Dear Senthil
DOP is the material listed in the endocrine disrupting chemicals and the confirmed carcinogens to animals. A synthetic lubricant named Emery 3004, from the class of compounds called poly-alpha olefins (PAOs), was approved by the OTSG on 8 January 1992 for use Army-wide as a safe replacement for DOP in hot smoke and cold smoke testing machines. Another less-viscous PAO, Emery 3002, was also approved by the OTSG on 24 February 1993 for Army-wide use in cold-smoke applications. The Ethyl Corporation (Boca Raton, LA) is the primary manufacturer of these PAOs, under the trade names Ethylflo 162 (repackaged as Emery 3002), and Ethylflo 164 (repackaged as Emery 3004).

Dear Shahid Ali,

Thank you very much for your valuable information.
