Ch 1 Flashcards
Legionnaires disease
Type of pneumonia caused by bacterium.
Bacterium contaminates hot water tanks, hot tubs, and cooling towers of large air conditioners.
Farm workers are least likely to get them.
Office workers are most likely to get them.
SARS disease
Caused by corona virus
Lyme disease
Forestry workers are most likely to get this. Caused by 8 legged ticks
Anthrax & Tularemia disease
Bacterial diseases found in people working with animal hides
Histoplasmosis disease
Farmers might get it which is caused by fungus that grows on old manure, droppings. Releases spores.
Psittacosis disease
pet shop owners might get this disease
Mycotixin
Poison produced by molds
2 traditional sources of mold causing occupational illnesses
- pigeon and bat excrement
2. machine cutting fluids
Farmers lungs
is associated with Aspergillus versicolor molds (fungus). lung infection in hospital patients too.
Stachybotrus chartrum
Health problems from molds (fungus) in buildings.
Rocky mountain spotted fever
Its a tick borne disease. Forestry workers are most likely to get this.
Tuberculosis (TB)
A disease caused by bacteria called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but they can also damage other parts of the body.
Definition of Occupational Hygiene - AREC
The science and art devoted to the anticipation, recognition, evaluation and control (AREC) of those environmental factors and stresors arising in or from the workplace, which causes sickness, impaired wealth and health being, or significant discomfort, among workersor citizens of the community.
Heat Stress Outside (with sun)
WBGT =
WBGTout = 0.7 Tnwb + 0.2 Tg + 0.1Tdb
Where: Tnwb is the natural wet bulb temperature. The natural wet bulb temperature is a measurement of temperature that takes into account the impact of both humidity and air movement.
Tg is the globe temperature. The globe temperature is a measurement of radiant heat from surrounding processes and equipment and convective heat exchange with the ambient air.
Tdb is the direct measure of the air temperature
Heat Stress Indoor
WBGT =
WBGTin = 0.7 Tnwb + 0.3 Tg
Where: Tnwb is the natural wet bulb temperature. The natural wet bulb temperature is a measurement of temperature that takes into account the impact of both humidity and air movement.
Tg is the globe temperature. The globe temperature is a measurement of radiant heat from surrounding processes and equipment and convective heat exchange with the ambient air.
