Abstract:

To reduce the possibility of flaming, the smoke formulation for the M8 smoke pot has been modified by the addition of a burn retardant, penterythritol PE. These M8-PE pots were chemically characterized to qualitatively and quantitatively determine the combustion products produced with the addition of PE. Data as needed prior to material release and for incorporation into the items Life Cycle Environmental Assessment LCEA. Similar to other terephthalic acid TA based smokes, benzene, formaldehyde, and carbon monoxide were the principal compounds observed of toxicological concern. A comparison is made between the M8-PE smoke pots and M8 pots, which shows that benzene appears to be lower in the PE pots but, formaldehyde appears to be higher. All concentrations exceed the currently accepted American Conference of Government Industrial Hygienists ACGIH Threshold Limit Values TLVS. Carbon monoxide levels are also much less in the PE pots, but were above the ACGIH TLVs. Other inorganic gas concentrations, such as nitrogen oxides and sulfur oxides, were determined, but comparisons were not made to the M8 smoke pots. Particle size analysis was conduced for the M8-PE pots with the observance of small diameter particles 1-2 micrometers.
