Synergy can Disposal of 2-Methylpropene

2-Methylpropene Gas Cylinders

Chemical Formula: C₄H₈

Description: 2-Methylpropene, also known as isobutane, is a colourless, highly flammable gas with a faint petroleum-like odour. It is widely used in the production of various chemicals, including plastics and synthetic rubber.

Label Information

  • Contents: The gas cylinder contains 2-Methylpropene (C₄H₈).

  • UN Number: 1055

    • Purpose of UN Number: UN 1055 is used to identify 2-Methylpropene for safe transport, storage, and emergency response purposes.

Hazard Symbols

  • Flammable Symbol: A flammable hazard symbol is present on the label, indicating that 2-Methylpropene is highly flammable and can form explosive mixtures with air.

  • Health Hazard Symbol: The label may include a health hazard symbol (exclamation mark) to warn of potential health risks, such as irritation or more severe health effects upon exposure.

Warning Information

  • Respiratory Protection: Users are advised to wear proper respiratory protection to avoid inhalation, as exposure can cause respiratory issues.

  • Handling Instructions: The gas should be handled with great care due to its flammable nature. Use in well-ventilated areas or under controlled conditions, and keep away from sources of ignition.

  • Emergency Procedures: In case of exposure, such as inhalation, move the affected person to fresh air and seek medical attention immediately.

Physical and Chemical Properties

  • Appearance: Colourless gas.

  • Odour: Faint petroleum-like smell.

  • Boiling Point: -6.9°C (19.6°F)

  • Melting Point: -140.4°C (-220.7°F)

  • Density: Lighter than air, with a density of 0.588 g/L at 0°C.

Health Effects

  • Acute Exposure: Inhalation can cause respiratory irritation, dizziness, drowsiness, and headache. In high concentrations, it may lead to asphyxiation. Skin or eye contact can result in mild irritation.

  • Chronic Exposure: Long-term exposure may contribute to central nervous system depression and respiratory issues.

Reactivity and Compatibility

  • Polymerisation: 2-Methylpropene is relatively stable but can polymerise in the presence of acids or heat, potentially leading to hazardous conditions.

  • Incompatible Materials: It is incompatible with strong oxidisers and acids, which can cause dangerous reactions, including fire and explosion.

Environmental Impact

  • Air and Water: If released into the environment, 2-Methylpropene can contribute to air pollution, forming ground-level ozone. It may also contribute to smog formation.

  • Ecosystems: It is harmful to aquatic life with long-lasting effects and may pose risks to the environment if released in large quantities.

Safety Measures

  • Storage: Store gas cylinders in a cool, dry, and well-ventilated location, away from sources of heat, sparks, or open flames. Cylinders should be stored upright and secured to prevent tipping.

  • Handling: Ensure cylinders are regularly inspected and that leak detection methods are used. Handle with care to avoid physical damage to the cylinder, and always use in areas with sufficient ventilation.

  • Protective Equipment: Personal protective equipment (PPE) such as gloves, safety goggles, and flame-resistant clothing should be used when handling 2-Methylpropene. Use appropriate respirators if ventilation is inadequate.

Regulatory Information

  • Occupational Exposure Limits: Various health and safety authorities have set exposure limits for 2-Methylpropene to reduce the risk of harmful effects on workers.

  • Transport Regulations: 2-Methylpropene must be labelled and packaged according to international transport regulations, including those set by the International Air Transport Association (IATA) and the International Maritime Organisation (IMO). Transport in approved containers to prevent leaks or accidental release.
