Gas is a very efficient and clean fuel and is used in many appliances in homes and industries for heating and other applications. Gas by itself is flammable and therefore a substance that can be potentially dangerous, if it is not properly handled. All installations that use gas must be properly maintained and utilized, and this requires the expertise of a gas engineer to see that this is done.
Gas engineers are persons who are highly skilled and have received the training that is essential to install equipment, commission it, and maintain it so that it works efficiently throughout its life cycle. Besides the theory and practical training that these engineers have to go through to qualify as gas engineers, they are required in most states to also be registered with the authorities, who will test their knowledge on the subject, with special regard to the safety aspects of the use of gas.
One of the obvious dangers of using gas is dealing with the leaks through defective piping or incomplete burning. Both will lead to smell and if this is noticed in excess, it is better to get in touch with your gas engineer. You can also call on the engineer to install equipment that is designed to detect leaks and give visual and audible warnings. Gas normally has no odor, but as a safety measure, petroleum companies who supply gas, introduce an odor emitting compound, like mercaptan, which has a distinctive smell that is easy to detect.
All gas using equipment has burners that are designed to burn the gas completely to produce the maximum heat. This equipment can be for boilers, furnaces and cooking appliances. These burners require to be maintained properly so that all the gas that passes through them is completely burnt. In industries, engineers entrusted with this responsibility will routinely call for shutdowns, and inspect and clean these burners. Burners are specially designed to maintain a gas to air ratio, and this at times can get disturbed if the openings lose their shape or get clogged by soot or other material. Engineers will arrange to clean the burners before re-installing them.
Another vulnerable area for gas use comes from the piping, generally flexible, that connects gas supplies to appliances that use gas. These last mile pipes have to contend with movement and can develop cracks, which will cause the gas to leak. Good engineers will periodically inspect these pipes and advice the user if any change is needed. They will also suggest layouts for new installations, so that safety is ensured, the right materials used, and joints and fittings meet the strict standards necessary for the use of gas.
Safety is a very important aspect in all gas installations and is given a lot of importance by engineers who have the right training. Major installations that use gas have to be certified by various authorities before they are allowed to be started and here is where engineers will play a major role, in order to ensure that all the technical details are scrupulously followed.
