Standard Practice for Selection, Integration, and Verification of Active Vehicle Barrier Safety Devices

Importancia y uso:

4.1 There have been instances in the past in which undesired collisions between authorized vehicles and AVBS have occurred. Properly selected, designed, and installed safety devices that are able to inhibit deployment of active barriers when authorized vehicles are in the hazard detection space, in direct proximity to the barrier, can minimize the likelihood that such accidents occur.

4.2 Unintended barrier/vehicle collisions can be very hazardous, will frequently result in significant damage to property, and can also result in personal injury or death, depending on conditions surrounding an incident.

4.3 It is recognized that some vehicle types may not be reliably detected by an individual detection device and an owner may desire placing AVBS in service even though not all vehicle types may be reliably detected. In such determination of use, an owner shall carefully consider such system performance limitations and safety risks, appropriate alternative controls that will minimize safety hazards, and what risks are able to be accepted before placing equipment into service. This practice is intended to provide the owners, designers, installers, integrators, and equipment providers with information that may be important to such decisions, but it is not intended to determine what risks/hazards are acceptable.

4.4 It is also recognized that there may be particular conditions in which an owner may determine that it is not acceptable to have safety devices installed in AVBS. For example, there may be conditions under which the security risks are determined to be more important to an owner than the possible safety hazards. In such circumstances, the owner shall accept the safety risks and possible consequences that are associated with such a determination that safety devices will not be used.

4.5 If an owner determines that safety devices are not to be used, then it is possible that the owner may choose to implement some alternate means to mitigate or reduce a portion of the safety risks.
