Due to the serious threat posed to people working in enclosed spaces on board ships, the IMO has adopted mandatory requirements which requires all EU-registered vessels with a gross tonnage of over 500 tonnes to carry one or more gas detectors for atmosphere testing of hazardous gases prior to entry into an enclosed space.
The requirement enters into force on 1 July 2016, as SOLAS regulation XI-1/7.
Enclosed Space Entry
There have been a number of accidents where crew members have died during inspection and work in enclosed spaces (cargo spaces, tanks, non-ventilated stores rooms, etc.).
Recognition that the equipment fully complies with the requirements of the MED (
In accordance with the amendments to SOLAS regulation XI-1/7 contained in IMO Resolution MSC.380 (94):
– Every ship to which SOLAS Chapter I applies shall carry an appropriate portable atmosphere testing instrument or instruments;
– As a minimum, these shall be capable of measuring concentrations of Oxygen (O2), flammable gases or vapours (LEL), Hydrogen Sulphide (H2S) and Carbon Monoxide (CO) prior to entry into enclosed spaces;
– Instruments carried under other requirements may satisfy this regulation;
– Suitable means shall be provided for the calibration of all such instruments.
Atmosphere testing instrument for enclosed spaces:
“Every ship to which Chapter 1 applies shall carry an appropriate portable atmosphere testing instrument or instruments. As a minimum, these shall be capable to measuring concentrations of Oxygen, Combustible gases or vapours, Hydrogen Sulphide and Carbon Monoxide. Instruments carried under other requirements may satisfy this regulation. Suitable means shall be provided for the calibration of all such instruments.”
a1-cbiss offer a range of gas detectors to satisfy the SOLAS Regulations. We recommend buying a confined space entry detector which is capable of detecting the 4 main gases required to satisfy SOLAS regulation XI-1/7. Gas sensors can be swapped out to vary the configuration between oxygen, hydrogen sulphide, carbon monoxide and combustible gases. In some 4-gas detectors, there is an option to add an exotic toxic gas for example, sulphur dioxide or nitrogen dioxide.
a1-cbiss recommend the wheel marked Ventis MX4 because it is available as non-pumped gas detector for general use onboard ships. The slide on pump converts the instrument into a pumped version to enable a gas sample to be drawn prior to entry in confined spaces.
Docking stations provide functional bump tests and calibration checks to ensure that the gas detectors are ready to use onboard the ship and will provide accurate monitoring.
a1-cbiss recommend the DSX Docking Station because all Industrial Scientific gas detectors can be docked on it, eliminating the need to buy docking stations for each type of gas detector.
a1-cbiss have recently introduced the GMI PS200 and PS500 to the product portfolio. These multi-gas detectors are also MED approved and comply with SOLAS regulation XI-1/7. The PS200 has an optional built in pump which can be switched on for pre-confined space entry and switched off again to preserve the battery power.
