Presentation on theme: "Ready to demolish a building"— Presentation transcript:
1 Ready to demolish a building Ready to demolish a building? For safety’s sake, take out hazardous wastes first!START by using this brief tutorial to find what you need on this web site
2 Prior to Demolition… One Needs to Seek Out Hazardous Materials To ensure worker and occupant safetyTo comply with local, state, and federal regulationsTo avoid future liabilityTo protect the environment
3 What are the environmental impacts we are trying to avoid? There are chemicals and materials that MUST stay out of standard landfillsTo avoid chemical reactions or explosions in the landfillsTo avoid future leaching of these or other chemicals from the landfillsTo comply with state and federal laws
4 What are the environmental impacts we are trying to avoid? Further, if not first removed from the jobsite, hazardous materials, pieces and particles can be released during demolition onto the ground and mobilized by wind or storm runoffWhen it rains, stormwater flows to the local creek and then to San Francisco BayThere are chemicals and materials that need to stay out off of the land and out of the waterways
5 Building owners, managers, contractors, and DIYers need to know: Where to find these materialsHow to identify themPossible hazards to building occupants, demolition staff, and the environmentPossible liabilities if ignoredWhat to do with these materials when they find themHOWEVER… the correct answer varies WIDELY from one hazardous material to the next!
6 Thus a brochure and web page were developed to lead to the answers
7 Many reviewers have assisted in assuring the accuracy of the information:
8 First, you can use the brochure as a quick checklist to remind yourself and others of the hazards you should be looking for:
9 To help speed up the inspection, the checklist has been split into two parts
10 First, a list of hazards that may be at any building
11 Second, a list of hazards that are only expected at buildings built or remodeled prior to 1980
12 The brochure fold-over is tied to both lists, using photos to help you know what to look for.
13 So, the brochure helps you identify the specific health hazards…
14 …while the detailed answers for hazard management and disposal are on this companion web site:
15 Let’s take a look through the web site Go toWhen you click on “Step 1,” you will see a long list towards the bottom of that page
16 It looks a bit ominous at first, but again, it has been organized to help you out
17 We have divided the insights by the building type and age Structures of any ageIndustrial and institutional structuresStructures built or remodeled before 1980
18 1. Structures of Any Age:Chemically treated wood (arsenic, chromium, copper, creosote, and/or pentachlorophenol)Pressure-treated dimensional lumberCreosote-treated railroad ties (outdoor landscaping)CCA (chromated copper arsenate)-treated wood
19 1. Structures of Any Age: Ceilings and floors (asbestos) Textured ceilingsCeiling panels and tilesResilient flooring – vinyl floor tiles and backing on vinyl or linoleum sheet flooringMastic adhesive
20 1. Structures of Any Age: Insulation (asbestos) Cement-based insulation (sheets, shingles, and pipes)Furnace, water heater, and heating duct blanket or tape insulationRoofing shingles and mastic (asbestos)Photo from EPA: Vermiculite insulation in an attic
21 1. Structures of Any Age: Light bulbs and lamps (mercury) Fluorescent tubes and bulbsHigh-intensity discharge (HID) bulbsNeon tube signs and lampsLight ballasts (PCBs or DEHP)PCB ballast from an old fluorescent overhead lamp
22 1. Structures of Any Age: Wall thermostats (mercury) Smoke detectors (radioactivity)Glow-in-the-dark EXIT signs (radioactivity)
23 2. Industrial or institutional structures have additional considerations: Industrial electrical switches and relays (mercury)
24 2. Industrial or institutional structures have additional considerations: Industrial electrical switches and relays (mercury)Medical/dental/veterinary (mercury)Medical/dental equipmentLaboratory fume hoodsSewer linesAdd photos
25 2. Industrial or institutional structures have additional considerations: Industrial electrical switches and relays (mercury)Medical/dental/veterinary (mercury)Medical/dental equipmentLaboratory fume hoodsSewer linesSchools (mercury)Gym flooringAdd photos
26 3. Structures built or remodeled prior to 1980 may also contain: Paint (lead)Galbestos – an asbestos cement board – 1944 ad “Prewar Tested for Postwar Roofs”
27 3. Structures built or remodeled prior to 1980 may also contain: Paint (lead)Electrical transformers and capacitors (PCBs)Galbestos – an asbestos cement board – 1944 ad “Prewar Tested for Postwar Roofs”
28 3. Structures built or remodeled prior to 1980 may also contain: Paint (lead)Electrical transformers and capacitors (PCBs)Caulk and sealants (PCBs)Galbestos – an asbestos cement board – 1944 ad “Prewar Tested for Postwar Roofs”
29 3. Structures built or remodeled prior to 1980 may also contain: Industrial or institutional materials (PCBs)Paint (lead)Electrical transformers and capacitors (PCBs)Caulk and sealants (PCBs)AdhesivesInsulationApplied dried paints, coatings, or sealantsMolded rubber partsPaintFelt or fabric products such as gasketsPlasticsSound-deadening materialsGalbestosGalbestos – an asbestos cement board – 1944 ad “Prewar Tested for Postwar Roofs”
30 Each subject-link provides information about hazard management and disposal. Next are a few examples:
34 Some topics (such as lead paint, asbestos, and PCB-containing materials) have extensive insights about where to find the material and what steps to take:
35 Asbestos (cont’d)Some topics (such as lead paint, asbestos, and PCB-containing materials) have extensive insights about where to find the material and what steps to take.
36 The bulk of specifics are on those pages. Steps 2 and 3 provide some follow-up insights
37 Step 3 is about disposal… Let’s dig a little deeper
38 Transport and Disposal Transport and disposal of hazardous waste is regulated by EPA and DTSCTransporter must hold a valid registration issued by DTSCA current list of registered hazardous waste transporters is available in the Registered Hazardous Waste Transporter Database at:
39 Transport and Disposal The generator of the hazardous waste is responsible for and required to dispose of all hazardous wastes in accordance with Federal and State waste disposal regulationsPermitted hazardous waste facilities are contained in DTSC’s Envirostor database at:
40 Transport and Disposal Wastes generated during the project may include:The originally identified hazardous materialSolid waste generated as part of clean up processLiquid waste generated as part of clean up process
42 Prior to Demolition, Step 1 is identification… Check All BuildingsChemically treated woodAsbestos-containing materialMercury-containing fixtures and equipmentParticularly institutional and industrial structuresLight ballastsExit signsSmoke detectorsAdditional Issues for Buildings Built Prior to 1980Lead paintPCBs in electrical equipmentPCBs in caulk, sealants, and other materials
43 Then… Step 2: protect yourself, staff, and building occupants Step 3: comply with state and federal transportation and disposal laws
