The inlet should be at least 1 meter away from any objects that could potentially influence the
airflow characteristics e.g. trees, vertical surfaces or walls.
Avoid overhead high-voltage cables which may cause electrical interference with the
sampling equipment.
Demolition/construction activities and change to normal transport patterns due to road works
etc. can significantly affect the data. Ensure a record of such events is kept to account for
unexpected peaks in concentration.
3.4 Safety
The intended data capture rate should be considered when positioning the monitor. If data
capture above 90% is essential, the unit should be located in an area which has 24 hour
access available.
The positioning should allow for routine maintenance checks to be performed safely by
personnel.
If using a tripod, ensure the tripod legs are bolted to the ground to prevent the unit from
falling.
Ensure the monitor is in a secure location to avoid vandalism or theft.
