Freon Gas Alarm (Refrigerant Leak Alarm)
# Freon Gas Alarm (Refrigerant Leak Alarm) Freon (refrigerant R22/R134a/R410A/R404A, etc.) alarms are used to detect refrigerant leaks in refrigeration systems; most Freon gases are heavier than air, and after leaking, they sink and accumulate. High concentrations can cause **suffocation and cardiac irritation, and decompose into toxic fumes at high temperatures**. They are mostly non-flammable themselves, but in enclosed spaces, excessive concentrations can displace oxygen and cause suffocation. They are divided into two main categories: **fixed industrial alarm systems** and **portable leak detectors**
