Brief Codes for LPG Safety in Taiwan

1. Storing LPG storage containers in a basement
2. Without safety signs of No Open Flames or without fire extinguishers
3. Without placing gas leakage alarm devices
4. All compressed gas cylinders (including empty ones) without being secured in an upright position at all times, or not being secured to prevent accidental falling

2. In principle, gas cylinders shall be stored outside. Storing inside of buildings shall be in well-ventilated areas, and avoid low-lying areas, staircases, or areas that allow the contents to settle.

3. The location of using LPG cylinders in parallel shall be inspected monthly, including the following items:

1. Safety signs of No Open Flames
2. Fire extinguishers
3. The location of LPG cylinders
4. Measures to avoid falling
5. Measures to avoid direct sunlight
6. Gas pipes
7. Rubber hoses
8. Gas leakage alarm devices

4. The quantity of LPG stored in special buildings or rooms must not exceed 1000kg.

5. Location of gas leakage alarm devices: For LNG storage, the gas detector placement shall have a distance up to 30cm from the ceiling, and have a minimum distance of 3m away from a gas-fire appliance. For LPG storage, the gas detector placement shall have a distance up to 30cm from the floor, and have a minimum distance of 3m away from a gas-fire appliance.

1. At least two separate exits shall be provided from each boiler room, except that there's no interference from boiler operators having quick retreat.

2. A minimum unobstructed clearance from the top of the boiler to the ceiling, beam, piping, or other objects shall be 1.2 meters, except that there's no interference from the inspection, adjustment, and operation of the valves and other equipment.

3. The vertical boiler or the exterior boiler without any coverings shall have a minimum unobstructed clearance of 45cm from all service sides of the boiler to the wall, piping, or another boiler; moreover, the boiler's combustion chamber with an internal diameter of 500mm maximum, and with 1000mm maximum in length, shall have a minimum unobstructed clearance of 30cm.

4. If the boiler and its metal chimneys or flue pipes are not covered with non-metallic and non-combustible materials with a minimum thickness of 10cm, none of any combustible materials shall be placed within 15cm of the exterior boiler, except for the case that the combustible materials are covered with non-metallic and non-combustible materials.

5. Fuel storage in boiler rooms or boiler installation site, the solid fuels shall be at least 1.2m away from the exterior boiler, and the liquid fuels or fuel gases must be at least 2m away from the exterior boiler. However, by the installation of proper fire barriers or other fire-resistive barriers, the range of clearance between the boiler and the fuels or fuel containers are able to be lower.

Check the following:
Is the valve fully open?
Is there any blockage at the strainer?
Is the feed water check valve functioning?
