This door does not access <br />apartments whose windows flank it. <br />First arriving firefighters will often base their <br />point of entry on which windows have fire or smoke <br />venting from them. In most cases, entrances that <br />serve any particular window will be readily appar- <br />ent from the outside. If it is not obvious which door <br />to, enter to reach which area, signs or diagrams <br />should be provided outside each entrance door <br />indicating portions of the building accessible from <br />the corresponding door (Figure 2.19). <br />In multi-tenant buildings, such as shopping cen- <br />ters and malls, tenants usually have rear exit doors <br />that firefighters may access. Often these doors look <br />alike, making it hard to correlate a given door with a <br />particular tenant. Labeling rear doors on the outside <br />with the tenant's name, address number and/or suite <br />number, using lettering at least six inches high with <br />a'h inch stroke (thickness of lines in each letter) pre- <br />vents this problem (Figure 2.20). <br />Any door that appears to be functional from the <br />outside, but is unusable for any reason, should <br />have a sign reading "THIS DOOR BLOCKED. " The <br />lettering should be at least six inches high with a'h <br />inch stroke. If these doors are properly marked, <br />firefighters will not waste time trying to gain entry <br />through them. <br />r T <br />~s <br />_ <br />1 <br />* <br />i <br />C*-... <br />I <br />(Fig. 2.20) Rear doors of a shopping center labeled for <br />rapid access: utility room, fire protection equipment <br />room, and individual tenant space. <br />Interior Access <br />Large, unusual, or complex buildings present a <br />challenge to maneuvering and locating specific <br />areas. Directional signs with room/tenant numbers, <br />and graphic directories of tenant/agency layout can <br />assist the public (Figure 2.21). The same diagrams <br />may assist firefighters if they include: stairway and <br />elevator identifiers, fire hose valve locations, fire <br />alarm control panel location, fire alarm annunciator <br />location, fire pump location and other fire protec- <br />tion features. Diagrams should also contain fea- <br />tures to assist unfamiliar users with orientation, <br />such as road names or a compass point. <br />Detailed floor plans showing building layout and <br />fire protection systems can assist the fire service. <br />In buildings with fire command centers, a good <br />location for these plans is in this command center. <br />In other buildings, these plans may be locked inside <br />the fire alarm annunciator panel. <br />22, 0SM <br />Occupational Safety and 138 <br />Health Administration <br />
