Chapter 6. Fundamentals of occupational hygiene and physiology
34 topics with concise breakdowns: definitions, key facts, and class questions.
This section focuses on the interaction between humans and the industrial working environment. Here we examine how work processes affect the body, study occupational physiology, the hygienic classification of working conditions, and employee protection methods—ranging from sanitary engineering systems to personal protective equipment (PPE).
The material is conventionally divided into two major blocks. The first covers occupational hazards: microclimate, noise, infrasound and ultrasound, all types of vibration and radiation (EMF, lasers, ultraviolet light). The second block is devoted to industrial toxicology and occupational medicine. You will study in detail the mechanisms of development and clinical presentation of occupational diseases—from pneumoconioses and COPD to poisonings with lead, mercury, carbon monoxide, pesticides, and irritants.
During practical classes and examinations, examiners are most rigorous regarding the hygienic classification of working conditions, criteria for diagnosing vibration-induced disease and sensorineural hearing loss, as well as the pathogenesis of specific poisonings (especially methemoglobin formers and heavy metals). A solid understanding of these topics is the absolute foundation for comprehending occupational medicine.
It investigates how the work execution process itself and the surrounding industrial environment affect human health.
What is the main difference between an occupational disease and a work-related disease?
An occupational disease arises solely due to exposure to a specific harmful factor in the workplace (without it, the disease will not develop). A work-related disease is a common illness that can also occur in everyday life, but poor working conditions increase the risk of its development and worsen its course.
How do optimal working conditions differ from harmful ones?
Optimal and permissible conditions ensure the complete preservation of the health of workers and their offspring throughout their lives. Harmful and hazardous conditions, conversely, can cause various health disorders, the severity of which can reach up to fatal outcomes.
How does an occupational disease differ from a work-related pathology?
An occupational disease is directly caused by harmful production factors. In work-related pathology, the disease is only associated with labor, and to confirm the diagnosis, the influence of ecology, living conditions, and genetics must be excluded.
Which types of electromagnetic fields are classified as occupational physical factors?
These include non-ionizing fields and radiation, electrostatic fields, static magnetic fields (including geomagnetic), as well as electric and magnetic fields of industrial frequency and radio frequency range.
