Short answer: hospital signage is governed by several separate rule sets, not one. Under the 2010 ADA Standards for Accessible Design, signs that identify permanent rooms and spaces must be tactile with Braille (Section 216.2), while directional and informational signs only need compliant visual characters (Section 216.3). OSHA 29 CFR 1910.145 separately sets colors and wording for workplace hazard signs and tags.
General information on published standards, not legal or compliance advice. Local building codes may add requirements.
Definition and scope
In a hospital, “signage” covers at least three distinct things that are often treated as one: accessibility signs (room identification and directions), workplace hazard signs and tags (for example a biological hazard tag), and exit signs. The ADA rules in Section 216 cover signs. The Standards exempt building directories, menus, seat and row designations in assembly areas, occupant names, building addresses, and company names and logos, and they exempt temporary signs of seven days or less. OSHA 1910.145 applies to the design, application and use of safety signs and symbols in the workplace and excludes plant bulletin boards and safety posters. It is not a patient wayfinding standard. Exit signs are covered in the NFPA 101 Life Safety Code guide and are not repeated here.
Which hospital signs must be tactile
The most common misunderstanding is that every sign needs Braille. The 2010 Standards sort signs by function:
| Sign category | ADA section | What it must comply with |
|---|---|---|
| Permanent room and space identification (room numbers, restrooms, room names) | 216.2 | Tactile characters, Braille and visual characters (703.1, 703.2, 703.5) |
| Directional and informational signs (egress routes, rules of conduct, occupant load) | 216.3 | Visual characters only (703.5) |
| Doors at exit passageways, exit discharge and exit stairways | 216.4.1 | Tactile signs (703.1, 703.2, 703.5) |
| Areas-of-refuge instructions and directional signs to accessible egress | 216.4.2, 216.4.3 | Visual characters (703.5) |
| Directories, addresses, occupant names, logos, temporary signs of 7 days or less | 216.1 exceptions | Exempt from Section 216 |
The Standards’ advisory note explains that designation signs label rooms “not likely to change over time”. Pictograms that only give information, such as no smoking or the International Symbol of Accessibility, need no text descriptors, but a pictogram used as a room designation must carry a text descriptor.
Dimensions and placement checklist for tactile signs
- Raised character height: 5/8 in (16 mm) minimum, 2 in (51 mm) maximum, measured on the uppercase “I” (703.2.5). Where separate raised and visual characters carry the same information, raised height may be 1/2 in (13 mm) minimum.
- Stroke and spacing: stroke thickness of the “I” at most 15 percent of character height (703.2.6); line spacing 135 to 170 percent of raised character height (703.2.8).
- Braille: contracted (Grade 2), with domed or rounded dots, dot base diameter 0.059 to 0.063 in and dot height 0.025 to 0.037 in (703.3, Table 703.3.1). Braille sits below the corresponding text, at least 3/8 in from other tactile characters (703.3.2).
- Mounting height: at least 48 in (1220 mm) to the baseline of the lowest tactile character and at most 60 in (1525 mm) to the baseline of the highest (703.4.1).
- Location at doors: alongside the door on the latch side; on the inactive leaf of double doors with one active leaf; to the right of the right-hand door where both leaves are active. An 18 by 18 in clear floor space, centered on the tactile characters and beyond the arc of any door swing between the closed position and a 45 degree open position, is required (703.4.2).
- Finish and contrast: non-glare characters and background, light-on-dark or dark-on-light (703.5.1); no italic, oblique, script or highly decorative type (703.5.3); width of the “O” 55 to 110 percent of the height of the “I” (703.5.4).
- Visual character height: for signs mounted 40 to 70 in high, 5/8 in minimum at viewing distances under 72 in, plus 1/8 in for each foot of viewing distance above 72 in (Table 703.5.5).
Safety signs under OSHA 1910.145
For hazard signs staff see at work, OSHA 1910.145 distinguishes three common types. Danger signs indicate immediate danger and that special precautions are necessary. Caution signs warn only against potential hazards or unsafe practices. Safety instruction signs give general instructions. Each has a color scheme: danger is red, black and white; caution is a yellow background with a black panel and yellow letters; safety instruction is a white background with a green panel and white letters. Sign wording must be easily read and concise. For accident prevention tags, the signal word must be readable at a minimum distance of 5 ft (1.52 m). Biological hazard tags are used to identify the actual or potential presence of a biological hazard. For laboratory chemical labeling, see the Hazard Communication Standard in the laboratory and the NFPA 704 and GHS labels guide.
Where it matters for labs, clinics and facility decisions
A single wall may carry all three regimes: a tactile room designation (ADA 216.2), a hazard sign at the entrance (OSHA 1910.145) and an exit sign (NFPA 101). Each is checked against its own source, so a sign that satisfies one has not shown it satisfies the others. Environment-of-care walkthroughs are a practical place to check them together; see the environment of care rounds checklist, and for new construction the laboratory architect selection guide.
Common misunderstandings
- “Every sign needs Braille.” Not under Section 216: directional and informational signs need only compliant visual characters, and some items are exempt.
- “ADA and OSHA are the same sign rules.” They are not. ADA signs address access to rooms and routes; OSHA 1910.145 addresses workplace hazards.
- “The federal standards are the only rules.” State and local codes may add requirements; check the codes that apply to your building.
FAQ
What are the hospital signage requirements?
There is no single hospital signage rule. The 2010 ADA Standards (Sections 216 and 703) govern accessible signs, OSHA 1910.145 governs workplace hazard signs and tags, and exit signs fall under NFPA 101.
What are the hospital signage standards for room signs?
Permanent room identification signs must have raised characters 5/8 to 2 in high, contracted Braille, a non-glare finish with contrast, and be mounted with the baseline of the tactile characters between 48 and 60 in above the floor, on the latch side of the door.
Do wayfinding signs need Braille?
Under Section 216.3, directional and informational signs must comply with the visual character requirements of 703.5; tactile and Braille requirements apply to the designation and exit door signs described above.
