The effects of environmental factors in the laboratory

The measurement results do not mean a single concept and they should be standardized and compared. After measuring and comparing with standards necessary measures to control and prevent environmental hazards in the work and impact of these factors on the results will be made. Therefore, the identification of environmental factors in the laboratory is of particular importance. Generally environmental factors in the laboratory are as follows: Physical factors: noise, vibration, lighting, heat, humidity, cold, pressure, radiation. Chemical elements: Chemical materials: solid, liquid, gas and steam, suspended particulate matter (dust, smoke, fog, etc.) Biological factors (biological): viruses, bacteria, parasites, fungi and so on. Ergonomic factors (poor ergonomic conditions): improper body posture while working, physical mismatch between the worker and the work assigned, appropriate tools and so on. Mechanical factors: Any factor in the workplace which caused the accident or injury such as a work tool, sharp edges or works at height. If optimal, recommended conditions and standards for the elimination of harmful factors are not respected in workplace will lead to damaging factors and will certainly affect the accuracy of the results, so the identification and elimination of harmful factors are of importance.
