Any inherent technological stages, and in particular food, the production – disinfection and cleaning. These two processes are closely related. Disinfectants used for disinfection of various surfaces and Prevention of infection by microbes food. Detergents are used to remove impurities of chemical origin. With the right as washing removes virtually 100% of dirt and bacteria. Follow disinfection bring that percentage up to 100%. Effective disinfectants must have low toxicity, broad spectrum antimicrobial activity, ease of use, versatility and long-term storage of concentrates and working solutions. There are some basic rules and criteria for the selection of disinfectants: 1.
Disinfectant must be corrosive (or slightly) low toxicity. Current disinfectant must not cause corrosion of metals and other damaging materials that are part of the equipment to maintain activity in the presence of organic substances, not to toxic and allergic effects. 2. Disinfectants should be of high quality, diverse and focused. The main objective for disinfectants – creating an effective, reliable protection from infections.
3. Disinfectant should be feasible. In the current economic conditions, reductions in the costs of industrial plants, food manufacturing, meat and dairy products, beverages itp, ceases sharply the question of cost and quality of disinfectants used to clean equipment. Typically, the best solution and the solution is to use multi-purpose cleaning and disinfectants. It is therefore necessary to choose fast, reliable and effective against yeast, bacteria, viruses, fungi, and spores. Detergent properties of disinfectants are to remove liquid and solid contaminants from the surface and transfer them to the washing liquid in the form of solutions. Detergent action is manifested in the complex processes of interaction of pollution, cleaning mediums and surfaces. The main phenomena determining detergent action, are the processes of physical and chemical adsorption, wetting, emulsification, foaming and stabilization. To obtain the desired effect of disinfection must be followed carefully prepare and use of disinfectants.
The color has fascinated culture throughout history, every age and every region has produced dyes and pigment depending on available resources. The color has been with us for more than 20,000 years. The evidence survives in cave paintings. The color was widely used by the ancient Egyptians and was considered to have magical and healing, and around this time, 1500 B.C., features painting that made while an art was established quite widely in Crete and Greece with the Egyptians who passed his skills to the Romans. Egypt: The Egyptians used a technique of Temple, bringing together the pigments with water and rubber, glue and egg and applying colors separately, without mixing them among if.
Is not there a number of life-saving? They can be anything that will increase the buoyancy of a person and that you are able to it in good faith (Life preserver, a boat, floating logs, etc.). Cheerfully screaming victim, you are going to help. If you got to swim a drowning, it is necessary to take into account the maximum flow of water, wind, distance to shore etc. Approaching, Try to reassure and encourage forces of vybivshego swimmer. If it failed, and he can control his actions, the swimmer must keep the shoulder saver. If not – deal with it must be hard and ruthlessly to save him and save his life. Brief safety looks like this: swam to the drowning man, you must podnyrnut under him, and took back one of the methods of capture (classic – the hair), transported to shore.
