# A-002 Initial Review Engineering Report
for PMN P-09-248p090248.eng INITIAL REVIEW ENGINEERING REPORT PMN: 09-0248 Focus Ready Draft 3/19/2009 ENGINEER: Arnold \ AG PV (kg/yr): 10,000

SUBMITTER: PN Solutions Inc USE: Flame retardant to fight forest fires via spraying onto vegetation (50%).Flame retardant for plastics (50%). No references found. P2REC: CRSS forward: P2 Claim: The substance will replace halogenated fire retardants currently used in plastics.

OTHER USES:

MSDS: Label:

CRSS : Chemical Name:

Consumer Use: No SAT (concerns) (03/10/2009): Migration to groundwater: Slow due to biodegradation PBT rating: P1B1T1 Health: 1-2 Drinking Water, Inhalation, Ingestion Page 1p090248.eng Eco: 3 Water (All releases to water with a CC = 1 ppb)
OCCUPATIONAL EXPOSURE RATING: 2-3A
NOTES & KEY ASSUMPTIONS: Generated by the 06/07/2005 version of ChemSTEER.

POLLUTION PREVENTION CONSIDERATIONS: P2 Claims: As a flame retardant on plants, the PMN substance appears to be environmentally friendly and not harm grass or tree leaves. It appears to have an LC50 of 500 mg/L, which is above the limit of 100 mg/L that the US Forest Service requires. It is a more effective flame retardant than diammonium phosphate, used in current products. The PMN substances causes wood in plants to char, rather than to burn, keeping a fire from spreading. For use as a fire retardant in plastics, the PMN substance will be used to replace chlorinated or brominated compounds. The substance is thermally stable up to 325°C, and can be processed into polymers such as nylons, olefins and polyesters up to 350°C. The substance causes a plastic to char instead of burning, which reduces the amount of smoke and vapors released during exposure to flames. P2REC: CRSS forward.

1 Exposure scenario titles consist of release activity followed by exposure calculation abbreviation. 2 Release activities are from engineering report's Manufact uring (Mfg), Processing (Proc) and Use release activity labels. Multiple release activities are combined in one exposu re scenario if their releases occur at same location. 3 Exposure calculations are Acute Dose Rate (ADR), Lifetime Average Daily Dose (LADD), and Probabilistic Dilution Model (PDM). There may be one, two, or all th ree exposure calculations per exposure scenario. CC is the aquatic concentration of concern. 4 This column displays concentration values for the 7Q10 streamflow, which is defined as the average daily streamflow of the seven consecutive days of lowest flow within a ten year period.
