Chemical Composition: Liquefied Petroleum Gas (LPG) primarily consists of propane (C₃H₈) and butane (C₄H₁₀), along with smaller amounts of other hydrocarbons.
Description: LPG autotank’s are used to store and transport LPG as a fuel for vehicles. They are designed to withstand high pressure and are equipped with safety features to ensure secure handling and usage.

Contents: The tank contains Liquefied Petroleum Gas (LPG), primarily a mixture of propane and butane.
UN Number: 1075
- Purpose of UN Number: The United Nations number 1075 is used to identify LPG for transport and emergency response purposes.
Hazard Symbols:
- Flammable Gas Symbol: Indicates that LPG is highly flammable.
- Warning Information:
  - Respiratory Protection: The label warns users to employ proper respiratory protection when handling LPG to avoid inhalation.
  - Handling Instructions: Handle with care due to the high flammability and pressure of the gas. Ensure proper ventilation and use appropriate safety 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.

Appearance: Colourless gas in its gaseous state; colourless liquid when stored under pressure.
Odor: Typically has an added odourant (such as ethyl mercaptan) for leak detection, which smells like rotten eggs.
Boiling Point: Propane: -42°C (-43.6°F); Butane: -0.5°C (31.1°F)
Density: Heavier than air in its gaseous state; varies depending on the specific mixture.
Molecular Weight: Propane: 44.1 g/mol; Butane: 58.1 g/mol.

Acute Exposure: Inhalation of LPG can cause dizziness, headaches, nausea, and in high concentrations, asphyxiation. Skin contact with the liquid can cause frostbite.
Chronic Exposure: Prolonged exposure to low levels of LPG is not typically harmful, but long-term exposure to high levels may lead to respiratory issues.
Skin and Eye Contact: Liquid LPG can cause severe frostbite due to its extremely low boiling point.

Reactivity: LPG is highly flammable and can form explosive mixtures with air. It should be kept away from sources of ignition.
Incompatible Materials: Avoid contact with strong oxidisers and open flames. LPG can react violently with oxidising agents.

Air Quality: LPG contributes to air pollution if not combusted properly, although it is cleaner than many other fossil fuels.
Spill Risk: In the event of a spill, LPG will vaporise quickly but can displace oxygen in confined spaces, posing an asphyxiation hazard.

Automotive Fuel: Used as an alternative fuel for internal combustion engines in vehicles, known as autogas.
Heating and Cooking: Utilised in residential, commercial, and industrial settings for heating and cooking.
Industrial Uses: Employed as a fuel for forklifts, generators, and other equipment.

Storage: Store in a cool, dry, and well-ventilated place away from sources of ignition. Ensure storage areas are equipped with proper ventilation and leak detection systems.
Handling: Use appropriate leak detection methods and regularly inspect equipment. Handle with care to prevent leaks and ensure proper usage.
Protective Equipment: Use personal protective equipment (PPE) such as gloves, eye protection, and flame-resistant clothing when handling LPG. Ensure that all personnel are trained in handling flammable gases and emergency response procedures.

Occupational Exposure Limits: Various regulatory bodies have established guidelines for safe exposure levels to protect workers from the harmful effects of LPG.
Transport Regulations: When transporting LPG, 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).
