Why is carbon tetrachloride not recommended as a fire extinguishing agent?

Carbon tetrachloride is a suspected carcinogen. Carbon tetrachloride will not burn (hence its use as a fire extinguishing agent). It has a specific gravity of 1.585, a molecular weight of 153.8, and a vapor density of 5.3. It freezes at — 9.4°F, boils at 170.2°F, and is practically insoluble in water.

Why the use of carbon tetrachloride as fire extinguisher is not very safe?

CARBON TETRACHLORIDE is a commonly used liquid in fire extinguishers to combat small fires. It has no flash point, it is not flammable. However, when heated to decomposition, it will emit fumes of extremely toxic phosgene and of hydrogen chloride.

How does carbon tetrachloride extinguish fire?

It is effective, due to the blanketing effect of its vaporized fumes, on many Class B or volatile, flammable liquid fires and because it will mix with certain volatile, flammable liquids and form a non-burning combination. It is one of the best-known reagents for extinguishing Class C or electrical fires.

What is the major danger from carbon tetrachloride?

Human symptoms of acute (short-term) inhalation and oral exposures to carbon tetrachloride include headache, weakness, lethargy, nausea, and vomiting. Acute exposures to higher levels and chronic (long-term) inhalation or oral exposure to carbon tetrachloride produces liver and kidney damage in humans.

Is carbon tetrachloride a flammable liquid?

Carbon tetrachloride (Carbon tet) is a non-flammable colorless liquid with a heavy, sweet odor.

What danger to personnel exists when a carbon dioxide fire extinguisher is discharged in a small enclosed space?

When a CO2 extinguisher is used in a confined space there is danger that the user may become overwhelmed by the sudden increase in carbon dioxide emissions. This occurs as CO2 is an asphyxiant, and the confined space means oxygen will be replaced by the CO2 much faster.

What is the important characteristics of the extinguishing agent in fighting a Class C fire?

The extinguishing agent in a Class C fire extinguisher must be electrically nonconductive. Both carbon dioxide and dry chemicals can be used for electrical fires. An advantage of carbon dioxide is that it leaves no residue after the fire is extinguished.

When water fog is used as an extinguishing agent the fire is extinguished principally by the?

Water and foam fire extinguishers extinguish the fire by taking away the heat element of the fire triangle. Foam agents also separate the oxygen element from the other elements. Water extinguishers are for Class A fires only; they should not be used on Class B or C fires.

What is CCl4 used for?

Carbon tetrachloride is used for dry cleaning, degreasing metals, fumigating, manufacturing refrigerants and aerosol propellants, and is also used in fire extinguishers. CCl4 is a possible carcinogen; inhalation or ingestion can cause damage to the brain, liver, kidneys, and can even cause death.

Is carbon tetrachloride a hazardous waste?

Tetrachloride as a HAZARDOUS WASTE. Contact your state Department of Environmental Protection (DEP) or your regional office of the federal Environmental Protection Agency (EPA) for specific recommendations. Prior to working with Carbon Tetrachloride you should be trained on its proper handling and storage.

Have carbon tetrachloride as part of the cargo if a fire breaks out in the general area what is the major danger from the carbon tetrachloride?

Deck – Safety #622 | U.S. Coast Guard Questions and Answers – USCGQ.com. You have carbon tetrachloride as part of the cargo. If a fire breaks out in the general area, what is the major danger from the carbon tetrachloride? A) It will burn rapidly once ignited.

Why carbon tetrachloride is a liquid but does not conduct electricity?

Carbon tetrachloride is a liquid and does not conduct electricity because it is a covalent compound and there are no free ions present and contain only molecules.

Which hazard does not apply to methanol?

Possible hazardous reactions:None under normal processing. Conditions to avoid:Excess heat, Incompatible Materials, flames, or sparks. Incompatible materials: Oxidizing agents, reducing agents, alkali metals, acids, sodium, potassium, metals as powders, acid chlorides, acid anhydrides, powdered magnesium, and aluminum.

Is carbon tetrachloride organic or inorganic?
