Potable Water Testing Kit

As described by World Maritime News, the entry into force of the Maritime Labour Convention (MLC 2006) in August 2013 will for the first time set out regulations specifying the need to maintain high quality drinking water standards onboard ship which protect crew from waterborne health risks.

In response, Wilhelmsen Ships Service (WSS) has launched the Nalfleet Potable Water Test Kit, which enables sea staff to monitor the quality of the potable water network onboard ship, providing tests for common infectious bacteria and in the process reduce the risk of possible risk to health by bacteria proliferation.

  • Global availability of all your water treatment needs through the world largest maritime network
  • Ensures safety and health for your crews
  • Easy to use and helps you to stay in compliance to WHO guidelines, ILO 178 (2009), MLC (Maritime Labour Convention, 2006) and flag state guidelines

Drinking water on board the vessel should be free of harmful bacteria such as E Coli and Coliforms which can cause infection and disease in humans. The maintenance, testing and recording of the quality of drinking water should be maintained in compliance with the ILO Maritime Labour Convention 2006 which comes into force in August 2013. The Nalfleet Potable Water Test Kit range enables ships staff to monitor the quality of the drinking water on board the ship by providing tests for important operational control parameters and verification tests for bacteria that can be of risk to human health. The range of tests can be used on the ship either as a standalone control solution or as a supplement to laboratory analysis, dependant on flag state guidelines. Improperly managed water is an established route for infectious disease transmission on ships. This was illustrated in a review of more than 100 outbreaks associated with ships undertaken by Rooney et al. (2004). One fifth was attributed to a waterborne route.

WHO “Guide to Ship Sanitation” (Third Edition)

“A ship operator’s role is to provide safe water to passengers and crew, fit for all intended purposes. Water on board should be kept clean and free from pathogenic organisms and harmful chemicals. Responsibilities are to monitor the water system, particularly for microbial and chemical indicators, to report adverse results under the IHR 2005, where required, and to take corrective action”.

Maritime Labour Convention 2006

The Marine Labour Convention (MLC) 2006 is the platform for the International Labour Organisation (ILO) to implement standards for the employment and living conditions for workers in the marine industry. These standards include the requirement that “Each member shall adopt laws and regulations or other measures to provide minimum standards for thequantity and quality of food and drinking water and for the catering standards that apply to meals provided to seafarers on ships that fly its flag, and shall undertake educational activities to promote awareness and implementation of the standards referred to in this paragraph.” (Standard A3.2 Food and Catering)
