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
Prior to Demolition… One Needs to
Seek Out Hazardous Materials
To ensure worker and occupant safety
To comply with local, state, and federal
regulations
To avoid future liability
To protect the environment
What are the environmental
impacts we are trying to avoid?
• There are chemicals and
materials that MUST stay
out of standard landfills
– To avoid chemical
reactions or explosions in
the landfills
– To avoid future leaching of
these or other chemicals
from the landfills
– To comply with state and
federal laws
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 runoff
• When it rains, stormwater flows
to the local creek and then to San
Francisco Bay
• There are chemicals and materials
that need to stay out off of the
land and out of the waterways
Building owners, managers,
contractors, and DIYers need to know:
Where to find these materials
How to identify them
Possible hazards to building occupants,
demolition staff, and the environment
Possible liabilities if ignored
What to do with these materials when they
find them
HOWEVER… the correct answer varies WIDELY
from one hazardous material to the next!
Thus a brochure and web page were
developed to lead to the answers
Many reviewers have assisted in assuring
the accuracy of the information:
First, you can use
the brochure as a
quick checklist to
remind yourself and
others of the
hazards you should
be looking for:
To help speed up the
inspection, the checklist has
been split into two parts
First, a list of hazards
that may be at any
building
Second, a list of
hazards that are only
expected at buildings
built or remodeled
prior to 1980
The brochure
fold-over is tied
to both lists,
using photos to
help you know
what to look for.
So, the brochure
helps you identify
the specific health
hazards…
…while the detailed answers for
hazard management and disposal are
on this companion web site:
Let’s take a look through the web site
• Go to www.baywise.org/demolition
– When you click on “Step 1,” you will see a long list
towards the bottom of that page
It looks a bit
ominous at first,
but again, it has
been organized to
help you out
We have divided the insights by the
building type and age
1. Structures of any age
2. Industrial and institutional structures
3. Structures built or remodeled before 1980
1. Structures of Any Age:
 Chemically treated wood (arsenic, chromium, copper,
creosote, and/or pentachlorophenol)
– Pressure-treated dimensional lumber
– Creosote-treated railroad ties (outdoor landscaping)
– CCA (chromated copper arsenate)-treated wood
1. Structures of Any Age:
 Ceilings and floors (asbestos)
– Textured ceilings
– Ceiling panels and tiles
– Resilient flooring – vinyl floor tiles and backing on vinyl or
linoleum sheet flooring
– Mastic adhesive
1. Structures of Any Age:
 Insulation (asbestos)
– Cement-based insulation (sheets, shingles,
and pipes)
– Furnace, water heater, and heating duct
blanket or tape insulation
 Roofing shingles and mastic (asbestos)
1. Structures of Any Age:
 Light bulbs and lamps (mercury)
– Fluorescent tubes and bulbs
– High-intensity discharge (HID) bulbs
– Neon tube signs and lamps
 Light ballasts (PCBs or DEHP)
PCB ballast from an old fluorescent overhead lamp
1. Structures of Any Age:
 Wall thermostats (mercury)
 Smoke detectors (radioactivity)
 Glow-in-the-dark EXIT signs (radioactivity)
2. Industrial or institutional structures
have additional considerations:
Industrial electrical switches
and relays (mercury)
2. Industrial or institutional structures
have additional considerations:
Industrial electrical switches
and relays (mercury)
Medical/dental/veterinary
(mercury)
– Medical/dental equipment
– Laboratory fume hoods
– Sewer lines
2. Industrial or institutional structures
have additional considerations:
Industrial electrical switches
and relays (mercury)
Medical/dental/veterinary
(mercury)
– Medical/dental equipment
– Laboratory fume hoods
– Sewer lines
Schools (mercury)
– Laboratory fume hoods
– Gym flooring
3. Structures built or remodeled prior
to 1980 may also contain:
Paint (lead)
3. Structures built or remodeled prior
to 1980 may also contain:
Paint (lead)
Electrical
transformers and
capacitors (PCBs)
3. Structures built or remodeled prior
to 1980 may also contain:
Paint (lead)
Electrical
transformers and
capacitors (PCBs)
Caulk and sealants
(PCBs)
3. Structures built or remodeled prior
to 1980 may also contain:
 Industrial or institutional
Paint (lead)
materials (PCBs)
Electrical
– Adhesives
– Insulation
transformers and
– Applied dried
– Molded rubber
paints, coatings,
parts
capacitors (PCBs)
or sealants
– Paint
– Felt or fabric
– Plastics
Caulk and sealants
products such as
– Sound-deadening
gaskets
(PCBs)
materials
– Galbestos
Each subject-link provides information
about hazard management and disposal.
Next are a few examples:
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:
Asbestos
(cont’d)
Some topics (such as lead
paint, asbestos, and PCBcontaining materials) have
extensive insights about
where to find the material
and what steps to take.
The bulk of specifics are on those
pages.
• Steps 2 and 3 provide some follow-up insights
Step 3 is about disposal…
Let’s dig a little deeper
Transport and Disposal
• Transport and disposal of hazardous waste is
regulated by EPA and DTSC
• Transporter must hold a valid registration
issued by DTSC
– A current list of registered hazardous waste
transporters is available in the Registered
Hazardous Waste Transporter Database at:
http://www.dtsc.ca.gov/database/Transporters/Tr
ans000.cfm
38
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 regulations
• Permitted hazardous waste facilities are
contained in DTSC’s Envirostor database at:
http://www.envirostor.dtsc.ca.gov/public/com
mercial_offsite.asp
39
Transport and Disposal
• Wastes generated during the project may
include:
– The originally identified hazardous material
– Solid waste generated as part of clean up process
– Liquid waste generated as part of clean up process

So, let’s recap!
Prior to Demolition,
Step 1 is identification…
• Check All Buildings
– Chemically treated wood
– Asbestos-containing material
– Mercury-containing fixtures and equipment
• Particularly institutional and industrial structures
– Light ballasts
– Exit signs
– Smoke detectors
• Additional Issues for Buildings Built
Prior to 1980
– Lead paint
– PCBs in electrical equipment
– PCBs in caulk, sealants, and other materials
Then…
• Step 2: protect yourself, staff, and building
occupants
• Step 3: comply with state and federal
transportation and disposal laws
