Synergy can Disposal of Methane (CH₄)

Overview

  • Chemical Formula: CH₄

  • Description: Methane is a colorless, odorless, and highly flammable gas. It is the simplest alkane and the main component of natural gas.

  • Sources: Methane is produced both naturally and through human activities. Natural sources include wetlands and the digestive processes of ruminant animals. Human activities producing methane include fossil fuel extraction, livestock farming, and landfills.

Label Information

  • Contents: The canister contains methane (CH₄).

  • UN Number: 1971

    • Purpose of UN Number: The United Nations number 1971 is used to identify methane gas for transport and emergency response purposes.

  • Hazard Symbol:

    • Flammable Symbol: The label features a flammable hazard symbol (typically a flame icon) indicating that methane is highly flammable.

  • Warning Information:

    • Flammable Nature: Methane is highly flammable and can form explosive mixtures with air. It is essential to handle the gas with care to prevent ignition.

    • Handling Instructions:

      • Avoid Ignition Sources: The gas should be kept away from open flames, sparks, and other sources of ignition.

      • Ventilation: Use in well-ventilated areas to prevent the accumulation of gas.

      • Static Discharge: Ground all equipment to prevent static electricity buildup, which could ignite the gas.

    • Emergency Procedures: The label may also include instructions for emergency situations, such as evacuating the area in the event of a gas leak and contacting emergency services.

Physical and Chemical Properties

  • Appearance: Colourless gas.

  • Odour: Odourless (although an odorant like mercaptan is often added for leak detection).

  • Boiling Point: -161.5°C (-258.7°F)

  • Melting Point: -182.5°C (-296.5°F)

  • Density: Lighter than air, with a density of 0.656 kg/m³ at 0°C.

Health and Safety Effects

  • Asphyxiation Risk: While methane itself is not toxic, it can displace oxygen in the air, leading to asphyxiation in confined spaces.

  • Explosive Risk: Methane forms explosive mixtures with air within the concentration range of 5% to 15%.

  • Burning: Combustion of methane produces carbon dioxide and water vapor. Incomplete combustion can produce carbon monoxide, a toxic gas.

Safety Measures

  • Storage: Store in a cool, dry, and well-ventilated place away from sources of ignition and direct sunlight. Ensure storage areas are equipped with proper fire suppression systems.

  • Handling: Handle with care to prevent leaks. Use appropriate leak detection methods, such as gas detectors, and regularly inspect equipment.

  • Protective Equipment: Use flame-resistant clothing and equipment when handling methane gas. Ensure that all personnel are trained in handling flammable gases and emergency response procedures.

The methane canister, identified by UN number 1971, contains highly flammable methane gas (CH₄). Proper handling and usage instructions are critical to prevent accidental ignition and explosions. Adequate ventilation, grounding of equipment, and adherence to safety protocols are essential when using or storing this gas.
