Cal. Health and Safety Code § 19810

(a) “Article” as used in this chapter means and includes any article of wearing apparel, cloth, drapery or other fabric or material made from or containing any natural or synthetic fiber. (b) “Vendor” as used in this chapter means any individual, firm or corporation engaged in the manufacture for sale or the sale of articles as herein defined. (c) “Inflammable article” as used in this chapter is any article made from or containing natural or synthetic fiber and determined by the Fire Marshal to be so highly inflammable as to constitute a dangerous risk of fire and hazard of injury to persons and property, taking into consideration the use or uses for which the article is made and designed to serve. (d) It has recently come to notice that of the various natural or synthetic fibers adapted and adaptable for use in the making of articles, as herein defined, some are so inflammable as to constitute a dangerous risk of fire and hazard of injury to persons and property. Provision should be made for the avoidance of such risks and hazards by preventing the use of such highly inflammable fibers. It is not feasible by statute to prescribe more specific tests than those herein prescribed, for it would appear that none such have yet been fully developed. It is necessary, therefore, to commit to the State Fire Marshal the conduct of research in these matters, the development of tests for these materials, and the administration of the provisions of this chapter for the prevention of the risks and the avoidance of the hazards described.
