How to Identify and Reduce Risk of Occupational Hazards

Every worker deserves the right to work in a healthy and safe environment. Unfortunately, workplace hazards remain a significant problem in many industries, putting employees at risk of serious injury or even death. To mitigate these risks, companies need to entrust the task of reducing workplace hazards to competent, skilled professionals. Enter the Occupational Hygienist. In this article, we will explore the critical role that occupational hygienists play in identifying, assessing, and mitigating workplace hazards to prevent injuries, illnesses, and fatalities.

Identifying Workplace Hazards

The first responsibility of an occupational hygienist is to identify the potential health hazards that workers may encounter in the workplace. They do this through rigorous assessments of both the workplace environment and the specific work processes involved. Air quality testing, noise level analysis, and chemical exposure assessments are just some of the methods used by occupational hygienists to identify potential hazards. Once identified, occupational hygienists work with employers and other safety professionals to develop strategies to mitigate the identified hazards.

Assessing Health Risks

Once hazards have been identified, occupational hygienists need to assess the degree of risk that these pose to workers’ health. Factors such as the duration of exposure, concentration, and toxicity of hazardous agents are considered. This information is then used to develop a comprehensive risk assessment, which enables the establishment of the necessary controls for minimising or eliminating exposure. This may involve control measures such as using personal protective equipment, changing work processes or implementing monitoring programmes to identify exposures that can cause harm.

Developing Safety Strategies

Occupational hygienists play a key role in developing risk control strategies that enable employers to improve workplace safety conditions. These strategies may include implementing appropriate engineering controls to prevent the release of hazardous agents, employee training in the safe handling of hazardous substances, and creating safety policies that provide guidelines for the handling of hazardous chemicals or other toxic substances. Occupational hygienists also provide recommendations to employers for equipment and safety procedures to ensure compliance with applicable safety requirements.

Assessing the Effectiveness of Control Measures

One of the final and most important tasks of the occupational hygienist is to determine whether the safety measures implemented are effective in controlling the identified hazards. This may involve monitoring workplace air quality, noise levels or measuring exposure levels of hazardous agents. The aim is to confirm that controls are working effectively, and no further actions are required. Occupational hygienists may also evaluate the level of compliance with safety procedures within the workplace or in compliance with applicable safety regulations.


The role of the occupational hygienist is critical in keeping workplaces safe and healthy for employees. These professionals identify potential hazards in the workplace, assess the health risks for employees, develop safety strategies that control or eliminate exposure, and evaluate the effectiveness of those strategies. By doing this, occupational hygienists help keep workers healthy, prevent illness and injury and ultimately, save lives. Employers and safety professionals should prioritize the engagement of qualified and competent occupational hygienists in the management of workplace safety risks.
