Class of household and chemical waste

Since primitive times man left behind a lot of different waste. In the process of the development of civilization they became more and more dangerous both for man and for nature. Now all the wastes of our life activity are classified according to the degree of danger into types and classes.

Hazard Class of Waste Depending on their type. Waste is household or chemical. Household, or solid household waste, are also divided into safe and dangerous. Safe paper is considered paper or cardboard, wood, metals, textiles, rubber, glass and plastics, as well as food waste. Dangerous solid waste includes broken equipment and medical devices containing acid or mercury, as well as overdue drugs and fertilizers. It is these wastes that have a hazard class.

Dangerous solid waste is divided into five categories or classes. The most harmless belong to the first class. The fifth class includes wastes, the most polluting water and air. The list of such wastes includes mercury from broken thermometers and burned energy-saving light bulbs, the remains of paint and varnish from Delium, acid from broken batteries or accumulators and unsuitable medications. Outlived tires and other wastes are distributed to other classes. Hazard Class No. 5 means that special substances are used for the substances included in it.

Dumps are the main danger associated with solid waste. Even relatively safe waste piled into the pile harms the environment. The only way to save nature from wastes that have any hazard class is to properly dispose of them. Ideally, all household waste should be disposed of in separate containers and processed as recyclable materials. Another method of utilization - burning - is very harmful, because the carbon dioxide and dioxin contained in the smoke poison the atmosphere and corrode the ozone layer.

Chemicals are also divided into classes. The hazard class of chemicals depends on the size of the lesion, and, of course, on the damage that these substances cause to nature. Traditionally, chemical substances have a four-class division, in which the most dangerous chemistry belongs to the first class. However, there are other classification systems. Thus, in the year 1967, ZD Zagonnikov M developed a system that classifies poisons. The chemicals in it are distributed according to the concentration and magnitude of the lethal dose. There is also a system that separates poisons according to industrial application for agricultural, medical, domestic, biological and military. Separate toxic chemistry and the effects on the body. According to this system, there are poisons of the nervous, hepatic, renal, blood, gastrointestinal and pulmonary. Military doctors divide toxic substances by tactical influence.

Despite the type and class of danger, any waste is harmful to nature, thus undermining our health. Humanity is in danger of completely ruining the ecology of the planet if it does not learn to dispose of hazardous substances on time and correctly.
