MD Asbestos Abatement study plan

Classify the six regulated asbestos minerals into serpentine and amphibole groups, and state one distinguishing property (fiber curvature, acid resistance, tensile strength) for each.

Explain the dose pathway from disturbance to disease, naming the fiber criteria that make a particle hazardous: length greater than 5 micrometers, aspect ratio of at least 3 to 1, and respirable width.

Differentiate asbestosis, lung cancer, mesothelioma, and pleural plaques by target tissue, typical latency, and the multiplicative effect of cigarette smoking.

Define OSHA work Classes I through IV under 29 CFR 1926.1101 and assign a realistic Maryland job-site example to each class.

Sketch a three-stage decontamination unit and label clean room, shower, equipment room, worker travel direction, and airflow direction.

Design a negative-pressure containment for a 500 square foot pipe-riser removal, specifying 6-mil fire-retardant poly, critical barriers, sealed penetrations, and a target differential of minus 0.02 inches water column.

Sequence containment construction and teardown in at least 12 ordered steps, from utility lockout and critical barriers through final visual inspection and HEPA vacuuming of poly before disposal.

Select among wet removal, glove bag, mini-enclosure, and HEPA vacuum for five written scenarios, and justify each choice using friability, location, and size of the component.

List prohibited practices (dry sweeping, compressed air, dry cutting, dropping unbagged debris) and name the engineering or work-practice control that replaces each one.

Calculate air scrubber quantity for a 10,000 cubic foot containment needing 4 air changes per hour using 500-cfm HEPA units, and show the unit conversion.

State the NESHAP thresholds (160 square feet of facility component, 260 linear feet of pipe) and the 10-working-day notification rule, then apply both to three renovation scenarios.

Compare the OSHA permissible exposure limit of 0.1 fibers per cubic centimeter as an 8-hour TWA, the 1.0 f/cc 30-minute excursion limit, and AHERA school clearance of 0.01 f/cc by PCM or 70 structures per square millimeter by TEM.

Map Maryland requirements, including MDE accreditation and licensing, project notification, permit, and waste shipment tracking, to their COMAR citations and to the parallel federal rule.

Outline employer duties under 1926.1101: initial and periodic exposure monitoring, regulated area posting, competent person authority, hygiene facilities, and recordkeeping.

Separate AHERA scope (K-12 schools, management plans, 3-year reinspection, 6-month periodic surveillance) from NESHAP coverage of demolition and renovation.

Walk a complete Class I pipe-removal project from notification through clearance, naming the regulator, form, and inspector sign-off at each checkpoint.

Resolve five enforcement-style scenarios (missing notification, visible emissions, dry removal, failed negative pressure, unlabeled waste) by citing the violated provision and the corrective action.

Reconcile the week 2 containment design with Maryland submittal, inspection, and clearance requirements, and revise any step that would not pass state review.

Explain how a competent person decides to stop work, using at least three trigger conditions tied to containment integrity, exposure monitoring, or visible debris.

Build a respirator selection table that pairs assigned protection factors with exposure ranges, from half-mask P100 through full-face and powered air-purifying to supplied-air, per 1926.1101(h).

Distinguish qualitative (saccharin, Bitrex) from quantitative (portacount, generated aerosol) fit testing, and state when each is acceptable and how often retesting is required.

Order the steps a worker must complete before donning a respirator: medical evaluation, annual fit test, user seal check, and pre-use inspection of valves and filters.

Write a filter and cartridge change schedule keyed to exposure level, visible loading, and breathing resistance, and explain why P-series filters are required for asbestos.

Describe correct donning and doffing order at the decon line so that respirators are removed only in the clean room after showering.

Sequence the full decontamination routine from work area to clean room, including HEPA vacuuming, wet wiping, bagging of reusable PPE, and showering before street clothes.

List hygiene prohibitions inside the regulated area (eating, drinking, smoking, chewing, applying cosmetics) and explain the contamination pathway each one creates.

Describe PCM sampling by NIOSH 7400: 25-mm MCE cassette, 0.8-micrometer pore size, pump calibration, flow rate range, and counting rules at 400x.

Explain aggressive sampling, the five-minute disturbance period, sample placement, and the clearance criterion applied before containment is dismantled.

Draft a chain-of-custody and field data sheet that captures pump ID, calibration pre- and post-sample, times, flow, volume, and laboratory request.

Specify packaging for friable and non-friable waste: 6-mil double bagging or sealed drums, sharp-object protection, wetting, and gooseneck closure, and explain why visible dust on the exterior fails inspection.

Label waste per the NESHAP warning format and DOT UN 2212 Class 9 requirements, and identify the shipping paper and waste shipment record fields a generator must complete.

Trace a load from generator to permitted landfill, listing the records that must be retained and the reason non-permitted disposal is a violation.

Outline the medical surveillance trigger (30 or more days per year in Class I, II, or III work or exposure at or above the PEL), and list exam components including history, chest X-ray, and pulmonary function.

State retention rules for exposure records (30 years), medical records (duration of employment plus 30 years), and training documentation, and describe how a worker requests access.

Re-test every missed item from weeks 1 through 7 and write a corrected one-sentence rule for each, eliminating repeat errors.

Complete a 50-question timed mock exam spanning all eight domains and review each rationale against primary-source citations.

Rehearse the five highest-risk calculations: ACH and scrubber sizing, TWA from multiple samples, sampling volume, clearance comparison, and NESHAP threshold determinations.

Consolidate all weekly deliverables into a single indexed study binder with tabbed sections by domain for final review.
