TAS Part I12 Premises for manufacture or processing of glass reinforced plastics

Introduction to this Part

This Part contains additional requirements for premises used for the manufacture or processing of glass reinforced plastics.

TAS I12D1 Application of Part2019: TAS H114.1

(1) This Part is applicable to every building in which glass reinforced plastics are manufactured or processed.

(2) Premises for manufacture or processing of glass reinforced plastic must—

  1. provide for the safety and comfort or workers; and
  2. be constructed in a manner that will avoid the spread of fire within the building and to other buildings.

TAS I12D2 Separation from other buildings2019: TAS H114.2

A building for the manufacture or processing of glass reinforced plastics must be—

  1. separated from other buildings or parts of an occupancy by means of impervious walls with FRL at least 120/120/120; or
  2. separated from all other buildings by a clear space of not less than 6 m.

TAS I12D3 Rise in storeys2019: TAS H114.3

The building must be of single storey construction.

TAS I12D4 Maximum floor areas2019: TAS H114.4

The floor area of any building or fire-separated section must not exceed the relevant maximum floor area set out in Table TAS I12D4.

Insert TAS table (I12D4) I12D4 as follows:
TAS Table I12D4: Maximum floor area of buildings for manufacture or processing of glass reinforced plastics or isocyanates
Type A building construction Type B building construction Type C building construction
Not sprinklered: 1500 m2 Not sprinklered: 1200 m2 Not sprinklered: 1000 m2
Sprinklered: 6000 m2 Sprinklered: 5000 m2 Sprinklered: 3000 m2

TAS I12D5 Required exits2019: TAS H114.5

(1) Each fire-separated section of a building which is a work place must have at least two exits for escape purposes and the number and location of exits must be such that any point on the floor is not further than 20 m from one of the exits.

(2) Only exits with vertically hinged swinging doors may be considered as exits for the purposes of this clause.

TAS I11D6 Hand laminating and spray depositing2019: TAS H114.6

The walls and floors of areas to be used for hand laminating and spray depositing must be constructed of non-combustible materials.

TAS I12D7 Ventilation2019: TAS H114.7

(1) Mechanical or natural ventilation must be via low-level, exhaust ducting in a wall and a fixed, open, floor-level, fresh-air inlet ducting in the opposite wall such as to ensure a cross flow of the ventilation over the complete working area.

(2) Mechanical ventilation must provide not less than 6 air changes per hour.

(3) The ventilation fan and exhaust ducting must be arranged in such a manner as to—

  1. produce a negative pressure within any exhaust ducting within the work place so that a leak in the ducting will not vent exhaust air back in to the work place; and
  2. vent the exhaust air to the atmosphere so as to prevent recirculation of that exhaust air.

TAS I12D8 Smoke and heat roof vents2019: TAS H114.8

Each fire-separated section must be provided with automatic smoke and heat roof vents.
