and maintenance procedures. Therefore, each person involved in installing or maintaining the guard rail
system should read and understand every instruction BEFOREHAND. Users should have access to the
manual at all times and should routinely review the directions.
This manual uses SIGNAL WORDS to classify personal injury risks and situations that might lead to property
damage, as well as to draw attention to safety message(s). The reader must understand that each signal word
indicates the seriousness of the identified hazard.
Identifies a hazardous situation which, if not avoided, WILL result in DEATH or
SERIOUS INJURY. Use of this signal word is limited to the most extreme situations.
Identifies a hazardous situation which, if not avoided, COULD result in DEATH or
SERIOUS INJURY.
Indicates a hazardous situation which, if not avoided, COULD result in MINOR or
MODERATE injury.
Identifies practices likely to result in product/property damage, such as assembly,
installation, etc. that might unnecessarily damage the guard rail.
Employers are responsible for training employees to use the product properly. If you do not understand an
instruction, ask your supervisor or employer for assistance, because failure to follow the directions in this
manual might result in serious personal injury or even death. The Manufacturer is not liable for any injury or
property damage that occurs as a consequence of failing to apply either: 1) the instructions in this manual;

Safety Considerations
This guard rail system is designed for installation on private property, including private roadways.
Standard units do not provide the level of performance recommended by the U.S. Dept. of Transportation (DOT),
that is, they are NOT designed for installation on public roadways. DOT compliant posts are available as special
orders.
Improper or incomplete installation constitutes misuse of the guard rail system. Securely anchor each post to
the supporting surface, e.g. concrete or asphalt, and securely fasten each rail section to 2 posts as described in
this manual.
Replace any component of this system after it sustains impact damage.
