Guide for asbestos abatement contractors · checked 11 November 2026
Asbestos abatement software for notices, crews, air and waste
An asbestos job is fixed in place by paper before a crew arrives. The NESHAP notice goes in 10 working days ahead and the job cannot start on any other date. Every worker needs a current accreditation, every bag needs the OSHA label and the generator's name, and the signed waste shipment record has to come back from the landfill within 35 days. This guide covers how the work runs, the federal, state and city rules, and what to look for in software.

A 30-minute call. We show you asbestos abatement contractors workflows running in Fieldproxy, built around how you work.
Short answer
Asbestos abatement contractors mostly run on a mix: FieldFlo or Procore for projects, time and daily reports, an air monitoring firm's reports as PDFs, and spreadsheets for notices, accreditations and waste shipment records. Building owners and schools often keep their side in Ecesis or similar. The deciding features are NESHAP and state notice dates that block an early start, per-worker accreditation and medical records, daily regulated-area logs, clearance results, and the 35 and 45 day waste record clock. Fieldproxy is one option. Best for processes that don't fit a template, set up for you: it is built around your notices, crews, monitors and landfills.

How a job runs
One asbestos abatement job, from first call to paid
The order the work really happens in, and what has to be written down at each step so nothing is argued about later.
- 1
Start from the survey
NESHAP requires the owner or operator to thoroughly inspect the facility for asbestos before a renovation or demolition, including Category I and II nonfriable material. The abatement contractor usually gets that inspector's report or a project designer's specification with the materials, locations and quantities. In New York City an ACP-5 investigator form is filed when asbestos is absent, will not be disturbed, or the work is a minor project.
- 2
Classify the work and price it
OSHA sorts the work into classes. Class I removes thermal system insulation and surfacing material, Class II removes other ACM such as floor tile, wallboard, roofing and mastic, Class III is repair and maintenance that disturbs ACM, and Class IV is custodial work and cleanup. The class decides the controls, the training and the crew size, so it belongs on every estimate line along with the square or linear footage.
- 3
File the notices
Federal NESHAP notice goes to the state or local agency at least 10 working days before stripping or removal starts, naming the amount of regulated material, start and completion dates, work practices, the waste transporter and the disposal site. Texas DSHS wants the same 10 working days and charges $30 per asbestos reporting unit. NYC DEP wants an ACP-7 at least a week ahead, and California registered contractors notify the nearest Cal/OSHA district office 24 hours before each job.
- 4
Staff the job with the right people
NESHAP requires at least one trained supervisor on site whenever regulated material is disturbed, with refresher training every 2 years and the training evidence posted at the site. OSHA requires a competent person, and for Class I and II work with barriers, training equal to the EPA Model Accreditation Plan: a 4-day worker course and a 5-day contractor/supervisor course, each with at least 14 hours of hands-on training and an annual refresher.
- 5
Set up the regulated area
For Class I work over 25 linear or 10 square feet of TSI or surfacing material, OSHA requires critical barriers and a decontamination area with an equipment room, shower and clean room in series. A negative pressure enclosure holds at least 4 air changes per hour and at least -0.02 column inches of water. Signs read DANGER, ASBESTOS, MAY CAUSE CANCER, CAUSES DAMAGE TO LUNGS, AUTHORIZED PERSONNEL ONLY.
- 6
Remove wet and monitor every shift
NESHAP requires the material to be adequately wet during stripping and kept wet until it is collected and contained. On Class I jobs the competent person inspects at least once every work shift. Personal air samples show whether the crew stayed under 0.1 f/cc, and the initial exposure assessment is made immediately before or at the start of the operation unless a negative exposure assessment is on file.
- 7
Bag, label and ship the waste
Waste is sealed wet in leak-tight containers carrying the OSHA label (DANGER, CONTAINS ASBESTOS FIBERS, MAY CAUSE CANCER, CAUSES DAMAGE TO LUNGS, DO NOT BREATHE DUST, AVOID CREATING DUST) plus the generator's name and the location where the waste was generated. Vehicles are marked while loading. A waste shipment record goes with the load and the landfill signs it on delivery.
- 8
Pass clearance
On AHERA school projects, clearance follows a visual inspection and aggressive air sampling. Larger projects are cleared by transmission electron microscopy: five samples inside, five outside and blanks, 13 in all per EPA, with an inside average at or below 70 structures per square millimeter. Projects up to 160 square feet or 260 linear feet can clear by PCM at 0.01 f/cc or less on each of five samples. Outside schools, the specification or the state sets the test.
- 9
Close out and keep the records
The signed waste shipment record should be back within 35 days; at 45 days the generator reports in writing to the agency. In New York City the project monitor files the ACP-15 within 21 days of completion. Waste records are kept at least 2 years, OSHA exposure monitoring records 30 years, medical records the length of employment plus 30 years, and training records one year past employment.
What to record
The fields every asbestos abatement job should capture

Numbers
The thresholds, deadlines and retention periods that run an asbestos job
Footage and dates decide the paperwork in this trade more than price does: they decide whether NESHAP applies, which notice is due when, how the area is built, how it is cleared, and how long every record is kept.

Where it breaks
Where spreadsheets and generic software fall over
The general contractor asks the crew to start Thursday instead of the following Monday. The NESHAP notice says Monday, and an earlier start needs a fresh notice 10 working days ahead.
The notice number and dates sit on the job; moving the start earlier blocks dispatch until a new notice date at least 10 working days out is recorded, or the job is flagged an emergency with the reason.
A worker's annual refresher lapsed three weeks ago. Nobody noticed until the state inspector asked for the crew's certificates at the door of the containment.
Each worker holds discipline, course date, refresher due date, medical date and fit test; someone with anything expired cannot be put on a regulated-area shift.
Five roll-offs went to the landfill in March. In May the agency asks for the signed waste shipment records and two are missing, with no exception report filed.
Each shipment starts a 35-day clock to chase the landfill and a 45-day clock for the written report, and the job cannot close until every signed copy is attached.
The survey said 1,200 sq ft of floor tile and mastic. The crew finds pipe lagging behind a chase wall, the total jumps, and the notice still shows the old amount.
Removed quantities are logged per area against the notified amount; when the running total moves 20% or more, the job asks for the notice update and a change order before work continues on the new material.
The manometer printout for night shift is a photo on a supervisor's phone, and the air sample results arrive as a PDF a week later, attached to nothing.
Each shift log holds the pressure reading, competent person inspection and sample IDs; lab results are matched to sample IDs and anything over 0.1 f/cc is flagged on the shift.
A NYC job finished clearance on the 2nd. The project monitor's ACP-15 was never filed and the building's DOB sign-off stalls.
Completion starts the 21-day ACP-15 clock with a named owner, and the close-out pack lists ACP-7, ACP-8s, clearance, ACP-15 and waste records with what is still missing.

Software options
What software asbestos abatement contractors actually use
Judge each one on whether it fits the way your jobs run, not on the feature list. Bring a real job to every demo.
FieldFlo
US abatement and environmental subcontractors running several field crews
Built for specialty subcontractors: daily field reports, time tracking with payroll and job costing, waste and scrap tracking, equipment, change orders and training certificates. Ask how it holds NESHAP notice dates, air sample results and the waste shipment record clock.
Procore
Abatement contractors working inside large general contractor projects
Construction project management with daily logs, documents and RFIs, often already used by the GC. Asbestos-specific records such as accreditations, notices and waste shipment records would be custom forms.
Ecesis
Building owners, facility managers and school districts tracking asbestos across a portfolio
EHS software from EnviroData Solutions with abatement project tracking, notification management and AHERA records. Mostly an owner-side tool; contractors meet it when the owner runs the program.
TEAMS
UK asbestos consultancies and analysts
Asbestos management platform for surveys and air monitoring, with HSG248 air tests and four-stage clearance certificates. Aimed at analysts rather than removal contractors.
Jobber
Small residential abatement companies doing popcorn ceilings, floor tile and pipe wrap
Good for quotes, scheduling and invoices. Notices, accreditations, shift logs, air results and waste shipment records would be custom fields or attachments.

Questions to ask any vendor
- Can a job hold the NESHAP or state notice number and dates, and block dispatch when the start moves earlier than 10 working days out?
- Does it track each worker's accreditation discipline, refresher, medical surveillance and fit test, and keep expired people off regulated-area shifts?
- Can the supervisor log barriers, manometer readings, competent person inspections and air sample IDs per shift, offline in a basement plant room?
- Does it match lab air results to sample IDs and flag anything over 0.1 f/cc?
- Can it run each waste shipment record through the 35 and 45 day clocks and stop the job closing until the signed copy is attached?
- Can it keep exposure and medical records for 30 years and produce them by worker on request?

Asbestos abatement on Fieldproxy: built around how you already work
A Fieldproxy setup for an asbestos abatement contractor is built around the job as the three regulators see it: the notice and its fixed dates, the crew and their accreditations inside the regulated area, the air results each shift, and the waste until the landfill signs for it. Federal, state and city rules are built into the statuses and blocks, so a crew cannot start ahead of its notice and a job cannot close with a waste record missing.
Module 1
Projects, areas and materials
Material type, category, footage and class decide every rule that follows.
- Records: Customer (owner, GC, school district) > Facility > Project > Area > Material line
- Material line fields: type (TSI, surfacing, floor tile, mastic, roofing, wallboard), friable or Category I or II nonfriable, quantity in sq ft, linear ft or cubic ft, OSHA class
- Auto-flag: NESHAP threshold crossed (260 lf, 160 sq ft, 35 cu ft), NYC asbestos project (over 25 lf or 10 sq ft), California 100 sq ft, Texas ARUs
- Status: Survey received, Estimating, Awarded, Notice filed, Mobilizing, In regulated area, Awaiting clearance, Cleared, Waste records open, Closed
Module 2
Estimates and change orders
The price is built from the survey quantities and the class, and found material changes both.
- Estimate lines from material lines: quantity, class, crew days, decon units, negative air machines, disposal cubic yards, air monitoring
- Change order when removed quantity passes the notified amount by e.g. 10%, with photos and the survey reference
- Estimate and change order PDFs from your own template
Module 3
Notices and permits
The notice date is the start date, and each agency has its own form and clock.
- Per project: NESHAP agency, notice number, start and completion dates, amendments; emergency flag and reason
- City and state extras: NYC ACP-7, ACP-8s and ACP-15; Texas ARUs and fee; NY SH 483; California 24-hour notice
- Blocks: no shift scheduled before the notified start; an earlier start needs a new notice 10 working days out; a 20% quantity change asks for the update
Module 4
Crew, accreditations and medical
Every person in the regulated area has to be current on the day, and the records outlive the job by decades.
- Per worker: MAP discipline (worker, supervisor), course and refresher dates, state license, NESHAP-trained flag, medical surveillance date, respirator model and fit test
- Block: anyone expired cannot be put on a regulated-area shift; every shift needs a NESHAP-trained supervisor and a competent person
- Days per year on Class I to III work counted toward the 30-day medical trigger; expiry alerts e.g. 30 days ahead
Module 5
Regulated area shift log
The shift log is the defense when an inspector, the owner's consultant or a former worker asks what happened.
- Per shift: barriers and decon checked, negative air machine IDs, manometer reading against -0.02 column inches of water, air changes
- Competent person inspection time and findings (required every shift on Class I), wetting method, quantity removed per area, bags produced
- Photos time-stamped and GPS-tagged; works offline in plant rooms and crawl spaces
Module 6
Air monitoring results
Results come from an outside lab days later and have to land on the right worker and shift.
- Sample record: ID, type (personal, area, clearance), worker or location, pump, flow, volume, method (PCM or TEM), lab, result
- Personal results above 0.1 f/cc TWA or 1.0 f/cc excursion flagged on the shift and the worker
- Exposure records kept 30 years and printable per worker
Module 7
Waste shipments
The generator stays responsible until the landfill signs, and the clock is federal.
- Per load: waste shipment record number, cubic yards, transporter, disposal site, date shipped, signed copy returned date
- Day 35 chase and day 45 written exception report, each with a named owner
- Block: project cannot close until every load has a signed copy attached; records kept at least 2 years
Module 8
Equipment
Decon units, negative air machines and manometers move between jobs and need their own checks.
- Asset per unit: type, serial, HEPA filter change date, last check date
- On job and area, days on site for billing, decontaminated and returned
Module 9
Clearance, close-out and the owner portal
Owners, GCs and schools want one pack that shows the job was done and cleared.
- Visual inspection, clearance method (PCM or TEM) and result; a failed clearance reopens the area
- Close-out pack PDF: notices and amendments, crew accreditation list, shift logs, air results, clearance, waste shipment records
- Portal per owner or GC with the pack and invoices; QuickBooks or Xero sync

Most use a mix: FieldFlo or Procore for projects, daily reports and time, lab PDFs for air results, and spreadsheets for notices, accreditations and waste shipment records. Owners and schools often run Ecesis or similar on their side. What matters is tying notice dates, crew accreditations, shift logs, air results and the waste record clock to each job. Fieldproxy is set up around your own notices, crews and landfills.
How far in advance do you have to notify for asbestos removal?
Under the federal NESHAP, at least 10 working days before stripping or removal starts, and the job may not start on any other date than the one in the written notice. Emergency renovations are notified no later than the following working day. States and cities add their own: Texas DSHS 10 working days, NYC DEP's ACP-7 at least a week ahead, California 24 hours before each job for registered contractors.
How much asbestos triggers NESHAP?
260 linear feet on pipes, 160 square feet on other facility components, or 35 cubic feet off facility components where it could not be measured first. Below that the full notice and work practice rules do not apply, though OSHA and state rules still can. Residential buildings with four or fewer dwelling units are outside NESHAP.
What is the difference between Class I, II, III and IV asbestos work?
Under OSHA 1926.1101, Class I removes thermal system insulation and surfacing material, Class II removes other ACM such as floor tile, wallboard, roofing and mastic, Class III is repair and maintenance that disturbs ACM, and Class IV is custodial work that contacts but does not disturb it, plus cleanup of debris.
What is the OSHA exposure limit for asbestos?
0.1 fiber per cubic centimeter as an 8-hour time-weighted average, and an excursion limit of 1.0 f/cc averaged over 30 minutes. OSHA's own page adds that there is no safe level of exposure.
How long is asbestos training?
Under the EPA Model Accreditation Plan, at least 4 days for workers and 5 days for contractor/supervisors, each with at least 14 hours of hands-on training and an exam, then an annual refresher. Inspectors take 3 days. OSHA Class III training is at least 16 hours and Class IV at least 2 hours.
What is an asbestos waste shipment record?
The NESHAP form that travels with each load of asbestos waste, naming the generator, quantity, transporter and disposal site. The landfill signs it on delivery. If the generator does not get the signed copy within 35 days it must contact the transporter or landfill, and at 45 days it reports in writing to the agency. Copies are kept at least 2 years.
What does asbestos clearance testing check?
In schools under AHERA, a visual inspection then aggressive air sampling. Larger projects clear by TEM with an inside average at or below 70 structures per square millimeter, using 13 samples. Projects up to 160 square feet or 260 linear feet can clear by PCM with each of five samples at 0.01 f/cc or less. Other buildings follow the specification or state rule.
How long must asbestos records be kept?
OSHA exposure monitoring records 30 years, medical records the length of employment plus 30 years, and training records one year past employment. NESHAP waste shipment records at least 2 years.
Do you need a license to remove asbestos?
OSHA ties Class I and II training to the EPA Model Accreditation Plan, and states such as Texas, New York and California license or register contractors and workers on top. California needs a Cal/OSHA registration for 100 square feet or more, renewed yearly, plus a CSLB C-22 license or the ASB certification for roofing. In Great Britain, licensable work needs an HSE licence and ASB5 notice 14 days ahead.
