Course Description:
Recorded at AIHce EXP 2023
The ACGIH 2022 TLV announcement includes a notice of intended change (NIC) to the Nitric Acid exposure recommendation. That recommendation eliminates a full-shift Time-Weighted Average and revises the current STEL from 4 parts per million to 0.025 ppm inhalable fraction and vapor (IFV). This notice seems an ideal candidate for a direct-reading instrument survey. This education session will examine the direct-reading instruments currently available, using the instrument appendix from the AIHA Direct-Reading Instrument Body of Knowledge (DRI BOK) framework. Participants will decide whether there is a valid way to interpret direct-reading measurements to determine conformance to the ACGIH STEL for nitric acid as proposed.
Learning Outcomes:
Upon completion of the session, the participant will be able to:
• Use the knowledge, skills and abilities established by the AIHA DRI BOK.
• Describe the limitations and performance attributes that may /may not make the STEL NIC achievable.
• Demonstrate where policy or regulation may dictate its use (if moved from NIC to adopted by ACGIH).
• Provide a technical defense of planned actions in response to management or regulatory adoption of the NIC.
