Chloromethane Disposal

Label Information Contains chloromethane (CH₃Cl).

The UN number is 1063.

The hazard symbol indicates that it is highly flammable and harmful if inhaled.

Ensure proper respiratory protection and handle with care due to its potential harmful effects.

Overview

  • Chemical Formula: CH₃Cl

  • Description: Chloromethane is a colourless, flammable gas with a faint sweet odour. It is toxic if inhaled and poses a significant fire hazard.

  • Sources: It is used primarily as a refrigerant, in the production of silicone polymers, and as a chemical intermediate in various industrial processes.

Label Information

  • Contents: The canister contains chloromethane (CH₃Cl).

  • UN Number: 1063

  • Purpose of UN Number: The United Nations number is a four-digit code used internationally to identify hazardous substances during transport and emergency situations.

Hazard Symbol

  • Flammable and Toxic Symbol: The label includes symbols indicating that chloromethane is both flammable and harmful, warning of its toxic effects when inhaled and its risk of causing fires.

Warning Information

  • Respiratory Protection: Users are advised to wear proper respiratory protection to prevent inhalation of the gas, as it can lead to serious health effects.

  • Handling Instructions: Handle with caution, ensuring proper ventilation and keeping the substance away from sources of ignition. It should be used only in controlled environments with appropriate safety equipment.

  • Emergency Procedures: In case of exposure, move the person to fresh air immediately and seek medical assistance.

Physical and Chemical Properties

  • Appearance: Colourless gas.

  • Odour: Faint sweet smell.

  • Boiling Point: -24.2°C (-11.6°F)

  • Melting Point: -97.7°C (-143.9°F)

  • Density: Slightly heavier than air, with a density of 2.22 kg/m³ at 25°C.

Health Effects

  • Acute Exposure: Inhalation of chloromethane can cause dizziness, headache, nausea, confusion, and in severe cases, loss of consciousness or death.

  • Chronic Exposure: Prolonged or repeated exposure may lead to damage to the central nervous system, liver, and kidneys.

Safety Measures

  • Storage: Store in a cool, dry, and well-ventilated area, away from sources of heat, sparks, or open flames.

  • Handling: Use in areas with adequate ventilation. Ground all equipment to prevent static discharge, which could ignite the gas.

  • Protective Equipment: Ensure proper use of PPE, including gas detectors and respirators, to monitor exposure levels and avoid inhalation.

Chloromethane, identified by UN number 1063, is a highly flammable and toxic gas. Strict safety measures, including proper ventilation, respiratory protection, and safe handling, are essential to prevent accidents. Always follow manufacturer guidelines and emergency procedures to minimise health risks and fire hazards.
