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, settle and accumulate at lower levels. High concentrations can cause **suffocation and cardiac stimulation**, and when exposed to high temperatures, they decompose into toxic fumes. Most Freon gases are non-flammable themselves, but in confined spaces, excessive concentrations can displace oxygen and cause suffocation. They are divided into two main categories: **fixed industrial alarm systems** and **portable leak detectors**.
