Flammable Vs Combustible Liquids<\/span><\/h1>[vc_column_text]Many researchers in the laboratories deal with chemicals and liquids routinely. Laboratories also <\/span>store the chemicals<\/span><\/a> as a reserve for future use.\u00a0<\/span><\/p>\n

The liquids used and stored in the laboratory may pose a serious risk to life and property if not handled and managed well. But what do the terms flammable and combustible mean? How do they differ?\u00a0\u00a0<\/span><\/p>\n

Let\u2019s understand the similarities and differences between Flammable vs Combustible Liquids. <\/span>[\/vc_column_text][vc_row_inner][vc_column_inner][vc_column_text]<\/p>\n

What are they?<\/span><\/td>\nFlammable & combustible liquids can ignite under the right conditions. Both pose serious risks to human lives, health, and safety.\u00a0<\/span><\/td>\n<\/tr>\n
What is flash point?<\/span><\/td>\nFlash point is the minimum temperature at which a liquid forms a vapour above its surface in sufficient concentration that it can be ignited. Liquids with <\/span>lower flash points<\/span><\/i> ignite easier.<\/span><\/td>\n<\/tr>\n
What is boiling point?<\/span><\/td>\nBoiling point is the temperature at which the vapour pressure of a liquid equals the external pressure surrounding the liquid.\u00a0<\/span><\/td>\n<\/tr>\n
What is the difference between flash point & boiling point?<\/span><\/td>\nEvery liquid has a boiling point, but only volatile liquids have a flash point.<\/span><\/p>\n

Boiling point can be observed with formation of bubbles inside the liquid, whilst flash point results in ignition above the liquid.<\/span><\/td>\n<\/tr>\n

How do flammable & combustible liquids differ?<\/span><\/td>\nAccording to NFPA 30:\u00a0<\/span><\/p>\n
    \n
  • A <\/span>flammable liquid<\/b> is defined as a liquid whose <\/span>flash point <\/b>does not exceed 100\u00b0F, when tested by closed<\/span>\u2010<\/span>cup test methods\u00a0<\/span><\/li>\n
  • A <\/span>combustible liquid<\/b> is one whose <\/span>flash point<\/b> is 100\u00b0F or higher, also when tested by closed<\/span>\u2010<\/span>cup methods.<\/span><\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
