What this lesson covers
This lesson walks through the construction medical services and first aid rule, from planning before the project starts to kits, emergency transport, 911 location posting and drenching facilities. It shows how to separate mandatory duties from advisory appendix language, a distinction the exam tests and one that decides what you actually owe on a jobsite.
