Safety is Everyone's Business. The official "Safety Triumvirate" on Set includes the 1st AD, the Key Grip, and Stunt Coordinator or the Intimacy Coordinator, depending on the action. Anyone can speak to any of these Department Heads, regardless of their position on the Call Sheet. If you witness something, say something. However, saying something in the moment isn't always possible, which is why there are five (5) elements of Bystander Intervention: 1. Distract: Ask a question or discuss something unrelated to change the subject 2. Delegate: Report it to the appropriate person 3. Document: Write it down 4. Delay: Check in later 5. Direct: Speak up in the moment You can also call the Safety Hotline on the Call Sheet to report it.

There is a very clear chain of command on set as well as specialized authority regarding particular risk elements. The daily safety meeting should already be clearly identifying who has final word regarding any special elements in the days work (stunts, effects, etc), typically the HOD of the element in question. If an actor just refuses to reign it in, it's time to have a Producer intervention. The actor is in breach of contract, and said contract will likely contain descriptions of financial penalties.

I’d call an all stop, if safety training needs administering so that we can all operate safely it’s worth it. There is no job in the world that’s not coming home from.

Address the actor privately to reinforce the importance of safety protocols, and if necessary, pause the shoot to reiterate rules to the entire crew for everyone's protection.
