Asbestos is a kind of mineral fibrous which has flexible elongate silicate. Asbestos or asbestos products are widely used in automotive, chemical, shipbuilding, electrical equipment and other industries. More than 3500 kinds of asbestos-containing materials get used on board. Products containing asbestos in the course of impact, vibration, impact friction, repair or move release asbestos cilia easily, by means of pollution of air, water or food, into the human body through the respiratory and digestive tract, inhalation of asbestos fibers can lead to asbestos lung, malignant mesothelioma, lung cancer, pleural plaques and other deadly diseases. Considering the asbestos hazards to humans and the environment, relevant international organizations and countries gradually introduce provisions that asbestos production, use and disposal are strict restrictions or requirements, "2009 Hong Kong International Convention on the Safe and Environmentally Sound Recycling of Ships" from IMO take asbestos into the "control of hazardous substances," clearly requires all ships to prohibit newly installed asbestos-containing material.Considering the International Standardization Organization (ISO) asbestos testing standards ISO/DIS22262-1 recommendations and suggestions for scanning electron microscopy(SEM), pointing at the provisions of the International Maritime Organization and classification society ban on asbestos products on board, This paper proposed Trace ship products scanning electron microscopy methods asbestos. By asbestos collection, asbestos sample preparation, asbestos sample preparation, asbestos samples by scanning electron microscopy and influencing factors research and analysis, a scientific marine products trace asbestos scanning electron microscopy methods and processes. Through the semi-submersible engineering vessel carrying out the entire ship Non-asbestos detection complete trace asbestos SEM detection method practical engineering applications. The scanning electron microscope methods of trace asbestos in marine products test all marine products for new shipbuilding and ship repair, ensuring that no content in the products, avoiding the costs and other economic losses and legal risks of ship stranded due, shipment delays, expensive replacement caused by asbestos problem, protecting the crew living and working environment and health.
