On a plan drawn at 1/2 inch = 1 foot, a wall measures 7-1/4 inches. How long is the wall?
Why: At 1/2 inch = 1 foot each inch of paper is 2 feet, so 7.25 × 2 = 14.5 feet. Twenty-nine feet is the result at the 1/4-inch scale, 58 feet the result at the 1/8-inch scale, and 7-1/4 feet ignores the scale entirely.Armstrong F-5061 Ch. 11 (blueprint scales)
Under Cal/OSHA section 1529, removing asbestos-containing floor tile and construction mastic is which class of asbestos work?
Why: Class II covers removal of asbestos-containing material other than thermal system insulation or surfacing, expressly including floor tile, sheeting and construction mastics. Class I is removal of thermal system insulation and surfacing material. Class III is repair and maintenance where material is likely disturbed. Class IV is maintenance and custodial contact without disturbance.Cal. Code Regs., tit. 8, §1529(b)
