What is the IDLH for vinyl chloride?
Conversion. 1 ppm = 2.56 mg/m3. IDLH.
What is the regulatory limit for vinyl chloride?
Vinyl chloride is regulated in drinking water, food, and air. Because it is a hazardous substance, regulations on its disposal, packaging, and other forms of handling also exist. EPA requires that the amount of vinyl chloride in drinking water not exceed 0.002 milligrams per liter (mg/L) of water (0.002 ppm).
What is vinyl chloride used for?
Vinyl chloride is a colorless, flammable gas that evaporates very quickly. It’s used to make polyvinyl chloride (PVC) pipes, wire coatings, vehicle upholstery, and plastic kitchen ware.
What is the critical temperature of vinyl chloride?
By these methodsthe estimated critical pressure is 52.2 atm. while the estimated critical temperature is 142°.
What is Lel of vinyl chloride?
Lower Explosive Limit (LEL) = 38000 ppm.
Why is vinyl chloride hazardous?
Vinyl chloride can irritate the eyes, mucous membranes, and respiratory tract. Escaping compressed gas or liquid can cause frostbite or irritation of the skin and eyes. Chronic exposure can cause permanent liver injury and liver cancer, neurologic or behavioral symptoms, and changes to the skin and bones of the hand.
How do you prevent vinyl chloride?
What are the top tips to avoid exposure? Limit use of PVC plastic containers and food packaging, as they may have traces of vinyl chloride. Industrial workers in close contact with vinyl chloride should use respirators and wear protective clothing.
What are the effects of vinyl chloride?
Health Effects. The primary target of vinyl chloride acute exposure is the CNS. Signs and symptoms include dizziness, ataxia, inebriation, fatigue, numbness and tingling of the extremities, visual disturbances, coma, and death. Vinyl chloride can irritate the eyes, mucous membranes, and respiratory tract.
What is another name for vinyl chloride?
chloroethylene
vinyl chloride, also called chloroethylene, a colourless, flammable, toxic gas belonging to the family of organohalogen compounds and used principally in making polyvinyl chloride, or PVC, a widely used plastic with numerous applications.
What is vinyl chloride stabilized?
Vinyl chloride is an organochloride with the formula H2C=CHCl. It is also called vinyl chloride monomer (VCM) or chloroethene. This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC).
Is vinyl the same as PVC?
Vinyl is commonly used as a shorthand name for polyvinyl chloride (PVC) plastic as used in a range of products from flooring to siding to wall covering. Most commonly, when a product is referred to as “vinyl,” it is comprised primarily of PVC.
Is vinyl chloride a VOC?
Vinyl chloride belongs to the group volatile organic compounds (VOC). Vinyl chloride is a colourless gas with a characteristic sweetish odour. It is classified as very flammable.
How do you remove vinyl chloride from water?
Installation of an in-home activated carbon filter can remove most of the vinyl chloride from water. Using bottled water also will reduce exposure. If you use contaminated water for other uses in the home (i.e. bathing, and washing dishes), ventilate bathrooms, washrooms and kitchens during and after water use.
Is VCM toxic?
VCM is a halogenated hydrocarbon with acute toxic effects, as well as chronic carcinogenic effects.
How is VCM produced?
There are two methods to produce VCM: direct chlorination and oxychlorination. Direct chlorination sees ethylene and chlorine react within a catalyst-containing reactor to form EDC. EDC is then thermally cracked to yield VCM at a few hundred degrees Celsius.
Whats stronger PVC or vinyl?
Vinyl is a polymer and PVC is a thermoplastic. Both PVC and vinyl have their pros and cons. PVC, for instance, is more durable, but it’s also more toxic than vinyl. PVC is stronger than vinyl because PVC has higher tensile strength and compressive strength.
Is vinyl safer than PVC?
Keep in mind the term “vinyl” may also be used to describe ethylene vinyl Acetate (EVA) and polyethylene Vinyl Acetate (PEVA). Both of these plastics are non-chlorinated and are considered to be a safer alternative to PVC and are acceptable choices.
Is vinyl chloride in water bottles?
What is wrong with PEVA?
For the first time, our results have shown that PEVA plastic has adverse effects on living organisms, and therefore it is not a safe alternative to PVC. Further studies should identify specific compounds causing the adverse effects, and determine whether toxic effect occurs in more complex organisms, especially humans.
Does reverse osmosis remove vinyl chloride?
Water Treatment for Vinyl Chloride
Vinyl chloride can be treated with granular activated carbon combined with reverse osmosis, some distillation methods, and air stripping.
Is VCM gas or liquid?
gas
Vinyl Chloride Monomer (VCM) is a colorless, flammable gas at room temperature. At concentrations of about 3.6 percent VCM in air, VCM can be an explosion hazard. VCM is often stored as a liquid under pressure. The liquid evaporates readily at ambient temperatures.
Why is vinyl chloride toxic?
What is VCM material?
Vinyl Chloride Monomer (VCM) is a colorless, flammable gas at room temperature. Its chemical formula is C2H3Cl. It is primarily used to manufacture polyvinyl chloride (PVC), a very stable, non-flammable, lightweight and durable plastic. PVC is used in a variety of applications.
Is VCM soluble in water?
Physical properties
VCM is soluble in many organic solvents but is not soluble in water.
What is the difference between polyvinyl chloride and vinyl chloride?
Polyvinyl chloride, denoted as PVC, is a synthetic polymer produced by the monomer vinyl chloride. Vinyl chloride is an alkene derivative containing a substituted chlorine atom instead of a hydrogen atom. In the production of PVC, an addition polymerization takes place by arranging the monomers in head to tail fashion.
