ACGIH® TLV®-CS Committee Studying Nanoscale Primary Particle Notation
On January 30, 2015, the American Conference of Governmental Industrial Hygienists (ACGIH®) announced the under study list for its Threshold Limit Values for Chemical Substances (TLV®-CS) Committee. See http://www.acgih.org/tlv/CSTLVStdy.htm The under study list includes, under other issues under study, "nanoscale primary particle notation." According to ACGIH®, the under study list serves as "notification and invitation to interested parties to submit substantive data and comments to assist the committees in their deliberations." See http://www.acgih.org/TLV/DevProcess.htm The TLV®-CS Committee will consider only those comments and data that address issues of health and exposure, but not economic or technical feasibility. ACGIH® states that comments must be accompanied by copies of substantiating data, preferably in the form of peer-reviewed literature. By July 31, 2015, ACGIH® will update the TLV®-CS Committee's under study list into a two-tier list:
- Tier 1 consists of chemical substances and physical agents that may move forward as a notice of intent to change (NIC) or notice of intent to establish (NIE) in 2016, based on their status in the development process; and
- Tier 2 consists of chemical substances and physical agents that will not move forward, but will either remain on, or be removed from, the under study list in 2016.
ACGIH® states that the best time to submit comments is in the early stages of the TLV® development process, preferably while the substance or agent is on the under study list.
