My experience is get any literature reference and access to an electronic academic library, is especially for Process Safety field.
Reference for Process Safety is from ScienceDirect, the name of Journal is Loss Prevention in the Process Industries, Safety Science, Hazardous Material, and then from another electronic academic library is Wiley Inter science, the name of Journal is Process Safety Progress.
I hope my past experience can be a consideration for you.
Many thank's
Warm Regard's
