Boiler Manual - Weil-McLain

GV90+ gas-fired water boiler — Boiler ManualHandling ceramic fiber and fiberglass materialsHANDLING CERAMIC FIBERMATERIALSCeramic fibers can be converted to cristobalitein very high temperature applications. TheInternational Agency for Research on Cancer(IARC) has concluded, “Crystalline silicainhaled in the form of quartz or cristobalitefrom occupational sources is carcinogenic tohumans (Group 1).”:❏❏Avoid breathing dust and contact with skin and eyes.• Use NIOSH certified dust respirator (N95). This typeof respirator is based on the OSHA requirements forcristobalite at the time this document was written.Other types of respirators may be needed dependingon the job site conditions.
