Lateral Instability
Lateral instability is when the floor system becomes loose and unstable. There are gaps between panels. Panels shift laterally when weight is applied.
- Missing edge trim
- Lateral braces loose or untied
- User abuse
- Incorrect cutouts
- Leaving panels out
- Poor installation
- Drastic temperature changes
- Multi-phased installations
Causes:
- Structural damage to other floor components
- Equipment subject to shifting
- Personnel hazard
- Allows debris to drop on stringers causing vertical instability
- Reduction in plenum pressure from air conditioning
- Allows water/chemicals used in cleaning to corrode understructure
- Safety hazard
Consequences:
