low cost co2 leak testing pdf

Because a small leak may gradually build up an explosive concentration of gas, leaks are very dangerous.In addition to causing fire and explosion hazards, leaks can kill vegetation, including large trees, and may release powerful greenhouse gases to the atmosphere.Robotics is one of the fastest growing engineering fields of today.
