How do I Track & Log Refrigerant Leaks?

Many state departments of public health and environmental protection require that commercial refrigerators contain a leak log. A commercial refrigerator is defined as an appliance containing a refrigerant gas system that exceeds 50 lb. For the purposes of safety and protection, it is imperative that you track and log all leaks and repairs to the gas system.

Instructions

• 1

  Use a log provided by the manufacturer, if one exists, to ensure completeness. Normally, logs include categories such as the following: Pound of Refrigerant Added, Date of Last Refrigerant Addition, Number of Days Between Additions, Repair Date and Calculated Leak Rate. Provide the month, day and year for dates.

  Calculate the leak rate with the following formula. Divide the number of pounds of refrigerant added by the number of pounds of the full charge. Multiply this number by the quotient of 365 divided by the number of days between refrigerant addition. Multiply this number by 100.

• 3

  Record all refrigerant leaks, including accidental releases caused by human error, such as damage to or puncturing of a refrigerant line, service valve or cylinder. Also record any repairs, gas additions and leak tests conducted. Log entries immediately upon completion of the task or inspection. Sign or initial the entry, and have any designated technicians or supervisors present sign or initial as well.

  Store the leak log in a weatherproof container inside the compressor space, so that it is never lost or misplaced. Alternatively, place the log in a plastic cover and attach it to the back of the appliance. Keep a log for each appliance.
