Notice concerning oxygen analyzers

To Our Customers:

Use of and regulatory action on refractory ceramic fiber in Toray Engineering’s oxygen analyzers

On November 1, 2015, refractory ceramic fiber (hereafter “RCF”) was added to the chemical substances regulated under the Ordinance on Prevention of Hazards Due to Specified Chemical Substances (hereafter "the Ordinance").
This notice has been issued to inform our customers that RCF is used as insulation material for the sensors in our oxygen analyzers.

Impact on our customers

  • The latest revision of the Ordinance will not affect the use of oxygen analyzers that have been newly purchased or are already in operation.
  • RCF will not leak out of the oxygen analyzer if the product is used according to the user manual.
  • At the time of disposal, please inform the industrial waste processing service that there is RCF inside the oxygen analyzer.

For further details or inquiries regarding RCF, please consult the Labor Standards Bureau or the Labor Standards Inspection Office in your area.
