WARNING – Bodily injury
Fibrous material
— The sensor and probe assemblies (standard and
high temperature versions) contain fibrous material
that can be a health hazard if airborne.
— The material, predominantly – aluminosilicate
refractory fibres, CAS 142844-00-6. Refractory
ceramic fibres (RCF) are classified as:
— Category 1B carcinogen under regulation (EC)
No 1272/2008 – the classification, labelling and
packaging regulations.
— Category 2B carcinogen by inhalation by The
International Agency for Research on Cancer
(IARC).
— When removing the sensor cover and subsequent
maintenance activities, exposure to the airborne
fibres could occur. ABB have conducted air
sampling assessments within the breathing zone of
the operator and have identified that an exposure
limit of 1 fibre / cubic centimetre is unlikely to occur.
— Exposure to any carcinogen must be kept as low as
reasonably practicable.
— Appropriate PPE defined below, must be
worn when working with probe assemblies
(all installation, replacement, maintenance
procedures):
— A face fit tested, half mask conforming to EN140
(or equivalent) with a level 3 particulate filter
conforming to EN 143 (or equivalent).
— Disposable protective coveralls in accordance
with Type 5 ISO 13982-1:2004 (or equivalent).
— Goggles and gloves.
DANGER – Serious damage to health / risk to life
Pressurized equipment – do not install / remove /
the sensor / probe if the process is at positive
pressure
Installation, operation, maintenance and servicing of
pressurized equipment must be performed:
— by suitably trained personnel only
— in accordance with the information provided in this
manual
— in accordance with relevant local regulations
— when process conditions are suitable to allow
enough to enable installation / maintenance
WARNING – Bodily injury
High temperature on exposed surfaces
— During operation, exposed sensor surfaces can
reach 200 °C (392 °F).
— Ensure suitable PPE is available and is worn before
handling the sensor.
— Do not touch exposed surfaces until the sensor /
probe is cool enough to handle with PPE.

operation
WARNING – Bodily injury
— The sensor weighs 9.0 kg (20 lb). When fitted with
a probe / filter assembly, the combined sensor /
probe weight is dependent on probe length / type
plus filter option – refer to the Operating instruction
(OI/AZ40-EN) for weight details.
— The sensor / probe assembly must be mounted in
accordance with the information supplied in the
Operating instruction (OI/AZ40-EN).
— Suitable lifting equipment must be available when
installing / removing the sensor / probe from the
process.
