Counterfeit Goods: A Danger to Public Safety | ICE
"At best, these products will not perform as well as authentic products. At worst, they can fail catastrophically." Some of the most dangerous counterfeit products involve automotive parts, electronics, safety equipment, prescription drugs, and cosmetics due to the potential threats they present to public safety and public health:
How Capacitors Work
A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons. One amp represents a rate of electron flow of 1 coulomb of electrons per second, so a 1-farad capacitor can hold 1 amp-second of electrons at 1 volt. A 1-farad capacitor would typically be pretty big.

Solved Large capacitors can hold a potentially dangerous
Question: Large capacitors can hold a potentially dangerous charge long after a circuit has been turned off, so it is important to make sure they are discharged before you touch them. Suppose a 120 μF capacitor from a camera flash unit retains a voltage of 150 V when an unwary student removes it from the camera.
Do Capacitors reside under the dangerous good regulations.(DGR)?
Amendments were made to the DGR since 2014. From 2015 (IATA Dangerous Goods Regulations 56th edition) a new entry UN 3508, Capacitor, asymmetric has been added, and the existing proper shipping name "capacitor" for UN 3499 has been revised to become Capacitor, electric double-layer, which covers the supercapacitors or ultracapacitors.
Are capacitors dangerous?
Capacitors themselves are not inherently dangerous, but they can be if mishandled or used improperly. Capacitors are electronic components that store electrical energy in an electric field. Here are some potential dangers associated with capacitors: 1.
Applications of capacitors
Capacitors may retain a charge long after power is removed from a circuit; this charge can cause dangerous or even potentially fatal shocks or damage connected equipment. For example, even a seemingly innocuous device such as a disposable camera flash unit powered by a 1.5 volt AA battery contains a capacitor which may be charged to over …

Your 4700u cap question has no reference without a voltage. The energy in joules a capacitor has available is 1/2 CV^2 where C is the capacitance in Farads and V is the voltage. Capacitors can discharge their energy VERY fast so they become exponentially more dangerous as the voltage increases.
