ventilation system

Voorbeeldzinnen

1. .2 the duct is used only at the terminal end of the ventilation system; and
2. The ventilation system should be so designed as to avoid harmful draughts and noise disturbance.
3. After installation the system shall be tested under varying conditions of engine operation and ventilation.
4. It may be necessary to provide a ventilation system having the capacity both to heat and cool the air supplied.
5. The ventilation system must be capable of ensuring even distribution throughout with a minimum airflow of nominal capacity of 60 m3/h/KN of payload.
6. .1 There shall be provided an effective power ventilation system for the special category spaces sufficient to give at least 10 air changes per hour. The system for such spaces shall be entirely separated from other ventilation systems and shall be operating at all times when vehicles are in such spaces.
7. .5 Stairway enclosures shall be ventilated and shall be served only by an independent fan and duct system which shall not serve any other spaces in the ventilation system.
8. Absence, non-compliance or substantial deterioration of fire detection system, fire alarms, firefighting equipment, fixed fire-extinguishing installation, ventilation valves, fire dampers, quick-closing devices to the extent that they cannot comply with their intended use.
9. .4 Arrangements shall be provided to permit a rapid shutdown and effective closure of the ventilation system in case of fire, taking into account the weather and sea conditions.
10. The purpose of the ventilation system is to provide sufficient fresh air of an appropriate quality and to keep down the levels and spread of odours, noxious gases, dust and infectious agents of any kind.
11. evacuation of carcinogens or mutagens at source, local extraction system or general ventilation, all such methods to be appropriate and compatible with the need to protect public health and the environment;
12. Locations in the vicinity of deck girders and ventilation shafts or other locations where air currents could adversely affect system operation and locations where impacts or mechanical damage are likely shall be avoided.
13. Decisions on frequency of cleaning should be based on the type of animal enclosure, the type of animal, the stocking density, and the ability of the ventilation system to maintain suitable air quality.
14. Where an artificial ventilation system is used, provision must be made for an appropriate back-up system to guarantee sufficient air renewal to preserve the health and well-being of the calves in the event of failure of the system, and an alarm system must be provided to warn the stock-keeper of the breakdown.
15. The number of air changes shall be increased at least to 20 during loading and unloading of vehicles. Ventilation ducts serving special category spaces capable of being effectively sealed shall be separated for each such space. The system shall be capable of being controlled from a position outside such spaces. .2 The ventilation shall be such as to prevent air stratification and the formation of air pockets.
