What precautions should be taken for chemicals with a high flammability hazard?

For chemicals with a high flammability hazard, it is crucial to keep them stored in approved containers. Approved containers are specifically designed to safely hold and minimize the risk of spills, leaks, or reactions that could result from exposure to fire or heat sources. These containers often have characteristics such as being made of flame-retardant materials or having features that prevent ignition sources from penetrating the container.

This practice is part of a broader strategy of chemical safety that aims to mitigate risks associated with handling and storing hazardous substances. Approved containers ensure compliance with safety regulations and standards, thereby helping prevent accidental ignition or explosive reactions that can occur if flammable chemicals are stored improperly.

The other options provided do not address the essential aspect of using suitable containers specifically designed for chemicals with high flammability hazards. Storing in non-combustible areas, while important for fire safety, is not as specific as using approved containers. Limiting the quantity to less than a quart may not be practical or sufficient for all situations, and keeping chemicals in open containers for ventilation actually increases the risk of fire and should be avoided.
