Pigging, the pipeline cleaning process in oil and gas industries is very risky. Pig, a line size plug is propelled in the pipeline to remove the scales and debris. So many fatal accidents happened so far during the removal of pig from the pipeline. Safety is very important than anything. This paper deals about providing a cost effective simple easily adaptable solution to avoid accidents during the removal of pig. A passcode open lock is provided at the closure for safety. The passcode will be generated using a microcontroller reading the safe conditions like position of the valves and pressure in the receiver using proximity and pressure sensors. The passcode will randomly change and will be displayed when the condition is safe. The closure cannot be opened without passcode. Thus we can improve the safety and avoid accidents.
