Asbestos is a collection of natural silicate minerals that have been used for a long time in the production of heat and acid resistant products, especially in the construction, insulation, automotive, and shipbuilding industries. For years now, the sale and use of asbestos have been banned in an increasing number of countries due to its high health risks. Today, building owners are required to control asbestos in their facilities, be aware of its presence, and make sure that the material does not deteriorate. If necessary, removal of asbestos should be done. Blasting should only be considered as a last resort in some rare cases. The use of the procedure must be fully justified by a licensed asbestos removal contractor in Guildford.
- Asbestos properties:
· Weather-resistant material,
· Poor thermal, electrical, and noise conductivity,
· Relatively high tensile strength,
· Resistant to alkalis and most acids,
· A large specific surface area,
· Good adhesion to fittings;
· It is also a decorative material.
Due to these properties, this material was considered indispensable in several sectors of the economy. The industry uses mainly chrysotile asbestos, crocidolite asbestos, and amosite asbestos.
Asbestos has also been found in beverages prepared using asbestos filters or asbestos-contaminated water. An air sample is taken from the investigated place using an air sampling device to determine air pollution with asbestos. There are several types of air sampling devices, but most of them draw in the air (for example, using a vacuum pump) through a filter on which air pollution particles settle. The type of filter and the subsequent operation with it depends on the analysis method. For example, phase contrast microscopy uses membrane filters that are processed in acetone and triacetin vapors.
- Consider removal risks:
Usually, it is the client who initiates the abrasive treatment to remove asbestos. Most customers want the building to be asbestos-free, by whatever means are needed. As a contractor, you must involve the client in the decision-making process and explain the additional risks associated with asbestos removal. Together, you must consider whether the reasons for removing asbestos are worth the risks.
- Asbestos removal measures by waterjet:
- To minimize the hazards associated with water jetting asbestos removal, the following control and safety measures should be taken:
- Plan your work carefully and make sure no other tasks are running at the same time.
- Establish clear processes and work procedures for abrasive blasting. Set the maximum pressure levels and moisture content.
- Carry out regular cleaning with suitable cleaning equipment.
- Provide appropriate personal protective equipment to all those involved in the blasting process:
- Reduce the noise level as low as possible.
- Distribute tasks evenly to limit manual operation and vibration.
- Protect sensitive installations and electronics in the room from water vapour.
Removal of asbestos with water jet blasting is only possible under certain conditions. Contractors and customers should jointly decide if waterjet blasting is desirable. If a decision is made to use it, appropriate safety and control measures must be taken.
