Synergy can Disposal of deuterium (D₂).

Overview

Chemical Formula: D₂

Description: Deuterium, also known as heavy hydrogen, is a colourless, odourless gas. It is an isotope of hydrogen with one proton and one neutron, making it twice as heavy as the most common hydrogen isotope.

Label Information

Contents: The canister contains deuterium (D₂).

UN Number: 1957

Purpose of UN Number: The United Nations number 1957 is used to identify deuterium for transport and emergency response purposes.

Hazard Symbols

Flammable Symbol: The label features a flammable hazard symbol indicating that deuterium is highly flammable and can form explosive mixtures with air.

Warning Information

Respiratory Protection: The label warns users to use proper respiratory protection when handling the gas to avoid inhalation in case of accidental release, especially in confined spaces.

Handling Instructions: Handle the gas with care due to its flammable 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 moving to fresh air if inhalation occurs and seeking immediate medical attention.

Physical and Chemical Properties

Appearance: Colourless gas.

Odour: Odourless.

Boiling Point: -249.7°C (-417.5°F)

Melting Point: -254.6°C (-426.3°F)

Density: Lighter than air, with a density of 0.180 g/L at 0°C.

Health Effects

Acute Exposure: Inhalation of deuterium gas in large quantities can displace oxygen in the air and lead to dizziness, headache, suffocation, and unconsciousness. It is generally considered to have low toxicity.

Chronic Exposure: There are no significant chronic health effects associated with deuterium exposure under normal handling conditions. However, prolonged exposure to deuterium in high concentrations may lead to asphyxiation due to oxygen displacement.

Reactivity and Compatibility

Reactivity: Deuterium is relatively unreactive at room temperature but can react with other elements and compounds under specific conditions, similar to hydrogen.

Incompatible Materials: Avoid contact with strong oxidisers and halogens. Deuterium can form explosive mixtures with air and other oxidising gases.

Environmental Impact

Air and Water: Deuterium is not known to cause significant environmental pollution. It is a naturally occurring isotope of hydrogen and does not pose a threat to air or water quality.

Ecosystems: Deuterium is not harmful to aquatic life or terrestrial ecosystems. It is a stable isotope that integrates into the natural hydrogen cycle.

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, and eye protection when handling deuterium. Ensure that all personnel are trained in handling flammable gases and emergency response procedures.

Regulatory Information

Occupational Exposure Limits: Various regulatory bodies have established exposure limits for deuterium. These limits are set to protect workers from the potential asphyxiation risk due to oxygen displacement.

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