3 Health & Safety
3.1 Safety precautions
Be sure to read, understand and follow the instructions
contained within this document before and during use of the
equipment. Failure to do so could result in bodily harm or
damage to the equipment.
3.2 Potential safety hazards
3.2.1 Process conditions and requirements
3.2.2 Endura AZ40 sensor – fibrous material in probe
assembly
3.2.3 Endura AZ40 sensor / probe – installation to
pressurized process
WARNING – Bodily injury
Installation, operation,
maintenance and servicing must be performed:
— by suitably trained personnel only
— in accordance with the information provided in
this document
— in accordance with relevant local regulations
WARNING – Bodily injury
Environmental conditions
— High air / equipment / structure temperatures, poor
air quality and adverse environmental conditions
may be present when the process is running.
— It is recommended that the process is shut down
before performing these procedures.
— The process must be cool enough to enable
shutdown, disconnection and removal of the sensor
in a safe manner and in accordance with relevant
local regulations.
— Appropriate PPE, including mask and goggles must
be worn when preparing the process for these
procedures.
WARNING – Serious damage to health
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
document
— in accordance with relevant local regulations
— when process conditions are suitable to allow
enough to enable installation / maintenance
