Potential Hazard Bright lights shining on the display screen "wash out" images, making it difficult to clearly see your work. Straining to view objects on the screen can lead to eye fatigue.
Most workers are exposed to excessive heat at one time or another. In many situations, artificially hot climates are created by the demands of the particular industry. Miners are subjected to hot working conditions due to the increase of temperature with depth, as well as a lack of ventilation.
Textile workers are subjected to the hot, humid conditions needed for weaving cloth. Steel, coke, and aluminum workers are subject to intense radiative loads from open hearth furnaces and refractory ovens. Such conditions, while present for only a limited part of the day, may exceed the climatic stress found in the most extreme, naturally occurring climates.
The human is typically modeled as a cylinder with a shell, corresponding to the skin, surface tissues, and limbs, and with a core, corresponding to the deeper tissues of the trunk and head.
Core temperatures exhibit a narrow range around a normal value of 98.6° F (37 C). At values between 100-102° F (37.8-38.9° C), physiological performance drops sharply. At temperatures above 105° F (40.6° C), the sweating mechanism may fail, resulting in a rapid rise in core temperature and eventual death.
Vibration can cause detrimental effects on human performance. Vibrations of high amplitude and low frequency have especially undesirable effects on body organs and tissue.
The parameters ofvibration are frequency, amplitude, velocity, acceleration, and jerk. For sinusoidal vibrations, amplitude and its derivations with respect to time are:
The concept of job satisfaction
has been typically defined as an
individual’s attitude about work
roles and the relationship to
worker motivation (Vroom, 1967).
