8.2 Exposure controls
Use local exhaust ventilation to maintain airborne concentrations below the TLV. Suitable respiratory
equipment should be used in cases of insufficient ventilation or where operational procedures demand it.
For guidance on engineering control measures refer to publications such as the ACGIH current edition of
'Industrial Ventilation, a manual of Recommended Practice.
8.3 Personal protective equipment
Engineering measures
Provide sufficient ventilation for operations causing dust formation. During thermoplastic reprocessing at
elevated temperatures, where risk of mist emission from the aliphatic polyol component exists, provide
sufficient ventilation. Follow occupational exposure limit values for dusts or mists, where applicable.
Ventilate as needed to control airborne dust or mist. Use explosion-proof electrical equipment if airborne
dust or mist levels are high.
Personal protective equipment
Respiratory protection:
In case of dust: Use a NIOSH/MSHA approved air purifying respirator as needed to control exposure.
Consult with respirator manufacturer to determine respirator selection, use, and limitations. Use positive
pressure, air-supplied respirator for uncontrolled releases or when air purifying respirator limitations may
be exceeded. Follow respirator protection program requirements (OSHA 1910.134 and ANSI Z88.2) for
all respirator use. In case of risk of inhalation of mists during thermoplastic reprocessing at elevated
