30、e gas detectors used for testing of the atmosphere in enclosed spaces onboard ships prior to entry into those spaces, as required by SOLAS regulation XI-1/7 “Atmosphere testing instrument for enclosed spaces”.This document specifies the characteristics that portable gas detectors should be assessed

31、against items such as: which gases can be measured, sensitivities, indications, alarm levels, protection against shock, temperature and water ingress, and additional requirements for spaces or areas where a risk of explosion exists.This document specifies the marine environmental conditions in which

32、 portable gas detectors are expected to be used.This document does not define differences between gases and vapours, nor does it give technical detail on calculations and methodology for explosive limits and operational exposure levels. The intent of this document is to simplify the subject to the e

33、ssentials and use references for the actual scientific standards if more detailed explanations are required.Portable gas detectors conforming to this document should only be used onboard ships in accordance with IMO requirements and procedures.This document does not provide a specification on how to

34、 use portable gas detectors, or how to enter enclosed spaces.

Flammable vapours/gases which are not marked cannot be measured or detected by the portable gas detector.NOTE 2 Iso-butane is an alternative calibration gas of portable gas detectors in measuring propane an
