1,3-Butadiene (C4H6) Valve Shutoff System

About 1,3-Butadiene

1,3–Butadiene is a flammable, colorless toxic gas with a pungent odor similar to that of gasoline at standard temperature and pressure. It is considered a "probable carcinogen" by the Environmental Protection Agency and a known carcinogen by the Agency for Toxic Substances & Disease Registry. Breathing very high levels of 1,3-butadiene for a short time can cause central nervous system damage, blurred vision, nausea, fatigue, headache, decreased blood pressure and pulse rate, and unconsciousness.

According to the United States Department of Labor Occupational Safety & Health Administration (OSHA), 1, 3-Butadiene ranks 36th in the most produced chemicals in the United States. Three billion pounds per year are produced in the U.S. and 12 billion globally. Approximately 75% of all 1.3–Butadiene is used in the production of synthetic rubber. It is also used in making plastic.

Characteristics of 1,3-Butadiene

Synonyms: 1,3-Butadiene (BD), butadiene, biethylene; bivinyl, divinyl, butadiene-1,3, buta-1,3-diene, erythrene, vinylethylene, NCI-C50620, CAS-106-99-0.
Physical Attributes: Colorless gas with a pungent odor similar to gasoline when at standard temperature and pressure.
Molecular Formula: C4H6
Molecular Weight: 54.09
Boiling Point: 24°F (-4.41°C).
Specific Gravity: 0.62 (liquid) at 68°F (20°C) (water = 1.00)
Flammable: 1,3-Butadiene is highly flammable. Because 1,3-Butadiene is heavier than air, it has the potential of reaching a source of ignition over a great distance.
Note: Because of 1,3-butadiene's physical properties (e.g., low flashpoint and tendency to polymerize), its fire and explosion potential might be greater concerns (more likely to occur and more dangerous) than its health effects.

1,3-Butadiene is also known as biethylene, bivinyl, divinyl B, erythrene, and vinylethylene.

Recommendations for the Safe Handling of 1,3 Butadiene

All necessary safety precautions recommended for the handling of a flammable, compressed gas must be observed. As outlined in the Handbook of Compressed Gases (4th ed. Compressed Gas Association), in the event of a 1,3 Butadiene leak, the leak should be shutdown if it can be done safely, without risk to personnel.

Powell Valve Closure Systems are designed to prevent significant releases of hazardous gases like 1,3-Butadiene. In the case of an accidental release, the emergency valve closure system will automatically close the container valves in seconds, effectively preventing a reportable release regardless of where the leak occurs downstream.
