16 Data: Propylen (propen) CH 3 CH=CH 2 Boiling point: – 47,69 o C Density: 0,51 g/l (as liquid) LEL = 2,0 % ( ppm) UEL = 11,7 % Sax: ”A simple asphyxiant. No irritant effects from high concentrations in gaseous form. Flammable gas and very dangerous fire hazard when exposed to heat, flame, or oxidizers. When compressed to liquid form, can cause skin burns from freezing effects of rapid evaporation on tissue. Questionable carcinogen”.
