OSHAD Practitioner Exam cheat sheet

OSHAD (Abu Dhabi Occupational Safety and Health Center) system is mandatory for all entities in the Emirate of Abu Dhabi; compliance is regulated by the Abu Dhabi Occupational Safety and Health System Framework (OSHAD-SF).

OSHAD-SF comprises 7 elements: Policy, Planning, Implementation, Evaluation, Improvement, Management Review, and Contract Management.

Element 1 (Policy): requires a documented OSH policy signed by top management, covering commitment to OSH, compliance with legal requirements, and continual improvement.

Element 2 (Planning): includes hazard identification, risk assessment, legal and other requirements, and OSH objectives and targets.

Element 3 (Implementation): covers resources, roles, responsibilities, training, communication, documentation, operational control, and emergency preparedness.

Element 4 (Evaluation): includes performance monitoring, incident reporting, investigation, and internal audits.

Element 5 (Improvement): includes corrective and preventive actions, and management review (Element 6) for continual improvement.

Element 7 (Contract Management): requires OSH requirements to be included in contracts and contractor OSH management.

OSHAD-SF requires registration of OSH practitioners and approval of OSH advisors; entities must appoint a qualified OSH practitioner.

Risk = Severity × Likelihood (or Probability × Consequence). A risk matrix with 5x5 levels is commonly used; risk score determines risk level (e.g., low, medium, high, extreme).

Hierarchy of controls: Elimination, Substitution, Engineering controls, Administrative controls, PPE. Use in that order of effectiveness.

Hazard identification methods include: workplace inspections, job safety analysis (JSA), hazard and operability study (HAZOP), failure mode and effect analysis (FMEA), and task-based risk assessment.

Risk assessment must be conducted by competent persons; results must be documented, communicated, and reviewed periodically or after changes.

ALARP principle: risks should be reduced to As Low As Reasonably Practicable.

Residual risk is the risk remaining after controls are applied; it must be acceptable before work proceeds.

Dynamic risk assessment is required for non-routine tasks or changing conditions.

Risk register is a tool to record hazards, risks, controls, and responsible persons; it must be maintained and updated.

Hazard reporting systems must be in place to encourage workers to report hazards without fear of reprisal.

Incidents include: near misses, first aid cases, medical treatment cases, lost time injuries, restricted work cases, and fatalities.

Incident reporting: all incidents must be reported immediately to the supervisor and OSH practitioner; serious incidents must be reported to OSHAD and relevant authorities within specified timeframes (e.g., 24 hours for fatalities).

Incident investigation aims to identify root causes, not to assign blame. Use methods like 5 Whys, Fishbone diagram, or TapRooT.

Investigation steps: secure scene, gather evidence, interview witnesses, identify immediate and root causes, recommend corrective actions, and follow up.

Emergency preparedness: emergency response plan (ERP) must cover fire, chemical spill, medical emergency, natural disasters, and security threats.

Emergency drills must be conducted at least annually (or more frequently as required) and evaluated for effectiveness.

Emergency equipment (fire extinguishers, first aid kits, spill kits) must be inspected and maintained regularly.

Emergency assembly points and evacuation routes must be clearly marked and communicated to all workers.

Post-incident review should lead to updates in risk assessments, procedures, and training.

Occupational health hazards include: chemical, physical (noise, heat, radiation), biological, ergonomic, and psychosocial.

Occupational exposure limits (OELs) are set for airborne contaminants; exposure must not exceed the 8-hour time-weighted average (TWA) or short-term exposure limit (STEL).

Heat stress management: use WBGT index, provide cool drinking water, rest breaks, shade, and acclimatization for new workers.

Noise exposure: action level at 85 dB(A) for 8 hours; hearing protection required above 85 dB(A), and hearing tests for exposed workers.

Respiratory protection: use appropriate respirators (e.g., N95, half-face, full-face) with fit testing and medical evaluation.

Worker welfare: adequate sanitation, potable water, rest areas, and accommodation standards as per OSHAD requirements.

Health surveillance: pre-employment, periodic, and exit medical examinations for workers exposed to specific hazards.

Ergonomics: assess manual handling tasks, provide mechanical aids, and train workers in proper lifting techniques.

Biological hazards: implement infection control, vaccination, and hygiene measures for at-risk workers.

High-risk activities include: work at height, confined space entry, excavation, lifting operations, hot work, electrical work, and demolition.

Work at height: fall protection required above 2 meters; use guardrails, safety nets, or personal fall arrest systems.

Confined space entry: requires permit, atmospheric testing (O2, LEL, H2S, CO), ventilation, standby person, and rescue plan.

Excavation: shoring, sloping, or benching required for trenches deeper than 1.2 meters; inspect daily and after rain.

Lifting operations: use certified equipment, qualified operators, and a lift plan for critical lifts; maintain exclusion zones.

Hot work: permit required; fire watch, fire extinguisher, and removal of combustibles within 10 meters.

Contractor management: pre-qualification, OSH requirements in contracts, contractor induction, supervision, and performance monitoring.

Permit-to-work (PTW) system: for high-risk work, ensuring hazards are identified and controls are in place before work starts.

Construction site safety: site layout, traffic management, housekeeping, and welfare facilities.

Fire triangle: fuel, oxygen, heat. Fire extinguisher classes: A (solid combustibles), B (flammable liquids), C (flammable gases), D (metals), E (electrical), F (cooking oils).

PASS technique: Pull, Aim, Squeeze, Sweep for using fire extinguishers.

Fire prevention: control ignition sources, store flammables properly, maintain electrical equipment, and conduct fire risk assessments.

Chemical safety: maintain Safety Data Sheets (SDS) for all hazardous chemicals, label containers, and provide training.

Chemical storage: segregate incompatible chemicals, use secondary containment, and ensure proper ventilation.

Hazardous waste management: follow the waste hierarchy (prevent, reduce, reuse, recycle, recover, dispose).

Spill response: use spill kits, contain the spill, protect drains, and dispose of waste properly.

Environmental protection: prevent pollution, manage emissions, and comply with environmental regulations.

Fire detection and alarm systems, and emergency lighting must be inspected and maintained regularly.

Leading indicators: proactive measures such as training hours, safety audits, hazard reports, and near-miss reporting.

Lagging indicators: reactive measures such as incident rates, lost time injury frequency rate (LTIFR), and severity rate.

LTIFR = (Number of lost time injuries × 1,000,000) / Total hours worked.

Audits: systematic review of OSH management system; internal audits at planned intervals, and external audits by OSHAD or third parties.

Inspection: routine workplace checks to identify hazards and non-compliance; use checklists and record findings.

Corrective and preventive actions (CAPA): address root causes, assign responsibility, and track to closure.

Management review: top management reviews OSH performance, audit results, and objectives to ensure continual improvement.

Benchmarking and performance indicators should be SMART (Specific, Measurable, Achievable, Relevant, Time-bound).

Worker participation in monitoring: encourage reporting and involvement in inspections.

Training needs analysis (TNA) identifies gaps in knowledge and skills required for safe work.

OSH induction training must be provided to all new workers, contractors, and visitors before site access.

Competency-based training: ensure workers have the necessary knowledge, skills, and attitude to perform tasks safely.

Communication methods: toolbox talks, safety meetings, notice boards, emails, and signage.

Safety culture: a positive safety culture is characterized by management commitment, worker involvement, and open communication.

Behavior-based safety (BBS) programs focus on observing and reinforcing safe behaviors.

Training records must be maintained and include date, content, trainer, and participant names.

Awareness campaigns: use posters, campaigns, and incentives to promote OSH.

Effective communication is two-way; encourage feedback and reporting.

OSH practitioners must maintain competence through continuous professional development (CPD).

Ethical principles: integrity, objectivity, confidentiality, and avoidance of conflicts of interest.

Practitioners must report hazards and incidents truthfully and not conceal information.

Professional codes of conduct: adhere to OSHAD code of ethics and relevant professional bodies.

Confidentiality: protect worker health information and business sensitive data.

Practitioners should advocate for worker safety and health, and influence management decisions.

Whistleblowing: report unethical or unsafe practices to appropriate authorities.

Collaboration: work with other professionals, workers, and management to improve OSH.

Legal accountability: practitioners may be held liable for negligence in performing their duties.
