Extinguisher Manufacturing Date Locations

When determining the level of service an extinguisher requires, you must find the date of manufacture. These dates are located in various locations depending on the model of extinguisher. 



REDLINE Date Location:
REDLINE hand portable extinguishers will have a date above or below the outlet elbow in which the hose is attached to. The date will be a two digit stamping which indicates the year of manufacture (i.e. 98 = 1998).

REDLINE wheeled units will have a date on the shoulder of the tank shell. The shell will have a stamping with a format of MM/ATSM/YY. The MM will be the month and YY will be the year of manufacture.
