Request correctionFirst reported 23 Jul 2014•Latest report 27 Aug 2024
What this concern includes
Includes only assertions that directly instantiate the manually reviewed condition ‘Inadequate audible movement-warning systems on vehicles and mobile equipment’ and satisfy this evidence boundary: Three distinct reports directly support absent or inaudible warnings for reversing vehicles or moving crane equipment. Front and rear impact-sensor alarms concern obstacle detection rather than warning nearby people or operators of movement and must be excluded.
Not included
- Excludes visual-only vehicle lighting, signalling and marking deficiencies where no audible warning control is involved.
- Excludes generic vehicle design, driver competence, maintenance or collision risks unless an audible movement-warning deficiency is identified.
- Excludes general public warning signage, product labels and non-vehicle alarms unrelated to vehicle or mobile-equipment movement.
- Excludes failures occurring after an adequate audible warning has been provided, including downstream response or treatment failures.
- Excludes manifestations outside the manually reviewed boundary: Three distinct reports directly support absent or inaudible warnings for reversing vehicles or moving crane equipment. Front and rear impact-sensor alarms concern obstacle detection rather than warning nearby people or operators of movement and must be excluded.

Position
An existing operational warning requirement makes an additional audible warning unnecessary and potentially confusing alongside other crane warnings.
