Asbestos Regulations Royal Navy and HM Dockyards (1969)

This document is not a research study. It is an asbestos safety instruction, catalogued as coming from the HM Dockyard Medical Research Team (April 1969). It covered personnel and contractors' employees in HM Ships and Ministry of Defence premises, and it reported no measurements or health findings. It stated that crocidolite and amosite use had been discontinued, that trials would likely reduce chrysotile use, and that hazardous materials would remain in service for some time. Asbestos tasks, such as removing sprayed limpet asbestos, lagging and de-lagging, were classified. Registered asbestos workers were to be examined, including a full plate x-ray, before registration. After that they were to be examined annually, with chest x-ray, while they remained in Ministry of Defence (Navy) employment, even after leaving asbestos work. No one under 18 was to do asbestos work. The instruction recommended exhaust ventilation where possible, led through filters retaining particles down to 0.5 micron. Debris was to be bagged and either dumped at sea, ensuring the sacks sank, or buried on municipal tips after warning the authorities. Dust sampling results were to be compared with standards in the Asbestos Regulations 1968.
