Mechanized Gate Malfunction Leads to Severe Injury
A mechanized gate injury prompts expert review on causation and industry compliance, raising questions about safety standards and liability.
Updated on
Case Overview
This case involves an individual who sustained injuries from a mechanized heavy steel gate. The gate, approximately 20 feet wide, was activated by the plaintiff when they pressed a button for access. Allegedly, the gate rolled out, fell forward, and struck them, leading to significant injuries. An expert in gate installation has been consulted to evaluate the situation, focusing on the possible causation and compliance with industry standards regarding mechanized gates.
Questions to the Construction expert and their responses
What industry standards exist, if any, to ensure a mechanized gate is installed and functioning properly?
It appears they didn’t put positive stops on this gate. An automatic gate that rolls out and falls on someone is in violation of every code in the gate industry. The building code requires that you comply with the ASTM code, and the ASTM code requires compliance with the UL codes. A gate that falls on someone is inadequate and is not meeting codes, guidelines, or industry practices.
Please describe your experience in gate installation, specifically as it pertains to larger mechanized gates, if applicable.
I have extensive experience in the door, gate, and dock industry. Additionally, I am a licensed gate and door contractor in six states.
