Study Notes
Hazards of Propane Misuse
- Propane can cause asphyxiation, explosion, or fire if misused
- It can displace oxygen in confined spaces, leading to asphyxiation
Physical Properties of Propane
- Boiling point of propane: -42.2°C (-43.6°F)
- Stored as a liquid under pressure in cylinders or tanks
- Expands 270 times when released from a cylinder or tank
Safety Precautions
- Propane is 1.5 times heavier than air
- Can collect in low-lying areas and confined spaces, leading to hazards
- Can cause frostbite or injury if accidentally exposed under high pressure
Industry and Applications
- Propane is a convenient fuel for contractors due to its portability and energy density
- Heating value of propane: 91,500 BTU/ft³
- 1 cubic foot of natural gas converts to 1,025 BTU
Cylinder Handling and Storage
- Cylinders should be stored upright, secured, and away from property lines
- Empty and full cylinders should be stored separately
- Relief valves are set to 375 psig to prevent over-pressurization
- Vapour space at the top of a tank allows for thermal expansion
Transportation and Installation
- Propane cylinders should be transported and stored in a secure, upright position
- Cylinders should be placed on a level surface, away from heat sources and open flames
- Bulk tanks and feed lines should be installed by a qualified technician
Safety Procedures
- In case of an emergency, evacuate the area and report the incident
- If you smell propane in a confined space, evacuate and ventilate the area
- If you come into contact with liquid propane, wash the affected area and seek medical attention
