  • In order to investigate the compatibility of data in MSDS(Material Safety Data Sheet), the flash point of xylene isomer was measured by using Pensky-Martens closed cup (ASTM D93), Setaflash closed cup(ASTM D3278), Tag open cup(ASTM D1310), and Cleveland open cup (ASTM D92) testers. Also, the AITs(autoignition temperatures) of xylene isomers were measured by using ASTM E659-78 tester. The measured the flash points and the AITs were compared with literatures and MSDS in KOSHA(Korea Occupational Safety and Health Agency). The measured the flash points and the AITs were different from those in literatures and MSDS. As a result, this paper is shown that it is needed to investigate combustion characteristics of xylene isomer for the fire safety objectives.

  • This study measured the AITs of n-butanol + n-decane system from ignition delay time (time lag) by using ASTM E659 apparatus. The AITs of n-butanol and n-decane which constituted binary system were $340^{\circ}C$ and $212^{\circ}C$, respectively. The experimental AITs of n-butanol + n-decane system were a good agreement with the calculated AITs by the proposed equations with a few A.A.D. (average absolute deviation).

  • An accurate information of the autoignition temperature(AIT) is important in developing appropriate prevention and control measures in industrial fire. This study measured the AITs of trichlorosliane and dichlosilane(DCS)-trichlorosliane(TCS) mixtures by using ASTM E659-78 apparatus. The experiment AITs of trichlorosliane, TCS(90wt%)-DCS(10wt%) and the TCS(70wt%)-DCS(30wt%) were $225^{\circ}C,\;250^{\circ}C\;and\;236^{\circ}C$, respectively.

  • The flash point and the AIT(auto-ignition temperature) are the most important combustible properties used to determine the potential for the fire and explosion hazards of flammable material. In order to know the accuracy of data in MSDS(Material Safety Data Sheet), the flash point of n-acids were measured by using Pensky-Martens closed cup tester(ASTM D93), Setaflash closed cup tester(ASTM D3278), Tag open cup tester(ASTM D1310) and Cleveland open cup tester(ASTM D92). Also, the AIT of n-acids were measured by using ASTM E659-78 tester. The measured the flash points and the AIT were compared with literatures and MSDS in KOSHA. The measured the flash points and the AIT were different from those in literatures and MSDS. Therefore, This paper shows that it is needed to investigate the MSDS compatibility of n-acids for the fire safety objectives.

  • The autoignition temperature (AIT) of a material is the lowest temperature at which the material will spontaneously ignite. The AIT is important index for the safe handling of flammable liquids which constitute the solvent mixtures. This study measured the AITs of n-hexanol+p-xylene system by using ASTM E659 apparatus. The AITs of n-hexanol and p-xylene system which constituted binary system were $275^{\circ}C$ and $557^{\circ}C$, respectively. The experimental AITs of n-hexanol+p-xylene system system were a good agreement with the calculated AITs by the proposed equations with a few A.A.D.(average absolute deviation).

  • For the safe handling of 3-hexanone(ethyl propyl ketone), this study was investigated the explosion limits of 3-hexanone in the reference data. The flash points and AITs(auto-ignition temperatures) by ignition delay time were experimented. The lower flash points of 3-hexanone by using closed-cup tester were experimented at $18^{\circ}C$. The lower flash points of 3-hexanone by using open cup tester were experimented in $27^{\circ}C{\sim}32^{\circ}C$. This study measured relationship between the AITs and the ignition delay times by using ASTM E659 tester for 3-hexanone. The experimental AIT of 3-hexanone was at $425^{\circ}C$. The lower explosion limit( LEL) by the measured lower flash point of 3-hexanone was calculated as 1.21 Vol%.
