STC SA 3 Flashcards
What is Occupational hygiene?
The science and art devoted to the anticipation, recognition, measurement, evaluation and control of those environmental factors or stressors arising from the place of work which may cause illness, disease, impaired health and wellbeing or significant discomfort and inefficiency among workers or among members of the community
Define the difference between a Hazard vs. risk?
HAZARD means a source of or exposure to danger. It is anything that can cause harm.
RISK is the probability or likelihood that injury or damage will occur.
Define the difference between Sampling vs. monitoring?
SAMPLING is a process consisting of the withdrawal or isolation of a fractional part of a whole. The taking of a sample is to estimate the extent or magnitude of the environmental stressors.
MONITORING means a continuing programme of observation, measurement and judgment of an environmental stressor. Monitoring include planning, carrying out sampling and recording of results to enable a judgment to be made regarding the adequacy of the control measures employed to safeguard the employee and the members of the community.
What are the Occupational exposure limits?
- Time Weighted Average Exposure Limit (TWAEL)
- Short Term Exposure Limit (STEL)
- Ceiling Exposure Values (CEV)
Explain TIME WEIGHTED AVERAGE (TWAEL)?
The limit to which an average employee can be exposed for a normal shift of 8 hours per day, 5 days a week without suffering any ill effects.
Explain SHORT TERM EXPOSURE LIMIT (STEL)?
Can be defined as a 15-minute TWA exposure which should not be exceeded at any time during a workday even if the 8 hours TWA is within the OEL-TWA. There should be at least 60 minutes between successive exposures in this range.
Explain CEILING EXPOSURE VALUES (CEV)?
Concentrations of the biological or chemical agent in the workplace air that must never be exceeded.
What does ALARA stand for?
As Low As Reasonably Achievable.
This term expresses the principle that the exposure to any hazardous material should not only be lower than the stated exposure limit but as low as it reasonably can be.
What is the Sk” notation?
This means that absorption through the skin is a significant route of entry for that substance.
What does the SEN notation stand for?
Sensitisers are those substances that can produce allergic reactions.
Occupational health= occupational hygiene + occ medicine + primary health care
What is meant by “stressors’ and what are the types?
The environmental factors, stressors or risks that may cause sickness, impaired health, discomfort or inefficiency in workers may be classified as chemical, physical, biological, ergonomic and psychological.
Give examples of Chemical Stressors?
Dust, Smoke, Fumes, Mist, Gases and Vapours.
DUSTS: Solid particles generated by handling or crushing of organic or inorganic materials.
SMOKE: A suspension of particles that often originates from combustion. Carbon or soot particles result from the incomplete combustion of carbonaceous material.
FUMES: Solid particles generated by the condensation of a gas, generally after volatilisation from a molten metal.
MISTS: Suspended liquid droplets generated during the condensation from the gaseous to the liquid state. It can also be formed when liquids are broken up into the dispersed state such as by splashing, foaming or atomising. Mists are formed when a finely divided liquid is suspended into the air.
GASES: Gases are formless fluids which occupy space and can be liquefied or solidified by the combined increase in pressure and decrease in temperature to below the critical temperature.
VAPOURS: The gaseous form of substances which are normally in the liquid or solid state at normal room temperature and pressure.
Give examples of Physical Stressors?
Physical stressors includes: Illumination, noise, vibration, thermal conditions, radiation, ventilation and indoor air quality.
Give examples of Ergonomic Stressors?
- Includes improperly designed tools or work areas.
- Improper lifting or reaching, poor visual conditions, or repeated motions in an awkward position may be responsible for accidents and inefficiency of workers in the occupational environment.
- Designing the tools and the job to be done to fit the person should be of prime importance.
Give examples of Biological agent Stressors?
A biological agent means any microorganism, cell culture or human endoparasite, including any which might be genetically modified, which may cause infection, allergy or toxicity, or otherwise create a hazard to human health. Typical stressors that can be encountered in the workplace include insects, rodents, viruses, bacteria and parasites.
Give examples of Psychological Stressors?
Include occupations which might endanger mental health. Examples of psychological health effects that can develop are neurosis, a condition caused by overloading the senses. This might lead to absenteeism, tiredness, sleeplessness, heart disorders, peptic ulcers and even asthma.

Define Contrast?
Contrast is the relationship between the brightness of an object and its background.
Define Glare?
Glare is a visual condition where there is discomfort and/or a diminished ability to distinguish identifiable objects due to unsuitable illuminance diffusion or luminance limits, or as a result of extreme contrasts, simultaneous or successive, within the field
of vision. Any brightness within the field of vision with such characteristics would cause discomfort, annoyance, interference with vision or eye fatigue.

OHS Act 85 of 1993, Environmental regulations, section 3 Lighting and lighting schedule SANS 10114
Define Sound?
Is defined as any pressure variation (in air, water or some other medium) that the human ear can detect. Sound can also be defined as a stimulus that produces a sensory (auditory) response in the human brain.
Define Noise?
Is defined as usually sound that bears no information and whose intensity varies randomly in time. Noise is normally regarded as an unpleasant and unwanted sound.
What is considered to be a Noise zone?
An Area where the noise level is or exceeds 85dB (A) (SA) and 90dB(A) (USA).
What is a temporary threshold shift?
in hearing occurs immediately after exposure to significant loud noise. Quiet sounds can no longer be heard and the condition may last for minutes to hours.
What are the three main groups that noise can be classified in?
- Continuous Noise
- Interrupted Noise
- Impulse Noise
CONTINUOUS NOISE
Continuous noise occurs for example when an electric motor is switched on. This is a monotonous continuous sound with little variance in the frequency and intensity.
INTERRUPTED NOISE
Interrupted noise occurs when there are variations in sound levels due to the on-and-off switching of the machine during a production cycle. The nature of the sound is the same but it is alternated by periods of silence.
IMPULSE NOISE
Impulse noise has a unique feature in that it consists of a very intense sound lasting only a short period, e.g. a gunshot, hammer blows.
The NRR (attenuation) is conducted under controlled laboratory conditions and does not take into account?
A-weighting scale

How does Whole Body Vibration (WBV) Occur?
Occurs when a human body is supported on a surface which is vibrating and causes the body to vibrate.
What are some common sources of WBV?
Large numbers of workers are exposed to WBV with delivery vehicles, forklift trucks, lorries, tractors, buses and loaders as the most frequently reported sources of WBV. Vibration can be due to the machinery itself or the road surface.
Define HAVS?
Hand-arm vibration syndrome
What are the effects of HAVS?
- Prolonged exposure to vibration through the use of hand-held power tools and equipment leads to damage in several organ systems of the upper limb.
- Damage to the vascular system is a direct effect of the vibration on the blood vessels themselves. Such damage can cause impairment to the circulation.
- Neurological and muscular damage causes numbness and tingling in the fingers and hands. Neurological damage also causes a reduction in sensation to touch and temperature, as well as reducing grip strength and manual dexterity.
- The symptoms experienced from bone and joint damage are pain and stiffness in the hand, joints of the wrist, elbow and shoulder.
- Osteoarthritis and bone cysts occur in workers who are exposed to vibration from hand-held tools.
OHS Act, environmental regulations section 2. thermal requirements state that?
TWA WBGT measured over 1 hour must not exceed 30.
Define Ventilation?
Ventilation is actually a combination of processes which results in the supply and removal of air from inside a building.
What are the two types of Ventilation Systems?
General Ventilation.
Local exhaust ventilation.
General ventilation 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.
Local exhaust ventilation 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.
What is Radiation?
Radiation is the emission or transmission of energy as waves or moving particles.
Define Occupational health?
The promotion and maintenance of the highest degree of physical, mental and social wellbeing of workers, prevention of disease, practised in a balanced synthesis of several disciplines including occupational hygiene, occupational medicine and biological monitoring.

principle) by placing them in jobs to which they are suited (inherent job requirement).
- Contributing towards workers’ physical and mental adjustment, social well being (health promotion principle) as well as their ability to conduct a socially and economic productive life.
- Minimising the consequences of occupational hazards, accidents and injuries and
occupation-related diseases (the cure and rehabilitative principle).
- Providing general healthcare services for employees and their families, both curative and preventive (the PHC principle) either on-site, or by providing means like health cover assistance, e.g. medical aid/social security.
The guiding principle should be to ensure as far as is reasonably practical:
- A safe and healthy workplace.

Define a Risk?
Risk is the chance or likelihood of a hazard causing harm or damage to a person or to property or the environment.
The extent of the risk depends not only on the severity of potential harm to a person, property or the environment but also on other factors such as the number of people exposed.
The OHSA defines risk as to the probability that injury or damage will occur and the MHSA defines it as the likelihood that occupational injury or harm to persons will occur.
Define Pure Risk?
Pure risks are associated with hazards in ‘spheres such as health, safety, environment and security where success with risk control can be the removal of the hazard so that exposure is zero and no harm can result, i.e. no accidents, zero
product defects, no crimes. (Waring and Glendon, 1998, p4).
