Working in the marine sector is hazardous and challenging, with wide ranging risks to deal with, including severe weather, to working within restricted spaces, extreme temperatures, high humidity and dirty conditions.
The use of gas detectors is often compulsory: SOLAS regulations XI-1/7 requires that vessels have at least one portable gas monitor on board for oxygen and flammable gas detection. As a minimum it should measure concentrations of oxygen (O2), flammable gases or vapours, hydrogen sulphide (H2S) and carbon monoxide (CO) prior to entry into enclosed/confined spaces.
Marine vessels can present multiple gas hazards, which makes gas detection and monitoring crucial. The table below shows some examples of such vessels and applications.
Products installed on any marine vessel must comply with internationally recognized regulations. The international standards that apply to a vessel depend upon where it is registered.
Examples of countries and relevant standards are:
It is essential that products sold for use on a vessel comply with the standards relevant to the country in which the ship is registered. For example, products fitted to a European-registered vessel undergoing a re-fit in Singapore must comply with the European MED directive.
