4. Halons contained in fire protection systems and fire extinguishers shall, during the maintenance or servicing of equipment or before the dismantling or disposal of equipment, be recovered for recycling or reclamation.
The destruction of halons shall be prohibited unless there is documented evidence that the purity of the recovered or recycled substance does not technically allow its reclamation and subsequent re-use. Undertakings destroying halons in such cases shall keep this documentation for at least 5 years. Such documentation shall be made available, upon request, to the competent authority of the Member State concerned or to the Commission.
