LPG is a popular and efficient energy source used in homes for cooking. It is imperative that you take good care and use it safely and responsibly. LPG Cylinders are strong and cannot be damaged easily. However leaks can occur from cylinder, valves and pipe connections if not kept in good condition or if considerable care is not taken while replacing them. Safety comes from understanding the behaviour of LPG and keeping it under control. Every uncontrolled release is a hazardous event and should receive urgent attention. As pure LPG is odourless and invisible a distinctive odour is usually added to warn of its presence. Thus even the smallest leak can be detected and can receive appropriate attention. However, as LPG is heavier than air, an underground or low level leak might not be detected immediately.  Always be in full attendance when cooking using LPG. The sauce or liquid in your cooking could overflow and extinguish the burners, causing gas to leak if left unattended.
