These chemicals are dangerous because they are toxic to humans when inhaled, ingested, or absorbed through the skin. Long-term exposure can lead to health issues such as liver and kidney damage, neurological effects, and an increased risk of cancer. They can also harm the environment by contaminating soil and groundwater.
Interesting question...
Inhaling hot carbon tetrachloride is very dangerous as it reacts with oxygen in the air to make phosgene1) - a poisonous gas that was used as a chemical weapon in the first world war.
However
According to COSHH (the UKs Control of Substances Hazardous to Health) there is no short term (up to 15 minutes) exposure rate that is safe for carbon tetrachloride. In fact over an 8 hour period you shouldn't be exposed to more than 2ppm. Exposure can affect the nervous system, the liver and kidneys and cause coma and death. It might take a while, but a good lungful is going to be harmful to your health.
In short, if you have to pick between hot or cold carbon tetrachloride - pick cold. If you have a choice as to inhale or not inhale - then don't!
1) Comment:
This is more likely to be the case with chlororform(CHCl3), which is not the same as carbon tetrachloride (CCl4). But tetra is still as dangerous as described here.

Tetrachloroethylene, also known as perchloroethylene, is commonly found in dry-cleaning solutions, degreasing agents, and some spot removers. It is also used in manufacturing processes for textiles, metals, and rubber.
It could be imminently dangerous or dangerous in the future. It should be looked at by an engineer.
the weight which you can't handle is dangerous
since they are dangerous like you
I don't see anything dangerous in this - strange, yes, but not dangerous.
An alternative to trichloroethylene is tetrachloroethylene, also known as perchloroethylene (PERC). It is commonly used as a replacement solvent for degreasing and dry cleaning processes due to its similar properties but with fewer environmental and health concerns.
Tetrachloroethylene is not a nitrate.
Dry-cleaninguses perchloroethylene, trichloroethane and trichloroethylene.
The International Agency for Research on Cancer has classified tetrachloroethylene as a Group 2A carcinogen, which means that it is probably carcinogenic to humans. Tetrachloroethylene dissolves fats from the skin, potentially resulting in skin irritation. Animal studies and a study of 99 twins by Dr. Samuel Goldman and researchers at the Parkinson's Institute in Sunnyvale, California determined there is a "lot of circumstantial evidence" that exposure to Tetrachloroethlene increases the risk of developing Parkinson's disease ninefold.
C2Cl4
California has released the greatest quantity of trichloroethylene into the environment.
C2HCl3
Household chemicals such as bleach, ammonia, and hydrogen peroxide can have similar effects to chloroform in terms of being irritants to the respiratory system, skin, and eyes. Additionally, some household cleaners containing solvents like trichloroethylene or tetrachloroethylene may have similar health effects as chloroform when inhaled or used in confined spaces.
The name of c2cl3 is trichloroethylene.

No, trichloroethylene is not a heavy metal. It is a volatile organic compound commonly used as a solvent in various industrial processes. Heavy metals are elements like lead, mercury, and cadmium that have high atomic weights.
Trichloroethylene is a colorless, volatile liquid used as a solvent for cleaning metal and as a chemical intermediate in the production of other chemicals. It is also used in some consumer products like adhesives and paints. However, trichloroethylene is a known carcinogen and poses health risks if not handled properly.
