Remarks:This product is solidified during the forming process, so there are no hazards in particular during normal use.
Dust or particles generated during cutting and grinding may include a small portion of the product, but it is not harmful. However, such dust or particles may include the material being processed, in which case the MSDS of the material should be consulted.
Consult a doctor in the following cases, if necessary:
* inhalation
* skin contact
* eye contact
* ingestion
Local ventilation:If necessary due to the above cases, a ventilation system should be used.
Dust Prevention measures:If necessary due to the above cases, a dust collection system should be used.
