RMS-LB 2018 with 12/20 Revisions

General Practices 5 ANSI/AARST RMS-LB 2018 (with 1220 revisions) Radon Mitigation Standards for Schools and Large Buildings b) Ventilation Whenever application of sealants, caulks, or bonding agents that warrant ventilation of work areas is anticipated. For this situation, the contractor shall request that the client(s) provide notices to occupants that include the following text or equivalent: 4.3.3 Occupant sealant advisories Informative advisory —It is recommended that the contractor post or leave notices for affected occupants that include the notice text provided in Section 4.4.2.b when using sealants. (See example in Exhibit B .) 4.3.4 Material safety data sheets (SDS) The contractor shall provide the client upon request the published safety data sheets for materials used. 4.4 Jurisdictional Authorities 4.4.1 Local jurisdictions (radon) The contractor shall notify the client of any reporting requirements published by the state or local jurisdiction where the mitigation is being performed. Information to locate State Radon Offices in the U.S. can be found at www.epa.gov/radon/find-information-about-local-radon-zones-and-state-contact-information#stateradon . 4.4.2 Building codes All components of the mitigation work shall be in compliance with the applicablemechanical, electrical, building, plumbing, energy and fire prevention codes, or any other regulations of the jurisdiction where the work is performed. Note—For localities having no relevant code requirements, the most recent version of nationally published codes should be observed to help assure safety of occupants and building integrity. 4.4.3 Licenses and permits required by local ordinances shall be obtained. 5.0 SYSTEM DESIGN 5.1 Health and Safety Mitigation systems shall be designed and installed to avoid the creation of health or safety hazards. 5.2 Long-Term Considerations The design and resulting operations, maintenance, and monitoring plan (OM&M) shall, to the extent practicable, include consideration for facilitating and easing the client’s ability to achieve the client's goal of long-term risk management. 5.3 Appropriate Systems Appropriate design features shall be considered, such as: a) Practicality Observance that controlling pollutants at their source rather than after entry to the indoors becomes more important as buildings are designed or retrofitted to be more energy efficient; “ Occupant Advisory: Common construction sealants used to prevent radon entry at foundations and other locations will normally emit vapors that contain modest amounts of certain chemicals generally referred to as volatile organic compounds. The emissions occur mostly during application, but also to a lesser extent as they dry to form an airtight bond. While these chemicals are commonly used, some sensitive individuals may experience discomfort or other health effects when exposed to such chemicals. Symptoms that may indicate sensitivity to these vapors may include: nausea, headaches, dizziness, drowsiness and/or an allergic reaction. Special consideration should be made for the very young or elderly who cannot communicate symptoms experienced. Safety Data Sheets (SDS) are available upon request. If symptoms are observed: Leave the area immediately to breathe fresh air. Avoid further exposure. If symptoms persist, get medical attention.” (See notice examples in Exhibits A-1 and A-3 .) The notification to clients regarding hazardous materials shall include: a general description of the hazardous materials; symptoms that might indicate sensitivity to the materials; and actions to take if symptoms are observed.
