【国外标准】 Standard Practice for Preparing an Occupant Exposure Screening Report (OESR) for Substances in Installed Building Products

4.1 This practice is applicable to all interior and exterior installed building products in the use phase of the product, specifically in the form present in the occupied building. This practice does not cover products during installation processes since those exposures are covered by occupational regulations.4.2 This practice specifies the required information to include in the OESR screening report for product decision makers to assess the potential for occupant health exposure from installed building products in an occupied building operated under normal and anticipated conditions of use.4.3 Fundamental to the selection and use of building products is the consideration of the likelihood of occupant exposure and possible risk to substances in those installed building products.4.4 This practice does not purport to offer full risk information, nor does it purport to be equivalent to an exposure or risk assessment. Rather, it provides screening to inform the product decision maker about conditions that could generate additional discussions with manufacturers or others.4.5 The informational requirements for an OESR are identified in Section 5.4.6 For substances with hazard classifications in 5.3, the OESR informs product decision makers about substances in an installed building product that might trigger a hazard warning to a user or building occupant. This information is designed to help the product decision maker determine whether added information is needed to evaluate exposure and risk more fully in the context of the installed building product’s specific use or application.4.7 The OESR screening report is required to be updated based on the requirements in 9.3.4.8 The OESR is completed by last manufacturer of the building product; this is the manufacturer offering the external or internal building product to the market. This manufacturer may need to obtain information from other manufacturers in its supply chain.NOTE 1: The manufacturer offering the building product to the market is aware of the form, function, and likely uses of the building product under normal conditions of use. If the product contains hazardous substance(s), it is likely that the manufacturer has information about the hazards from the product under foreseeable emergencies in compliance with OSHA requirements.1.1 This practice provides the information required for publishing a screening report for occupant exposure from substances in installed building products (OESR) to communicate possible human health impacts in an occupied building to product specifiers, building owners, and others.1.2 This practice is applicable to all interior and exterior building products in the form used and incorporated into an occupied building.1.3 An article going into the construction market that has potential hazards based upon an evaluation of the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) (1)2 mixtures guidance is included in the scope of this practice.1.4 This practice does not cover product fabrication or installation processes because these are subject to worker safety and health regulations and law.1.5 The final building product manufacturer offering the building product to the market or agent is responsible for providing this information and completing this report.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
