To ensure a well-ventilated workplace general ventilation should be provided that removes stale, contaminated,

or hot and humid air so that occupants do not suffer any ill-health effects. It may be worth considering using

effective natural and/or mechanical general ventilation to provide the fresh air supply.

If the contaminant is of a low toxicity and produced in such low concentrations that it would be impractical and

costly to use Local Exhaust Ventilation (LEV), it may be worth considering using general ventilation as part of

the control strategy. However, if there IS a small number of well-spaced contaminant sources, using LEV may be

more cost effective than general ventilation. There may be instances where intermittent exposure to a substance

exceeds the assigned Occupational Exposure Limit (OEL), for example during welding and paint spraying. In this

case, it may be worth considering using LEV to control exposure.

Natural Ventilation

Reasons for Natural Ventilation

• Temperature and air pressure differences in a building create an upward movement of air or ‘stack’ effect.

• Stack ventilation may be effective enough to carry vapours generated by small-scale hot industrial processes upwards. They can then be removed through the roof via roof ventilators or extraction fans. If cooler air comes in at a low level, it will displace the warm rising contaminated air.

• Occasionally, there can be downward air movement if the air is cold.

• Wind forces are affected by wind speed, wind direction and the shape of the building.

• Cross-ventilation occurs when wind blows air through a room or building which has openings (for example windows) on opposite sides.

• Single-sided ventilation occurs when there are one or more openings (such as a window or a door) on one side only.
