What are the hazards of a broken capacitor
The two primary hazards addressed by electrical workers today are shock and arc flash. Because the hazards are different, the techniques, boundaries, and PPE must address the risks associated with both types of hazards. Following the guidance in Sec. 130.4(A), a simplified approach to shock hazard analysis is:

$begingroup$ In case somebody ever has to deal with such a mess in ancient or military surplus equipment: a) There seem to have been a few (very few) types of electrolytic capacitors in the 70s and earlier that had polychlorinated biphenyls added (far more common in non electrolytics!) b) so called wet slug tantalum types (uncommon in non-military/aerospace …
The Importance of Safety Capacitors in Power Electronics
Y Capacitors: Class-Y capacitors, also known as "line-to-ground capacitors" or "line bypass capacitors," offer line-to-ground protection, which generally means that if a failure with the ground occurs, there is a risk for shock. However, Class-Y safety capacitors must meet rigorous specifications, minimizing the chance of electric shock.

Capacitor in Electronics – What It Is and What It Does
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
