Precautions while using CNG

Compressed natural gas can be used in place of gasoline Diesel fuel and propane/LPG.
41. Certification process
The capabilities and capacities of the type approval institutions are inadequate leading to delays in testing. This should be improved in order to reduce the duration of the whole type approval procedure to reasonable, internationally common timeframes. The type approval procedure including the Information on Technical Specification to be Submitted by Manufacturer used by testing agencies needs to be reviewed in order to delete unnecessary.
42. Nozzles and safety
As of now, type approval certificate has been given to CNG vehicles fitted only with nozzles meeting New Zealand Standards NZS. These are prone to frequent o ring failures an item in nozzles. We are informed that they occur on an average about once every 20 fills. This failure not only interrupts fueling and requires replacement of the oring, it also creates a fire hazard due to the release of a significant amount of high pressure gas.
43. When Leakage is Detected
If, even after taking all the necessary precautions, a leakage is detected in a CNG car, there is no need to panic at all. All the owner driver needs to do is close the CNG cylinder valve to cut the gas supply, open all the doors, roll down all the windows and remember not to start the car in any condition. Later, a trained mechanic can be called to take a look at and repair the faulty system.
44. Check the Spark Plugs Regularly
To prevent any misfirings that tend to result from insufficient spark generated by the spark plugs, it is very important that the spark plugs are checked on a regular basis and replaced with new ones after every 13,000 15,000 kms.Also, the performance of a CNG car can be greatly improved if instead of continuing to use spark plugs meant for a petrol car, users opt for spark plugs specially designed for a CNG vehicle.
45. Gas leak smells like rotten eggs
If a really bad smell happens all of a sudden, get out of the house right away and find a grown up.
46. Dont hang on pipes
The pipes might come loose, letting the gas escape. And remind grown ups to keep the outside meter clear in case of an emergency.
47. Be very careful using a gas stove
Roll up your sleeves, keep towels and hot pads away from the flame, and make sure a grown up is around to help.
48. Savings
Total cost of ownership per unit of energy generated is less than many other competitive fuels.
49. Tank Inspection And Expiration
CNG fuel tanks must be US Dept. of Transportation DOT approved. As the structural integrity of CNG tanks degrade over time, all tanks are required to have an expiration label. Do not continue to use expired cylinders! CNG tanks and fuel systems must also be visually inspected after a motor vehicle accident or fire and at least every 36 months or 36,000 miles, whichever comes first, for damage and deterioration per DOT regulation FMVSS 304. CSA certified inspectors may be located here. Cylinder life cannot be extended. Expired cylinders must be removed from service.
50. Securing Tanks
CNG tanks must be secured to the vehicle body, bed, or frame to withstand a force of eight times the weight in all directions of a fully pressurized container 8x G force impact. Only accept the use of brackets and mounting designs which have been approved by the tank manufacturer. Never accept the use of ratchet straps, aluminum bands, etc. on your vehicle.
