Qube CTW module still connected to CasTemp. A properly secured Qube CTW module
locating bracket system will not fail at this loading so the Qube CTW module is not
expected to fall from its location position
• Each Qube CTW module is clearly labelled on its rear surface with required regulatory
information including also a clear statement of maximum temperature:
! T max 85
0
C !
• The CasTemp Wireless instrument will indicate when a connected Qube CTW module is
approaching its maximum service temperature of 85
0
C
Risk Assessment Process
Following a risk assessment process in the deployment of Qube CTW module will help
ensure that exposure of Qube CTW module to potentially damaging external events is
minimised such that its already low potential to cause of harm can be virtually eliminated.
An example process is appended, providing examples of simple control measures to mitigate
the risk of damage to the module.
Conclusion
• The primary cause of hazard in use of Qube CTW module is exposure of the module to
some adverse external event which moves it outside of its normal operating specification.
• The design of Qube CTW module includes a number of primary and secondary features
which act to limit its inherent hazard potential to lie within those typically accepted in the
steel casting environment.
• For example, immersion of Qube CTW module into molten steel resulted in a hazard level
equivalent to the routine daily event of immersing Tundish hydrogen sensors.
• Existing caster PPE should provide sufficient protection for personnel in all identified
scenarios.
• The risk of exposure to hazard can be further reduced through implementation of simple
control measures by following a risk assessment process.
Recommendation
The user should carry out a risk assessment process and introduce control measures to
minimise/ eliminate the exposure of Qube CTW module to adverse external events, improving
safety, cost and system reliability.
