Synergy can Disposal of Boron Trichloride (BCl₃)

Overview

  • Chemical Formula: BCl₃

  • Description: Boron trichloride is a colorless gas with a pungent odor. It is a chemical compound of boron and chlorine and is highly reactive and corrosive.

Label Information

  • Contents: The canister contains boron trichloride (BCl₃).

  • UN Number: 1741

    • Purpose of UN Number: The United Nations number 1741 is used to identify boron trichloride for transport and emergency response purposes.

  • Hazard Symbols

    • Corrosive Symbol: The label features a corrosive hazard symbol indicating that boron trichloride is highly corrosive and can cause severe burns to skin and eyes.

    • Toxic Symbol: Often, the label will also include a toxic hazard symbol (typically a skull and crossbones) indicating the substance's potential to cause serious health effects upon exposure.

  • Warning Information

    • Respiratory Protection: The label warns users to use proper respiratory protection when handling the gas to avoid inhalation.

    • Handling Instructions: Handle the gas with extreme care due to its corrosive and toxic properties. Use in well-ventilated areas or within controlled environments with appropriate safety equipment.

    • Emergency Procedures: The label may include first aid instructions in case of exposure, such as rinsing with plenty of water if skin or eye contact occurs and seeking immediate medical attention.

Physical and Chemical Properties

  • Appearance: Colourless gas.

  • Odour: Pungent odour.

  • Boiling Point: 12.6°C (54.7°F)

  • Melting Point: -107.3°C (-161.1°F)

  • Density: Heavier than air, with a density of 1.349 g/L at 15°C.

Health Effects

  • Acute Exposure: Inhalation of boron trichloride can cause severe respiratory irritation, coughing, choking, and potentially life-threatening pulmonary edema. Skin and eye contact can cause severe burns and permanent damage.

  • Chronic Exposure: Long-term exposure can lead to chronic respiratory conditions and potential damage to the lungs, skin, and eyes.

Reactivity and Compatibility

  • Water Reaction: Reacts violently with water, releasing hydrogen chloride gas (HCl) and forming boric acid (H₃BO₃). The reaction with water is highly exothermic.

  • Incompatible Materials: Avoid contact with moisture, strong bases, and oxidising agents. Boron trichloride can react with metals, forming flammable hydrogen gas.

Environmental Impact

  • Air and Water: Boron trichloride can cause air and water pollution if released into the environment. It can react with water vapor in the atmosphere, forming corrosive acids that contribute to environmental damage.

  • Ecosystems: The substance is harmful to aquatic life and can cause long-term adverse effects in the aquatic environment.

Safety Measures

  • Storage: Store in a cool, dry, and well-ventilated place away from incompatible substances. Ensure storage areas are equipped with proper ventilation and spill containment systems.

  • Handling: Use appropriate leak detection methods and regularly inspect equipment. Handle with care to prevent leaks and spills. Use in areas with proper ventilation or within fume hoods.

  • Protective Equipment: Use personal protective equipment (PPE) such as respirators, gloves, eye protection, and flame-resistant clothing when handling boron trichloride. Ensure that all personnel are trained in handling corrosive and toxic gases and emergency response procedures.

Regulatory Information

  • Occupational Exposure Limits: Various regulatory bodies have established exposure limits for boron trichloride. These limits are set to protect workers from the harmful effects of the gas.

  • Transport Regulations: When transporting boron trichloride, it must be properly labeled and packaged according to international regulations, such as those set by the International Air Transport Association (IATA) and the International Maritime Organisation (IMO).
