What should an engineer do if they detect a refrigerant leak during their shift?

When an engineer detects a refrigerant leak during their shift, the most appropriate action is to take immediate corrective action. This is critical because refrigerant leaks can pose serious health hazards, including exposure to harmful gases and environmental harm. By addressing the situation promptly, the engineer can mitigate risks to personnel and the surrounding area. Immediate corrective actions may involve shutting down the system, isolating the leak, or taking precautionary measures to ensure safety until the leak can be repaired.

While notifying maintenance staff or evacuating the premises may be important steps in managing the leak situation, they should follow after taking immediate action to ensure safety and containment. Ignoring the leak is never an acceptable response, as it could lead to more severe consequences if the situation escalates.
