Whether it be lab tables or lab benches, most laboratories use dangerous chemicals. While the types and amounts of chemicals used can vary greatly depending on the lab’s focus, accidents and mishaps related to the use and storage of hazardous chemicals are unfortunately all too common.

Below, we’ll go over some general safety guidelines, storage methods, and storage principles for the handling and storing of dangerous chemicals in any laboratory setting. Continue reading below to learn more about how to remain cautious when handling and storing chemicals and hazardous materials and find out how LabTech Supply Company, Inc. can provide your laboratory with adequate storage equipment.

Guidelines for Safe Chemical Storage

Chemical storage that is organized properly also aids in making better use of limited laboratory space. For proper and safe storage, chemicals should follow the guidelines below. By following these storage guidelines, laboratories can ensure safer chemical storage while also improving lab housekeeping and organization.

Proper Placement

First and foremost, labeling is required on all chemical containers.

When not in use, keep all chemical containers closed. Every chemical should have a distinct chemical storage location, which should be returned after use.

To avoid clutter and spills, and to allow for adequate working space, keep chemical storage on benchtops to a bare minimum.

The storage of chemicals in fume hoods should be kept to a bare minimum and only for the duration of the experiment.

Larger chemical bottles should be kept in the back of the chemical storage, while smaller bottles should be kept in the front, where they can be seen.

Chemical Safety

Multiples of the same chemical should be stored together, older containers should be placed ahead of newer chemicals, and containers containing the least amount of chemical should be placed last.

To reduce bottle breakage and leaks, flammable liquid chemical containers should be placed in secondary containment, such as trays. Furthermore, chemicals should always be separated and stored according to their compatibility and hazard classes.

Acids should never be kept near flammable materials or flammable gases or in a chemical storage cabinet or storage area. To that end, corrosive acids that can harm the eyes or other hazardous chemicals should be stored below eye level.

Flammable liquids should not be kept in standard (non-explosion-proof) refrigerators or freezers. Other chemicals that are highly toxic or flammable, such as inorganic cyanides or other organic acids, should be kept in locked storage cabinets or storage areas.

Always have spill kits and other spill control equipment on hand in all storage areas.

Examples of Incompatible Chemicals

Some chemicals should never be mixed. In fact, these chemicals should not even be stored near each other for fear of a chemical reaction in the event of an accident. Here are some examples of dangerous combinations to avoid:

  • Glacial acetic acid with chromic acid
  • Hydrogen peroxide
  • Metal powders
  • Bromine
  • Ammonium salts
  • Acids and cyanides
  • Oxalic acid
  • Fluorine
  • Copper
  • Ammonia
  • Mercury

Basic Chemical Segregation

Maintaining chemical segregation requires good housekeeping. To avoid contamination from a substance being placed in the wrong container, all chemicals should be properly labeled. Similarly, ensuring that all secondary containers are thoroughly cleaned after each use will prevent cross-contamination. Nothing should ever be stored under the fume hood when it is not in use, and all workbenches should be free of chemical compounds.

When keeping chemicals separate, keep in mind that not all of them follow the compatibility matrix’s rules. For a chemical compound that falls into two or more groups, it’s a good idea to seek professional advice on how to set up chemical storage areas.

When two incompatible chemicals come into contact with each other, they produce a reaction. In turn, a reaction in an uncontrolled environment can cause serious harm or even death.

How to Properly Store Chemicals

Chemical mixtures that react violently to produce heat, pressure, fire, explosion or another type of violent reaction are considered incompatible materials and should be stored with caution to avoid uncontrolled mixing.

Segregated storage is required for a variety of chemical classes, including:

  • Acids
  • Bases
  • Highly-flammable liquids
  • Highly-flammable gases
  • Combustible materials
  • Chlorinated solvents
  • Noxious chemicals
  • Toxic poisons and other mixtures
  • Oxidizing reagents
  • Highly reactive compounds
  • Regulated chemicals
  • Radioactive materials
  • Carbon dioxide

When it comes to designing your lab’s chemical storage areas, chemical compatibility should be a top priority. While it’s usually sufficient to divide chemicals into generic hazard groups, be cautious and double-check anything you’re not sure about to avoid flammable liquids and other flammable materials that may be stored together in your storage cabinet.

Because a hazardous chemical is incompatible or unsuitable for mixing, violent reactions can occur when they are stored or mixed together. During storage, incompatible materials should be separated into groups based on their hazard class.

Suggested Storage Time Limits for Common Peroxidizable Compounds

Peroxidizable compounds can build up in the chemical container under normal storage conditions and explode when exposed to heat, friction, or mechanical shock. When a peroxide-forming chemical is concentrated through distillation or evaporation, the risk increases.

Peroxides have a tendency to explode violently, posing a serious risk of serious injury or death to laboratory workers. It is critical that all researchers learn to recognize peroxidizable chemicals and handle them safely.

Any peroxide-forming chemicals must have a Standard Operating Procedure (SOP) or safety data sheet that has been reviewed and approved by an environmental health and safety official. If you are unsure about this process, please contact a local health and safety official for assistance in developing a specific SOP before using it.

The following is a list of chemical compounds that will form explosive peroxides under the right conditions, which can be detonated by shock or heat.

  • Diisopropyl ether
