Occupational Illness

Dr. Mohie Bakinson – MCO/1 (CSM/3)

What Is An Occupational Illness?

Any work-related abnormal condition or disorder, other than one resulting from a work injury, caused by or mainly caused by exposures(Health hazards) at work.

When is an OH illness work related?

•Has an illness indeed occurred?

•Is causal agents/conditions present at work?

•Was employee exposed?

•Is exposure sufficient to cause illness?

•Is there any non-occupational exposure?

Occupational Illness - CRITERIAA) Has an illness clearly been defined?

B) Does it appear that the illness is caused or mainly caused by suspected agents or other conditions at work?

C) Are these suspected agents present ( or have they been present) in the work environment?

D) Was the ill employee exposed to these agents in the work environment?

E) Was the exposure to a sufficient degree and/or duration to result in the illness or condition?

F) Was the illness attributable mainly to a non- occupational exposure?

Classification of Occupational Illness

1. Infectious and Parasitic Diseases: malaria, food poisoning, infectious hepatitis, dysentery, lambliasis, legionnaire's disease

2. Skin Diseases and Disorders: contact dermatitis, allergic dermatitis, rash caused by primary irritants and sensitisers or poisonous plants, oil acne, chrome ulcers, chemical burns or inflammations.

3. Respiratory Conditions due to Dust or Toxic Agents: silicosis, asbestosis, pneumoconiosis, pneumonitis, (allergic) bronchitis, alveolitis, asthma, pharyngitis, rhinitis or acute congestion due to chemicals, dusts, gases, or fumes.

4. Poisoning (Systemic Effects of Toxic Materials): poisoning by lead, mercury, arsenic, cadmium, or other metals; poisoning by carbon monoxide, hydrogen sulphide, or other gases; poisoning by solvents; poisoning by pesticides; poisoning by other chemicals such as formaldehyde, plastics and resins.

5. Disorders due To Physical Agents (Other than Noise and Toxic Materials) Examples: heat-stroke, sunstroke, heat exhaustion and other effects of heat stress; freezing, frostbite and other effects of exposure to low temperatures; caisson disease; effects of ionising (isotopes, X-rays, radium) and non-ionising (welding flash, ultraviolet rays, microwaves, sunburn) radiation

Classification of Occupational Illness (continue)

6. Disorders associated with Repeated Trauma: synovitis, tenosynovitis, and bursitis; Raynaud's phenomenon; other disorders of the musculo-skeletal system and connective tissue associated with repeated trauma.

7. Cancers and Malignant Blood Diseases: mesothelioma; bladder cancer; leukemia and other malignant diseases of blood and blood forming organs

8. Disorders due to Mental Stress: tension headache, depression, neurosis, "stress", functional disorders of the gastrointestinal tract

9. Noise Induced Hearing Loss: definition and criteria for reporting are given in the SHC Noise Guide 1991.

10. Other Illnesses and Disorders: Benign tumours; eye conditions due to dust and toxic agents; other (non-malignant) diseases of blood and blood forming organs.

Occupational Illness (Why Reporting?)

•Health is line management responsibility

•Ideal extent of the problem

•Health data needed to manage performance

•Also what controls to put in place

Difference between OH illness and Injury

•Work injury is a case which results from a work accident or from exposure involving a single event. Single-incident concept!

•If the case resulted form something that was not instantaneous it is considered as an illness

Role of Supervisor/Line manager/HSE adviser

•They understand the definition of OH illness and will try to identify early cases

•Refer to medical officer for confirmation and reporting

•Reporting by Contractors
