Condition

Condition Assessment
Observed surface contamination consistent with Class C at time of service.
Contamination type: residual surface-level particulate with minor oil presence.
Embedding within step grooves: light, non-compacted presence within grooves.
Step definition visibility: clearly visible across full width.
Overall condition statement: light contamination, no heavy compaction, no deep embedding, and clear step definition.
Frequency Position
EscaTEQ Method™ recommended operational starting point for this traffic profile: monthly.
Actual site-applied frequency: every 2 weeks.
No observable condition degradation was noted at the time of service.
Final frequency should remain subject to contamination rate, facility profile, OEM guidance, and engineering or maintenance-provider review.
Work Performed
Method: EscaTEQ Method™
Application type: surface-only, low-moisture cleaning applied only to exposed step surfaces.
Operator configuration: Single-operator application using handheld, non-powered equipment under normal operating conditions.
Cleaning sequence definition: one complete rotation of the escalator step band.
Observed Outcome
Reduction in visible surface soil was observed across the step band following application.
Observed condition at the time of service: stable.
No operational disruption was noted within the documented review period.
No condition escalation was observed at the time of service.
Outcome Narrative
Observed condition remained stable at the time of service using low resource input. The site-applied frequency was every 2 weeks, while the EscaTEQ Method™ recommended operational starting point for this traffic profile is monthly. No condition escalation was observed. Preventive surface-cleaning frequency should remain subject to contamination rate, facility profile, OEM guidance, and engineering or maintenance-provider review.
Lessons Learned
- Low resource usage was observed during the applied cleaning sequence.
- Condition stability was observed under the site-applied frequency.
- Preventive surface-cleaning frequency should remain site-specific and subject to engineering or maintenance-provider review.
Observations in this case study are based on internal operational records, site conditions, and photographic evidence for the referenced period. This case study describes site-specific outcomes and should not be interpreted as a universal performance claim.
