1、Designation: E2238 12Standard Guide forEvacuation Route Diagrams1This standard is issued under the fixed designation E2238; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicate
2、s the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This standard is intended to provide minimum guide-lines for the design and placement of evacuation route dia-grams (ERDs) used in buildings. It covers the evacuatio
3、n ofbuilding occupants when directed by emergency responseauthorities in emergencies such as fire, earthquake, and bombthreat.NOTE 1Evacuation from the facility is not appropriate in all emer-gencies. For example, a tornado or a release of hazardous materials mayrequire sheltering within the buildin

This diagram standard is intendedto be used in conjunction with a facility emergency plan and instructionson appropriate actions from building management, or emergency responseauthorities, or both.2.

7、vised automatic sprinkler system and has notless than two accessible rooms or spaces separated from eachother by smoke-resisting partitions; or (2) a space located in apath of travel leading to a public way that is protected from theeffects of fire, either by means of separation from other spacesin

Significance and Use4.1 Evacuation route diagrams are informational signs usedto advise building occupan
12、ts, be they employees, residents,patients, or visitors, of the best route(s) to egress the building,or to temporary shelter from their location. It is a pictorialrepresentation of the building/floor layout showing the closestsuch route from a given point in the building. This standardwill provide gu
13、idelines that can be used to provide uniformityin the development and use of these signs. Consistency indesign and placement of these signs can serve to increasefamiliarity and comprehension as well as reduce confusion,thus improving the ability of occupants to egress from thefacility more easily an

United States14.2 Occupancies where standardization of ERDs would bemost b
18、eneficial include those which frequently have occupantsunfamiliar with the facility, such as hotels, places of assembly,offices, healthcare facilities, and multiple occupancy buildings.5. Format and Content5.1 FormatThe overall format of ERDs should be simple.To be quickly read and understood by tho
19、se unfamiliar with thebuilding layout, ERDs should contain only the informationnecessary for the occupant to become oriented to and locate theegress path(s) from their location. The diagram should show atleast two ways to exit from the locations where the diagram isposted.5.1.1 Area CoveredTo minimi
20、ze confusion, ERDs shouldonly cover the area/floor of the facility that contains the at leasttwo exits, an area of rescue assistance (if applicable), and anarea of refuge (if present). The top of the ERD should displaya title indicating the floor number (see Fig. 1).5.1.2 ColorOptimally, signs shoul
21、d be provided in colorwith graphics to more easily distinguish the routes.5.1.3 Current LocationThe current location should beindicated by a solid red circle at least14 in. in diameter, andlabeled “YOU ARE HERE” in capital letters.5.1.4 ExitsExits should be marked by a rectangle marked“EXIT” in red
22、capital letters with arrows pointing to exits.5.1.5 Temporary ShelterTemporary shelters should bemarked by dashed double red lines, shaded, and labeled“TEMPORARY SHELTER” in capital letters.5.1.6 PathsPaths should not direct building occupantsthrough areas which are not intended for egress, such ass
23、torerooms, hazardous areas, rooms that can be locked, or otherareas as specified by NFPA 101, Life Safety Code.5.1.7 Dead EndsDead ends should be depicted using thickblack line with the label “DEAD END” in capital letters.5.1.8 ElevatorsElevators are often not permitted for use inemergencies (such a
24、s fire or earthquake), and may be recalledto the first floor and become unavailable. For these reasons,elevators should be shown on the diagram, but not indicated aspart of the means of egress.FIG. 1 Sample Evacuation DiagramE2238 1225.1.9 Landmarks and BarriersLandmarks and barriersshould be repres
25、ented by a comparable but simplified graphicand identified by a suitable descriptive label.5.1.10 Major Means of Egress ComponentsComponents,including corridors, doors, stairs, and ramps in egress pathsshould be shown in a simplified form.5.1.11 Assembly PointsWhen evacuation to the buildingexterior
26、 is specified, the ERD should display point(s) ofassembly for building occupants to gather and to be accounted.5.1.12 KeyWhere needed, a key should be provided in thelower right corner of the diagram to more clearly define thesymbols used.5.2 LanguageDepending on the needs of the region andnature of
27、 building occupants expected, sign information mayneed to be multi-lingual.6. Visibility and Readability6.1 Sign and Print SizeThe ERD should be a minimum of812 in. high by 11 in. wide. It is recommended that text followNFPA 170, 11.2.4.6.2 IlluminationThe ERD should be continuously illumi-nated on
28、its face with a minimum of one (1) footcandle (10.8lux). ERDs can be photoluminescent in accordance withSpecification E2072 (with a minimum luminance of 5 milli-candela per square meter after 90 minutes) or UL1994.7. Durability7.1 ERDs should be durable and not subject to deteriorationsuch as fading
29、 and tearing.NOTE 3One cost-effective option is to print ERDs on paper andlaminate.7.2 ERDs should be replaced when, through wear ordamage, they become difficult to read.8. Orientation8.1 ERDs should represent and be oriented to the actualfloor arrangement as viewed by building occupants. Thismeans
30、that the top of the diagram should be oriented in thedirection the reader is facing.9. Placement9.1 LocationsThe frequency and location of ERD place-ment should be determined by the needs of the facility. Largerfacilities of complex design may require more frequent ERDsthan smaller buildings with si
31、mple layouts. Facilities withsubstantial numbers of occupants unfamiliar with the buildingmay also call for more ERDs than those where visitors areinfrequent. Facilities should consider placing ERDs in everyroom, at each exit (if there are multiple room exits), and inlarge open occupancy areas every
32、 50-75 ft.9.2 HeightERDs should be mounted 48-60 in. (152 cm)above the finished floor to the center of the sign.10.
