In the field of lone worker safety, the term manalone has become increasingly recognised as shorthand for a specific and serious operational challenge: the condition of an employee who is working without the immediate presence of a colleague, supervisor, or any person who could assist them in an emergency. Every hazard that exists in a team working environment carries a different and more dangerous profile in the manalone condition. Understanding manalone safety — what it means, why it matters, and how to address it — is essential for any business with employees who work alone.
