BOHS and OHTA Training Courses in South Africa: Your Complete Guide to Occupational Hygiene Certification and Career Growth 

Introduction to Occupational Hygiene Training 

Occupational hygiene is a critical scientific discipline focused on protecting the health and well-being of workers by identifying, evaluating, and controlling workplace hazards. These hazards may include chemical exposures, dust, fumes, vapours, noise, biological agents, and physical stressors such as heat and vibration. 

In South Africa and globally, occupational health risks are increasingly under scrutiny due to stricter legislation, growing awareness of long-term health effects, and the need for organisations to ensure compliance with workplace health and safety regulations.  

As a result, there is a growing demand for qualified occupational hygiene professionals equipped with the knowledge and practical skills to manage these risks effectively. 

One of the most recognised pathways into occupational hygiene is through structured training programmes offered by the British Occupational Hygiene Society (BOHS) and the Occupational Hygiene Training Association (OHTA). These organisations provide internationally recognised courses that support both entry into the field and ongoing professional development. 

What Are BOHS and OHTA Training Courses? 

BOHS and OHTA training courses are globally recognised programmes designed to provide individuals with the technical knowledge and practical understanding required to identify, assess, and control occupational health hazards. 

In South Africa, both BOHS and OHTA qualifications are recognised by the Southern African Institute for Occupational Hygiene (SAIOH). These courses form an important part of the professional development pathway for individuals seeking registration in occupational hygiene. 

A key advantage of BOHS and OHTA training is that the courses are aligned and equivalent in structure and content. For example: 

1. BOHS M200 – Basic Principles of Occupational Hygiene is equivalent to  
2. OHTA 201 – Basic Principles of Occupational Hygiene  

This alignment allows learners to choose a training provider while ensuring the qualification remains internationally relevant and recognised. 

These courses are widely utilised across multiple industries and professions, including: 

1. Health and Safety Officers  
2. Environmental Health Practitioners  
3. Safety Managers and Risk Practitioners  
4. Mine Ventilation Officers (MVOs)  
5. Mining Occupational Hygiene Officers  
6. Occupational Health Nurses and Medical Practitioners  
7. Environmental Scientists and Consultants  

Because of their international recognition, BOHS and OHTA qualifications are valuable not only in South Africa but also across Africa, the Middle East, Europe, Asia, Australia, and America. 

Why Occupational Hygiene Training Is Important 

Workplace hazards are often invisible and may not cause immediate harm, making them more difficult to identify and control compared to safety risks. Long-term exposure to hazardous substances such as silica dust, solvents, welding fumes, and noise can lead to chronic illnesses, including respiratory diseases, hearing loss, neurological conditions, and occupational cancers. 

Occupational hygiene training provides professionals with the ability to: 

1. Recognise workplace hazards before they cause harm. 
2. Understand exposure pathways and health effects. 
3. Measure and assess exposure levels accurately. 
4. Implement effective control measures. 
5. Ensure compliance with occupational health legislation. 

Employers have a legal responsibility under the Occupational Health and Safety Act to provide a safe working environment, including proper training, information, and supervision. BOHS and OHTA training directly supports this requirement by equipping employees and professionals with the competence needed to manage occupational health risks effectively. 

How to Become an Occupational Hygienist in South Africa 

In South Africa, occupational hygiene professionals register with the Southern African Institute for Occupational Hygiene (SAIOH), which recognises three progressive levels of professional registration. 

Occupational Hygiene Assistant (OHA) 

This is the entry-level position in occupational hygiene. Individuals at this level typically support more experienced practitioners and perform basic tasks under supervision. 

Requirements include: 

1. Completion of BOHS M200 or OHTA 201 – Basic Principles of Occupational Hygiene  
2. Passing the occupational hygiene legal knowledge examination  

Responsibilities may include: 

1. Conducting basic exposure measurements  
2. Assisting with occupational hygiene surveys  
3. Handling and maintaining monitoring equipment  
4. Capturing and recording data  

This level provides a strong foundation for further development in the field. 

Occupational Hygiene Technologist (OHT) 

At this level, professionals are expected to work more independently and apply their knowledge in practical workplace scenarios. 

Key responsibilities include: 

1. Planning and conducting occupational hygiene surveys  
2. Measuring exposure to various stressors  
3. Interpreting monitoring results  
4. Recommending control strategies  

To progress to this level, individuals typically complete multiple BOHS or OHTA modules and gain relevant work experience. Competence is demonstrated through both training and practical application. 

Occupational Hygienist (OH) 

This is the highest level of professional registration and requires advanced knowledge, extensive experience, and demonstrated competence. 

Responsibilities include: 

1. Designing and managing occupational hygiene programmes  
2. Conducting complex risk assessments  
3. Advising organisations on legal compliance  
4. Developing exposure control strategies  
5. Mentoring junior professionals  

At this level, professionals play a strategic role in protecting worker health and ensuring organisational compliance. 

BOHS and OHTA Course Structure and Learning Pathway 

Foundation Course: BOHS M200 / OHTA 201 

The starting point for most learners is: 

BOHS M200 / OHTA 201 – Basic Principles of Occupational Hygiene 

This course introduces fundamental concepts, including: 

1. Types of workplace hazards  
2. Routes of exposure (inhalation, skin absorption, ingestion)  
3. Health effects of exposure  
4. Principles of exposure assessment  
5. Basic control measures  

This course is essential for anyone entering occupational hygiene and is often a prerequisite for more advanced modules. 

Specialist Modules in BOHS and OHTA 

After completing the foundational course, learners can progress to more specialised modules, such as: 

These modules provide deeper technical knowledge and are aligned with international best practices in occupational hygiene. 

How BOHS and OHTA Training Benefits Safety Officers 

Safety Officers often manage both safety and occupational health risks. However, occupational health hazards are typically more complex and less visible than immediate safety risks such as physical injuries. 

BOHS and OHTA training enhances the capability of Safety Officers by enabling them to: 

1. Identify occupational health hazards more effectively. 
2. Understand long-term exposure risks. 
3. Interpret occupational hygiene reports with confidence.

5. Recommend appropriate control measures. 

This additional expertise allows Safety Officers to take a more proactive approach to workplace health, rather than reacting to incidents after they occur. 

The Role of Mine Ventilation Officers (MVOs) and Why They Benefit from Training 

In the mining industry, Mine Ventilation Officers (MVOs) play a critical role in controlling airborne hazards such as dust, fumes, gases, and heat stress. 

Their responsibilities include: 

1. Designing and maintaining ventilation systems  
2. Monitoring air quality underground  
3. Controlling exposure to hazardous substances  
4. Ensuring compliance with occupational exposure limits  

BOHS and OHTA training is highly beneficial for MVOs because it provides a deeper understanding of: 

1. Exposure assessment techniques  
2. Health effects of airborne contaminants  
3. Monitoring strategies and sampling methods  
4. Interpretation of occupational hygiene data  

This knowledge enhances their ability to protect workers in high-risk mining environments. 

Does BOHS or OHTA Training Make You Competent? 

Competence in occupational hygiene is defined by a combination of knowledge, training, experience, and skills. 

While BOHS and OHTA training provide essential theoretical knowledge and structured learning, they do not automatically make a person fully competent to conduct independent occupational hygiene surveys. 

To achieve competence, individuals must also gain: 

1. Practical workplace experience  
2. Hands-on training with monitoring equipment  
3. Mentorship from experienced professionals  
4. Exposure to real-world occupational hygiene challenges
