main control measures for explosion of gas boilers


Hot Water Pressure Increase in Hot Water Tanks or Boilers

Water is at its highest density at 3.98 °C = 1000 kg/m 3 or 1 g/cm 3. The correct SI unit of density of water is ρ = 1000 kg/m 3. [also FYI, 1 m 3 = 1,000,000 cm 3]; Specific weight of water = 62.4 lb/ft 3 (IU) or 9.81 kN/m 3; Specific weight of seawater = 64 lb/ft 3 (IU) or 10.1 kN/m 3 - must be all that extra salt making it more dense, so we float better in seawater than in fresh water, right?

Gases in cylinders | WorkSafe.qld.gov.au

An uncontrolled release of a flammable gas (e.g. LP gas, hydrogen) may lead to a fire or explosion, particularly in a confined area where potential ignition sources are present. If an uncontrolled release is of a toxic gas (e.g. ammonia or chlorine), workers and other persons may be at risk of a toxic exposure.

Get everyone out of the building or area where you suspect gas is leaking. SHUT OFF THE GAS. Turn off the main gas supply valve on your propane tank, if it is safe to do so. To close the valve, turn it to the right (clockwise). REPORT THE LEAK. From a neighbor's home or other building away from the gas leak, call your propane retailer right away.
