Safety Precautions You Have to Keep in Mind When Using Sodium Hydroxide

There are several things to keep in mind when working with substances such as sodium hydroxide, a strong base with the chemical formula written as NaOH. This alkaline is famous in the industry for its pH-adjustment purposes, with its excellent ability to neutralize acids and acid oxides. The commonly known lye or pumice stone is used in the production of soaps and detergents and many cleaning liquids. It is also found in the processing of cotton, metals such as aluminum, textiles, paper and pulp. This ionic compound completely dissociates into sodium ions and hydroxide ions in aqueous solutions.

This substance has never been found to be flammable or combustible. But because it forms extremely exothermic solutions with water, for example, it is capable of releasing enough heat when mixed with water to burn nearby combustible materials. It also reacts with amphoteric transition metals such as aluminum, tin, and zinc. Typical reactions of sodium hydroxide with metals, as mentioned, release hydrogen gas, which ignites in the presence of oxygen.

Storage of this compound may involve tightly sealing its containers as it reacts with acidic oxides in the air. For example, it removes carbon dioxide from the air. Carbon dioxide is a natural acid anhydride and reacts with said base to form a salt called sodium carbonate.

Since this alkali has a lower heat capacity than water, it transfers heat easily. For example, mixing it with water causes a dangerous build-up of heat that can cause the mixture to spatter and spray sodium hydroxide everywhere. Pouring water on the solid form of this alkali can cause a violent reaction that sends an aerosol containing NaOH into the air. Bearing in mind that the substance is known to irritate the eyes, skin and respiratory tract, such activity is extremely dangerous. In addition, the extreme heat generated during mixing can be sufficient to destroy the container and cause spillage. So it is necessary to state the safe way to dilute the lye. A safer way is to introduce the substance slowly into the water. This avoids the release of enormous heat. As you pour the concentrated NaOH into the water, stir the mixture gently to allow a faster dissolution process and more rapid distribution of heat throughout the mixture. For this purpose, it is better to use cold water. Remember that this procedure is also done with concentrated acids. Special clothing and protective gloves must be worn when performing this procedure. Never pour water into a concentrated solution of this lye. Remember that even dilute NaOH solutions can still cause irritation and corrosion.

Alkaline is odorless, even in aqueous solutions. This means that you may not immediately notice exposure until irritation occurs. So you may already be dangerously exposed to alkali without realizing it. This should call for extra caution when working with the chemical.

The extreme corrosiveness and reactivity of this substance ensures that workers are highly likely to come into contact with this compound and to check the engineering controls of the work area. Safety equipment, protective equipment and clothing must always be available. The basic rule is compliance with hygiene requirements. Workers who are at constant risk of exposure to this chemical must be educated and informed about its properties and health hazards. In addition, they must be taught to handle the chemical carefully.

Work rooms must have proper ventilation. If there are any leaks or spills in the insulation, report it immediately. Check for leaks and damage before carrying and transporting containers.

There are several materials that must be kept away from this substance. Never place strong acids on a base, let alone mix them. NaOH should not come into contact with nitroaromatics, nitroparaffins, or halogenated compounds. As mentioned earlier, alkali reacts with metals such as aluminum, tin, and zinc. Therefore, it must not be transported in, for example, aluminum containers, as this may cause the release of flammable hydrogen gas and damage the aluminum container. In addition, it also reacts with glass. Therefore, glass containers are not suitable for long-term storage of the compound.
