Asbestos

Company Purum Ltd. proceeds remediations in the field of asbestos removal from independent examination to complex treatment.

Survey and Assessment of Asbestos Presence

Materials containing asbestos often occur in specific building materials. Meaning that even by looking, skilled experts can presumably estimate the risk of its presence. Analysis with electron microscope, also determines positive or negative findings and is necessary prior to realization. Survey can be fragmented into:

1. Visual Examination without Sampling

Visual examination can suspend or confirm findings of suspicious materials including qualified recommendation of next proceedings.

2. Sampling and Analysis

Building construction is sampled and than analyzed. Technical scheme is made with sampling places and interpretation of findings. Estimation of quantity of asbestos materials is made when findings are positive.

3. Draft of Measures

After recognition of exact findings and elaboration of survey report it is common that skilled experts propose and expertly assess remediation urgency in view of risks of possible fiber release to the environment. In acute cases, measurement of quantitative respiratory fibers is made of inner environment.

Survey outcomes are documented and treatment elaboration is given on basis of risk assessment on a given location. Evaluation report shows defined necessary treatments and realization procedure.

Asbestos Remediation Realization

Purum Ltd. completes remediation itself in accordance with elaborated precaution on basis of experience with asbestos removal and survey findings. This process fulfills all legal enactments to ensure safety and health protection of employees including surroundings. Complex treatment including project elaboration, work with asbestos notice to relevant hygiene station and technological process is common.

With respect to all risks, all relevant rooms are secured to minimize outflow of asbestos to the environment and to buildings technological equipment. Dismounting and removal of all risk materials is carried out. Materials are then secured into special sealed bags prior to transport .

Subsequent Monitoring and Evaluation

Mechanical cleaning of decontaminated area is processed after remediation. Removal of all possible dusty elements which could contain asbestos fibers is completed. Remediation is followed by monitoring of atmosphere by special measuring device .

General Information about Asbestos

Asbestos is commercial name used for silicate minerals with ability to create long thin fibers. Those materials were proven as heat insulating and as part of constructions fire protection.

Main types of Asbestos are:

- group of serpentines – chryzotil (so-called white asbestos)

- group of amphiboles – amozit (so-called brown asbestos), krokydolit (sa-called blue asbestos), antofylit, tremolit, aktinolit

Asbestos fibers are resistive to high temperatures and chemicals and are electrically non-conductive. This is why they were so often used in various types of industry as building materials. These fibers tend to create fibrous dust in air and to cling to clothing. Once air-borne, these fibers are easily inhaled. Asbestos is carcinogenic agent. It evokes lungs fibrosis (so-called asbestosis), pleural disorder and malignant growth as are bronchogenic carcinoma and malignant mezotheliom. Long-term dormancy between exposition and disease breakout is characteristicall (about 15 to 40 years).
