CHANGES IN PRACTICE
As has been indicated, there is a probability of the demand for asbestos increasing. The wide use of motor-transport equipment demands a large amount of high-grade fiber for brake linings, while the increasing use of steam equipment, and electrical equipment and appliances, demands more and more material, both for electrical and heat-insulating purposes. Although substitutes may be employed for the lower grades, no substitutes are known for the spinning grades of asbestos, which are now in strongest demand. Consequently there are no changes in practice that will reduce the demand for asbestos.
