Synergy can Disposal of Hydrogen (H₂)
Overview
Chemical Formula: H₂
Description: Hydrogen is a colourless, odourless, tasteless, and highly flammable gas. It is the lightest and most abundant element in
the universe, often used in various industrial
applications.
Label Information
Contents: The canister contains hydrogen (H₂).
UN Number: 1049
Purpose of UN Number: The United Nations number 1049 is used to identify hydrogen for transport and emergency response purposes.
Hazard Symbols:
Flammable Gas Symbol: The label features a flammable hazard symbol indicating that hydrogen is highly flammable.
Warning Information:
Explosive Risk: The label warns users about the high flammability and explosive nature of hydrogen gas, especially in the presence of air or oxygen.
Handling Instructions: Handle the gas with extreme care to avoid ignition sources such as open flames, sparks, and static electricity. Ensure proper grounding of equipment.
Emergency Procedures: The label may include first aid instructions in case of exposure, such as moving the affected individual to fresh air and seeking immediate medical attention if inhalation occurs.
Physical and Chemical Properties
Appearance: Colourless gas.
Odour: Odourless.
Boiling Point: -252.87°C (-423.17°F)
Melting Point: -259.14°C (-434.45°F)
Density: Lighter than air, with a density of 0.08988 g/L at 0°C.
Molecular Weight: 2.016 g/mol.
Health Effects
Acute Exposure: Hydrogen itself is non-toxic; however, its primary danger comes from its high flammability and explosive potential.
Asphyxiation: In confined spaces, hydrogen can displace oxygen, posing an asphyxiation risk. Symptoms may include dizziness, headaches, and in severe cases, loss of consciousness or death.
Reactivity and Compatibility
Reactivity: Hydrogen is highly reactive and can form explosive mixtures with air (from 4% to 75% by volume) and other oxidising gases.
Incompatible Materials: Avoid contact with oxidising agents and halogens. Hydrogen can react violently with chlorine, fluorine, and other halogens, forming explosive compounds.
Environmental Impact
Clean Energy: When used as a fuel, hydrogen produces water as a byproduct, making it an environmentally friendly energy source.
Atmospheric Presence: Hydrogen has a minimal direct impact on the environment, but its production and storage must be managed to prevent leaks.
Applications
Industrial Uses: Used in the production of ammonia, refining of petroleum, and as a reducing agent in various metallurgical processes.
Fuel Cells: Hydrogen is used as a fuel in fuel cells to generate electricity with water as the only emission.
Rocket Fuel: Utilised as a high-energy rocket propellant in combination with liquid oxygen.
Safety Measures
Storage: Store in a cool, dry, and well-ventilated place away from incompatible substances. Use specially designed containers and storage systems to handle hydrogen safely.
Handling: Use appropriate leak detection methods and regularly inspect equipment. Ensure proper grounding of equipment to prevent static discharge. Use in areas with proper ventilation to avoid the accumulation of gas.
Protective Equipment: Use personal protective equipment (PPE) such as flame-resistant clothing, gloves, and eye protection when handling hydrogen. Ensure that all personnel are trained in handling flammable gases and emergency response procedures.
Regulatory Information
Occupational Exposure Limits: Various regulatory bodies have established guidelines for safe exposure levels to prevent health risks.
Transport Regulations: When transporting hydrogen, 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).
Hydrogen (H₂) is a highly flammable gas used in various industrial applications, including fuel production and chemical synthesis.
