When developing a plan of action for more than 10 people, what is required?

A written plan is crucial when developing a plan of action for more than 10 people because it provides a clear, structured framework that outlines the roles, responsibilities, and procedures necessary for effective coordination and safety management in any situation involving hazardous materials.

Having a written plan ensures that all participants understand the objectives, strategies, and tactics that need to be followed in response to a hazardous situation. This documentation also facilitates accountability, as specific actions can be assigned and tracked, and it serves as a reference point to ensure that nothing is overlooked. In emergency management, particularly concerning hazardous materials, written documentation can also be essential for compliance with regulatory requirements and can assist in the after-action review process.

While oral communication is important for real-time situational updates, approval from legal counsel may be necessary for specific legal matters or contracts, and a verbal agreement lacks the clarity and enforceability provided by a written document. Thus, for larger groups where coordination and clarity are paramount, a written plan stands out as the best practice.
