4 Summary This asbestos risk survey was carried out in accordance with the guidelines laid down in the BRL 5052 standard; 1. consultation between client and manager 2. desk research and design of inspection plan 3. visual inspection 4. sampling and analysis results Initially, in as much as possible, consultation took place with the manager. Subsequently, wherever the client offered construction drawings and specifications for inspection, desk research was carried out. All details of such research are recorded in paragraph 2.2 of this report. An inspection plan (project file) was subsequently drawn up. The visual inspection on site was carried out according to this inspection plan. Wherever possible samples were taken of the materials suspected of containing asbestos, as found, in order to demonstrate the asbestos content. These samples were analyzed by a duly approved laboratory. In the analysis certificates from the laboratory, appearing in the appendices, the nature of the asbestos-containing materials has been determined. The nature of the asbestos-containing materials may be relevant for the choice of removal method. If sampling was not possible, an indication is given of any other means by which the asbestos content was demonstrated (for example consulting documentation or visual recognition). In the table on the next page the asbestos containing materials that were found have been listed. The photographs have been included in paragraph 2.3. If a material cannot be determined to be asbestos-containing, but is visually marked to be suspected thereof, it has also been included in the above-mentioned table. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page III

Remarks: Possible locations, areas and/or spots found inaccessible during the survey have been marked accordingly in the floor-plans included in appendix A. It is therefore strongly recommended to carry out additional destructive spot surveys immediately prior to start of demolition and/or conversion! Walls and/or areas suspected to be covered with sheeting containing asbestos have been excluded from the survey because such sheeting can not be removed without taking extensive additional safety precautions. ¹) quantities of asbestos infected materials found during the survey are on the spot estimates only and as such unfit for planning and/or calculation purposes. The buildings were in use during the inventory survey. In the course of the survey the structure of the inner façade became apparent. The inner façade consists of panels each 3 meters wide and 1.15 meters high. They are stacked onto each other. The vertical partition is filled with a rubber flap and in a few cases asbestos containing sealant. The horizontal partition however was in all the instances filled with an asbestos containing sealant when present and uncovered. Therefore all the facades indicated in the floor plan by a red line must be considered either asbestos containing or asbestos suspicious. Seeing that almost all the sealants used on the buildings examined contain asbestos and keeping in mind that the samples have been taken randomly and don t cover the entire facades caution should be taken when in an asbestos free zone sealant is discovered. On none of the investigated locations asbestos isolation or panels have been observed. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page V

7 From the survey done on the facades of buildings Ch, Ck and Dj it is safe to presume that the same construction is used throughout the entire buildings mentioned. Therefore these façades can be assumed free of asbestos. On all the facades the inner facade is covered by a layer of bituminous roof covering. This layer is glued to the wall with a layer of bituminous adhesive. On one location asbestos fibers have been found in this bituminous adhesive (Bf east facade, certificate of analysis 75115, sample 4). On all other sample locations the layer of bituminous adhesive was too thin for analysis. Possibly an asbestos containing adhesive has been used on all the facades. In case of work being carried out on the facades further investigation is advised. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page VI

9 1. Introduction 1.1 Oesterbaai engineers This document is the report of a full asbestos survey. All work was carried out in accordance with the statutory requirements laid down in the BRL 5052 standard. This report complies with these statutory requirements. Companies are authorized to produce such reports if they hold a current KOMO certificate for asbestos surveys. The asbestos survey must be carried out expertly, in order to avoid health risks for the inspector and the immediate surroundings. The employees of Oesterbaai engineers deal consciously with health risks. The surveys by Oesterbaai engineers are only carried out by expert, experienced individuals, who hold at least a DTA certificate. This report was prepared with the greatest possible care. If its fails to meet your expectations, or should you have any further questions or comments, we would be delighted if you would contact us directly. 1.2 Asbestos in general Asbestos is a fibrous mineral material, that in the past was very widely used, above all in construction. Non-flammability, excellent wear resistance, moisture resistance and low price are the main, positive characteristics of asbestos. Asbestos-containing materials are always composite materials; in other words, made up of several different materials. Because asbestos fibers do not adhere to one another, a binding agent is required, such as for example cement. Asbestos is almost always used as an additive. The service life of the composite material thus created is in most cases determined by the binding agent, because asbestos itself is indestructible. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 1

10 A reduction in the binding effect is also identified as a reduction in the adhesion bonding of asbestos fibers. If the adhesion bonding of the material is reduced, fiber emission can increase. This may represent a risk to health. Working with asbestos or asbestos-containing materials has already been banned (with just a few exceptions) for some considerable time. This is because inhalation of asbestos fibers represents a major threat to health. A detailed explanation is contained in chapter six. Terminology Below is a brief explanation of commonly used terms. asbestos The fibrous silicates actinolite, amosite, anthofyllite, chrysotile, crocidolite and tremolite, and products in which these silicates are processed. asbestos analysis The analysis of a material or air sample for the presence, type and percentage / concentration of asbestos, carried out by an approved laboratory. asbestos survey There are three types of asbestos survey which can be carried out on the basis of the BRL 5052 standard: asbestos risk survey suitable prior to scrapping and/or renovation (public law obligation on the basis of the Asbestos Removal Decree and municipal building regulations) outline survey, for example in the framework of sale risk survey, in a non-demolition/scrapping situation, focusing on the risks of the presence of (not protected, non-adhesion bonded) asbestos BRL 5052 The National Evaluation Guideline for the KOMO process certificate for asbestos surveys, accepted by the Construction Harmonisation Committee of the Construction Quality Foundation. containment The construction using which the area to be cleansed is screened from the environment. In this construction, a statutory level of underpressure is maintained, to prevent the emission of asbestos fibers to the environment.. DTA certificate A DTA (Expert Supervisor Asbestos Removal) is an expert who has completed DTA training, followed at a training institute approved by the Ministry of Social Affairs and Employment, with a final examination. sampling Taking random samples in such a manner that from a defined batch a representative picture emerges of the characteristics of that batch. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 2

12 2. Investigation and results 2.1 Investigation method For the implementation of an asbestos survey, a systematic work approach is followed. Firstly, wherever possible, consultation takes place with the location manager. This is followed by desk research based on construction drawings and specifications, if provided by the client, whereby an inspection plan is also drawn up. Subsequently, the location is systematically inspected for the presence of materials suspected of containing asbestos, in accordance with the predetermined inspection plan. In this process, samples are taken of materials suspected of containing asbestos. These samples are submitted for analysis to a duly approved laboratory. 2.2 Results of consultation between client / manager and desk research consultation with name of manager result manager yes mister J.L. Bock information on: known asbestos sources in the facades (3rd floor) historic modifications on the buildings prior surveys no reason: desk research drawing numbers result yes NA no relevant information no project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 4

13 2.3 Results of visual inspection & sample analysis During the visual inspection, materials suspected of containing asbestos, which emerged from the preparations, were inspected. Investigations were also initiated into possible secondary contamination. This refers to (residual) asbestos waste left behind following a previously implemented asbestos remediation process. A visual inspection was then carried out for other materials suspected of containing asbestos. To be able to state with 100% certainty that a suspicious material is asbestos-containing, an analysis of a sample of that material must be carried out by an expert laboratory. If in any other manner than via analysis results, it emerges that a material is asbestos-containing, this is indicated as follows: Intechnium asbestos manual, visual observation or material stamp with year figure. If no sample is taken because sampling is hazardous for the inspector(s), this is specified as follows: chimney on roof or paneling at considerable height. On the floor plans in the appendices, the asbestos-containing materials identified are indicated. For the sake of clarity, photographs and detailed specifications of these materials are contained in this paragraph. There are also photographs of the materials inspected, suspected of containing asbestos, which turned out to be NOT asbestos containing. These materials are also included to avoid confusion during asbestos removal work. The numbers of the locations correspond to the numbers on the floor plan and the photographs. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 5

Because of the woodwork and the roof covering and in avoidance of leakage it was not possible to take a sample of the sealant in the inner facade. Most likely also here the asbestos containing sealant is present in the horizontal partitions of the inner facade. However the structure of the facades and the materials used are the same as the rest of asbestos containing facades. It is most likely that the same asbestos containing sealant has been used here. picture: 6, seal (sealant) project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 16

In the hallway they are covered by a gypsum wall. The old inner facade extends to the south side of the building. In the adjacent technical room it is also visible above the gypsum wall. A sample is taken from the sealant in the partitions between the panels. - A hole is drilled in the top right panel of the ground floor in the outside entrance corridor to investigate how far this paneling extends to the north side of the building. No inner facade is present here therefore two additional holes are drilled nearer to the inside hallway. No inner facade is present at these locations either at the level of the ground floor. It is not possible to investigate the facade at a higher level. No sample is taken here. picture: 8, seal (sealant) project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 19

It extends through the passage to the north side off the building. Being indoors no sample is taken here but the sealant is visually recognized as being identical to the sealant in the Cf east facade. Also above the ceiling on the second floor the same facade and sealant is observed. In the second floor hallway it is covered by a gypsum wall. - To investigate the extends of the inner facade to the south side of the building a hole is drilled in the outer facade in the outside entrance corridor. Here also the inner facade is present. No sample of the sealant can be taken here since the drill hole is not on a partition but most likely the sealant in the partitions is asbestos containing.

48 3. Limitations of the asbestos survey 3.1 Limitations of the asbestos survey, in general In every asbestos risk survey carried out by Oesterbaai engineers, work is carried out very thoroughly and systematically. Particular attention is paid to tracing all asbestos-containing materials. Based on thorough preparation, the use of expert and experienced personnel and implementation of the asbestos survey according to a well conceived plan, the risk of missing asbestos-containing materials is kept to a minimum. However, there is always a slight risk that asbestos-containing materials will not be identified as such, given the fact that more than 3500 applications of the material are known. The investigation is merely an observation of a given moment. Oesterbaai engineers are not responsible for anything which may have changed at the investigation location, after the investigation date. This report is the result of a duty of effort, not a duty of results. 3.2 Limitations due to constructional inaccessibility This asbestos risk survey is aimed at identifying all asbestos-containing materials. However, there are certain situations which can only be inspected by means of destructive methods. Examples are: asbestos cement pipes cast in foundations or asbestos cement adjustment plates under or beneath walls, creep spaces concealed or filled with rubble, etc. It is always possible that concealed asbestoscontaining applications may go unnoticed due to constructional inaccessibility. 3.3 Locations where no inspection for asbestos was carried out Whenever the survey is carried out on a building which is in service, the fewest possible destructive actions are undertaken. This applies explicitly also for pipe insulation, which means that all pipe insulation is subject to the limitations of constructional inaccessibility, with the exception of locations where damage down to the core is visible, or where the material is sampled. In shafts, twin-walls, chimneys and other locations only accessible through destructive investigation, and where no destructive investigation was carried out, visual inspection was undertaken. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 40

49 4. Proposal for asbestos removal 4.1 Outsourcing removal In the Netherlands, it is legally required that the asbestos first be removed from a property or property to be demolished, and that only once this has been carried out other demolition work can be started. Companies are authorized to remove asbestos if they hold the KOMO process certificate asbestos removal (BRL5050). For the removal of asbestos-containing material, a range of certified removal companies can be invited to submit an offer. 4.2 Asbestos removal techniques For the removal of asbestos-containing materials, a number of techniques are available. The techniques are aimed at limiting to a minimum the spread of asbestos fibers into the environment, and reducing as far as possible health risks to the implementing staff. The removal methods are broken down into four categories, below: 1. use of a containment: If a containment is used, an air-tight work space is created around the location of the asbestos source. The air seal ensures that no emission of asbestos fibers into the environment can take place. In the work space, underpressure is created using a powerful extraction installation. This installation contains a very fine filter that filters the asbestos fibers from the air in the work space, and discharges only clean air. The air in the work space is continuously refreshed. Having created the underpressure, a start can be made on removing the asbestos-containing materials. This is carried out by operators in special protective clothing wearing breathing apparatus. Once all asbestos has been removed, an air measurement (release) is carried out by an independently certified and accredited laboratory. Only once the volume of asbestos fibers measured in the air falls below the statutory minimum threshold, may the containment be removed. 2. use of a glove bag: A glove bag is a special bag wrapped airtight around the asbestos-containing material. The bag features pre-formed gloves to allow working in the bag, without any emission of asbestos fibers taking place into the environment. The operators also wear special protective clothing and breathing apparatus, as a preventive measure. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 41

50 3. outside remediation: Outside remediation takes place if all asbestos removal takes place without an air seal, in the outside air. This is only permitted in a limited number of cases, for example if the asbestos-containing material can be removed without damage, so that there is no risk of the emission of asbestos fibers into the environment. For such a situation, the asbestos-containing material must be very hard, have good adhesion bonding, and be easily removable. Safety regulations state that contractors are required to wear protective clothing and breathing apparatus. At the end of the work, a visual inspection must be carried out. This is carried out by an inspector of a STERIN-approved laboratory. 4. direct wrapping: Direct wrapping is permitted if the asbestos-containing material is attached to an easily removable object, or is already loose. The asbestos source is first impregnated with a latex-based spray. The asbestos-containing material is double-wrapped entirely, and disposed of as asbestos-containing waste. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 42

51 4.3 Advice for removal of the sources of asbestos identified Asbestos sources can be harmful for the environment and for people working or living in the building. In general, asbestos sources can stay in the building as long as the asbestos fibers are bounded in the material, which is the case in cement plates for example. As long as those materials are not damaged, there is no actual risk for inhaling fibers. Asbestos sources in which the asbestos sources are not securely bounded can bring an actual risk, for example in pipe insulation and sprayed asbestos against steel structures. In the table below, a division is made in asbestos sources that have to be removed because of an actual risk and asbestos sources that can safely be present in the buildings until renovation (maintenance) or demolition of the building. The table below indicates which removal methods are recommended for each asbestos source. However, it should be noted that this recommendation is in no way binding. The certified asbestos remediation officer may deviate from the recommendations. source/id description removal risk-level 1/67526 sealant outside remediation low: removal only in case of renovation or demolition 2/67527 sealant outside remediation low: removal only in case of renovation or demolition 3/67528 sealant outside remediation low: removal only in case of renovation or demolition 4/67529 sealant outside remediation low: removal only in case of renovation or demolition 5/67530 sealant outside remediation low: removal only in case of renovation or demolition 6/67531 sealant outside remediation low: removal only in case of renovation or demolition 7/67532 sealant outside remediation low: removal only in case of renovation or demolition 8/67533 sealant outside remediation low: removal only in case of renovation or demolition 12/67537 sealant outside remediation low: removal only in case of renovation or demolition 13/67538 sealant outside remediation low: removal only in case of renovation or demolition 14/67539 sealant outside remediation low: removal only in case of renovation or demolition project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 43

53 5. Safety and health 5.1 Asbestos and health risks Asbestos fibers are harmful to human health. The asbestos fibers can penetrate the human body through the mouth, stomach and intestines, via the skin and the airways. Research has shown that asbestos fibers that have penetrated the body can have harmful effects. The risk of asbestos-related disease, however, is greatest if asbestos fibers are inhaled. For the human body, the inhalation of asbestos fibers may have consequences for health. The dimensions of the asbestos fibers will have a major influence on the health risks. Asbestos fibers with a length of more than 5 µm, a diameter of less than 3 µm and a length / width ratio of greater 3 : 1 are the most harmful. Due to their microscopically-small dimensions, these fibers are invisible to the naked eye, so that they are inhaled, unnoticed. A large proportion of the inhaled harmful asbestos fibers, which enter the lungs, cannot be removed by the lungs. These fibers remain behind in the lungs, and once there, can exercise their harmful influence in a number of ways. The symptoms do not emerge immediately, but often are only noticed years later. Harmful asbestos fibers which have penetrated the body can cause three diseases: asbestos-related lung cancer, asbestosis and Mesothelioma. All of these diseases can only be contracted by inhaling fibers. asbestos-related lung cancer: The harmful fibers can damage the lung cells in the alveoli. These damaged cells can disrupt the multiplication process in the cells. The result can be uncontrolled growth, which is known as lung cancer. Asbestos-related lung cancer can be caused by any type of asbestos, and may also occur following limited exposure to asbestos fibers. The combination of smoking and exposure to asbestos reveals a far greater risk of lung cancer than asbestos or smoking, individually. Generally speaking, the period between exposure to asbestos and the occurrence of lung cancer is longer than 10 years. Mesothelioma: Organs such as the lungs and the heart are surrounded by a membrane that as it were forms a sort of bag around the organ. As a result, the organ can move without hindrance from other parts of the body. Asbestos fibers that have penetrated through the lungs or intestines can damage the cells of the chest or stomach membrane. The damaged cells can lead to malignant uncontrolled cell growth in these membranes. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 45

54 Mesothelioma can be caused after a very brief exposure to small concentrations of asbestos dust. The more regular the exposure, and the greater the fiber concentrations, the greater the risk of occurrence of Mesothelioma. Mesothelioma can only occur due to exposure to asbestos fibers, in particular crocidolite and amosite fibers. The period between exposure to asbestos and the occurrence of Mesothelioma can vary from between 10 and 60 years. Mesothelioma is incurable. Once the syndrome has been identified, life expectancy is between 6 months and 2 years. Asbestosis: Asbestosis can be caused by exposure to very high concentrations of asbestos fibers. As a result of large quantities of asbestos in the lungs, lung capacity is reduced. Asbestosis is one of the group of pulmonary diseases. The reduction in lung capacity means that the heart is required to pump ever faster to deliver oxygen to the rest of the body. Over time, the heart will become overburdened, due to insufficient capacity. Asbestosis can occur between 10 and 30 years following exposure to asbestos fibers, and is incurable. 5.2 Calamities Before or during the dismantling or renovation work, calamities or disasters may occur whereby large asbestos fiber emissions take place. For example, as a result of fire or collapse, asbestos sources present in the object can be damaged in such a way that the result is contamination. In these cases, it is vital that the emission of asbestos fibers to the environment and human exposure to asbestos fibers be kept to a minimum. People without personal protective equipment and breathing apparatus should remain as far as possible from the source of asbestos. In the event of disasters, the following bodies should be immediately contacted: municipal authorities, police, health and safety at work inspectorate, health and safety at work service and environmental hygiene inspectorate. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 46

In the table, a division is made in asbestos sources that have to be removed because of an actual risk and asbestos sources that can safely be present in the building until renovation (maintenance) or demolition of the building. Sources with a low risk cause no risks for the health as long the sources do not get damaged (sawed, drilled, screwed). The locations of these materials have been marked on the floor plan(s) in the appendices. Certificates of samples analyzed have been included in the appendices. The recommendations for the methods of removing these asbestos-containing materials are contained in chapter four. Ingenieursbureau Oesterbaai b.v. aimed for the fullest possible detection and registration of asbestoscontaining materials, during the survey, in accordance with the BRL 5052 standard. Nonetheless, we recommend that potential contractors for the asbestos removal work have a survey made of the remediation location, so that they themselves can obtain an impression of the situation, in situ. We would point out the obligation of having asbestos removal work carried out by a company certified in accordance with the National Assessment Directive 5050, and in possession of the KOMO BRL 5050 certificate. Following remediation, it may be required in law to have an independent RvAaccredited laboratory carry out a release (measurement) in order to check the work of the remediation company, and to determine whether the remediated area(s) can once again be safely entered. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 48

57 Under all circumstances, it is advisable to call in an independent laboratory, once the work has been completed. It may also be worthwhile, during the asbestos removal work, to have an independent laboratory or consultancy firm supervise the project (progress and safety), and inspect the asbestos removal work. Total project supervision from planning, appointment of remediating company right through to release is another option worth considering. Ingenieursbureau Oesterbaai b.v. would be pleased to offer its services in any subsequent phases of the project. project number: PAI-12765, Full asbestos survey, facades Building B, C, D & E, ESA (ESTEC) Noordwijk (v1.0) page 49
