How to Store Chemicals Properly
Chemicals should be stored properly and it is important to know how to do it especially if you have a lab or a research center. The occupations safety and health administrations or OSHA has given out the requirements for storage that should be considered. Here are the chemical storage requirements that we should comply with.
Simply putting chemicals on shelves is not enough. Chemicals of different kinds should be separated and stored according to their kind. There should be different storage places or cabinets for different kinds of chemicals.
When chemicals are mixed there is a reaction so you need to take note of this when you are storing your chemicals. If there is negative interaction between two types of chemicals, they should be kept far away from each other. Solvents and oxidizing agents should not be put together, and solvents should be kept in cabinets that are fire resistant. Do not put acids (nitric, hydrochloric, and sulfuric) and bases (sodium hydroxide, potassium hydroxide, slaked lime, sodium carbonate, and aqueous ammonia) together in one cabinet. When corrosive bases and joined with acids there is a risk that the mixture will generate heat. Labels should be put on chemical containers and labels should be put on cylinder shoulders.
There should be at least five chemical storage cabinets as recommended by the OSHA. There should be one for general storage where you can put the chemicals depending on their categories or hazardous rating, the acid area where only acids are stored, an area for corrosive acids, one for corrosive bases, and another one for flammable chemicals. These cabinets should be far from sinks or water sources and should always be locked. When liquids are kept in safety cabinets, excessive chemical vapors may be a concern. It is best to put these cabinets away from the sunlight but in cool, dry places. Hazardous signs should be put up on cabinets or storage places for chemicals.
OSHA does not have a specific color coding system, but they recommend that you create a system that will help to identify specific chemicals. For example, you can use red for flammable chemicals, yellow for reactive or oxidizing agents, chemicals hazardous to health can be colored blue, corrosives chemicals can be white, and green and gray for those chemicals that are only moderately hazardous.
Safety storage procedures should be taught to those who handle the chemicals regularly. OSHA recommends that training should be completed every few moths. New chemicals brought to the facility should be known to all and should be handled and stored properly. Chemical storage is very important. The protection of property and personnel are ensured when chemicals are stored properly. You should ensure that all chemicals are handled by trained and qualified personnel.
