Remove any accumulated dust before moving the printer into the area. Ventilation Ensure that the room in which the system is installed meets local environmental, health, and safety (EHS) guidelines and regulations. Fresh air ventilation is needed to maintain comfort levels. For a more prescriptive approach to adequate ventilation, you could refer as guidance to the latest edition of the ANSI/ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) document Ventilation for "Acceptable Indoor Air Quality". Adequate ventilation needs to be provided to ensure that potential airborne exposure is adequately controlled according to Safety Data Sheets. Consult the Safety Data Sheets available at http://www.hp.com/go/msds to identify chemical ingredients of your ink consumables. Airborne materials can be readily identified and quantified by using established indoor air quality testing protocols. HP performs these assessments during the development phase for all products. HP testing shows that during printer operation, the concentrations of airborne contaminants measured in the workspace are consistently well below key occupational exposure limits. This observation is based on exposure assessments that model very active productivity at customer facilities. Customers should recognize that actual levels in their facilities are dependent on workspace variables they control such as room size, ventilation performance and duration of equipment use. HP's assessment concluded, based on the available scientific information, that airborne materials are not expected to present a health hazard by providing a minimum of 10 ACH (air changes per hour) of fresh air ventilation and a minimum room volume of 80m³. These specifications are valid for the following conditions: one HP printer using a black area fill plot at around 40 m²/h, 10 passes and 150% of ink, assuming 6 hours of printing time a day. If there is a jumbo input/output unit, other equipment in the room or different conditions, the ventilation rate should be recalculated accordingly. In addition to the workspace benefit provided by general room ventilation, intense use of this printer system in some customers' facilities may necessitate the use of localized ventilation in order to provide a readily acceptable working environment. This installation of localized exhaust for a printer frequently enables the capture of airborne contaminants near their source of generation, and subsequently allows their efficient removal from the building through contained, and relatively low volume air flow. A workspace health and safety professional can provide guidance on the design and use of this auxiliary ventilation equipment. 14 Chapter 2 Site preparation ENWW
