NIOSH Safety and Health Officer (SHO) - Occupational Health (Malaysia) study plan

Map the four exam domains against your current knowledge and rank your weakest sub-areas in Occupational Health and Malaysian OSH legislation

Outline the structure of the Occupational Safety and Health Act 1994 (Act 514) including employer, employee and self-employed duties and the general duties framework

Define the hierarchy of control and explain where health-focused controls (elimination, substitution, engineering, administrative, PPE) sit relative to each other

Build a one-page glossary linking core toxicology terms (dose, exposure route, latency, dose-response) to workplace examples

Explain the routes of entry of workplace hazards (inhalation, ingestion, dermal absorption, injection) and the factors that change absorbed dose

Distinguish acute versus chronic health effects and relate them to exposure duration and latency

Describe how occupational exposure limits are set and used, and distinguish the roles of the Department of Occupational Safety and Health (DOSH) and other agencies

Interpret the purpose of biological monitoring and health surveillance in detecting early health effects

Identify the main occupational health hazards by agent class: chemical, physical, biological, ergonomic and psychosocial

Describe the health effects and control approach for the most common physical agents (noise, heat, vibration, ionising and non-ionising radiation)

List the key requirements for a noise risk assessment and explain the action levels commonly applied in Malaysian practice

Explain how ergonomic risk factors (repetition, force, posture, duration) contribute to musculoskeletal disorders

Summarise the notification and reporting duties that apply to occupational diseases, poisoning and accidents

Outline the structure and purpose of the Factories and Machinery Act 1967 and its relationship to Act 514

Explain the role and functions of DOSH, the National Institute of Occupational Safety and Health (NIOSH) and the Social Security Organisation (PERKESO) in occupational health

Describe the employee's right to remove themselves from imminent danger and the employer's duty to investigate incidents

Apply the hierarchy of control to at least three workplace scenarios and justify the chosen control level

Describe the principles of machine guarding and the main mechanical hazards (entanglement, shearing, cutting, crushing)

Explain safe systems for confined space entry, including atmospheric testing, permit-to-work and rescue arrangements

Outline electrical safety principles including isolation, lockout/tagout and earth leakage protection

Conduct a structured risk assessment using a likelihood-by-severity matrix and record the reasoning for each rating

Distinguish hazard identification, risk assessment, risk evaluation and risk control as separate steps in a management process

Explain the purpose and content of a permit-to-work system and when it is required

Describe the elements of an emergency preparedness and response plan for a typical workplace

Outline the Plan-Do-Check-Act cycle as applied to an OSH management system and list the core elements of a recognised management system standard

Describe the role of a safety and health committee and the duties of a safety and health officer under Malaysian law

Explain the purpose of auditing, inspection and performance monitoring, and distinguish leading from lagging indicators

Design a simple incident investigation process using a recognised causal analysis method

Complete two full-length timed practice papers and record your score by domain

Revisit the three weakest sub-areas identified in week 1 and close the gaps with targeted revision

Practise explaining legal duties and control decisions aloud in the format expected in scenario-based questions

Build a final one-page summary sheet of formulas, limits, legal citations and control hierarchies
