Pabco Insulation Division technical bulletin PTB-48-7A, which replaces PTB-48-7, describes a propane-torch test for telling whether old calcium silicate (calsil) insulation contains asbestos fibers. It states that asbestos-containing calsil should be identified to avoid accidental worker exposure, and notes that Pabco has marked its Super Caltemp production with a green stripe since December 1978 to show it is asbestos free.
