This memorandum confirms that no occupational handler risk assessments are being conducted for the antimicrobial uses of chloropicrin during the current round of registration review.   This is consistent with the 2014 FWP which states on page 5: 

      New occupational handler exposure assessments are not anticipated unless new studies become available or points of departure or uncertainty factors change.
      
The antimicrobial use of chloropicrin is as a wood preservative product.   A new chloropicrin wood product (SmartFume) was registered in March 2018; however, exposures are anticipated to be less than those with the original product (Timberfume II) because the new product is packaged in 45 gram cartridges.   There are no new toxicity studies and the points of departure and the uncertainty factors have not changed since the 2009 Amended RED.
