Abstract
A method is described for encapsulation of hazardous substances, in which very small particles of the substance are sandwiched inside a matrix of an inocuous substance, such as plastic or rubber. This encapsulation greatly reduces worker exposure to dangerous materials. Lead (7439921), lead-oxide (1309600), sulfur (7704349), antimony (7440360) and ethylene-thiourea (96457) are presently available in encapsulated form. Limitations of encapsulation depend on interference of the plastic matrix with the final product, the ease of encapsulation, and interactions of the dispersant and the matrix. The author suggests that the use of encapsulation to reduce hazards will increase in the future.
