B. Personal Protective Equipment
To insure proper protection, it is recommended that standard equipment for handling
compressed gases and refrigerants be used for filling operations. This would include the
use of rubber gloves and eye goggles.
All containers (including high pressure gas cylinders) used in filling operations should be
secured to stationary objects to prevent uncontrolled movement.
It is recommended that persons involved in filling operations refrain from smoking.
NOTE: Consult the Halotron I Material Safety Data Sheet (MSDS) for more safety
information. The “Halotron I Health and Toxicity Summary Bulletin” should also
be consulted for additional information.
FILLING/AGENT RECOVERY PRINICPLES
It is imperative that before performing filling or agent recovery procedures, the following
guidelines are followed:
1. All of the Maintenance Procedures detailed in Amerex P/N 14425 “Owners Service
Manual ” be completed.
2. All extinguisher components and filling equipment components are compatible for
use with Halotron I.
Extinguisher filling/agent recovery should be performed only by trained technicians. Amerex
parts and service equipment should be used in the performance of these procedures. Contact
Amerex Corporation if you have any questions regarding parts, recharging equipment,
hydrostatic testing or need for any specialized tools.
All equipment should be maintained dry and free of moisture. Purging all lines with argon each
time the filling apparatus has been exposed to air will help minimize the amount of moisture that
can gain entry to the system.
The general filling procedure follows three basic steps:
1. Extinguisher evacuation
2. Halotron I filling (liquid transfer)
3. Extinguisher
final pressurization
A. Evacuation Principals
Extinguishers may be evacuated one at a time, or in groups through the use of a manifold
system. Cylinder evacuation prior to filling is strongly recommended for two reasons.
1. To remove moist air from the cylinder, which if present can cause corrosion.
2. To accelerate the filling process by removing some of the back pressure that results
from entrapped air.
The vacuum pump selected should be capable of pulling a minimum vacuum of 27 inches
(686 mm) mercury (at sea level).
