A worker enters a tank, manhole, chamber or other enclosed space. Then suddenly he becomes unconscious. The natural reaction from a colleague may be: “Go inside and pull him out.” That reaction can turn one casualty into several. Confined-space hazards can include oxygen deficiency, toxic gases or fumes, fire and explosion hazards, engulfment and entrapment. A rescuer entering the same atmosphere without proper assessment, equipment and protection may be exposed to exactly the same hazard. Tal.sg That is why emergency rescue must be part of the planning before anybody enters. Before entry, ask: - Do we really need to enter the confined space? - Has the atmosphere been properly tested? - Are isolation and other controls implemented? - Is safe access and egress available? - Is somebody continuously attending outside? - Is communication established? - What happens if the entrant becomes unconscious? - What rescue equipment is available? - Who is trained to perform the rescue? - Can rescue be carried out without exposing another person unnecessarily? WSH personnel should not accept: “If anything happens, we call SCDF.” Emergency services may ultimately be required, but the workplace still needs a proper emergency-response and rescue arrangement. The WSH Council specifically states that employers should establish an emergency rescue plan, provide rescue equipment and appoint a confined space attendant as part of managing confined-space entry. Tal.sg The best rescue is the one we never need. But if something goes wrong, the rescue cannot depend on improvisation. Plan the entry. Test the atmosphere. Control the hazards. Prepare the rescue. Then enter.
