Health and Safety 48 ANSI/AARST RMS-LB 2018 (with 1220 revisions) Radon Mitigation Standards for Schools and Large Buildings 11.1.4.2 Work Area Contaminants In any planned work area where it is suspected contaminants such as asbestos, lead paint, mold or other toxins may exist, work shall be conducted in a manner that meets applicable regulations and maintains consideration for the health and safety of both workers and occupants. 11.1.4.3 Material Safety Data Sheets (MSDS) Each mitigation installer shall be provided with the applicable Material Safety Data Sheets (MSDS) for all hazardous materials used and be informed of the safety procedures required for each. 11.1.4.4 Ventilation Work areas shall be ventilated when practical to reduce a mitigation installer’s exposure to radon , radon decay products, dust, sealant vapors or other airborne pollutants. 11.2 Both Workers and Occupants (General Precautions) 11.2.1 Job site hazards Informative advisory —The contractor should take precautions to protect from jobsite hazards. Where appropriate, the contractor should post or provide notices, restrict access to job site areas or cease work until safe conditions can be secured. Where appropriate: a) A review of existing documents and action plans regarding hazardous conditions should be conducted prior to diagnostics or initiation of an installation; b) Prior to diagnostics or during installation, it is sometimes appropriate that utility line locations be identified in the immediate areas where drilling through slabs will occur. Care should be taken to recognize that design drawings do not always represent actual installations or retrofit installations; c) When concerns arise for contaminants prior to or during installations, such as for chemical or waste pollutants in soil, the contractor should request confirmation testing or removal of contaminants; and d) When confined areas are determined to be hazardous working environments, the contractor should seek safe alternatives, such as altering system(s) design or creating safe means of egress to the confined area. 11.2.2 Flue gas spillage Altering pressure in the building, directly or indirectly, may cause flue gas spillage . Clients and impacted residents shall be advised of any significant flue gas spillage that is observed. If flue gas spillage is observed to result from the mitigation system operation, the system shall be deactivated until the condition has been evaluated and corrected. In such event, the client shall be advised to contact an HVAC contractor or other qualified person to evaluate and correct any significant flue gas spillage condition as well as to verify proper appliance installation and performance. Note—In addition, the client should be directed to sources of additional information such as those found at: • www . cpsc . gov / cpscpub / pubs /466. html • www . epa . gov /i aq / homes / hip - combustion . html • Appendix D of the International Fuel and Gas Code (as published by the International Code Council). 11.2.3 Asbestos Note—Deteriorating, damaged or disturbed products containing asbestos can pose a serious health threat to occupants and workers. Asbestos-containing materials can include materials for insulation, fireproofing, acoustical materials and floor tiles. Asbestos inspection reports, if even in existence, do not always specify the location of asbestos and previously hidden asbestos-containing materials which can be exposed during construction or renovations. 11.2.3.1 In any planned work area where it is suspected that asbestos may exist and be disturbed, work shall not be conducted until an accredited asbestos inspector that is licensed by the state or local jurisdiction, where applicable, determines that such work will be undertaken in a manner that complies with applicable asbestos regulations. Informative advisory—The client should be notified that proper assessment and abatement procedures are to be followed as regulated by NESHAP, OSHA, the LSHR and state and local regulations for the protection of the health and safety of occupants, and contractors .
