How dangerous is this?
Work on any type of asbestos can be dangerous. However, tasks on these particular materials can be carried out by non-licensed workers who are appropriately trained. Maintenance and low risk work such as removal of gaskets or rope which can be removed virtually intact without substantial breakage would not normally be notifiable provided that the material is in good condition.
