Tas Part H114 Premises for manufacture or processing of glass reinforced plastics

Tas H114.1 Application of Part

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

Premises for manufacture or processing of glass reinforced plastic must—

(a)

provide for the safety and comfort of workers; and

(b)

be constructed in a manner that will avoid the spread of fire within the building and to other buildings.

Tas H114.2 Separation from other buildings

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

(a)

separated from other buildings or parts of an occupancy by means of impervious walls with FRL at least 120/120/120; or

(b)

separated from all other buildings by a clear space of not less than 6 m.

Tas H114.3 Rise in storeys

The building must be of single storey construction.

Tas H114.4 Maximum floor areas

The floor area of any building or fire-separated section must not exceed the relevant maximum floor area set out in Tas Table H114.4.

Tas H114.5 Required exits

(a)

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 the exits must be such that any point on the floor is not further than 20 m from one of the exits.

(b)

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

Tas H114.6 Hand laminating and spray depositing

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

Tas H114.7 Ventilation

(a)

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 air over the complete working area.

(b)

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

(c)

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

(i)

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 to the work place; and

(ii)

vent the exhaust air to the atmosphere so as to prevent recirculation of that exhaust air.

Tas H114.8 Smoke and heat roof vents

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