How should you store opened containers of chlorates?

1. Store away from other pesticides

2. Store in an airtight container

3. Do not store at all

4. Store in a cool, dry place

The correct answer is: Do not store at all

Opened containers of chlorates should not be stored at all due to their highly reactive nature. Chlorates are strong oxidizers, which means they can easily react with organic materials and other chemicals, potentially leading to hazardous situations such as fires or explosions. The safest practice is to use chlorates as needed and promptly dispose of any remaining product in accordance with local regulations. On the other hand, if chlorates were stored away from other pesticides, in an airtight container, or in a cool, dry place, there still exists a risk of inadvertent reactions with residual materials, moisture, or even atmospheric conditions that could compromise safety. Not storing these substances after they have been opened eliminates risks associated with prolonged storage and minimizes the potential for chemical reactions. Therefore, immediate disposal or proper usage is the best practice when it comes to handling opened containers of chlorates.
