Play chemicals major role in the life of individuals and peoples to become the welfare and progress of peoples measured including findings of the discovery and use of chemicals in various areas of life, and the use of chemicals double-edged sword, if the best use of the express facial bright and useful for mankind 00 If abused the use of these substances they reveal the ugly face that causes the destruction of human and wasted the lives of individuals and there is a chemical in the work environment in one of the following images: -
- That the chemicals take more than one form is present in the image of (liquid - gas - solid) 0 - the ability drying food preservation of force to the human body quick and through (respiratory, digestive and skin contact) 0 - that the impact on the members of the body is their interaction with some members of the body and therefore affect drying food preservation it adversely, such as lung fibrosis and septicemia 0 - to the degree of influence of acute resulting from this article flesh may occur immediately after entering the body or occur after a period of time 0 - that some of these materials have no taste or color or smell and therefore difficult to humans sensation or speed detection 0 - that the rapid spread of these materials from their locations broadens the base effect and caused damage 0 - that the presence of these substances the body leads to unbalance and affect drying food preservation the efficiency of some members of the body 0 - may have an impact on some of the equipment work like rust or corrosion and self explosion and fire 0
Safety and health Almhennehaloajp availability to protect workers from the risks of chemicals 1 - must be provided precautions to protect workers exposed to the risk of exposure to chemicals drying food preservation used, whether the material in gaseous, liquid or solid and make it within the limits as described in the table attached 0
2 - medical examination must be performed on the primary drying food preservation workers when they enter the work exposes them to the risks of chemicals to detect any medical condition or latent drying food preservation phenomenon strongly affect the workers when they are contaminated with chemical and keeps score factor file medical examination to compare the results of the following tests 0
4 - You must provide effective technical means for the prevention of harmful chemicals such as: - replacement of industrial processes drying food preservation that use substances harmful to health somehow harmless or less harmful. - The removal of industrial processes harmful to health in the places of their own to reduce the number of exposed workers with the management of the means of prevention for this small number of workers 0 - use machinery closed completely, which is not caused by use of any impurities do not need to contact employees to place the damage whenever possible 0 - choose machines that managed drying food preservation mechanically and do not require the direct supervision of workers to manage them so that they can run with the survival factor within safe so as not exposed to inhalation of gases or vapors or dust, harmful or splash liquids mounting drying food preservation of machinery 0 - use methods of sedimentation or moisturizing to get rid of dust or fumes harmful 0 - Use ventilation whether ventilation public or ventilated spot next to the place rising gases and vapors or fumes or dust harmful collected and disposed of before it reaches the ocean breathe workers 0 - use synagogues vacuum drying food preservation or after moisturizing drying food preservation to remove dust or impurities from places deposition so as not to escalate to the air again and inhale If you use workers through the regular synagogues 0 5 - must make the necessary periodic measurements of chemical risks in the work environment depending on the type of activity Sundials and recorded and compared periodically to make sure they are within the permissible limits 0
7 - You must provide sufficient water for washing or bathing for workers after school and before they left the workplace to remove suspended body of pollutants harmful chemicals while providing cleaning equipment (such as soap, towels, etc.) and must be secured ed gauze to emergencies in the workplace so that it is easily accessible 0
12 - When any flammable materials spill on your clothes or any part of your body it is obligatory for you to use a stream of water on the position of the injury with the speed of disposal drying food preservation of contaminated clothing and not to approach the places open flame so as to prevent injury and doubled reduce the severity 0
26 - you must know the physical drying food preservation and chemical properties of the materials used in laboratory experiments as well as knowledge of the properties of materials resulting from the interactions drying food preservation and the light are selected tasks of personal protective goggles, masks and gloves 0
36 - When storing chlorite sodium should drying food preservation be stored in a dry place and at normal temperature (in the range of 15 C) 0 and must not be touching material any acids or flammable materials such as wood, straw, textiles, fatty substances, oils because drying food preservation they oxidizing substance strong 0
41 - are stored persulfate ammonium away from the material shorthand or mineral acids or flammable materials 0 and must be taken not to expose it to material booster biodegradable such as iron, copper, lead, 00 etc. and should not be touching article or محاليلها of the skin or eye, where they cause burns, chemical and thermal severe and shall wear protective equipment such as glasses - Jawanty - and if the body is exposed
