OSHAD Practitioner Exam key terms

The Abu Dhabi government body that sets and oversees occupational safety and health requirements for employers and projects in the emirate, issuing the system manual, technical guidance and audit criteria used by practitioners.

The core document published by OSHAD that defines the elements, roles and expectations of the emirate's OSH management system, including policy, planning, implementation, evaluation and management review requirements.

A competent person registered or recognized under the Abu Dhabi framework to develop, implement, monitor and improve an entity's OSH management system and to advise on compliance with OSHAD requirements.

A structured set of interrelated policies, plans, procedures and resources an organization uses to control OSH risks, meet legal duties and continually improve performance, typically following the plan-do-check-act cycle.

A ranked order of risk-reduction measures, from most to least reliable: eliminate the hazard, substitute it, engineer controls, apply administrative controls, and finally use personal protective equipment.

A systematic process of identifying hazards, evaluating the likelihood and severity of harm, and deciding whether existing controls are adequate or further action is required.

The process of recognizing sources or situations with potential to cause harm, covering physical, chemical, biological, ergonomic, psychosocial and environmental agents, before risk is evaluated and controlled.

Any source, condition or activity with the potential to cause injury, ill health, damage to property or harm to the environment, independent of how likely it is to do so.

The combination of the likelihood that a hazardous event occurs and the severity of the harm it could cause, often expressed as a score used to prioritize control measures.

A tool that plots likelihood against severity to assign a risk rating, helping practitioners rank hazards consistently and decide which require urgent action or escalation.

The level of risk that remains after existing or planned control measures have been applied, which must be judged tolerable before work proceeds.

A principle meaning risk should be reduced as low as reasonably practicable, balancing the cost, effort and difficulty of further controls against the improvement in safety they would deliver.

A formal written authorization that specifies the task, hazards, controls, isolation and time limits for high-risk work, and confirms that responsible persons have checked conditions before work starts.

A procedure for isolating energy sources and attaching locks and warning tags so equipment cannot be re-energized or started while maintenance or repair work is in progress.

Entry into an enclosed or partially enclosed space with restricted access that may contain hazardous atmospheres, requiring testing, ventilation, attendant standby and rescue arrangements before and during entry.

A document describing how a specific task will be carried out safely, including sequence of work, plant and materials, competent persons, control measures and emergency arrangements.

A technique that breaks a task into steps, identifies hazards at each step and records the controls to be applied, often used as a briefing tool before work begins.

An undesired event or near miss arising from work that caused or could have caused injury, ill health, property damage or environmental harm, and which must be reported and investigated.

An unplanned event that did not result in injury, illness or damage but had the potential to do so, making it a valuable warning signal for corrective action.

A structured method for tracing an incident back to underlying management, design or behavioral failures rather than stopping at the immediate cause, so that effective corrective actions can be set.

The systematic gathering and analysis of evidence about an incident to establish what happened, why it happened and what actions will prevent recurrence.

A measure taken to eliminate the cause of a detected nonconformity or incident and prevent it from happening again, tracked to completion and verified for effectiveness.

A documented set of arrangements covering emergency scenarios, alarm and evacuation procedures, roles, resources, communication and drills, designed to protect people and limit damage.

A planned rehearsal of an emergency response that tests procedures, communication and competence, and whose findings are used to improve the emergency plan.

The application of elimination, substitution, engineering controls, administrative controls and protective equipment specifically to chemical hazards, prioritizing safer substances and containment before reliance on PPE.

A standardized document providing hazard, composition, first-aid, handling, storage, exposure control and disposal information for a hazardous chemical, used to inform risk assessments and worker instruction.

Any substance or mixture classified as physically or health hazardous, such as toxic, corrosive, flammable or carcinogenic materials, which requires assessment and controlled handling in the workplace.

The marking of chemical containers with hazard pictograms, signal words and precautionary information so that users can identify risks and handle substances correctly.

A defined airborne concentration of a substance that workers should not be exposed to over a stated reference period, used to judge whether controls such as ventilation are adequate.

The discipline of anticipating, recognizing, evaluating and controlling workplace factors that may cause illness, including airborne contaminants, noise, heat and biological agents.

A planned program of medical checks or biological monitoring for workers exposed to specific health hazards, used to detect early signs of work-related ill health and trigger preventive action.

The amenities an employer must provide for workers' wellbeing, such as drinking water, sanitation, washing, rest areas, shelter from heat and suitable accommodation where required.

The physiological strain on the body from working in hot environments, managed through acclimatization, hydration, rest breaks, scheduling and monitoring to prevent heat illness.

Clothing or equipment worn by a worker to reduce exposure to hazards, such as helmets, gloves, respirators and hearing protection, used as the last line of defense.

A short, focused briefing delivered before or during work to communicate hazards, controls and expectations to the crew, encouraging questions and reinforcing safe behavior.

The shared values, attitudes and behaviors of an organization toward safety, reflected in how leaders act, how workers report problems and how lessons are learned.

Visible commitment by managers and supervisors to safety through their decisions, resourcing, site presence and modeling of expected behavior, which strongly shapes workforce attitudes.

A systematic, independent and documented examination of an OSH management system against defined criteria, producing findings, nonconformities and recommendations for improvement.

A routine, often shorter check of workplaces, plant or practices against requirements, used to detect unsafe conditions or behaviors and prompt immediate or planned corrective action.

A failure to meet a specified requirement, such as a legal duty, procedure or management system element, which must be recorded, corrected and followed up to prevent recurrence.

The ongoing process of enhancing OSH performance by setting objectives, measuring results, learning from findings and adjusting the management system accordingly.

A periodic, top-level evaluation of the OSH management system's suitability, adequacy and effectiveness, leading to decisions on resources, objectives and system changes.

The combination of training, qualifications, experience and demonstrated ability that enables a person to perform assigned OSH tasks safely and reliably.

The principles guiding an OSH practitioner's conduct, including honesty, integrity, objectivity, confidentiality, avoiding conflicts of interest and acting in the public interest when reporting risk.

The process of selecting, briefing, controlling and monitoring contractors so that their work meets the host organization's OSH requirements and interfaces safely with other activities.
