The entry employer ensures that each attendant meets these duties. The attendant understands the hazards of the entry, including how exposure happens, its signs or symptoms and its consequences, and knows the behavioural effects exposure can produce in entrants. The attendant keeps a continuous, accurate count of entrants inside and makes sure the identification method under 1926.1206(d) correctly shows who is in the space. The attendant stays outside the space throughout entry operations until another attendant takes over; once relieved, the attendant may enter to attempt rescue only if the employer's program permits attendants to enter for rescue and the attendant is trained and equipped for rescue under 1926.1211(a). The attendant communicates with entrants to assess their status and alert them to evacuate, and monitors conditions inside and outside the space, ordering immediate evacuation if a prohibited condition exists, entrants show behavioural effects of exposure, an outside situation could endanger them, or the attendant is unable to carry out all attendant duties effectively and safely. The attendant summons rescue and emergency services as soon as entrants may need help escaping. When unauthorised people approach or enter during entry, the attendant warns them to stay away, tells them to leave at once if they have entered, and informs the entrants and entry supervisor. The attendant performs non-entry rescues as the employer's rescue procedure specifies and takes on no duties that could interfere with the primary job of assessing and protecting the entrants.
