(c) Floor Construction — The floor shall be constructed of

incombustible material.

(d)

Interior

Surface .—

Paint

spray

booths

shall

be

designed to permit the free passage of the exhaust air

from all parts of the interior and all interior surface shall

be smooth and continuous without outstanding edges.

SECTION 1702. Fire Protection . — Every spray booth

having an open front elevation larger than 1.00 square

meter and which is not equipped with doors, shall have a

curtain

or

metal

deflector

less

than

100

millimeters deep installed at the upper outer edge of the

booth opening.

SECTION 1703. Light . — Paint spray booths shall be

illuminated

through

hammered wire or heat-treated

glass panels. The glass panels shall be located in such a

manner as to reduce the hazard of ignition caused by

paint spray deposit.

SECTION 1704. Ventilation . — (a) General — Mechanical

ventilation shall be provided direct to the exterior of the

building.

The

mechanical

exhaust

system

shall

be

designed to move the air through any portion of the paint

spray area at the rate of not less than 30.00 lineal meters

per

minute.

The

blades

of

exhaust

fans

shall

be

constructed

of

non-ferrous

material

and

shall

be

mounted in such a manner as to prevent contact with the

exhaust duct. The motor shall not be mounted in the

spray booth or the duct system and belts shall be

enclosed where they enter the booth or duct system.

(b) Exhaust Ducts . — Exhaust ducts shall be constructed

of steel having a thickness not less than the values set by

the Secretary. The discharge point for ducts in a paint

spray booth shall be not less than 2.00 meters from the

adjoining combustible construction nor less than 8.00

meters from adjoining exterior wall openings: Except ,

that

the

discharge

point

for

exhaust

ducts

is

not

regulated in a waterwash spray booth.

CHAPTER 18 Glass and Glazing

SECTION 1801. General Requirements —(a) This Chapter

shall apply to exterior glass and glazing in all Occupancies

except Groups A, B, and J Occupancies not over three

storeys in height, and to interior and exterior glass and

glazing in all occupancies subject to human impact as

specified in this Code.

(b) Standards for materials shall conform to the provisions

set by the Secretary on glass dimensional tolerances,

breaking stress levels, and design safety factors.

(c)

Each

light

shall

bear

the

manufacturer's

label

designating the type and thickness of glass. Each light

with

special

performance

characteristics

such

as

laminated,

heat

strengthened

fully

tempered

or

insulated, shall bear the manufacturer's identification

showing the special characteristics and thickness by

etching or other permanent identification that shall be

visible after the glass is glazed.

SECTION 1802. Area Limitation . — Exterior glass and

glazing shall be capable of safely withstanding the load

due to wind pressures for various height zones above

ground acting inward or outward. The area of individual

lights shall not be more than the maximum allowable

area of glass according to the wind load multiplied by the

appropriate adjustment factor.

SECTION 1803. Glazing . — Glass firmly supported on all

four edges shall be glazed with minimum laps and edge

clearances in accordance with Section 1801 paragraph (b),

Provided, that glass edge clearance in fixed openings

shall be not less than what is required for wind and

earthquake drift. For glass not firmly supported on all four

edges and design shall be submitted for approval of the

Building Official. Glass supports shall be considered firm

when deflection of the support at design load does not

exceed 1/175 of the span.

SECTION

1804. Louvered Windows . — Regular plate,

sheet,

or

patterned

glass

in

jalousies

and louvered

windows

shall

not

be

thinner

than

5.6

millimeters

minimal and not longer than 1.20 meters. Exposed glass

edges shall be smooth.

SECTION 1805. Impact . — Frameless glass doors, glass in

doors, fixed glass panels, and similar glazed openings

which may be subject to accidental human impact shall

conform with the requirements set forth by the Secretary

on impact loads of glass: Except in the following cases:

(1) Bathtub and shower enclosures shall be constructed

from approved shatter-resistant materials, such as: wire

reinforced glass not less than 5.6 millimeters thick; fully

tempered glass not less than 4.8 millimeters thick: or

laminated safety glass not less than 6.4 millimeters thick.

(2) Glass lights located not less than 450 millimeters

above the adjacent finished floor or walking surface.

(3) Glass lights when the least dimension is not greater

than 450 millimeters.

(4) Glass lights 1.50 square meters or less in area.

CHAPTER 19 The Use of Computers

SECTION 1901. General Rule . — The use of computers for

all or any part of the design of buildings under this Code

is permitted provided that all programs to be used are

documented.

SECTION

1902.

Program

Documentation .

—

Documenting a program under this Code consists of

filing

with

the

Building

Official

a

reference

to

a

publication or publications accessible to him were the

detailed description of the program or a brief statement

of the theoretical background of the program including a

description of the algorithms used are found.

SECTION

1903.

Submission

of

Computer-Generated

Computations .

—

A

copy

of

the

output

sheets for

computer-generated computations shall be submitted as

a part of the design computations. The out sheets shall
