On-board ACM Disposal, IHM, Green Ship Recycling



Asbestos is a term used to refer to six naturally occurring silicate minerals. All are composed of long and thin fibrous crystals, each fibre being composed of many microscopic ‘fibrils’ that can be released into the atmosphere by abrasion and other processes. Asbestos is an excellent electrical insulator and is highly heat-resistant, so for many years it was used as a building material. However, it is now a well-known health and safety hazard and the use of asbestos as a building material is illegal in many countries. Inhalation of asbestos fibres can lead to various serious lung conditions, including asbestosis and cancer.

Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos was widely used during the 20th century until the 1970s, when public recognition of the health hazards of asbestos dust led to its prohibition in mainstream construction and fireproofing in most countries. Despite this, and in part because the consequences of exposure can take decades to arise, at least 100,000 people per year are thought to die from diseases related to asbestos exposure.


We conduct Asbestos/Hazmat Survey on your ships or facilities, after getting result of Asbestos from our accredited laboratory or IHM report, Before process, We conduct job safety analysis, risk evaluate and safe manner works, our professional team provide safe work as set up quarantine on your ships or facilities. After all safe works you will get International Valid Asbestos Free Certificate, You can be sure that getting professional service scope international and national laws, standards and regulations like OSHA & NIOSH from us.

Our professional team conduct to remove and dispose the other hazmats as ODS, Rockwool, Lead and Lead Compounds, Mercury, Radioactive Substances etc. all hazmats in IHM report part I,II and III.

Our team has qualification for conduct Asbestos Investigation and IHM Report.

What Is Work Classification?

The OSHA standard establishes a classification system for asbestos construction work that spells out mandatory, simple, technological work practices that employers must follow to reduce worker exposures. Under this system, the following four classes of construction work are matched with increasingly stringent control requirements:

  • Class I asbestos work is the most potentially hazardous class of asbestos jobs. This work involves the removal of asbestos-containing thermal system insulation and sprayed-on or troweled-on surfacing materials. Employers must presume that thermal system insulation and surfacing material found in pre-1981 construction is ACM. That presumption, however, is rebuttable. If you believe that the surfacing material or thermal system insulation is not ACM, the OSHA standard specifies the means that you must use to rebut that presumption. Thermal system insulation includes ACM applied to pipes, boilers, tanks, ducts, or other structural components to prevent heat loss or gain. Surfacing materials include decorative plaster on ceilings and walls; acoustical materials on decking, walls, and ceilings; and fireproofing on structural members.
  • Class II work includes the removal of other types of ACM that are not thermal system insulation such as resilient flooring and roofing materials. Examples of Class II work include removal of asbestos-containing floor or ceiling tiles, siding, roofing, or transite panels.
  • Class III asbestos work includes repair and maintenance operations where ACM or presumed ACM (PACM) are disturbed.
  • Class IV work includes custodial activities where employees clean up asbestos-containing waste and debris produced by construction, maintenance, or repair activities. This work involves cleaning dust-contaminated surfaces, vacuuming contaminated carpets, mopping floors, and cleaning up ACM or PACM from thermal system insulation or surfacing material.

What Methods Must Employers Use To Control Asbestos Exposure Levels?

For all covered work, employers must use the following control methods to comply with the PEL and STEL:

  • Local exhaust ventilation equipped with HEPA-filter dust collection systems (a high-efficiency particulate air [HEPA] filter is capable of trapping and retaining at least 99.97 percent of all mono-dispersed particles of 0.3 micrometers in diameter).
  • Enclosure or isolation of processes producing asbestos dust.
  • Ventilation of the regulated area to move contaminated air away from the employees’ breathing zone and toward a filtration or collection device equipped with a HEPA filter.
  • Feasible engineering and work practice controls to reduce exposure to the lowest possible levels, supplemented by respirators to reach the PEL or STEL or lower.

Employers must use the following engineering controls and work practices for all operations regardless of exposure levels:

  • Vacuum cleaners equipped with HEPA filters to collect all asbestos-containing or presumed asbestos-containing debris and dust.
  • Wet methods or wetting agents to control employee exposures except when infeasible (e.g., due to the creation of electrical hazards, equipment malfunction, and slipping hazards).
  • Prompt cleanup and disposal in leak-tight containers of asbestos-contaminated wastes and debris.

The following work practices and engineering controls are prohibited for all asbestos-related work or work that disturbs asbestos or PACM regardless of measured exposure levels or the results of initial exposure assessments:

  • High-speed abrasive disc saws not equipped with a point-of-cut ventilator or enclosure with HEPA-filtered exhaust air.
  • Compressed air to remove asbestos or ACM unless the compressed air is used with an enclosed ventilation system.
  • Dry sweeping, shoveling, or other dry cleanup of dust and debris.
  • Employee rotation to reduce exposure.
