Chemicals can either be useful or dangerous. This is why safety precautions are employed in all chemical laboratories and these stringent measures are only appropriate to avoid life-threatening mistakes. Generally, substances are harmless under the appropriate conditions. When we speak of appropriate conditions we are considering the proper storage, right temperature and pressure in the storage area, and the handling. While handling and storage of chemicals should be done with care, the observance of precautions when mixing different substances is even more compelling.Watch all the household chemicals, for instance, and you will understand that all these items come in solutions and mixtures of two or more ingredients. Mixtures and solutions are also quite important in many industrial sectors from agricultural chemical processing to chemical reagent preparations. In many processes calling for chemical mixing, mixing chemicals should be done in the most controlled procedures, often requiring sophisticated instruments and safety gears or protective suits.There are many chemicals that are extremely hazardous. Mixing two or more substances can result to one of several types of reactions, all of which have one common feature and this is the production of new substances or new mixtures. Many useful chemicals have been manufactured through mixing of different chemicals. Various effects can happen when mixing substances though. These include precipitation of a new substance, evolution of heat, absorption of heat, and evolution of gas (if one of the products is a gaseous substance).Of course, change in the color of the mixture is an apparent indication of a reaction happening. The matter with combination of two or more substances is that toxic chemicals or gases may be the products of the formerly inert substances. In other cases, some chemicals could react vigorously with the production of enormous heat, which in uncontrolled instances can set nearby objects on fire. One of the most hazardous effects of crude mixing of certain substances is that a rapid evolution of toxic fumes may result. Doing such procedure without proper gears and instruments could expose one to hazardous substance.Companies that do substance mixing or chemical filling should ensure that the stringent procedures are followed to avoid fatal accidents from happening. A single mistake can risk the life of many. The education of workers is imperative. Everyone working in the area should understand the sheer danger of chemicals and the products upon mixing. The following of standard procedure is a basic necessity in any chemical labs. Safety apparatuses should be at hand. Protective suits must be worn if necessary and if chemicals that are to be handled are corrosive and toxic. Ventilation is a basic thing.It is also imperative that industrial workers who are often exposed to certain chemicals know which chemicals to watch out for. Some of them may not exactly understand what the exposure could mean. Furthermore, some do not understand the basics in mixing certain substances safely. Of course, there is no need to remind the chemists and the chemical engineers, but they, too, should realize the repercussions of complacency.As a general rule, anybody should not attempt to mix two or more unknown chemicals. Also avoid mixing household chemicals if you are unsure about the resulting products. There are certain chemicals at home that could generate dangerous gases when combined. For instance, bleach and ammonia may produce toxic chlorine and other irritating fumes that could render you unconscious. Even mixing some compounds with water should be done with precaution. For instance, mixing water and strong acids and alkaline can produce enormous quantities of heat.If you are purchasing chemicals, always ask the dealer about the properties of the substances. Also inquire about the proper handling and storage as well as the possible hazards. This information may not come with the chemical packaging, chemical packing, or chemical specifications.
Workers in chemical labs and industrial plants are more exposed to dangerous substances than any other professionals. Dealing with several substances everyday can expose these people to the known hazards. There are different, hundreds of types of chemicals and many products we use everyday were first raw chemicals coming from laboratories. Soap and detergent, for instance, are a mixture of fat and a strong alkaline like sodium hydroxide, one of the chemicals sold at many chemical manufacturing plants. Manufacturers create and sell different formulations, reagents and solutions through chemical mixing by mixing chemicals in the standard way to achieve the desired and accurate results.The danger of the job to which workers are exposed comes from the very nature of many chemicals found in the area. Strong acids and bases, explosive chemicals, volatile liquids that emit irritating vapors and toxic gases are some of the hazardous chemicals. Reckless handling of chemicals can result to injury. Strong acids and alkaline can cause serious burns. Exposure can also lead to blindness and swelling of the air passages. Toxic gases can cause death upon prolonged exposure. Nonetheless, it is not only the injurious nature of many chemicals that pose danger to people. Many of them can cause damage to property through corrosion and contamination. The rehabilitation of damaged property could be costly and cumbersome.Another major concern that arises is the disposal measures employed by chemical and industrial establishments. Chemical filling and manufacturing companies are regulated by certain agencies to ensure they abide by the regulations encompassing proper disposal of their waste and sludge that harm the environment if not managed appropriately.The risks are always present. However, they can be mitigated by properly educating workers about different chemicals, about reactivity, about toxicity, and about contamination and exposure. Mishandling of many substances can pose various hazards at the working station and even the most trained personnel can be endangered by negligence and lack of tact. For instance, chemical leftovers should be left lying in unsafe places. They should be disposed of using the prescribed procedure and in the right location. Some strong chemicals are neutralized before disposal. Toxic chemicals should be kept in sealed containers. Hazardous substances may not be thrown away indiscreetly. They should be placed in discrete bottles and labeled.In any chemical manufacturing process, the importance of accurate measurements and standardized and calibrated equipment and instruments is basic. Production of chemicals involves stringent measurement procedures to make certain that the right amount and the right quality of products are obtained. Moreover, many companies relying on such chemical manufacturing industries expect that the substances are unadulterated. A certain substance may be required in varying amounts and concentrations. For example, hydrochloric acid may be produced in varying molarities or normalities and concentrations depending upon the basic application of the purchasing company or client.The workplace itself should be so structured as to lessen the effects of spontaneous accidents. Safety equipment such as gas masks, gas monitoring device, fire fighting equipment, and emergency phones must be installed in the area. Emergency exits are imperative.In addition, the equipment used for the chemical processing must be well inspected from time to time to ensure they function appropriately. Machine glitches and damaged instruments can produce poor quality products and put the risk of workers at the same time.The products should also be well assessed and tested to ensure that the resultant product is of excellent, standard quality. During chemical packaging, chemical packing should include label, directions, and precautions to give users general information about the product and how to and how not to use it. The most effective way to avoid accidents is to inform people about the chemical product, what it contains, and how to avoid the hazards that come with it.
