Hospital Signage: NABH Guidelines And Signage List

From entry points to exit routes, the strategic placement of hospital signage boards helps ensure smooth navigation, especially in emergencies.

The National Accreditation Board for Hospitals and Healthcare Providers (NABH) in India includes signage requirements in its hospital accreditation standards (6th edition, effective 1 January 2025), because clear signs support patient safety, accessibility and ease of movement within hospitals.

This guide explains what the NABH standards actually require for signage in hospitals, and separates those requirements from good practice that makes hospital signage clear, concise and effective. We also cover the types of signs a hospital needs, including interior hospital signage, and a signage list you can check your hospital against.

Importance Of NABH Guidelines For Hospital Signage

The NABH is dedicated to maintaining high standards of healthcare in India. Its Facility Management and Safety (FMS) chapter covers hospital infrastructure, including signage.

NABH guidelines for hospital signage help hospitals

• Improve patient safety by reducing confusion.
• Ensure efficient hospital navigation for patients and visitors.
• Provide critical information in emergencies.
• Meet legal and regulatory display requirements.

What NABH Actually Requires For Hospital Signage

The NABH standards do not prescribe sign colours, fonts or materials. They set outcomes: signs must exist where they are needed and must be understood by the people who use them. These are the objective elements in the 6th edition hospital standards that relate to signage and display:

Objective element numbers can change between editions, so check them against the current NABH standards document. Hospitals registered under the Clinical Establishments Act also have a legal display duty: Rule 9(i) of the Clinical Establishments (Central Government) Rules, 2012 requires every clinical establishment to display its rates for each service and facility at a conspicuous place, in the local language as well as English.

Key Elements Of Hospital Signage According To NABH

The core NABH test is simple: signage should be clear, visible and understood by patients, families and the community. In practice that means safety signs, directional indicators and patient information in the languages your patients use.

1. Clarity and Simplicity

One of the primary principles of signage for hospitals is clarity. Whether it’s interior hospital signage or external signs, the text should be visible from a distance and legible for people of all ages.

Best practices for hospital signage clarity include

• Use of large, bold fonts with high contrast (e.g., black text on a white background)
• Minimal use of text to avoid overwhelming the reader
• Clear directional arrows and universally recognized symbols, like a cross for the emergency department

2. Language Requirements

India is a multilingual country, and hospitals cater to patients from various linguistic backgrounds. NABH requires signs to be posted in a manner understood by patients, families and the community, which in practice means bilingual or multilingual hospital signage.

For instance, in a hospital in Tamil Nadu, hospital signage boards should display information in both Tamil and English. This ensures inclusivity and avoids confusion, particularly in high-stress situations such as emergencies.

3. Standardized Colors And Symbols (Good Practice)

NABH does not set a colour code for hospital signage. Using consistent colours across the hospital is still good practice, and for safety signs it helps to follow the international convention set out in ISO 7010 and ISO 3864-1, which most people already recognise:

• Red: Prohibition signs (such as "No Smoking") and fire equipment such as extinguishers and fire alarm call points.
• Green: Safe conditions, such as emergency exits, escape routes and first aid stations.
• Blue: Mandatory actions, such as "Wear a mask" or "Sanitise your hands".
• Yellow: Warnings about a hazard, such as radiation, biohazard or a wet floor.

In India, the Bureau of Indian Standards publishes IS 9457 (Safety Colours, Safety Signs and Accident Prevention Tags, revised in 2025), so check its current text when you specify safety signs. For general wayfinding signs, many hospitals use their own consistent house colour, kept distinct from the safety colours, together with universally accepted symbols such as arrows for directions and icons for restrooms, elevators and exits.

Types Of Hospital Signage

NABH requires both internal and external sign postings, so a hospital needs signs that identify it and its key services from afar as well as signs that guide people inside.

1. External Signage

External signage for hospitals typically includes signs that are placed outside the building to guide patients and visitors from a distance.

Some common types of external hospital signage boards include:

• Hospital Name Boards: Large and legible from a distance, displaying the name and type of hospital (e.g., multi-specialty, general, etc.).
• Departmental Signage: Directional signs that guide vehicles and pedestrians to specific areas such as the emergency entrance, outpatient department (OPD), and parking areas.
• Emergency Signs: Positioned in prominent, well-lit locations, often illuminated at night, to direct patients and ambulances quickly to emergency services.

2. Interior Hospital Signage

Interior hospital signage is placed throughout the hospital and should be clear, consistent and accessible.

Some common types of interior hospital signage include

• Directional Signs: These are placed in corridors and waiting areas to guide patients and visitors to areas such as radiology, laboratories, and wards.
• Room Identification Signs: These include signs for patient rooms, consultation rooms, operation theaters, and more.
• Safety Signs: Emergency exit signs, the displayed exit plan, fire extinguisher signs and radiation warning signs at imaging rooms are needed to meet NABH and fire safety rules. Hand hygiene reminders near wash basins and hand rub points are good practice.
• Information Displays: The list of services the hospital offers, patient rights and responsibilities, and (where the Clinical Establishments Act applies) the rates charged for services.
• Restroom and Accessibility Signs: Clear signage for restrooms, elevators, and accessible routes for people with disabilities.

Material And Durability Of Hospital Signage

Hospital signage boards must be durable enough to withstand environmental conditions, especially external signs. NABH does not specify materials; these are common choices:

1. Acrylic or PVC Sheets: These materials are lightweight, durable, and weather-resistant, making them ideal for external and internal hospital signage.
2. Metal: Commonly used for external signage due to its durability and visibility.
3. Photoluminescent (glow-in-the-dark) materials: Useful for exit and escape route signs so they stay visible during a power failure. Check what your state's fire rules and the fire department require for exit signs and emergency lighting.

Inside clinical areas, choose finishes that can be wiped down with hospital disinfectants. In addition to material selection, hospitals should regularly inspect and maintain their signage to ensure it remains legible and functional.

Special Considerations For NABH-Compliant Hospital Signage

Emergency signage, accessibility, and regulatory compliance are the main factors to consider while planning NABH-compliant hospital signage.

1. Emergency Signage

NABH requires a displayed exit plan for fire and non-fire emergencies. Emergency signs should be placed strategically at the entrance of emergency departments, near lifts and stairs, and along evacuation routes.

These signs must be clear, and exit signs should stay visible during a power failure, either through emergency lighting or photoluminescent material.

2. Accessibility And Inclusive Design

NABH requires facilities for the differently-abled, and those facilities only help if people can find them. Mark ramps, lifts, accessible toilets and wheelchair routes clearly. Braille or tactile signs and audible cues for visually impaired patients are good practice rather than a specific NABH signage requirement.

Inclusive design enhances the usability of hospital facilities for everyone, which supports the patient-centred approach behind NABH accreditation.

3. Regulatory Compliance

In addition to NABH standards, hospitals must comply with national and state regulations. Where the Clinical Establishments (Registration and Regulation) Act, 2010 applies, rates must be displayed in the local language and English. Fire exit signs and escape routes are governed by your state's fire rules and the National Building Code, and local municipal laws may regulate external signboards.

NABH assessors check the hospital's infrastructure during the accreditation assessment, and signage that patients cannot understand, or a missing exit plan, will be noted as a gap.

Role Of Signage In Enhancing Patient Safety And Experience

Clear, compliant signage helps prevent accidents, gets patients to the right department quickly, reduces stress during hospital visits and gives essential safety information in an emergency.

Patients are the best judges of whether your signs work. Asking “Was it easy to find your way?” in discharge or OPD feedback shows where people get lost; LazyMonkey’s patient feedback system for hospitals collects that through QR codes placed around the building.

Hospital Signage Maintenance And Audits

NABH requires facility inspection rounds for safety at least once a month (FMS.1.c), with inspection reports documented and corrective action taken. Include signage in these rounds: damaged, faded or outdated signs confuse patients and can be flagged as a gap during an NABH assessment.

Check both internal and external signs, and update signs whenever a department moves, a service is added or the displayed rates change, so that signage stays compliant with NABH and local regulations.

Conclusion

NABH guidelines for hospital signage set a clear outcome: signs that patients, families and the community understand, with services, patient rights and the emergency exit plan on display.

Whether it’s hospital signage boards for external use or interior hospital signage, meeting these requirements and following good practice on colours, materials and accessibility improves navigation and patient safety.
