Contact Status Scientific Controls for further details regarding the cross-sensitivity of a particular
sensor.
5.6 Sensor Disposal
All gas sensors should be disposed of according to local waste management requirements and
environmental legislation. They should not be burnt since they may evolve toxic fumes. Status
Scientific will accept sensors for disposal (by prior arrangement) contact Status Scientific Controls
for further details.
5.6.1 Oxygen Sensors
Oxygen Sensors contain a 4-molar potassium acetate solution which is corrosive. They also
contain small amounts of lead, lead oxide, platinum, silver, carbon and antimony, some of which
are toxic and/or mutagenic. As these sensors contain some highly toxic compounds, irrespective
of physical condition, they should be disposed of according to local waste management
requirements and environmental legislation. They should not be burned as they may evolve toxic
fumes.
5.6.2 Toxic Gas Sensors
The majority of toxic gas sensors contain a sulphuric acid electrolyte. They also contain platinum,
ruthenium, gold, silver and carbon, some of which are toxic.
Several sensors contain a phosphoric acid electrolyte. And a select few also contain lithium
chloride, sodium chloride and iodine which are toxic.
5.6.3 Flammable Gas Sensors
Pellistor based flammable gas sensors contain two pellistor beads known as the detector and the
compensator. The pellistor bead of the detector element contains very small traces of toxic
chemicals. The amounts involved are so small they do not represent any safety hazard. However
they should still be disposed of in accordance with guidelines laid down by any relevant safety
bodies as well as in accordance with local regulations.
