Shock Mounting of Mechanical Equipment. All permanent mechanical equipment such as motors, compressors, pumps and compactors which, because of their rotation, reciprocation, expansion and/or contraction, turbulence, oscillation, pulsation, impaction or detonation, are determined by the Chief Building Inspector to be a source of structural vibration or structure-borne noise shall be shock mounted with inertia blocks or bases and/or bases and/or vibration isolators in a manner approved by the Chief Building Inspector. Domestic appliances which are cabinet installed or built into the individual units, such as clothes washers and dryers, or other appliances which are determined by the Chief Building Inspector to be a source of structural vibration or structural-borne noise, shall be isolated from cabinets and floor or ceiling by resilient gaskets and vibration mounts approved by the Chief Building Inspector. The cabinets in which they are installed should be offset from the back wall with strip gasketing of felt, cork or similar material approved by the Chief Building Inspector. Where such appliances utilize water, flexible connectors shall be installed on all waterlines. If provision is made within the units for the installation of nonpermanent appliances such as clothes washers and dryers, then permanent rubber mounting bases and surface plates shall be installed in a manner approved by the Chief Building Inspector.
