We wish to relived readers ot two unoortant coin's First, m considering anv 1(.`commendations in the AIA publication ; the ,e should tie m uted to the specific legal requirements in trie country concerned It is clearly not possible in such publications to relate the mcominondations in e v n y respect to the specific detailed regulations in each state Nevertheless, the greater part ot oosiing law ; on the subject calls lor .miller loim s ot control and when! no ulliciu! regulation exists we advise that acdon should be based on the (.commendation ol the ILO meetings ol experts on the sale use ol asbestos, in December 1973 and October 1981. Secondly, the development of techniques ol control is a continuous process, and we hope that the efforts we are undertaking will help to accelerate the process Tecnniques which are recommended have reached their present stage as a result of interchange of ideas and practical experience between international experts in the asbestos industry, plant manufacturers, government agencies and many others. It will certainly be necessary regularly to up-date and amend these publications in the light of new ideas and criticisms. All such will be welcomed and will be given full consideration during revision stages.

Waste Disposal 6.1 Loose swarf and dust collected from fabucation processes should be collected for disposal in a controlled manner and in accordance with regulations where these exist. Strong plastic bags are a suitable form of impermeable container (see RCP3) 6.2. Broken and worn linings will not normally produce harmful quantities of dust. However, to avoid unnecessary anxiety (and in some countries to comply with legal requirements), where such waste materials occur in quantity they should be collected and disposed of in a controlled manner, and in accordance with regulations where these exist (see RCP3). 7.
