1.4.2 Approed, approal
With the approval of. acceptable to. and meeting the prescribed standards of the authority ha ing jurisdiction.
L4.3 AQIS (Australian Quarantine and Inspection Serice)
Inspects and assesses imports for exotic pests and diseases, and provides certification for a range of exports.
1.4.4 Contaminated
Containing harmful or hazardous concentrations of toxic, noxious, pathogenic. flammable, radioactive, explosive, oxidative. corrosive, irritating or other potentially injurious matter, including dusts.
1.4.5 Corrosi’e
Having the quality of damaging or destroying by direct chemical action. This also includes
the effect of caustic substances.
1.4.6 Cryogenic liquid
[)angcrous goods of Class 2. with a boiling point at atmospheric pressure of below minus 90°C. stored in liquid form at or near atmospheric pressure
1.4.7 Dangerous goods
(Australia) Substances and articles that—
(a) satisfy the UN tests and criteria for determining whether they are dangerous goods:
(b) arc listed in the ADG Code: or
(c) arc determined to be dangerous goods by the competent authority.
(New Zealand) Substances and articles that have properties described in table A of NZS 5433, including packaging and empty containers that have not been cleared after containing dangerous goods.
NOTES:
I UN tests and criteria are specified in the UN Manual of Tests and Criteria and the UN Recommendations on the Transport of Dangerous Goods—Model Regulations.
2 Dangerous goods also include empty receptacles or packages that have contained dangerous goods. unless such receptacles or packages have been decontaminated.
1.4.8 Designated radiation area (DRA)
An area where the occupational exposure of personnel to radiation or radioactive substances is under the supervision of a radiation protection adviser (RPA).
NOTE: This includes the ‘controlled’ and ‘supervised’ areas referred to in publications of the International Commission on Radiological Protection, the International Atomic Energy Agency and the NHMRC.
5.1 GENERAL
The ventilation of laboratories shall comply with applicable building regulations and the additional requirements of this Section. Ventilation shall he provided for the wellbeing of building occupants. to remove airborne contaminants and to ventilate storage rooms in accordance with this Section. Ventilation may be b mechanical and/or natural means.
5.2 VENTILATION FOR OCCUPANTS
Laboratories shall be mechanically or naturally eiitilated in accordance with the requirements of AS 1668.2 and this Standard.
The ventilation systems shall meet or exceed the minimum requirements for air quality as indicated in Clause 5.5.
5.3 NATURAL VENTILATION
Laboratories may be naturally ventilated provided that—
(a) the ventilation systems meet the applicable requirements of AS 1668.2 for natural vent ii at ion;
(b) ventilation openings having an openable area of not less than 10% of the floor area. are provided in each laboratory, located to ensure cross-ventilation to provide adequate air exchange:
(c) laboratory processes and instrumentation do not require temperature and humidity control beyond that achievable by this method:
(d) unfiltered ventilation air will not degrade applicable laboratory processes:
(e) fume cupboards and other devices relying on a uniform face velocity for containment are not exposed to draughts which will degrade their containment or performance:
(f) natural ventilation is not used as a primary method for contaminant dilution or control: and
(g) laboratory ventilation is physically segregated from any adjacent non-laboratory area.
5.4.2 Natural cntilation as back-up
Unless it is incompatible ith functional requirements, each laboratory roorii sith external doors and windows shall have a capacity for natural vcntilation. as a hack-up to mechanical ventilation. The back up capability requires an aggregate area to the exterior of at least 2% of’ the floor area of’ the room.
The backup ventilation requirement does not apply to—
(a) internal and other rooms ithout external doors or windows:
(b) rooms with no significant risk of accidental contamination (e.g. rooms with no hazardous substances);
(c) laboratories designed for phsical containment or other application where uncontrolled openings are undesirable: or
(d) laboratories with back-tip or redundant ventilation systems capable of operating when a primary plant fails and s%hen mains power is interrupled.
NOTE: Laboratories using naural ventilation as the primary ventilation sysem. require much greater openable area (see Clause 5.3).
