| Target Participants | Sterilization operators, engineers, EHS personnel, maintenance staff, QA/RA personnel, supervisors, managers, auditors, and technical specialists. |
| Methodology | Interactive lecture, guided discussion, case study review, scenario exercises, facilitator-led interpretation of requirements, and knowledge assessment. |
| Training Language | English (with practical explanation in Bahasa Malaysia where required). |
| Class Size | Recommended 10 to 25 participants for effective interaction. |
| Assessment Method | Pre-training diagnostic questions, continuous participation, scenario-based exercises, and post-course assessment. |
| Passing Mark | Minimum 70% for post-course knowledge assessment. |
Learning Objectives
- Explain the role of EO sterilization and the key properties of EO gas relevant to medical device processing.
- Identify occupational health risks, exposure routes, and common leakage or release scenarios in EO sterilization facilities.
- Interpret core safety and environmental requirements applicable to EO operations, including process, workplace, and emission-control perspectives.
- Describe engineering controls, administrative controls, monitoring systems, and PPE requirements used to reduce EO exposure.
- Apply practical response principles for EO alarms, leaks, accidental exposure, incident reporting, and corrective actions.
- Recognise good practices for environmental emission management, compliance monitoring, and continual improvement of EO safety systems.
Learning Outcomes
At the end of the programme, participants should be able to:
- describe EO gas hazards and their relevance to worker safety and environmental protection;
- identify critical control points in pre-conditioning, sterilization, aeration, maintenance, and cylinder-handling activities;
- differentiate between area monitoring, personal exposure monitoring, and leak-detection applications;
- recommend suitable control measures for EO risk reduction and compliance improvement; and
- respond more effectively to EO-related incidents through structured emergency and reporting practices.
Detailed Course Content
Module 1: Introduction to EO Sterilization and EO Gas Properties

Module 2: EO Gas Exposure Risks in Sterilization Facilities
Participants review where EO exposure can arise in real facility conditions and how work activities can influence the magnitude and likelihood of exposure.
- Common points of EO gas leakage and release
- Routes of exposure: inhalation, skin and eyes
- Risk scenarios during pre-conditioning, sterilization, aeration and maintenance
- Typical high-risk tasks and human-factor considerations
Module 3: Regulatory and Safety Standards
Participants gain awareness of the regulatory and standards framework that supports safe EO operations and compliance obligations.
- Overview of applicable standards and regulations
- ISO 11135:2014 overview relevant to EO sterilization safety and process control
- Occupational exposure concepts such as PEL, STEL and action levels
- Environmental compliance expectations, emissions management, and local regulatory responsibilities
Module 4: Engineering and Administrative Controls
Participants examine the layered control strategy required to prevent, detect and manage EO gas release and exposure.
- Facility design considerations for chambers, ventilation and aeration
- Local exhaust ventilation (LEV) and negative-pressure zoning
- EO gas abatement systems such as catalytic converters and scrubbers
- Safe storage, segregation and handling of EO cylinders
- Administrative controls including permits, access control, SOPs and competency
Module 5: Monitoring and Detection of EO Gas
Participants learn how monitoring data supports exposure control, compliance demonstration, and timely intervention.
- EO gas detection technologies and equipment
- Personal exposure monitoring versus area monitoring
- Leak-detection protocols and alarm systems
- Data logging, documentation and trending for compliance
Module 6: Personal Protective Equipment (PPE) and Safe Work Practices
Participants understand the role and limitations of PPE, along with safe work practices that complement engineering controls.
- Selection and use of PPE for EO environments
- Worker training on safe handling and emergency practices
- Entry and exit protocols for EO-related areas
- Safe work instructions and permit-to-work considerations
Module 7: Emergency Preparedness and Incident Response
Participants practise structured thinking for prompt and safe response to EO incidents, including escalation and reporting.
- Responding to EO leaks, alarms and accidental exposure
- Evacuation principles and first-aid response
- Spill containment and decontamination concepts
- Incident reporting, investigation, root-cause analysis and CAPA
Module 8: Environmental Control and Emission Compliance
Participants review how EO facilities manage off-gas treatment, emissions, and environmental responsibilities.
- EO emission sources and control technologies
- Stack testing, emission reporting and compliance verification
- Waste EO management and destruction practices
