PURE LPG IS COLORLESS AND ODORLESS LPG is as clear as water in liquid form and invisible in vapor form. Pure LPG has no smell. Ethyl mercaptan is added so any leaks can be detected by scent.
SLIDE 15
LPG vapor when released to the atmosphere is heavier than air. LPG vapor will then tend to deposit on the lowest portion in the area.
LPG VAPOR IS HEAVIER THAN AIR

LPG has a calorific value of about 49,500 kilojoules per kilogram. For an 11-kg cylinder, that amounts to heat enough to boil 5 liters
- f water everyday for
346 days. LPG HAS HIGH HEAT CONTENT
SLIDE 23
L
Increase in heat comes with increase in pressure LPG in the liquid phase expands due to any increase in temperature. The liquid inside the tank tries to evaporate, but, since it is trapped inside the confines of the tank, pressure builds up.

ULLAGE
Because of liquid expansion, filling is done only up to 85% capacity. The “free space” is called ULLAGE. Overfilling the tank may result to dangerous hydraulic pressures which may cause the discharge of liquid out of the pressure relief valve, or may even rupture the tank.

LIMITS OF FLAMMABILITY Air-Fuel Mixture TOO RICH TO BURN (11-100%) WILL BURN (2-10%) TOO LEAN TO BURN (0-2%)
SLIDE 32
Air-Gas Flammable Mixture The LFL (Lower Flammable Limit) is around 2% mixture of LPG in air - this means that 1 liter of liquid LPG, when mixed with air will give 12,500 liters of flammable mixture.

EMERGENCY ACTION PROCEDURES Eliminate all sources
- f ignition
- immediately. Do not
switch on/off electrical switches which may cause sparks.
SLIDE 34
Close the main gas valve to stop the flow
- f gas.
EMERGENCY ACTION PROCEDURES
SLIDE 35
Open windows, doors and other
- penings to increase
ventilation. EMERGENCY ACTION PROCEDURES
SLIDE 36
Cover leaking portion with wet cloth and/ or spray water to disperse vapor cloud. EMERGENCY ACTION PROCEDURES
SLIDE 37
EMERGENCY ACTION PROCEDURES If leak is on the cylinder, bring the cylinder to a well ventilated and isolated area.
SLIDE 38
EMERGENCY ACTION PROCEDURES If the escaping vapor catches fire: Shut-off main gas valve as well other valves along the line. If fire is on cylinder, spray on the upper portion of the cylinder to keep it cool.
SLIDE 39
Use soapy water when checking for leaks. SAFETY TIP
SLIDE 40
Use LPG resistant flexible hose SAFETY TIP
SLIDE 41
SAFETY TIP Since LPG vapor is heavier than air, it is therefore unsafe to install LPG tanks on the lowest portion of any structure.
SLIDE 42
SAFETY TIP Do not store cylinder in kitchen cabinets without proper ventilation.
SLIDE 43
SAFETY TIP Keep cylinder upright. Never invert or let lie horizontally
SLIDE 44
Store cylinder away from electrical appliances and other sources of fire/ ignition SAFETY TIP
