Halogenated hydrocarbon solvents can cause an explosion when used
with aluminum components in a pressurized fluid pumping system
(pumps, heaters, filters, valves, spray guns, and tanks). The explosion
could cause serious bodily injury, death, or substantial property damage.
No available stabilizers will prevent this violent reaction from happening.
WARNING: Never use halogenated hydrocarbon solvents to
clean aluminum parts or to flush any system. Cleaning agents,
coatings and paints, or adhesives may contain halogenated hy-
drocarbon solvents. Obtain and read the MSDS for each mate-
rial and solvent being used.
S Use nonhalogenated solvents.
S Contact your solvent supplier to determine whether your existing
materials and solvents contain halogenated hydrocarbons or to obtain
a suitable, nonhalogenated hydrocarbon solvent for cleaning and
flushing your system.
S Refer to Table 1. Check the labels on your solvent containers.
Halogenated hydrocarbon solvents can be recognized if any of the
following elements are listed in the name of the product or or as an
ingredient:
Element Symbol Prefix
Fluorine F “Flouro-”
Chlorine Cl “Chloro-”
Bromine Br “Bromo-”
Iodine I “Iodo-”
If you are now using halogenated hydrocarbon solvents in pressurized
systems with aluminum components, perform the following steps:
S Pump the system empty, shut off the pumps, and relieve the system
pressure.
S Disassemble and inspect the system components. Replace any
damaged or corroded parts.
S Thoroughly clean all noncorroded parts with nonhalogenated
hydrocarbon solvents before reassembling the system.
