How to store acetone and paint

Proper storage of chemical reagents is one of the most important regulatory measures to be taken by any business or laboratory with a chemical inventory. Acetone, as one of the most ubiquitous chemical solvents, is no exception.
Proper storage of chemical reagents entails:

• Keeping careful records of all chemical inventory
• Separating reactive chemicals during storage
• Storing flammable chemicals in a flammable-safe cabinet
• Storing volatile chemicals in well-ventilated areas
• Keeping track of the shelf life and expiration of all chemicals
• Storing reagents at the correct temperature
• Having proper personal protective equipment on hand if needed
• Having emergency facilities on hand if needed (for example, an eye wash and a shower)

All chemicals come with specifications and a “Material Safety Data Sheet” (MSDS) detailing the storage and handling requirements, as well as the associated hazards of that chemical. Closely adhering to the appropriate safety precautions is essential to the health and safety of the workers and the environment.

What is acetone?

Acetone, also known as dimethyl ketone, is a common solvent. It exists as a clear and colorless liquid with a pungent odor, which is most readily associated with nail polish remover. In fact, acetone is a common ingredient in many nail polish remover formulations, since it is very effective at dissolving paint. It evaporates quickly and is miscible with water.

What is acetone used for?

Acetone has multiple uses in industrial and laboratory settings, including:

• Cleaning substance
• Food packaging
• Cosmetic formulations
• Superglue component
• Manufacture of plastics and fibers
• Pharmaceutical manufacture
• Paint remover
• Paint thinner

What is the shelf life of acetone?

If stored correctly, tightly sealed in the original container, acetone is not likely to degrade. In fact, it is expected to have an indefinite shelf life. Storing acetone correctly can therefore save your business or laboratory on unnecessary repurchase costs. If exposed to excessive heat, acetone will decompose to produce acrid fumes of carbon oxides. It is important to store acetone away from heat or ignition sources.

How should acetone be stored?

Although it is a stable compound, acetone still has safety hazards and incompatibilities that must be considered.

The primary safety concern with acetone is that it is highly flammable. Acetone must be stored in a flammable-proof cabinet. As we mentioned above, acetone should never be exposed to heat or ignition sources. There is no need to refrigerate acetone. Storing in a cool dry area with adequate ventilation will suffice to prolong the shelf life and ensure safety.

Secondly, acetone should be stored separately from any incompatible chemicals. Incompatible chemicals include:

• Oxidizers
• Chloroform
• Chromic anhydride
• Hydrogen peroxide
• Nitric compounds
• Acids

Safe handling of acetone

Acetone is toxic to the central nervous system upon ingestion or even inhalation. Since the fumes of acetone can be very potent, it is important to always work in a well-ventilated area such as a fume hood when handling acetone. Toxic effects can be a result of both acute and chronic exposure. Always wear the appropriate personal protective equipment, including safety goggles, gloves, and lab coat or chemical-resistant clothing. Additionally, the space should be equipped with an eye wash, shower, and fire extinguisher prior to handling acetone.

How to dispose of acetone

Acetone should be disposed of in a properly labeled chemical waste container (this is often a re-labeled, emptied solvent bottle). You can schedule pick-up with a company that handles hazardous waste. Regulations may vary between jurisdictions, so be sure to check that you comply.

How should paint be stored?

Acetone is not only used as a paint removal aid; it is also sometimes used as a paint thinner. Therefore, paints containing acetone must also comply with safe storage regulations. Paints are often flammable, heat-sensitive, and can produce noxious fumes. Proper storage is essential to your health and safety, as well as prolonging the shelf life of your products. Like acetone itself, paint should be stored away from heat and ignition sources to mitigate the risk of fire. Ideally, the paint will be stored in a flammable-proof cabinet, in a dry, cool, and well-ventilated area. You may need to arrange climate control and mechanical ventilation.
