For the safe handling of n-tetradecane, the lower flash points and the upper flash point, fire point, AITs (auto-ignition temperatures) by ignition delay time were experimented. Also lower and upper explosion limits by using measured the lower and upper flash points for n-tetradecane were calculated. The lower flash points of n-tetradecane by using closed-cup tester were measured $104^{circ}C$ and $112^{circ}C$. The lower flash points and fire point of n-tetradecane by using open cup tester were measured $113^{circ}C$ and $115^{circ}C$, respectively. This study measured relationship between the AITs and the ignition delay times by using ASTM E659 apparatus for n-tetradecane. The experimental AIT of n-tridecane was $207^{circ}C$. The calculated lower and upper explosion limit by using measured lower $104^{circ}C$ and upper flash point $140^{circ}C$ for n-tetradecane were 0.63 Vol.% and 3.18 Vol%.
