Asbestos Use in the Maritime Industry
Asbestos has been a cornerstone in the maritime sector, notably in shipbuilding, due to its exceptional heat resistance and insulation capabilities. Yet, its use has come with severe health risks for marine workers. These risks include an elevated chance of lung cancer and other diseases linked to asbestos exposure.
History of Asbestos in Shipbuilding
The maritime industry's adoption of asbestos began in the early 20th century. Shipbuilders employed asbestos for insulation, fireproofing, and to fortify ship components. From 1940 to 1990, workers in shipbuilding and on ships were exposed to asbestos & are now facing a heightened lung cancer risk today. This is a direct consequence of their asbestos exposure during their careers.
Types of Asbestos Used on Ships
Ship construction predominantly utilized two asbestos varieties: chrysotile and amphibole. These fibers were integrated into various materials, such as insulation, gaskets, and friction products. This widespread use exposed marine workers to significant asbestos contamination hazards.
Asbestos-Containing Materials Found on Ships
Asbestos-containing materials (ACMs) are prevalent in various ship locations, including:
Joiner bulkhead systems
Insulation on hot water and steam piping
Boilers and tanks
Machinery parts
Bulkhead panels
Vinyl asbestos tiles for decking and flooring
Identifying and managing ACMs is paramount in the maritime sector to safeguard seafarers. Ship owners must engage Hazmat Expert companies for inspections and sample collection. These samples are then analyzed in approved laboratories, with results documented in the Inventory of Hazardous Materials (IHM) Part I.
The presence of asbestos on ships poses substantial health risks to marine workers. Asbestos dust can be released during installation, repairs, or when panels are disturbed. Flaking and cracking due to vessel vibrations at sea also release fibers, posing exposure risks and potential disease development.
Role of IHM in Mitigating Asbestos Risks
The Inventory of Hazardous Materials (IHM) regulation has emerged as a cornerstone in the maritime industry's ongoing fight against the significant risks associated with asbestos exposure. As a critical component of maritime safety, this regulation mandates the creation and maintenance of a comprehensive inventory detailing hazardous substances present on ships. This inventory not only identifies asbestos but also encompasses other perilous materials that could pose health risks to individuals working within the maritime environment. By implementing this proactive measure, the industry is equipped to enhance the management of hazardous materials, thereby significantly reducing the potential for asbestos exposure among workers. This initiative is essential for safeguarding the health and well-being of seafarers and shipyard workers, ensuring that their working conditions align with international safety standards and regulations designed to protect human health and the environment.
IHM surveys play a vital role throughout the entire lifecycle of a ship, beginning from its initial construction and extending all the way to its eventual recycling. These surveys are allowing for the identification and assessment of asbestos-containing materials (ACMs) and other hazardous substances. By pinpointing these materials, the IHM regulation ensures their proper management, handling, and disposal, which is crucial in minimizing health risks. The surveys are not merely a formality; they are a critical assessment tool that informs shipowners, operators, and workers about the presence and condition of hazardous materials onboard.
Asbestos Exposure Risks for Seafarers
Seafarers are at a heightened risk of asbestos exposure due to its widespread use in the maritime sector. Merchant Marine vessels, constructed with asbestos until the late 1970s, have led to increased rates of mesothelioma and other diseases among Navy veterans and former mariners. In 2019, over 70,000 workers died from past asbestos exposure, as reported by the European Commission in 2022.
Inhalation of Asbestos Fibers
Airborne asbestos fibers pose a severe threat to seafarers' health, as they can travel long distances and be inhaled by sailors working and living in confined spaces aboard ships. A study analyzing chest X-rays of 3,324 U.S. merchant mariners revealed that almost one-third (1/3) of them had abnormalities. This includes 38.5% of those exposed to asbestos over 40 years prior showing abnormal results. Seafarers who worked in engine rooms for more than 30 years were most affected, with 42.5% exhibiting chest X-ray abnormalities. This increases their risk of developing seafarers lung disease and other asbestos exposure symptoms.
Confined spaces on ships, such as engine rooms and boiler rooms, are high-risk areas for asbestos exposure.
Asbestos Exposure During Ship Maintenance and Repairs
Ship maintenance asbestos is a significant concern for seafarers, as repair and maintenance tasks can result in higher concentrations of asbestos fibers, even if only for short durations. A 2016 study published in "Inhalation Toxicology" found that while background asbestos concentrations on operating merchant ships were relatively low, certain tasks led to increased exposure.
As of December 2020, 55.6% of inspected vessels contained asbestos-containing materials, with 84 items classified in the highest risk category requiring immediate remedial attention. Asbestos has been found in various ship components, including pipework flange gaskets, woven pack and gasket materials, hand pumps, isolation valves, electrical components, and brake shoes for anchor windlasses.
It is crucial for the maritime industry to prioritize the health and safety of seafarers by implementing strict regulations and safety measures to minimize the risks of asbestos exposure. Proper training, personal protective equipment, and regular health monitoring are essential to protect the well-being of those working in this sector.
Health Effects of Asbestos Exposure
Exposure to asbestos fibers can lead to a range of serious health effects, notably among seafarers. These individuals have worked in confined spaces with asbestos-containing materials (ACM) on ships. The health impact of asbestos is profound, with long-term exposure significantly increasing the risk of life-threatening illnesses. This risk persists even without any known safe level of exposure.
Mesothelioma and Other Asbestos-Related Cancers
Mesothelioma, a highly aggressive cancer, is directly linked to asbestos exposure. Approximately 3,000 Americans are diagnosed with this disease annually.
According to Asbestos.com, mesothelioma can take anywhere from 20 to 60 years to appear after initial exposure to asbestos. Asbestos exposure also raises the risk of lung cancer and other cancers in the larynx, pharynx, stomach, colorectum, and ovary.
Asbestos.com advises that Pleural and peritoneal mesothelioma are the two most prevalent forms of the disease. In pleural mesothelioma, tumors develop on the lining of the lungs and chest wall, as well as on the diaphragm and other parts of the thoracic region.
Peritoneal mesothelioma involves tumors forming on the peritoneum, which lines the abdominal organs and the gut wall. Less common types of mesothelioma include pericardial and testicular mesothelioma.
Asbestosis and Lung Diseases
Asbestosis is a serious health consequence of asbestos exposure. It is characterized by long-term inflammation of the lungs due to asbestos fiber inhalation. There is no known treatment for asbestosis, and it is associated with complications such as lung cancer, mesothelioma, and pulmonary heart disease. Other asbestos-related lung diseases include pleural effusions, pleural plaques, and diffuse pleural thickening.
Latency Period of Asbestos-Related Diseases
The long latency period between exposure and symptom onset is a major concern for asbestos-related diseases. It can take decades for the health effects to manifest, making it challenging for seafarers to connect their illnesses to past asbestos exposure on ships. This latency period also complicates the process of seeking compensation for medical bills, lost wages, and pain and suffering resulting from work-related asbestos exposure.
Disease | Latency Period |
Mesothelioma | 20-50 years |
Lung Cancer | 15-35 years |
Asbestosis | 10-40 years |
Pleural Diseases | 10-30 years |
Epidemiological Studies on Asbestos and Seafarers
Epidemiological studies have illuminated the health risks associated with asbestos exposure among seafarers. Historically, the focus has been on shipyard workers, yet sailors on ships at sea have also faced significant risks. Research has highlighted elevated mesothelioma and other asbestos-related cancer risks among sailors.
The study examined 75,745 seafarers from 1985 to 2011, comprising 64% males and 36% females, over 1,245,691 person-years. It identified 4,159 cancer cases, with 3,221 in men and 938 in women.
Another study examined 81,740 male seafarers and 66,926 male fishermen, contributing 2,120,656 person-years for seafarers and 1,751,709 person-years for fishermen. The study found 19,228 cancers among male seafarers.
Various cancers, including mesothelioma, lung cancer, and urinary bladder cancer, showed significant increases.
These studies highlight the elevated risks of asbestos-related diseases, notably mesothelioma and lung cancer, among sailors exposed to asbestos. They underscore the critical need for ongoing monitoring, early detection, and comprehensive support for seafarers who have been exposed to asbestos during their careers at sea.
Regulations and Safety Standards for Asbestos on Ships
The maritime sector has made considerable strides in mitigating asbestos-related risks. It has done so through the enforcement of rigorous safety protocols and regulatory frameworks. The International Maritime Organization (IMO) has been pivotal in setting standards for asbestos management on vessels. These guidelines are designed to reduce health risks for seafarers, passengers, and maintenance personnel.
The IMO has mandated the prohibition of new installations of asbestos-containing materials (ACMs) on ships. Initially, SOLAS banned ACM installations on vessels constructed after July 1, 2002, with certain exemptions. This rule was enhanced in 2011, with SOLAS amended to ban all new asbestos installations on ships built after January 1, 2011.
International Maritime Organization (IMO) Guidelines
The IMO has established detailed guidelines for the upkeep and surveillance of materials containing asbestos on board. These guidelines, approved by the Maritime Safety Committee on May 28, 2002, underscore the critical need to minimize asbestos exposure for all individuals on vessels. Key elements of the IMO guidelines include:
Regular assessments of ACMs at intervals not exceeding 3 years
Initial inspections by qualified professionals to identify and locate ACMs
Planned repairs or removal of ACMs to be conducted by specialized personnel
Exposure assessments for crew members in areas with potential asbestos presence
Documentation and maintenance records related to asbestos management
SOLAS Convention and Asbestos Regulations
The SOLAS Convention has been instrumental in enforcing asbestos safety regulations within the maritime industry. The ban on new ACM installations on ships, as stipulated by SOLAS, has significantly diminished the risk of asbestos exposure for seafarers. Vessels constructed prior to the specified dates must adhere to IMO guidelines for managing existing asbestos, ensuring proper maintenance and surveillance to mitigate health risks.
Date | Regulation |
July 1, 2002 | SOLAS prohibits new installations of ACMs on ships, with some exceptions |
January 1, 2011 | SOLAS amended to prohibit all new asbestos installations on ships |
December 31, 2003 | Installation of asbestos on Australian ships prohibited |
The enforcement of these regulations and guidelines marks a significant advancement in ensuring the safety and well-being of seafarers and others on board vessels. By adhering to asbestos risk management practices and following IMO guidelines, the maritime industry strives to minimize health risks associated with asbestos exposure. This effort aims to create a safer working environment for all involved in the operation and maintenance of ships.
Asbestos, Health Concern, Seafarers, Ships
Despite regulations and efforts to reduce asbestos use, it remains a significant maritime industry health risk, posing a particular threat to seafarers on older ships. Asbestos-related diseases are more prevalent among sailors than shipyard workers. This disparity stems from sailors' prolonged exposure aboard ships.
Ongoing Risks for Seafarers on Older Ships
Sailors, who work and reside on ships around the clock, encounter exposure levels that surpass standard workplace norms. Asbestos fibers can persistently re-enter the air within the confined spaces of ships until they are either removed or contained. Background concentrations on ships can be high due to the motion and vibration of the vessel.
Asbestos measurements aboard ships have shown fiber concentrations from 0.001 to 0.152 fibers/cc (for fibers greater than 5 microns in length). The highest concentrations during active cleaning operations were up to 70 fibers/cc. Routine brake operations averaged 2.1 fibers/cc, and dry sweeping cleanup efforts measured as high as 3.4 fibers/cc.
Activity | Asbestos Fiber Concentration (fibers/cc) |
Active cleaning operations | Up to 70 |
Routine brake operations | Average 2.1 |
Dry sweeping cleanup | Up to 3.4 |
Welding activities | Upwards of 5 |
Importance of Asbestos Awareness and Safety Measures
Proper asbestos awareness for seafarers and safety measures are crucial to minimize exposure risks. Seafarers should be cautious around loose insulation, pipe wrapping, and asbestos deposits. Hiring professionals for brake repairs and avoiding disturbance of asbestos-containing materials are important preventive steps.
"An average worker inhales 6–8 million cubic centimeters of air during an 8-hour shift, equivalent to inhaling up to 16 million 'permissible' asbestos fibers under existing standards." (Source: Maritime Asbestos Exposure Data)
Asbestos Removal and Abatement on Ships
Asbestos removal from ships necessitates strict adherence to safety protocols and regulations. According to studies, over 50% of the 3000 surveyed vessels contained asbestos-containing materials (ACMs). Thus, ensuring proper asbestos removal on ships is critical to safeguard the health and safety of seafarers and shipyard workers.
The International Maritime Organization (IMO) has established clear guidelines for asbestos management on ships. Since July 1, 2002, new installations of ACMs on board ships have been allowed only in exceptional cases. As of January 1, 2011, new installations of ACMs on board ships are prohibited under any circumstances, as per the Safety of Life at Sea (SOLAS) Regulation II-1/3-5.
Proper Asbestos Removal Procedures
Safe asbestos handling and removal procedures are essential to minimize exposure risks during ship maintenance, repairs, or decommissioning. Trained professionals must handle asbestos abatement, adhering to strict safety protocols. The process involves several steps:
Containment of the asbestos-contaminated area
Wetting methods to reduce airborne fibers
Proper disposal of asbestos waste
Thorough cleaning and decontamination of the work area
Regulations mandate that asbestos removal on ships occur within 3 years from the date of contravention discovery. An Asbestos Management Plan (AMP) must be implemented within 3 months of asbestos identification on a vessel.
Personal Protective Equipment (PPE) for Asbestos Handling
Workers involved in shipboard asbestos remediation must employ appropriate personal protective equipment (PPE) to ensure their safety. Essential PPE for asbestos handling includes:
PPE Item | Purpose |
Respirators with HEPA filters | Prevent inhalation of asbestos fibers |
Disposable coveralls | Protect clothing and skin from asbestos contamination |
Gloves | Prevent skin contact with asbestos fibers |
Foot coverings | Prevent the spread of asbestos fibers outside the work area |
In addition to PPE, adequate ventilation and air monitoring are necessary to maintain a safe work environment during asbestos abatement on ships. By adhering to proper asbestos removal procedures and utilizing appropriate PPE, the maritime industry can effectively manage the risks associated with asbestos exposure. This protects the health of seafarers and shipyard workers.
Legal Aspects of Asbestos Exposure for Seafarers
Seafarers diagnosed with asbestos-related diseases may be entitled to asbestos exposure compensation from shipowners, maritime employers, or asbestos manufacturers. The Maritime Labour Convention (MLC, 2006), adopted on 23 February 2006 and entered into force on 20 August 2013, sets the minimum standards for the working and living conditions of seafarers. This includes health and safety provisions.
According to the National Mesothelioma Register (ReNaM) in Italy, 466 cases of malignant mesotheliomas (MM) were reported from 1993 to 2018. These cases were related to subjects with exclusive asbestos exposure in maritime settings. This accounts for 1.8% of the total defined exposure patients registered in the ReNaM. Among these cases:
453 (97.2%) were of the pleura
11 (2.3%) of the peritoneum
2 (0.4%) of the tunica vaginalis of the testis
Compensation for Asbestos-Related Diseases
Pursuing maritime asbestos lawsuits can significantly aid in covering medical costs, lost income, and suffering. In the UK, the highest weekly payment for Industrial Injuries Disablement Benefit (IIDB) is £207.60. The degree of respiratory disability, ranging from 1% to 100%, determines IIDB amounts. Those receiving IIDB may also qualify for a one-time lump sum, based on their respiratory disability assessment.
It's critical to initiate asbestos claims within three years from diagnosis. This deadline can start from the date of death if it's due to an asbestos-related disease. Many asbestos-related civil claims settle out of court, avoiding the need for a trial.
Liability of Shipowners and Employers
Shipowners and employers have a responsibility to provide a safe working environment. They may be held liable for failing to protect crew members from asbestos exposure.
Consulting with experienced maritime asbestos attorneys can help seafarers understand their legal rights and options for seeking justice. Legal claims and compensation processes for shipowner asbestos liability can involve complex medical assessments and legal navigation. This emphasizes the need for prompt legal advice to protect seafarer asbestos legal rights.
Conclusion
Asbestos has long been a hidden danger within the maritime industry, posing significant health risks to seafarers. Its use in shipbuilding, combined with its presence in confined spaces, increases the risk of asbestos-related diseases among maritime workers.
