A in-house emergency response team leader is sometimes confused with the in-house emergency response coordinator, but these are different functions. The team leader is part of the emergency response team with a valid first responder certificate. The coordinator head of the emergency response team does not need to have one and does not need to be part of the active emergency response team, but is the person who translates the safety policy into concrete implementation, maintains an overview of it and controls its implementation. The team leader has an operational function, checks the presence and status of all required materials and ensures that the knowledge of the company’s emergency response workers is kept up to date.
