Q

What are the overall objectives of occupational health services are embodied in five principles, the terminology of which is derived from that used to discuss the health for all concept, regarding occupational health?

A
The adaptive principle
The protection & prevention principle
The health promotion principle
The curative & rehabilitative principle
The primary health care principle

(i) The adaptive principle: Adapting work and the work environment to the capabilities of workers.
(ii) The protection and prevention principle: Protecting workers’ health against hazards at work.
(iii) The health promotion principle: Promoting the physical and psycho-social well-being of workers.
(iv) The curative and rehabilitative principle: Minimising the consequences of occupational hazards, accidents and injuries, and occupational and related diseases.
(v) The primary health care principle: Providing limited general health care services for workers at the workplace.

Q

What are the most important principles of an occupational hygiene programme?

A
  • It must be aligned with and designed around the actual nature of the organisation’s operations and processes (i.e. its reality).
  • It needs to be an ongoing, dynamic and organic programme based on the actual needs of the organisation,
  • The programme will require continuous data collection to identify and assess the levels of all stressors in the workplace.
  • A data storage system is needed that will permit the retrieval of information to effectively assess the relevance of the data being collected.
  • There needs to be a periodic and thorough review of worker exposure and health reports to detect possible new stressors and reassess known stressors where needed.
  • The programme must also serve as a retrospective record or archive of all stressors in the workplace and the controls thereof.
  • At all times, it needs to be executed professionally by all those required to ensure that occupational hygiene is addressed in the workplace.
  • Integration of occupational hygiene with the overall occupational health service and risk management programmes is critical so that all controls can be properly evaluated and changed as and when needed.

  9. Pneumonitis: An extensive accumulation of dust particles in the lungs together with the resultant tissue reaction is referred to as pneumonitis.
  10. Silicosis: Silicosis is a chronic disease that develops with over-exposure to silica dusts. It is characterised by generalised fibrotic changes, lung scars, shortness of breath and lessened capacity for work.
  11. Mesothelioma: Mesothelioma is characterised by masses of fibrous tissue that start to develop at the base of the lung and slowly progress upwards. The active lung tissue is replaced by inactive scar tissue that reduces the lung volume, resulting in shortness of breath and fatigue, and possible death.
  12. Chronic obstructive pulmonary disease (COPD): COPD is closely associated with cigarette smoking. This term is used to describe three inter-related disorders: chronic bronchitis, emphysema and chronic airflow limitation.
  13. Chronic bronchitis: Chronic bronchitis occurs due to the inflammation of airways and the resultant mucus gland hyperplasia.
  14. Emphysema: This condition can eventually develop due to the destruction of the gas exchange tissue of the lung as a consequence of a chronic inflammatory response due to environmental exposures.
  15. Contact dermatitis: Dust can also cause itching or irritation to the skin, which can become a chronic condition if not treated properly.
  16. Asbestosis: A long term inflammation and scarring of the lungs due to the prolonged exposure and inhalation of asbestos fibres

69
Q

Define Noise-induced hearing loss?

A

The principal health-related effect of noise exposure is known as noise-induced hearing loss. Excessive noise can destroy the ear’s ability to hear, and the result is long-term and irreversible (Chronic).

70
Q

What does IAQ stand for?

71
Q

Define ERW5?

A

Ventilation

72
Q

What are the two types of ventilation?

A
  • General ventilation (Blowing Action)

- Local exhaust ventilation (LEV).

73
Q

Explain general ventilation?

A

Reduces airborne concentrations of chemicals by diluting the workplace air with cleaner air from outside. General ventilation can effectively remove large amounts of hot or humid air, or dilute low concentrations of low toxicity contaminants. General ventilation does not eliminate exposure to airborne contaminants and is especially unsuitable for fumes or dusts.

74
Q

Explain a LEV system?

A

LEV removes the contaminant rather than diluting it. This type of ventilation is only effective if it is located close to the source of the hazard.

75
Q

A LEV system has five key components?

A
  • A fan or a blower that draws in contaminated air.
  • A hood that allows the effective capture of the contaminant.
  • A system of ducts that transport the contaminated air away from the workplace.
  • An air-cleaning device that removes the contaminants from the air.
  • A source of make-up air that replaces the air removed from the workplace.
76
Q

Define ERW2?

A

A
MSDs are the leading cause of disability for people in their working years. It affects both upper extremities and the lower back areas. They can be caused by frequently working in a way that puts stress on the body, such as:
- Gripping
- Kneeling
- Lifting
- Squatting
- Applying force
- Repetitive movement
- Bending
- Working overhead
- Twisting
- Using vibrating equipment
- Working in awkward positions
- Over-reaching
Some examples of MSDs are:
     • Nerve disorders
     • Neuro-vascular  disorders
96
Q

What is the Ergonomics/Manual handling Assessment?

A
In order to determine the risks and identify controls an ergonomics assessment should be conducted. During such an assessment, four main factors must be considered:
- Task
- Individual
- Load
- Environment 
(TILE)
97
Q

Explain Task with regards to manual handling assessment?

A

The task
Aspects to consider:
The task should be analysed to include all aspects, such as:
• the use of mechanical aids,
• the number of people involved,
• lifting techniques used,
• body posture,
• distance to carry or lift the load,
• excessive pulling and pushing,
• task done while seated,
• forceful exertions when using a piece of equipment or hand-tool,
• frequency of performing the task such as hitting a hammer for a long time and
• repeated or continuous contact with hard or sharp objects such as non-rounded desk edges or unpadded, narrow tool handles.
Other risk factors inherent in the job would include items such as work procedures, equipment, and workstation design.
These factors address the “how”, how is the task being done?
Controls: The task can be improved by changing the workstation, removal of obstacles, use of better lifting techniques, implementing job rotation, more than one person to lift a load, etc.

98
Q

Explain Individual with regards to manual handling assessment?

A

The individual
Aspects to consider: Risk factors inherent in the worker include physical, psychological and non-work- related activities that may present unique risk factors.
The individual’s ability to perform the task depends on characteristics such as age, gender, state of health, fitness. Vulnerable workers may be at higher risk and should also be considered.
Controls: The capabilities of the individual worker must be assessed in order to place the right person with the right task. It is also a good idea to send employees for regular health assessments, including fitness assessments. Special attention should be given to vulnerable groups and training adjusted to
accommodate them. Proper training should be provided to all individuals with proper supervision and information, as required in OHSA 8.

99
Q

Explain Load with regards to manual handling assessment?

A

The load
Aspects to consider: Aspects to include the weight of the load, the size of the load, the ability to grasp the load, the content of the load, the physical load – is it sharp, hot or cold?
Controls: Divide heavy / bigger loads to make it lighter, smaller or easier to grasp, provide handles, handholds or a sling to grasp the load, remove sharp edges or provide appropriate gloves for sharp or hot loads.

100
Q

Explain Individual with regards to manual handling assessment?

A

The working environment
Aspects to consider: The physical environment in which tasks are performed may introduce risk factors, such as space constraints, slippery or uneven floors, extreme temperatures, lack of ventilation or too much ventilation, poor lighting.
Controls: The working environment can be improved by cleaning floors and work areas regularly, damaged floor areas should be repaired, adequate lighting should be provided and temperatures and ventilation should be suitable to the working environment.

101

Q

Define Fatigue?

A

fatigue is a state of mental and/or physical exhaustion that reduces a person’s ability to perform work safely and effectively.

“Fatigue is more than feeling tired and drowsy. In a work context, fatigue is a state of mental and/or physical exhaustion that reduces a person’s ability to perform work safely and effectively. It can occur because of prolonged or intense mental or physical activity, sleep loss and/or disruption of the internal body clock.”

116

• Blurred vision or impaired visual perception
• Need for extended sleep during days off work
• Fidgeting
• Rubbing eyes
• Repeated yawning
• Staring blankly
• Excessive blinking
• Difficulty keeping eyes open

117
Q

Define Mental/cognitive fatigue?

Signs of mental/cognitive fatigue include:
• Negative mood
• Reduced ability to communicate effectively
• Slips and lapses in cognition
• Poor memory, especially short-term
• Inability to concentrate
• Reduced attention span
• Impaired problem-solving skills
• Increased risk-taking

118
Q

What are some of the causes of fatigue?

A

Fatigue can be caused by work-related or non-work-related factors, or a combination of both. These causes can include:
• Shift work, especially night work
• Inadequate time to recover between shifts
• Long hours of work or excess of hours due to overtime
• Long commuting times
• International or domestic travel across multiple time zones
• Excessive stress, whether work-related or private, e.g. family issues
• Mental health issues, including addictions that can cause or exacerbate fatigue
• Ill health, including medication that may cause or exacerbate fatigue

119
Q

What are the risk of fatigue?

A

The risks of fatigue are obvious – poor or impaired job performance, health risks to employees, near- misses (at best), incidents and, in the worst case, even major incidents can occur due to fatigue. The infographic that follows summarises five major human-caused disasters, all of which were the result in some way of fatigue:

FATIGUE AND MAJOR DISASTERS
Many major disasters have been caused entirely or significantly because of fatigue.

120
Q

What is a fatigue management plan?

A

Is a formal plan with policies and procedures that seeks to minimise the risk of harm from fatigue to employees in the workplace. Measures to minimise fatigue must be considered properly in open consultation with applicable managers, supervisors and employees

121
Q

Solutions that are considered as part of fatigue management could include?

A

• Detecting the first signs of fatigue is essential.
• Having a clear understanding of which employees/jobs may be prone to fatigue.
