8.2. Exposure controls for hazardous components: No hazardous materials present

8.3. Personal protective equipment: Respiratory: Not required for normal handling. Protective gloves: Not required for normal handling, if tape is hot gloves are recommended as good industrial practice. Eye/Face: Safety glasses are recommended as good industrial practice.
