No they are correct, excuse my spelling but the "UNSYMMETRICAL DIMETHYL HYDRAZINE (FUEL) AND NITROGEN TETROXIDE (OXIDIZER)" fuels are not unlike that used on the old Titan missles stationed around the Wichita KS, Tucson AZ and Little Rock AR areas. The oxidizer will screw you up bad....trust me on this. Contact burn is only a minor hazard, Whole lot of USAF Missle troops got bit by this stuff well after they thought it was safe to handle.
Dangerous stuff , no BS.....DO NOT TOUCH and stay away. PLEASE ! Dig up your old shuttle landing videos and watch the crews is chemox suits inspect the shuttle before the hatch is opened......that is the reason IMO and experience.
Stay Safe !
What kind of heat would it take to burn these up? That stuff was glowing.
