Otherwise, participation in OM&M is typically stipulated in extensive detail under a separate agreement. 4.3 Notification and Hazards 4.3.1 Ventilation The client shall be informed, prior to starting work, of the need to ventilate work areas during and after the use of sealants, caulks or bonding chemicals containing volatile solvents.
