It defines a clockwise numbering sequence starting with the main entrance as number one, identifies standard location conventions for responders (Side A), and specifies code-aligned requirements for visibility and contrast. Recommendations include retroreflective numbering for low-light or smoky conditions, size rules based on distance, and special schemes for courtyards, roof hatches, roll-up doors, and mobile classrooms.","[CenterForSafeSchools.org](CenterForSafeSchools.org)  \nModel Door and Window Classroom Numbering  \nCenter for Safe Schools (CSS), an initiative of Center for Schools and Communities, is a nonprofit organization committed to supporting schools, educators, parents, law enforcement, community partners and local agencies develop and practice emergency management and crisis response plans, create positive school environments, implement evidence-based programs, and establish proactive safety measures.  \nPurpose of Numbering School Doors  \nWhen emergencies occur, the rapid response of emergency workers to the incident can be critical. Many schools have dozens of doors providing entrance and egress to their buildings. During an emergency, it may be necessary for responders to gain access through the door closest to the emergency scene. Numbering external doors can be extremely valuable to emergency responders and will also assist your students and staff in acclimating themselves to door locations in case of an emergency.  \nNumbering Sequence  \nAll exterior doors should be numbered in a sequential order starting with the main entrance (office door and public entrance). The main entrance should always be designated as number one. Subsequent doors will be numbered in sequential order in a clockwise manner.  \nResponders typically identify the front of the school as “Side A.”  \nCenter for Safe Schools is here to help.  \nContact us for technical assistance on interior and exterior door numbering.  \nEmail us at Info@CenterForSafeSchools.org or call us at 717-763-1661.  \nExterior Numbers  \nAccording to Section 505 of the International Fire Code requirements (§ 505), all numbers should be:  \n• Arabic numbers.  \n• Visible from the street or closest traffic way and driveway.  \n• Contrasting with their background.  \n• Retroreflective for low light or smoky conditions.  \nAdditional Recommendation  \nUtilizing retroreflective material can assist emergency responders during nighttime, low light or smoky conditions.  \nNOTE: In most cases, white numbers work well on clear glass. While a bulk purchase of one color may be economical, it may be less useful on some surfaces or require a back panel.  \nExterior Number Position  \nAll numbers should be:  \n• Placed at the top right of the door.  \n• Where a multiple bank of doors (three or more) is present, it is good practice to center the number or put the same number at both ends of the bank.  \n• Each door may be numbered separately, as follows: 3-1, 3-2, etc.  \n• Some schools have chosen to mark each door with an  \nindividual number when they face different directions (north and east).  \nExterior Number Sizing  \nAccording to the International Fire Code § 505 requirements, all numbers should be the correct size in correlation with how far from the street or fire department access (Ord. 2010-17 § 1 (part), 2010; Ord. 2007-15 § 1, 2007):  \n• Structures up to 36 feet away: numbers are a minimum of  \n4 inches high and a minimum of 1/2-inch stroke width.  \n• If the structure is 36 to 50 feet away: numbers are a minimum of 6 inches high and a minimum of 1/2-inch stroke width.  \n• When the structure is more than 50 feet away: numbers are a minimum of 9 inches high and a minimum of 1-inch stroke width.  \nSome schools have chosen to use 12-inch numbers for increased visibility. Obviously the larger the number, the greater the distance it will be visible to responders.  \nExterior door with number on door  \nExterior door with number on building  \nInterior Numbers  \nThe numbers should:  \n• Match the number on the outside of the door.  \n• Always be placed on the hinge side of the door near the bottom so they can be viewed in smoky conditions.  \n• Contrast with their background.  \n• Be retroreflective for low light or smoky conditions.  \nCourtyard Doors  \n• Completely enclosed courtyards are numbered C-1, C-2, etc., and are numbered on both the inside and outside, in the same manner as other exterior doors.  \n• Generally, ","cbCaio0hrGvcJTNV","https://ap.wps.com/l/cbCaio0hrGvcJTNV","pdf",1041219,1,4,"English","en",105,"# Purpose of Numbering School Doors\n## Numbering Sequence\n# Exterior Numbers\n## Exterior Number Position\n## Exterior Number Sizing\n## Courtyard Doors\n# Interior Numbers\n# Roof Hatches and Roof Access Doors\n# Roll-Up (garage-style) Doors\n# Mobile Classrooms","[{\"question\":\"How should exterior school doors be numbered during emergencies?\",\"answer\":\"Exterior doors should be numbered sequentially starting with the main entrance as number one, then continued in a clockwise order.
