The sources is often always open up course of action factors or unintentional leaks in the process. When sources can be found, the practices supply steerage in pinpointing the degree in the hazard (Division one or Division two) and its extent. They also supply diagrams for typical circumstances that give suggested distances with the resource for that extent of the hazardous area.
