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 p ictographs.
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 fire, 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 connection 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 WELDS TO
FOOT OF CONTINUOUSLY SUPPORTED RAIL AND
NON-LOAD BEARING RAIL.
WARNING:
Do not attempt to make an exothermic
connection 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 an
unsatisfactory connection as well as accidents involving fire,
personal injury, and rail damage that may lead to property
damage, injury or death.
WARNING: The location of the connection is very
important! Connections to the foot of the rail steel must only
be made where the rail is continuously supported or on rail
that is non-load bearing in its use. Failure to observe this may
result in rail break leading to property damage, injury or death
to others. See Figure 1.
WARNING: Exothermic connections must not be
made to special alloy track components, such as those
containing high manganese or chromium, without the
prior approval of a qualified expert knowledgeable in
rail applications. When determining whether to approve an
exothermic weld to a special alloy track connection, the
qualified expert will want to consider the following: the
chemistry and microstructure of the component material,
compatibility with copper weld alloy, heat input, cooling rate
and location of the connection prior to making an exothermic
connection. Failure to comply may result in rail break leading
to property damage, injury or death to others.
WARNING: Only ERICO approved grinding equipment,
welding equipment, welding material, and cable size
designed for the specific 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 connection.
WARNING: The area where the connection is to be
applied must be sheltered sufficiently if the weather is
inclement during installation. 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
connection.
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.
