Is butadiene harmful to humans?

Acute (short-term) exposure to 1,3-butadiene by inhalation in humans results in irritation of the eyes, nasal passages, throat, and lungs. Animal studies have reported tumors at various sites from 1,3-butadiene exposure. EPA has classified 1,3- butadiene as carcinogenic to humans by inhalation.

Is butadiene a hazardous material?

► 1,3-Butadiene is a PROBABLE CARCINOGEN in humans. There is some evidence that it causes lymph and blood cancer in humans and it has been shown to cause lymph, breast, uterine, lung, heart, and skin cancer in animals. a carcinogen. ► 1,3-Butadiene causes MUTATIONS (genetic changes).

What are the side effects of exposure to 1/3-butadiene?

Acute high exposures may cause damage to the central nervous system or cause symptoms such as distorted blurred vision, vertigo, general tiredness, decreased blood pressure, headache, nausea, decreased pulse rate, and fainting. Chronic effects caused by exposure to 1,3-butadiene are controversial.

What facts are true about 1,3-butadiene?

1,3-Butadiene is a chemical made from the processing of petroleum. It is the 36th highest volume chemical produced in the United States. It is a colorless gas with a mild gasoline-like odor. About 75\% of the manufactured 1,3-butadiene is used to make synthetic rubber.

How do you make chloroprene?

Chloroprene is produced in three steps from 1,3-butadiene: (i) chlorination, (ii) isomerization of part of the product stream, and (iii) dehydrochlorination of 3,4-dichlorobut-1-ene.

Is SBR rubber toxic?

The rubber is not irritant or toxic. Decomposition products (amethyl-styrene) irritate eyes, skin, and respiratory system.

What does chloroprene look like?

Tensile strength defines the ability of a material or product to withstand tension forces without breakage. Chloroprene has good tensile strength and will handle tension pressure will. It is also important to note that the material displays exceptional elongation performance.

Is chloroprene toxic?

* Exposure to high concentrations can cause dizziness, lightheadedness and passing out. * Chloroprene may be a CARCINOGEN in humans since it has been shown to cause liver and lung cancer in animals.

What are the health effects of exposure to 1-3-butadiene?

The health effects caused by exposure to 1,3-butadiene can be split into two categories: acute and chronic. Acute exposures can further be split into low and high doses. Acute low exposures may cause irritation to the eyes, throat, nose, and lungs. Frostbite may also occur with skin exposure.

What is the IDLH for 1 3 butadiene?

However, the revised IDLH for 1,3-butadiene is 2,000 ppm based strictly on safety considerations (i.e., being 10\% of the lower explosive limit of 2\%). [Note: NIOSH recommends as part of its carcinogen policy that the “most protective” respirators be worn for 1,3-butadiene at any detectable concentration.] AIHA [1963]. 1,3-Butadiene.

What is the CACAS number for 1 3 butadiene?

CAS number: 106-99-0. NIOSH REL: None established; NIOSH considers 1,3-butadiene to be a potential occupational carcinogen as defined by the OSHA carcinogen policy [29 CFR 1990].

What is the OSHA PEL for butadiene?
