I. HOW TO READ THESE INSTRUCTIONS /
WHAT THE SYMBOLS MEAN
The purpose of safety symbols is to attract your
attention to possible dangers. The safety symbols,
and the explanations with them, deserve your careful
attention and understanding. The safety warnings do
not by themselves eliminate any danger. The instructions
and warnings are not substitutes for proper accident
prevention measures.
SAFETY ALERT SYMBOL: Indicates warning or caution. It may
be used in conjunction with other symbols or pictographs.
WARNING:
Failure to obey a safety warning may result in
property damage, serious personal injury or death, and the
serious personal injury or death of others. Always follow the
safety precautions to reduce these risks.
CAUTION:
Failure to obey a safety caution may result in property
damage, personal injury, and injury to others. Always follow
the safety precautions to reduce the risk of fi re, other property
damage and personal injury.
NOTE: Advises you of information or instructions vital to the
operation or maintenance of the equipment.
In the following instructions, cautions and warnings, there are
two types of consequences for failure to heed:
A. IMMEDIATE, that may result in personal injury or a failed
operation that may result in a less than optimum bond and that
will not give the physical and electrical performance expected.
B. EVENTUAL, that may result in a later premature rail break,
causing a serious derailment accident with personal injuries or
death, and loss of property.
II. GENERAL RULES FOR SAFETY IN THE APPLICATION
OF EXOTHERMIC HEAD BONDS TO THE RAIL
WARNING:
Do not attempt to make an exothermic bond
until you have thoroughly read and understand the
instructions that accompany all of the various components
of the system and have been properly trained in the use
of this product. Use only the system components designed
to be used together from a single manufacturer. Failure to
comply may result in unsatisfactory bonding as well as accidents
involving fi re, personal injury, and rail damage that may lead to
property damage, injury or death.
WARNING:
Only the correct grinding equipment, welding
equipment, welding material, and bonds designed for the
specifi c application must be used. All items used must be
designed and supplied by the same manufacturer. All items must
be in good condition and not worn, altered or damaged. Failure
to do so may result in an unsafe application with the risk of
personal injury and/or a less than optimum bond.

WARNING:
The area where the bond is to be
applied must be sheltered suffi ciently if the weather is
inclement. This is to keep the rail surface, all equipment, and
materials dry until the weld is completed. Failure to do so may
result in an unsafe application with the risk of personal injury
and a less than optimum bond.
CAUTION::
The work area must be well ventilated.
Workers should avoid breathing the smoke of the exothermic
reaction by positioning themselves upwind of the mold before
igniting the welding material. After ignition, it is advisable to
step back from the mold. Failure to observe this instruction
may result in lung irritation.
WARNING:
The worker(s) performing the welding
must be properly dressed and equipped. Examples include
cotton or woolen garments (most synthetic fabrics melt rather
than char when exposed to fl ame, causing severe burns), safety
footwear with non-slip soles, head protection, leather gloves,
eye goggles and other clothing and equipment recommended
or required by the person’s employer, industry practice, or
applicable laws and regulations. The worker(s) must not be
under the infl uence of any alcohol, drugs or other chemicals
that would impair their judgment or performance of the job.
Failure to observe this may result in serious personal injury.
See Figure 1.
CAUTION:
The worker(s) must be certain that they
can achieve good footing in the area where the weld will
be done. They should be able to step away from the weld
reaction, to be upwind of it. Failure to observe this may result
in personal injury.
