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.
What is 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.
