Presentation Transcript
This Subpart is about ensuring that when people need to have a safe and efficient means of leaving a building or facility under emergency situations, that means will be there and they will have minimal problems finding it and using it.

The entire Subpart E is promulgated from NFPA 101 Life Safety Code.

للتأكد من وجود وسائل هروب آمنة و مخارج للطوارىء كافية لإخراج شاغلى المبنى فى حالات الطوارىء

المرجع لهذه المواصفات هو: NFPA 101 وهى المواصفات الخاصة بإنقاذ الأرواح

29 cfr 1910 35
Means of Egress:

It is a continuous and unobstructed way of exit travel from any point in a building or structure to a public way, and consists of three separate and distinct parts:

1- The way of exit access

2- The Exit,

3- The exit discharge.

مسالك الهروب:

هى مسارات الإنتقال التى يسلكها شاغلو المبنى ولا يوجد بها أية عوائق من أية نقطة بالمبنى إلى الطريق العام وتتكون من ثلاثة أجزاء:

مسار الوصول إلى المخرج

  • Inclined egress components: 60 persons/unit (Including Class B ramps)
exit routes width and capacity
Exit Routes Width and Capacity
  • Capacity is a measure of persons per exit width. To understand capacity, it is important to understand the term exit width.
  • Means of egress shall be measured in exit width units of 22 inches.
  • Fractions of an exit width unit shall be counted as:
    • Zero if the fractional unit is less than 12 inches
    • One-half if the fraction is greater than 12 inches and less than 22 inches.
egress capacity and occupant load
Egress Capacity and Occupant Loadحمل الإشغال
  • When capacity has been determined for each means of egress, the projected occupant load for the means of egress must be calculated.
  • Capacity of means of egress shall be sufficient for occupant load of any space served.
  • Occupant Load is the maximum number of persons that may be in a space at any time.
  • The occupant load in any building thereof shall not be assumed to be less than the number determined by dividing the floor area assigned to that use by the occupant load factor for individual occupancies.
  • Capacity of the exits at a floor can be based on individual floor occupant loads (not additive).
