The City of Tampere has begun
the removal of street sand from the city centre. Tampereen
Infra transfers its winter maintenance fleet to sand removal operations in a
controlled manner according to weather and conditions. In
order to control the amount of street dust, the removal is done as quickly as
possible, but a cold snap in spring can slow down the work. Some
property companies have also begun to remove sand from the pavements.
Tampereen Infra began removing the sand on
Tuesday 27 March 2012 from the main arteries and bus stops of the city centre
and near the city offices, Koskipuisto, Hämeenpuisto, the Railway Station,
Pyynikintori and Metso as well as around the bus station. If necessary, the sand being swept away is dampened with a calcium
chloride solution. According to the ten-day weather forecast,
the temperature at night will continue to drop below zero at times. Night time frosts make it more difficult to collect road sand in the
morning. The removal of road sand will begin in
full force with the whole fleet on 10 April. At this time, the sand will be
removed in two shifts. The goal is to have all of the sand
removed by Mayday, weather permitting.
The responsibility for removing road sand
corresponds to winter maintenance duties: The remaining
sand is removed by the party that carried out the sanding. The city
removes the sand from roadways, city squares and light transport routes. Property owners, or in practice maintenance companies, landlords or
building owners remove the sand from the pavements adjacent to their
properties. If the property is owned by the city, the
city cleans the adjacent pavements.
The sand must be removed while damp. Using
a leaf-blower is prohibited.
The sand must be removed while wet in
order to prevent it from becoming dusty. Therefore, rainy weather is a
favourable time for cleaning. In order to
control the road dust problem, the sand must be removed quickly, provided the
conditions permit it. The environmental protection instructions
of the City of Tampere has expressly prohibited the use of leaf-blowers for
cleaning sand. The sand may not be swept into storm
drains as this clogs up the drainage system. Instead it must be brought to a
soil reception station.
Street dust season ahead?
On Tuesday 27 March and Wednesday 28
March, the air quality in Tampere was at times passable or poor, but so far the
amount of respirable (PM10) particles has exceeded the daily limit
only once, on 6 March 2012, at the Pirkankatu and Epilä measurement stations. Rains which may occur help to ease the dust problem.
You can monitor the air quality in the
City of Tampere in real-time using the national air quality portal at
www.ilmanlaatu.fi. When the limit values for dust content or
nitrogen dioxide have been exceeded, separate notifications are provided at
www.tampere.fi/ymparistojaluonto/ilmanlaatutiedotus. Dust content limits are exceeded most easily in dry weather.
Hourly and daily limit values have been
determined for air pollutants, and when these are exceeded the population must
be notified. The limit value level for respirable (PM10)
particles is exceeded if there is an average of over 50 micrograms of particles
in one cubic metre of air throughout the day. The values can be exceeded 35 times at each measurement station over the
course of a calendar year before the limit is considered to be exceeded. Children, elderly people and people suffering from respiratory and heart
diseases are sensitive to the health issues caused by the particles. A high concentration of particles can lead to such problems as a stuffy
nose, coughing and irritated eyes, an increase in asthma attacks, weakened lung
function and an increase in respiratory infections.
Air quality is measured in Tampere at two
fixed and two mobile air quality measurement stations. The fixed
stations are located on the side of Pirkankatu and at the bus stop, and the
mobile stations are currently located in Epilä and Kaleva.

You can monitor the air quality of several Finnish towns using the national air quality portal www.ilmanlaatu.fi.
