It involves identifying, assessing, and controlling workplace hazards to prevent work-related illnesses and injuries. The principles and concepts of occupational hygiene are based on scientific and engineering disciplines, and it is essential for compliance with health and safety legislation and regulations.
Assessment of Hazards
As occupational hygienists, we are responsible for identifying and assessing the hazards present in the workplace. This involves a systematic approach to identifying potential risks to the health and safety of workers and others in the workplace.
Physical Hazards
Physical hazards are those that can cause harm to the body through physical means. These can include noise, vibration, radiation, temperature extremes, and ergonomic hazards. We use various methods to assess physical hazards, including noise dosimetry, vibration measurement, and thermal stress monitoring.
Chemical Hazards
Chemical hazards are those that can cause harm to the body through exposure to chemicals. These can include gases, vapours, dusts, and liquids. We use various methods to assess chemical hazards, including air sampling, wipe sampling, and personal exposure monitoring.
When assessing chemical hazards, it is important to consider both acute and chronic exposure. Acute exposure can cause immediate harm, while chronic exposure can cause long-term health effects such as cancer, respiratory diseases, and neurological disorders.
Biological Hazards
Biological hazards are those that can cause harm to the body through exposure to microorganisms such as bacteria, viruses, and fungi. These can include infectious diseases, allergies, and toxic reactions. We use various methods to assess biological hazards, including air sampling, surface sampling, and personal exposure monitoring.
When assessing biological hazards, it is important to consider the route of exposure, such as inhalation, ingestion, or skin contact. It is also important to consider the susceptibility of the individual, such as those with weakened immune systems or allergies.
In conclusion, the assessment of hazards is a critical component of occupational hygiene. By identifying and assessing potential risks, we can take appropriate measures to protect the health and safety of workers and others in the workplace.
Control Measures
As occupational hygienists, we implement control measures to prevent or limit exposure to hazardous substances in the workplace. The objective of implementing control measures is to prevent, or to adequately control, exposure to substances hazardous to health. We use a hierarchy of controls to determine which actions will best control exposures. The hierarchy of controls has five levels of actions to reduce or remove hazards. The preferred order of action based on general effectiveness is:
Preventive Strategies
- Elimination
- Substitution
- Engineering controls
- Administrative controls
- Personal protective equipment (PPE)
Elimination is the most effective control measure as it removes the hazard completely. Substitution involves replacing the hazardous substance with a less hazardous one. Engineering controls involve modifying the workplace to reduce exposure to the hazard, such as ventilation systems or enclosing the process. Administrative controls involve changing work practices or procedures to reduce exposure. PPE is the least effective control measure as it only protects the individual wearing it.
Protective Equipment
When PPE is necessary, we ensure that it is appropriate for the hazard and the individual wearing it. PPE includes items such as gloves, respirators, and eye protection. We select PPE based on the hazard and the individual’s job tasks. We also ensure that the PPE is properly maintained, cleaned, and stored. It is important to note that PPE should only be used as a last resort after all other control measures have been implemented.
In summary, we implement a hierarchy of control measures to prevent or limit exposure to hazardous substances in the workplace. We prioritize control measures based on their effectiveness, with elimination being the most effective and PPE being the least effective. When PPE is necessary, we ensure that it is appropriate for the hazard and the individual wearing it.
Health Surveillance
As Occupational Hygienists, we understand the importance of Health Surveillance in protecting the health and wellbeing of workers. Health Surveillance is a systematic process of monitoring workers’ health, assessing their exposure to workplace hazards, and identifying any adverse health effects that may result from their work.
Monitoring Methods
Health Surveillance involves various monitoring methods, such as biological monitoring, medical surveillance, and exposure monitoring. Biological monitoring involves the measurement of substances or their metabolites in biological samples, such as blood, urine, or breath, to assess exposure to hazardous substances. Medical surveillance involves regular medical examinations, such as lung function tests, hearing tests, and skin assessments, to detect early signs of ill health. Exposure monitoring involves the measurement of hazardous substances in the air, water, or other media to assess the level of exposure of workers.
Health Risk Assessment
Health Surveillance also involves Health Risk Assessment, which is the process of identifying and assessing the risks to workers’ health from exposure to workplace hazards. Health Risk Assessment involves evaluating the likelihood and severity of harm to workers’ health, taking into account the nature, frequency, and duration of exposure, as well as the susceptibility of workers to harm. Health Risk Assessment helps to identify the appropriate measures to control exposure to workplace hazards and prevent adverse health effects.
In conclusion, Health Surveillance is a crucial component of Occupational Hygiene, helping to protect workers’ health and wellbeing by monitoring their exposure to workplace hazards and identifying any adverse health effects. By using various monitoring methods and conducting Health Risk Assessment, we can ensure that workers are protected from the harmful effects of workplace hazards.
Legislation and Standards
Occupational hygiene is governed by various regulations and standards to ensure the safety and health of workers in the workplace. In this section, we will discuss the UK regulations and international standards that are relevant to occupational hygiene.
