Personal gas detectors calibration is required because of In the continuous drive to improve maritime safety, the regulatory bodies of the maritime industry strive to improve gas detection and measurement onboard ships by introducing new regulations. The latest regulation, which came into force in July 2016, by the International Convention for the Safety of Life at Sea (SOLAS), made it mandatory for all applicable vessels to carry portable gas detectors onboard.
According to Regulation XI-1/7, every ship is to carry at least one appropriate portable atmosphere testing instrument, which as a minimum, is capable of measuring concentrations of oxygen, flammable gases or vapors, hydrogen sulfide, and carbon monoxide, prior to entry into enclosed or confined spaces.
As advised in Regulation MSC.1/Circ.1477, “It should be noted that, given a ship’s specific characteristics and operations, additional atmospheric hazards in enclosed spaces may be present that may not be detected by the instrument recommended to be selected by these Guidelines, and in such cases, if known, additional appropriate instruments should be carried.”
The need for gas detection and measurement equipment and therefore, the need for Personal gas detectors calibration is a must. To be able to carry out calibration tasks effectively there is a wide range of instruments, both fixed and portable that are suitable for use on ships. Each unit is usually calibrated for specific gas and some have dual functions, such as combustible gas and oxygen.
It’s important to understand the limitations of the instruments, as well as their function and method of use. That’s why handbooks from the manufacturer should always be consulted for full information on the instrument before use.
