You really don't need to worry about this for lanterns that are post 1970. White asbestos was used, but never in Philips lanterns, especially your Mi26. Your Beta 5 should also be safe.
This image is what you need to avoid.
But not to be confused with the sleeving shown here, which is fibre glass and perfectly safe - although could cause skin irritation.
The danger is from inhaling fibres, but in wiring insulation its usually tightly woven.
Fibre glass will be in the form of a (removeable) sleeve, or occasionally as the main insulation (aircraft wiring can use a similar material), asbestos will always be in the form of the main insulation, never in in the form of a removeable over sleeve.
