How To Store Chemicals Safely

10 Essential Tips On How Chemicals Should Be Stored

Proper chemical storage is crucial for safety, environmental protection, and preserving the chemical’s quality and usability. Here are 10 essential tips on how chemicals should be stored:

1. Read the Material Safety Data Sheet (MSDS)

The Material Safety Data Sheet, or MSDS, is a vital document that accompanies any hazardous chemical or substance. It contains comprehensive information about the chemical’s identity, physical and chemical properties, health and safety hazards, emergency response procedures, and disposal considerations.

Before storing any chemical, it’s imperative to consult its MSDS. This document will offer insights into the chemical’s volatility, reactivity, flammability, and other crucial characteristics determining its storage needs. Ignoring the MSDS can lead to misinformed decisions about storage, resulting in harmful or even catastrophic consequences.

2. Store Incompatible Chemicals Separately

Many chemicals can react dangerously when they come into contact with specific other chemicals. For instance, mixing acids with bases can result in vigorous reactions producing heat, gas, and possibly splattering. Similarly, oxidizers can provide oxygen to flammables, leading to rapid combustion.

Water-reactive substances, on the other hand, can release gases or even explode when exposed to moisture. As such, it’s paramount to segregate chemicals based on their compatibility. Keeping them separate can prevent unplanned and hazardous reactions which could jeopardize safety.

3. Use Proper Containers

The integrity and compatibility of the container holding a chemical are as important as the location where it’s stored. Chemicals should ideally remain in their original containers since these are designed specifically for their content.

However, if transferring is necessary, the new container must be made of a material that does not react with the chemical. It’s also essential that the containers are undamaged, correctly labeled with the chemical’s name and potential hazards, and always securely sealed. A compromised container can lead to leaks, spills, and exposure to harmful chemicals.

4. Limit Quantity

Storing large amounts of chemicals amplifies risks. More substantial quantities in a spill or accident can mean bigger fires, more significant environmental damage, or more severe health implications. Limiting the amount of stored chemicals to only what is necessary for a specific duration or project significantly reduces risks associated with accidents or mishandling. Moreover, storing fewer chemicals also means less financial loss in a mishap.

5. Use Ventilated Storage

Many chemicals, especially solvents and volatile compounds, release vapors. Over time, these vapors can accumulate to levels that pose health risks when inhaled. Some vapors can also form explosive mixtures in the air. It’s thus vital to store such chemicals in areas with adequate ventilation.

This ensures that any released vapors are quickly dispersed, reducing the chances of inhalation or the formation of explosive atmospheres. Cabinets or rooms designed for chemical storage often incorporate ventilation systems that constantly renew the air, preventing the buildup of hazardous vapors.

6. Keep Chemicals at the Appropriate Temperature

Maintaining the right temperature is crucial for the stability and integrity of many chemicals. When exposed to temperatures beyond their recommended range, some chemicals might degrade, become less effective, or even form hazardous byproducts. While refrigeration can be essential for preserving certain chemicals, it’s crucial to differentiate between regular refrigerators and those designated for chemicals. Common refrigerators used for food storage might not provide consistent temperatures, and there’s the risk of contamination.

Additionally, extreme temperatures, whether too cold or too hot, can impact the container’s structure, possibly leading to leaks or breakages. It’s also worth noting that some chemicals can become more volatile or reactive if they undergo temperature fluctuations.

7. Ensure Proper Labeling

Labeling is the first line of information for anyone handling a chemical. An unlabeled or mislabeled container can be a significant hazard because users might be unaware of its contents and associated risks.

A proper label should provide the chemical’s name, concentration, potential hazards, and basic handling recommendations. In cases where a chemical is transferred to another container, it is paramount to label this new container instantly. This immediate action ensures no period during which the container’s contents are unidentified, reducing the risk of accidents or misuse.

8. Avoid Floor Storage

Storing chemicals directly on the floor exposes them to various risks. They are more likely to be knocked over, leading to spills. Additionally, in the event of a flood or other water intrusion, chemicals on the floor are at higher risk of contamination or release.

Using designated storage solutions, like shelves or cabinets, elevates chemicals and adds a layer of protection. It’s essential to remember that the storage structure’s stability is crucial. Heavy or large containers should always be on lower shelves to reduce the risk of them toppling over and causing spills or injuries.
