What safety measure should be taken when dealing with a swollen capacitor?

When dealing with a swollen capacitor, treating it as potentially explosive is essential due to the risks involved. A swollen capacitor indicates that it is experiencing internal pressure buildup, which can occur due to overheating, failure of the dielectric material, or other issues. This situation can lead to catastrophic failure, including rupture or explosion, which can cause injury or damage.

Proper precautions involve handling the swollen capacitor carefully, maintaining a safe distance, and using protective gear when necessary. Moreover, it’s crucial to follow established safety protocols, such as discharging the capacitor if possible, before attempting any further action. This approach ensures that personnel are protected from the hazards associated with the capacitor's failure.
