Further inspection of the area found wadded paper towels soaked with linseed oil that were disposed in a trash container. The trash container bag wa

The paper towels retrieved were extremely warm to the touch, indicating spontaneous combustion had already begun.Lesson(s) Learned: Spontaneous heating occurs when a self-ignition combustible reacts with sufficient o

4、xygen from the air. This reaction is known as auto-oxidation, and results in the rapid evolution of heat and may eventually cause ignition. The MSDS for linseed oil and the label information have explicit warnings about the possibility of spontaneous combustion.Recommendation(s): 1. Before using any

Read your materials safety data sheet and become familiar with its hazardous properties and countermeasures.3. Oil
