Persons exposed to this material should use adequate protective devices as inhalation of this material over long periods may be harmful." The label is intended to remind all industrial users of asbestos that proper handling will contribute to improved conditions in work areas. Physical protection for employees is provided through the use of safety hats, shoes, glasses, and other devices when circumstances warrant. Health protection is just as important and should include appropriate practices and equipment such as collectors, ventilators, masks, etc., to prevent inhalation of fumes and particulate matter. As you know, in the past several years there has been increasing publicity and medical attention given to health effects of inhaling industrial dust and fumes of all kinds. Some studies have raised the question whether adequate control measures are being taken in certain . industrial operations to prevent the inhalation of asbestos particles. Other studies have shown that where proper protective measures are taken, occupational health risks are minimized. / continued .... -2- Medical research on health questions relating to asbestos is being sponsored by Johns-Manvilla, the Quebec Asbestos Mining Association, and several other organizations. Such research will lead to a better understanding and control of health hazards associated with inhalation of -- asbestos particles. Until more concrete information is available from the abovementioned research, we have concluded that it is in the best interest of all concerned that we place the above label on bags containing asbestos to encourage careful handling of the fibre. If you have any questions, we would be pleased to hear from you. - - i ' i NWH / oh Yours very truly. N. W. HENDRY, General Sales Manager. -:,r? 0037 1 * ---------- >
