What is the lowest temperature a liquid can ignite?

What is the OSHA standard for liquids?
The applicable OSHA standard is 29 CFR 1910.106–Flammable Liquids , which is based upon the 1969 version of NFPA®30 Flammable and Combustible Liquids Code. However, it is important to note that in 2012, in response to OSHA’s revised Hazard Communication standard (due to incorporation of the Globally Harmonized System [GHS]), OSHA revised 29 CFR OSHA 1910.106. The title of 29 CFR 1910.106 has been changed from “Flammable and Combustible Liquids” to “Flammable Liquids.” One significant change is the revised regulation lists liquids as “categories” rather than “classes.” However, the 2012 Edition of NFPA®30 has not been revised to reflect GHS guidelines. For instance, NFPA®30 continues to use the term flammable and combustible liquid and refers to “classes” of liquids.
What is the upper explosive limit?
