Literally 'initial response person'. A broader term for any first responder, including emergency services and sometimes security personnel. More formal and used in official contexts.

A person who answers or replies, such as in a survey, discussion, or correspondence.
Respondent, especially in surveys, questionnaires, or formal inquiries. The most natural term for someone who provides answers.

Choose the term based on context. For emergency personnel, use specific roles like 救急隊員, 消防士, or 警察官. For devices, 応答装置 or トランスポンダ are appropriate. For survey respondents, 回答者 is best. Avoid using レスポンダー in general conversation; it sounds unnatural.
Emergency medical personnel are sometimes called 'responders', but it's not common.
Directly translating 'responder' as レスポンダー is often unnatural. Japanese prefers specific terms based on the role or context. Only use レスポンダー in technical fields where it is established jargon.
