Remember that all asbestos is dangerous, the difference between white, blue and brown is not really a significant issue as it can take just one asbestos fibre to cause problems.
Yes blue and brown have more spiky fibers and so have more chance of getting caught in the lungs than being expelled but any fiber could lodge in the lungs.
That said the risk from undisturbed asbestos is minimal, the flash guards being a case in point.
To remove them would generate far more risk than leaving them in place.
Any reasonable risk assessment would include procedures for not disturbing the flash guard in normal use but should not recommend removal unless the equipment is being decommissioned.
Sorry, but there ''IS'' a significant difference in the types of asbestos related to death and disease. If you have attended one of these Asbestos Awareness courses, they make that aspect very clear.
