If leaking containers of perchloric acid and other chemicals are discovered, the best course of action is to:

The most appropriate response when discovering leaking containers of perchloric acid and other chemicals is to call an experienced HAZMAT team. This is primarily because perchloric acid is a strong oxidizer and can pose significant safety hazards, including potential for fire or explosion when it comes in contact with organic materials or certain other substances.

A HAZMAT team is specially trained to handle hazardous materials and manage emergency situations effectively. They have the necessary equipment, knowledge, and procedures to safely contain, clean up, and dispose of hazardous substances while minimizing risks to health and the environment. Their expertise ensures that the situation is managed correctly to avoid exposure to harmful chemicals.

Attempting to contain the leak oneself can lead to inadequate handling and increased risk of exposure or accidents, especially if one is not familiar with the chemical properties and risks involved. Notifying on-site management alone would not suffice, as they may not have the specialized training required for hazardous materials. Leaving the containers alone is also inappropriate, as delaying action can exacerbate the situation, increasing the risk of wider contamination or injury.
