|New Standard for Automated Gates |
Picture a heavy metal gate in the driveway of an institution. A guard opens the gate with an electric switch, reaches through the bars to move a chain, and gets trapped as the automation forces the bars against his arm.
ASTM Committee F14 on Fences hopes to reduce this type of accident with better design and performance prescribed in F 2200, Standard Specification for Automated Vehicular Gate Construction. Installers who follow the standard can expect to reduce potentially dangerous gaps in automated vehicular gates and improve the use of hardware particularly in the area of roller covers, says Joseph R. Hetzel, P.E., technical director, Door and Access Systems Manufacturers Association (DASMA), Cleveland, Ohio.
Hot off the press last month, the standard covers materials, installation, and some operational functions of automated gates for vehicular traffic, including:
Horizontal slide or swing gates;
Vertical lift or pivot gates; and
Overhead pivot gates.
"Were trying to reduce the risk associated with people getting caught in some type of moving part, says Hetzel.
Concern over entrapment and pinch points prompted members of three trade associations to draft a document and present it to ASTM International for ballot. DASMA, the American Fence Association (AFA), and the National Ornamental and Miscellaneous Metals Association (NOMMA) collaborated on the draft for approximately three years, according to Hetzel.
This document had a broader exposure than a normal committee ballot because each of the three associations continued to participate during the ASTM development process, notes Tom OToole, ASTM technical committee manager.
Hetzel, who drafted the standard with installers, manufacturers, and consultants, concludes, For installations that conform to the standard, we anticipate there will be a significant improvement in safety for the user and, consequently from that, there should be a significant reduction in liability exposure for both the gate installer and the property owner.
