Asbestos removal by wet blasting

Asbestos is a set of naturally occurring silicate minerals that have long been used in the manufacture of heat and acid-resistant products, especially in the construction, insulation, automotive and shipping industries.

Since the 1980s and 1990s, the trade and use of asbestos has been banned in an increasing number of countries due to the high health risks. Building owners today are obliged to find out about the presence of asbestos and to ensure it before it decays and to remove it if necessary.

Wet blasting process: the last resort to remove asbestos

Asbestos-containing materials (ACMs) are usually removed using low-dust methods such as wet grouting, spraying, and manually. The aim is to minimize worker exposure and prevent the spread of dust. However, in some exceptional cases it may be necessary to use more abrasive when removing ACMs. Radiation should only be viewed as an emergency solution in exceptional cases. The use of the procedure must be legitimized by a licensed contractor.

Consider the risks of removal

Usually the customer pushes for asbestos blasting. Most people want a building that is asbestos-free at all costs. As a contractor, you need to involve the customer in the decision-making process and explain the additional risks of asbestos removal. Together, you should consider whether the reasons for removing justify these risks.

Measures to remove asbestos by wet blasting

To minimize the dangers of removing asbestos using wet blasting methods, you should take the following control and safety measures:

· Plan the work carefully and make sure that no other tasks are being carried out at this time.
· Set up clear blasting processes and workflows. Define the maximum pressure level and moisture content.
· Carry out regular cleaning with suitable cleaning equipment.
Equip everyone involved in the blasting process with appropriate personal protective equipment (PPE):
o Air-fed respirator (RPE) with dust filter
o hearing protection
o Face protection
o Protective suits
o gloves
o Protective work shoes
· Reduce the noise level to a minimum.
· Distribute the tasks evenly in order to limit manual handling and vibration exposure.
· Protect sensitive installations and electronics in the room from water vapor.

Conclusion

The removal of asbestos with the wet blasting method is only possible under certain conditions. Contractors and customers should decide together whether the use of wet blasting methods is desirable. If so, appropriate security and control measures should be taken. Contact our specialists if you have any questions about the wet blasting process and the removal of asbestos.
