrams.
- Emergency response plan
- A documented set of procedures for responding to emergencies, including alarms, evacuation, roles, and communication, tested through drills.
- Corrective action tracking
- A system for assigning, monitoring, and verifying completion of actions to address identified deficiencies and prevent recurrence.
- Incident investigation
- A systematic process to determine the sequence of events, causes, and contributing factors of an incident to prevent recurrence.
- Training needs analysis
- A process to identify the gap between required and current competencies for each role, used to design targeted training.
- Competency-based training
- Training designed around observable performance criteria, with assessment of the learner's ability to demonstrate required skills.
- Kirkpatrick evaluation model
- A four-level framework for evaluating training effectiveness: reaction, learning, behavior, and results.
- Safety orientation
- Mandatory introductory training for new, young, returning, or contract workers covering workplace hazards, controls, and emergency procedures.
- Informed consent
- Voluntary agreement to participate in health surveillance or research after understanding the purpose, risks, benefits, and alternatives.
- Confidentiality
- The ethical and legal obligation to protect personal health information from unauthorized access, use, or disclosure.
- Leading indicators
- Proactive measures of prevention activities, such as training completion and hazard reports closed, that predict future safety performance.
- Lagging indicators
- Reactive measures of past outcomes, such as injury rates and lost-time claims, used to monitor trends but not predict future events.
- Management review
- A planned, periodic evaluation of the OHS management system by top management to ensure its continuing suitability, adequacy, and effectiveness.
- Due diligence
- A legal defence requiring the employer to demonstrate that all reasonable steps were taken to prevent an incident.
- Joint health and safety committee
- A committee with worker and employer representatives that identifies hazards, reviews incidents, and makes recommendations to improve workplace safety.
- Program evaluation
- A systematic assessment of OHS program implementation and outcomes using process and outcome measures to guide improvement.
