📖 1. Basic Occupational Health Concepts

🔑 Key Concepts & Definitions

• Occupational risk: The possibility that a worker suffers harm because of working conditions.
• Working condition: Any characteristic of work that can influence the generation of occupational risks.
• Health: Health includes physical, mental and social well-being, not merely the absence of illness.

💡 Memory Hook

Work can protect health, but working conditions can also create risk.

📖 2. Safety Conditions and Workplace Hazards

📝 Essential Points

• The main safety conditions are:

  • workplaces
  • premises and installations
  • work equipment

• The highlighted hazards include:

  • falls on the same level
  • falls from a different level
  • blows or collisions against objects

• The course highlights heights of 3 m, 2.5 m in offices, and guardrails of 90 cm as safety values to remember.

💡 Memory Hook

Place → installation → equipment → fall or impact

📖 3. Environmental Agents and Exposure

🔑 Key Concepts & Definitions

• Illumination: Illumination is measured in lux, and the necessary level depends on factors identified in the course materials.

📝 Essential Points

• The course distinguishes:
  • physical agents
  • chemical agents
  • biological agents
  • procedures

💡 Memory Hook

P-C-B: physical, chemical, biological agents

📖 4. Noise, Vibrations and Radiation

🔑 Key Concepts & Definitions

• Hearing loss: Hearing loss, or hypoacusis, is identified as a possible damage caused by noise exposure.

📝 Essential Points

• The course distinguishes dB(A) and dB(C) and highlights the noise values 80 dB(A), 85 dB(A), 87 dB(A), 135 dB(C) and 140 dB(C).

• Hand-arm vibration mainly affects the hands and arms, whereas whole-body vibration affects the body as a whole; examples mentioned include boats, aircraft, trains, trucks, buses, shovels, excavators and machines.

• Ionizing radiation includes X-rays and gamma rays, whereas non-ionizing radiation includes examples such as mobile phones and microwaves.

💡 Memory Hook

Hand-arm vibration affects the hands, whereas whole-body vibration affects the entire body.

📖 5. Chemical and Biological Agents

★ Must-know

📌 Chemical agents can present hazards such as flammability, explosiveness, reproductive toxicity and mutagenicity, and they are identified through labels and pictograms.

📌 Biological agents are classified into groups 1, 2, 3 and 4, which must be distinguished from the six groups of occupational diseases.

Further detail

• Hepatitis B is given as an example of a disease caused by a biological agent and classified in occupational-disease Group 3.

💡 Memory Hook

Biological groups 1–4 are not the same as occupational-disease groups 1–6.

📖 6. Ergonomic and Psychosocial Risks

🔑 Key Concepts & Definitions

• Burnout syndrome: Burnout syndrome has three components: emotional exhaustion, depersonalization and low personal accomplishment.

📝 Essential Points

• The routes of entry are:
  • respiratory
  • digestive
  • dermal or cutaneous
  • parenteral

📌 Physical workload concerns bodily effort and can involve musculoskeletal disorders, lower-back pain, physical fatigue, injuries, postures and load handling, whereas mental workload concerns psychological demands.

📌 Mobbing is hostile or violent workplace conduct that is repeated and prolonged over time; one isolated incident is not sufficient, and a power relationship may exist but is not always required.

💡 Memory Hook

E-D-B: emotional exhaustion, depersonalization, low personal accomplishment.

📖 7. Occupational Damage and Accidents

★ Must-know

📌 An occupational disease results from occupational exposure, whereas a work accident is an accident connected with work.

• The six groups are:
  • chemical agents
  • physical agents
  • biological agents
  • inhalation of substances
  • skin diseases
  • carcinogenic agents

📌 An in itinere accident occurs during travel between home and work, whereas an accident in mission occurs during travel required by the job.

Further detail

• The course also identifies rescue accidents and intercurrent diseases as categories related to work accidents.

💡 Memory Hook

An occupational disease develops through exposure, whereas a work accident results from an accident.
