yes if you happen to look at them during blow up. the worst offenders are tantalum whereby they unwind in a long stream of metal
Because many electronics, like power supplies, have internal energy storage in the form of capacitors. If you were to short the terminals, you would be shorting out the internal capacitors and thus creating a potentially hazardous situation. "Completing the circuit by internal resistance" allows the energy stored in the internal capacitors to bleed off slowly because the internal resistance is larger than a short.
Electric arc welding produces intense ultraviolet light, which is very hazardous to eyes and skin.
To have an electrical design job, you absolutely must be knowledgeable about hazardous area electrical systems. You may also need Microstation experience, design experience, and experience in an engineering industry.
Switching light on/off through loosening from socket is not advisable. Light bulb can reach at temperature between 200-260 degrees Celsius and it can be hazardous in physical contact.
If you're asking whether you have to connect the fixture ground to the house ground, you do. The idea is to connect any exposed portion of a metal fixture to ground, keeping anything you would be able to touch from having a hazardous potential on it. The way to do this is to connect the fixture ground (which is connected to the metal chassis) to the building ground (which comes from your electrical panel).

Some hazardous chemicals can be made non-hazardous and some cannot.
You are allowed to mixed a non-hazardous waste with a hazardous waste
is aluminum hazardous
Marijuana is not hazardous.
hazardous waste proliferation is the rapid increasing of hazardous waste.
The short answer is no, but be careful anyway. The board itself is made of paper and epoxy resin which is not toxic but is not good for you. The real problem is the components on the board and the solder. All solder on older boards will contain lead, but most newer boards use lead free solder as much as possible. Electrolytic capacitors if they burst can release corrosive chemicals and many other components contain mercury, gold, silver and various heavy metals. In other words don't eat it and be sure to wash your hands after handling before you eat or smoke. There are often flame retardants that are hazardous (carcinogenic) in PC boards.
Yes, it is hazardous.
I think Hazardous Chemicals I think Hazardous Chemicals I think Hazardous Chemicals
Yes. Hazardous is opposite of safety. Safety having no danger where hazardous is a risk or danger.
Misidentification could be hazardous.
The word "hazardous" is an adjective.
