Signage & Infection Control: Hygiene-Compliant Materials & Design
Post-pandemic infection prevention and control (IPC) standards demand that every surface in a care home is cleanable and hygienic -- including signage. This guide examines material hygiene properties, cleaning agent compatibility, and how to specify signage that supports rather than undermines your IPC protocols.
Infection prevention and control (IPC) has moved from a background concern to a frontline priority in care homes. Every surface that can harbour pathogens is now scrutinised, and signage is no exception. Signs are touched by residents seeking tactile cues, by staff during cleaning, and by visitors navigating unfamiliar corridors. A sign that cannot be cleaned effectively, or that degrades under repeated disinfection, becomes both an IPC risk and a wayfinding failure. Specifying signage materials that meet IPC standards is now a fundamental procurement consideration.
Material Hygiene Properties#
The ideal signage material for IPC compliance is non-porous, smooth (but not glossy), and chemically resistant to standard healthcare disinfectants. Solid acrylic meets all three criteria. Its non-porous surface prevents moisture absorption and bacterial colonisation. Its smooth finish allows thorough cleaning without surface crevices where pathogens can harbour. And its chemical resistance means it can be cleaned daily with chlorine-based disinfectants, alcohol wipes, or QAC solutions without surface degradation. By contrast, porous materials such as MDF, untreated timber, fabric-covered boards, and some vinyl films absorb moisture and cannot be reliably disinfected.
IPC-compliant signage material requirements:
- Non-porous: zero moisture absorption prevents bacterial and viral harbourage
- Chemical resistant: compatible with chlorine solutions (1,000ppm), 70% IPA, and QAC disinfectants
- Smooth surface: no crevices, grain patterns, or texture traps that impede cleaning (note: raised 3D tactile elements should have smooth surfaces, not rough texture)
- No delamination risk: solid construction that will not separate into layers where moisture can penetrate
- Colour-fast under UV and chemical exposure: cleaning agents should not cause fading or discolouration
- Easy-clean mounting: fixing methods that allow the sign to be cleaned around and behind
Cleaning Protocols for Signage#
Signs in clinical and high-touch areas should be included in the facility's cleaning schedule at the same frequency as other environmental surfaces. In bedrooms and corridors, daily wiping with a disinfectant-dampened cloth is sufficient. In bathrooms, kitchens, and clinical rooms, signs should be cleaned twice daily or after any contamination event. Staff should be trained to clean the sign face, edges, and mounting bracket, paying attention to the gap between the sign and the wall where moisture and debris can accumulate.
Pro Tip
During norovirus or influenza outbreaks, increase sign cleaning to the enhanced frequency specified in your outbreak management plan. Signs in outbreak-affected areas should be treated as high-touch surfaces and cleaned with the appropriate outbreak-specific disinfectant.
CQC inspection Key Line of Enquiry S5 (How well are people protected by the prevention and control of infection?) includes assessment of environmental cleanliness. Signs that appear dirty, damaged, or visibly contaminated will be noted as evidence of inadequate IPC practice.
Recommended Products
Our 5mm solid white acrylic signs are IPC-compliant by design. The non-porous surface is compatible with all standard NHS-approved disinfectants and can be cleaned daily without degradation. The smooth, sealed edges prevent moisture ingress.
IPC-compliant signage is not a separate product category -- it is a baseline specification that all care home signage should meet. By choosing non-porous, chemically resistant materials and integrating signs into cleaning schedules, care homes ensure their wayfinding systems support rather than compromise infection control.
