RULE 10

Fire Safety Measures

CHAPTER 1

Coverage

This Rule covers the Fire Safety Measure for Buildings, Structures and Facilities, Hazardous Materials and Wastes, Hazardous Operations and Processes and Miscellaneous Hazardous Premises and/or conditions, that by its very nature or relation to life, property and environment poses threat or danger.

CHAPTER 2

Fire Safety in Buildings, Structures and Facilities

DIVISION 1

Scope

A. This Chapter deals with life safety from fire and like emergencies in buildings, structures and facilities. It covers construction, protection and occupancy features to minimize danger to life from fire, smoke, vapor and fumes before buildings are vacated. It also discusses procedures and guidelines in fire drills required for all types of occupancies to prevent panic in times of emergencies. It specifies the number, size, and arrangement of means of egress sufficient to permit prompt and safe escape of occupants from buildings, or structures or facilities in case of fire or other conditions dangerous to life and property.

B. Nothing in this Chapter shall be construed to prohibit a better type of design, building construction, more exits, or otherwise safer conditions than the requirements specified in this Chapter.

DIVISION 2

General Requirements

A. Every building or structure, new or old, designed for human occupancy shall be provided with exits sufficient to permit the fast and safe escape of occupants in case of fire or other emergency. The design of exits and other fire safety construction shall be such that reliance for safety to life in case of fire or other emergency will not depend solely on any single fire safety construction. Additional safeguards shall be provided for life safety in case any single safeguard is ineffective due to some human or mechanical failure.

B. Every building or structure shall be designed, constructed, equipped, maintained and operated to avoid danger to the lives and ensure safety of its occupants from fire, smoke, vapor and fumes, during the period of escape from the building or structure.

C. Every building or structure shall be provided with exits of kind, number, location and capacity appropriate to the individual building or structure, with due regard to the character of the occupancy, the number of persons exposed, the fire protection available and the height and type of construction of the building or structure, to afford all occupants convenient facilities for escape. AacDHE

D. Every exit of buildings or structures shall be arranged and maintained to provide free and unobstructed egress from all parts thereof at all times. No lock or fastening device that would prevent escape from the inside of any building shall be installed except in mental, penal, or correctional institutions where personnel are continually on duty and effective provisions are made to evacuate occupants in case of fire or other emergencies.

E. Every exit shall be clearly visible. The route to the exit shall be conspicuously marked in such a manner that every occupant of a building or structure will readily know the direction of escape. Each route of escape, in its entirety, shall be so arranged or marked that the way to a place of safety outside is unmistakable. Any doorway not constituting an exit shall be marked to minimize its possible confusion as an exit. Likewise, passage constituting a way to reach an exit shall be marked to minimize confusion.

F. All means of egress shall be provided with adequate and reliable illumination.

G. Fire alarm systems or devices shall be provided in every building or structure of such size, arrangement, or occupancy, to provide adequate warning to occupants.

H. Every building or structure, section, or area thereof of such size, occupancy and arrangement such that the reasonable safety of a number of occupants may be endangered by the blocking of any single means of egress due to fire or smoke, shall have at least two means of egress remote from each other, so arranged as to minimize any possibility that both may be blocked by any one fire or other emergency conditions.

I. Every vertical way of exit and other vertical openings between floors of a building shall be suitably enclosed or protected to afford reasonable safety of occupants while using exits and to prevent spread of fire, smoke, or fumes through vertical openings from floor to floor before occupants have entered exits.

J. Required Fire Safety Programs/Measures

1. In addition to the requirements, lessees or occupants of buildings, structures or facilities shall observe all pertinent fire safety measures;

2. All occupants or lessees of buildings, structures or facilities shall organize themselves and develop and implement fire safety programs to include among others, fire prevention in the premises, notification of the BFP on the existence of a fire, evacuation of persons and initial fire fighting. The building owner shall take the initiative of formulating the fire safety program for his building and of organizing the occupants to implement the programs.

3. In buildings, leased to and used by one or several companies or persons, the management of each company or each person shall be responsible for fire safety measures within the leased or occupied areas. The building owner shall be responsible for the common areas in the building such as the means of egress, utilities and building service equipment or systems. acADIT

4. In building structures or facilities, such as condominium and the like, where some units of the building are not yet sold, the provisions of paragraph "J" sub-para "3" above shall apply. When all condominium units have been sold, responsibility for fire safety measures in the common areas such as the means of egress, utilities, building equipment/system and the building as a whole, shall devolve jointly upon all individual unit owners or occupants.

K. Compliance with this Chapter shall not be construed as eliminating or reducing the necessity from complying with the other provisions for safety of persons using a structure under normal occupancy conditions. Also, no provision of the Fire Code of the Philippines and this IRR shall be construed as requiring or permitting any condition that might be hazardous under normal occupancy conditions.

L. Construction and Repair Operations

1. New Construction

a. No building or structure under construction shall be occupied in whole or in part until all required means of egress required for the part to be occupied are completed, inspected and approved for occupancy.

b. Adequate escape facilities shall be maintained at all times in buildings under construction for the use of construction workers. These facilities shall consist of doors, walkways, stairs, ramps, fire escapes, or other arrangements in accordance with the general guidelines of the Fire Code of the Philippines and this IRR in so far as they can reasonably be applied to buildings under construction.

2. Repairs or Alterations

a. Existing buildings may be occupied during repairs or alterations provided that all existing fire protection systems/devices are continuously maintained or, in lieu thereof, other measures are taken to provide equivalent safety.

b. Flammable or explosive substances or equipment necessary for the repair or alteration of a building or structure may be introduced therein while it is occupied, only if the conditions of use and the safeguards therefore provided will not create any additional danger or impair the use of the means of egress.

2. Moderate Hazard

Those which are liable to burn with moderate rapidity or to give off a considerable volume of smoke but from which neither poisonous fumes nor explosions are to be expected in the event of fire.

3. High Hazard

Those which are liable to burn with extreme rapidity or from which poisonous gases or explosions are to be expected in the event of fire.

DIVISION 5

Means of Egress

SECTION 10.2.5.1. Application. —

A. Means of egress for both new and existing buildings shall comply with this Division except as may be modified for individual occupancies by Divisions 8 through 17 of this Chapter.

B. Any change, alteration or addition that would reduce the means of egress below the requirements for new buildings is prohibited.

SECTION 10.2.5.2. General Provisions. —

A. Permissible Exit Components

An exit shall consist of the approved components that are described, regulated, and limited as to use by Sections 10.2.5.3 through 10.2.5.12 of this IRR. Exit components shall be constructed as an integral part of the building or shall be permanently affixed thereto.

B. Protective Enclosure of Exits

1. When an exit is required to be protected by separation from other parts of the building by some requirements of this IRR, the construction of the separation shall meet the following requirements:

All Others	7.6	0.3	5	0.4

 

2. The required capacity of a corridor shall be the occupant load that utilizes the corridor for exit access divided by the required number of exits to which the corridor connects, but the corridor capacity shall be not less than the required capacity of the exit to which the corridor leads.

D. Occupant Load

1. The total capacity of means of egress for any floor, balcony, tier, or other occupied space shall be sufficient for the occupant load thereof. The occupant load in any building or portion thereof shall be the maximum number of persons that may be in the space at any time, as determined by the City/Municipal Fire Marshal having jurisdiction, but shall not be less than the number computed by dividing the floor area assigned to that use by the occupant load factor in accordance with the requirements of Divisions 8 through 17 of this Chapter for individual occupancies.

2. Where exits serve more than one floor, only the occupant load of each floor considered individually need be used in computing the capacity of the exits of that floor; Provided, that exit capacity shall not be decreased in the direction of exit travel. When means of egress from the floor above and below converge at an intermediate floor, the capacity of the means of egress from the point of convergence shall not be less than the sum of the two.

3. When any required egress capacity from a balcony or mezzanine passes through the room below, that required capacity shall be added to the required egress capacity of the room below.

E. Measurement of Means of Egress

1. The width of means of egress shall be measured by clear width starting from the narrowest point of the egress component under consideration, unless otherwise provided in para (2) hereof. HCETDS

2. Projections of not more than one hundred fourteen millimeters (114 mm) at a maximum height of nine hundred sixty five millimeters (965 mm) within the means of egress on each side shall be permitted.

2. Factors to be considered in the storage of common commodities:

a. Method and Height of Stock Piling

i. Bulk storage — consists of piles of loose, free-flowing materials, including powder, granules, pellets, or flakes, and agricultural items. The commodities are typically stored in silos, bins, tanks, or in large piles on the floor.

ii. Solid piling — consists of cartons, boxes, bales, bags, etc., in direct contact with each other. Air spaces or flues exist only where contact is imperfect, or where a pile is close to, but not touching, another pile. Because pallets are not typically used, stacking is done by hand or by lift trucks using side clamps or prongs, which are pried between packages or bales without damaging the product.

iii. Palletized storage — consists of unit loads placed on pallets that are then stacked on top of one another. A pallet load usually takes the form of a cube, with dimensions about one hundred twenty to one hundred fifty centimeters (120 cm to 150 cm) in height, and consists of a single or multiple package(s). The top surface of the pallet load must adequately support other pallet loads so that the commodity would not be crushed or the pile would not become unstable. Due to these considerations, the maximum height of palletized storage shall not exceed nine hundred ten centimeters (910 cm).

iv. Rack storage — is a structural framework in which the commodity is placed usually as a pallet load. The design of rack storage systems maximizes vertical storage capacity. The ceiling height or the vertical reach of material handling equipment limits storage heights. Some rack storage arrangements are over thirty meters (30m) high.

iv.a. Single row racks include racks up to one hundred eighty centimeters (180 cm) wide, separated from other storage by at least one meter (1 m) aisles.

iv.b. Double row racks consist of two single row racks placed back to back with a combined width of up to three hundred seventy centimeters (370 cm) and aisles at least one meter (1 m) wide on each side.

iv.c. Multiple row racks utilize a flow through or drive in configuration. They consist of racks greater than three hundred seventy centimeters (370 cm) wide, or single or double row racks separated by aisles less than one meter (1 m) wide, with overall width exceeding three hundred seventy centimeters (370 cm).
