Handling Hazardous Building Materials: How to Avoid a Construction Nightmare


Published on

Is your organization planning a renovation or expansion? Maybe you'd like to conduct building maintenance to prevent a future emergency? There are multiple hazards and toxins that need to be taken into consideration before starting a construction project. If hazards are not properly identified, tested and removed, they have the potential to derail a project. This presentation will show you how to handle hazardous building materials from the perspective of two environmental engineers.

  14. 14. 14 Asbestos Sampling • Miscellaneous Materials  At least one sample shall be collected from each suspected miscellaneous material. (EPA)  OSHA says: In a manner sufficient to determine whether material is ACM or not ACM, collect bulk samples from each homogeneous area of friable miscellaneous material that is not assumed to be ACM.
  15. 15. 15 Definitions • The US EPA defines ACM as material containing >1% asbestos. • MA DEP has requirements for asbestos containing waste material (ACWM) for specific materials (vermiculite) containing 1% asbestos or less.  Non-routine asbestos abatement work
  16. 16. 16 It’s Identified, Now What? • Abatement  Performed by licensed contractor  Requires 10 working day notification to the state  Clearance sampling  Re-occupancy • Management  Asbestos Management Plan or O&M Plan  Asbestos awareness training
  17. 17. 17 Case Study • Facility wide asbestos inspection and management plan • 12 buildings assessed, one for pre-demolition and the others for an O&M plan • Over 300 samples collected over the course of 6 business days • Asbestos identified in roofing materials, TSI, mastic, floor tiles, fume hood panels, etc. • Continues management and inspection of areas identified

  42. 42. Agenda 42 Asbestos Lead Polychlorinated Biphenyls Mercury (in plumbing) Summary & Questions
  43. 43. What is Mercury? • Naturally occurring element that in its pure form is a liquid that volatizes readily • Exposure at high levels can harm the brain, heart, kidneys, lungs, and immune systems • Mercury vapor is colorless and odorless
  44. 44. Where Can It Be Found? Thermometers Barometers Manometers Light bulbs Thermostats Coal and other rocks Coal-burning power plants are the largest human-caused source of mercury emissions to the air in the United States
  45. 45. Mercury Devices in Your Facility
  46. 46. 46 Mercury in Plumbing • Relic plumbing  Mercury poured into drains can remain in the plumbing indefinitely, until it is physically removed or the plumbing is replaced • Often overlooked • Mercury remediation is costly and time consuming
  47. 47. Mercury in Plumbing
  48. 48. Mercury Vapor Measurement • Various methods are used to detect and quantify mercury vapors in air • Vapor detection limits vary significantly • Regulations and guidance concentrations can be in milligrams per cubic meter (mg/m3), micrograms per cubic meter (ug/m3), or nanograms per cubic meter (ng/m3)
  49. 49. 49 Mercury Vapor Measurement
  50. 50. Mercury Vapor Measurement Triumvirate utilizes the Jerome J-505 for most mercury vapor monitoring activities. Monitoring Device Detection Limit Dräger tubes 0.05 mg/m3 Jerome J-505 0.00005 mg/m3 Lab (EPA Method 6009) 0.002 mg/m3 Lumex 0.00005 mg/m3 Jerome 431-X 0.003 mg/m3 (± 0.003 mg/m3) X-Ray Fluorescence (XRF) Analyzer 10 to 20 mg/kg 48
  51. 51. Mercury Meter Interferences • Potential interferences to the Jerome 431-X mercury vapor analyzer have been identified and are listed in the Manufactures Owners Manual • Erroneously high readings can sometimes occur with the presence of:  Hydrocarbons  High levels of CO, CO2, and SO2  Water vapor/condensation  Chlorine and Ammonia  NO2  Hydrogen Sulfide (H2S)  Most mercaptans (organic sulfur compounds or “thiols”) • There are no known interferences with the Jerome J505 or Lumex meters 49
  52. 52. Regulations and Guidance • OSHA established a PEL as a ceiling value of 0.1 mg/m3, the only legally enforceable federal U.S. standard • NIOSH set a REL of 0.05 mg/m3 as a 10-hour, time weighted average • The ACGIH recommended the most recent occupational exposure standard as the TLV- TWA of 0.025 mg/m3 • The ATSDR recommends risk managers isolate humans from mercury spills when a concentration level of ≥ 0.01 mg/m3
  53. 53. 53 Cleanup Guidance
  54. 54. Worker Health and Safety Spills within a facility can pose a threat to worker health and safety and to building occupants: • Improper PPE • Cross Contamination • “Hot Spots” • Improper Clean Up • Improper Waste Disposal 52
  55. 55. Mercury Clean Up Products & Equipment Triumvirate utilizes multiple mercury cleanup products to effectively eliminate mercury vapor releases, including: • Mercury Vacuums • Mercury Amalgamation • Mercury Vapor Adsorption 53
  56. 56. Waste Disposal • The most common disposal method is mercury retort • Solid and liquid bearing wastes are put through a controlled high vacuum retort system that recycles mercury • The mercury can be recycled up to 99.99995% purity, and can be used on a wide variety of applications 54
  57. 57. Case Study: Mercury in Lab Piping
  58. 58. Case Study: Mercury in Lab Piping • Remove each sink trap, collect the contents, and screen with a Jerome J-505 • Traps with detections were removed and containerized for proper disposal • Remaining laboratory waste piping was screened, and any piping with detections was cut and containerized for proper disposal • All piping was removed until there were no detections on the Jerome 56
  59. 59. Agenda 59 Asbestos Lead Polychlorinated Biphenyls Mercury (in plumbing) Summary & Questions
  60. 60. Summary 60 • It is important to know what materials are present prior to construction or renovations to handle the building material/waste accordingly. • Pipes in your building may contain lead, mercury or asbestos. • It is important to assess a variety of building material to determine if they are hazardous. • Planning ahead will save you time and money during your renovations and construction projects.
