Cleaning and the Environment by k.charvi
In this age of environmental concern individuals are outwardly interested in the healthy state of their surroundings. As populations increase and we become more connected with our environment and each other through global communication, commerce and transportation, that interest also increases. Our desire for a clean environment represents a powerful sense of destiny and hope for the future.
The Many Benefits of Our Environment
The environment provides many benefits. It heals us and helps us stay healthy. While medicines are derived from the elements of the environment and living organisms, sometimes simply being exposed to sunlight and fresh, clean air makes a difference in how we feel.
Our surroundings educate. Science and technology are the products of observing, studying and using the physical, chemical and biological world around us.
Why Clean?
Clean is a condition of the environment that is free of unwanted matter. Cleaning is the process used to achieve the clean condition. Best viewed as a fundamental environmental management process, cleaning is a systematic, science-based process that puts unwanted matter in its proper place or where it does not cause harm or adverse effects. Understanding the importance and effectiveness of cleaning allows us to fully appreciate its usefulness and the contributions it makes to the quality of life.[8]
Cleaning Reduces Environmental Risks, Enables Sanitation
Sanitary conditions are where the risk of adverse health effects is low or acceptable.[11] Effective cleaning reduces exposures to hazardous matter, thereby reducing risks while contributing to a sanitary state.
Indoor environments are readily manageable, unlike ambient environments where the causes of pollution and its control are complex. Built environments can be designed, operated and maintained to suit their inhabitants’ needs.
We need to better understand the influence natural and manmade environments have on our health. Once we do, it becomes apparent that effective management, especially in the form of cleaning, is the key to removing unwanted by-products and reducing serious health risks.
The question then becomes how clean is clean?
In the tradition of environmental health clean is perceived on three levels: sterilization, disinfection and sanitation. For an environment to be considered sterile it must be 100 percent contamination-free. Sterilization can be achieved, although it is extremely difficult since in routine cleaning items and places—as a rule—are not sterilized.
An environment is considered disinfected if the vast majority (99 percent) of its harmful substances are removed or made safe. The pathogens most threatening to humans also must be eliminated. A disinfected condition only can be achieved with considerable work and energy.
Sanitary environments are cleaned to the extent that general health is protected. Some contamination, however, is present and an acceptable risk level for disease exists. At a minimum, cleaning always must attain a state of “sanitation,” since unsanitary conditions pose a likely health risk. Cleaning is designed to rectify any risky conditions. Environments must be cleaned regularly to keep them sanitary. If the health risk has not improved to a sanitary level, cleaning has not been accomplished.
Effective cleaning removes unwanted matter to the greatest or optimum extent possible. Doing so ensures acceptable risk—the reduced probability of an adverse effect for humans, their valuables and the natural environment—from exposure to such matter. By virtue of this definition and its thoughtful design, effective cleaning fully protects the environment.
