ASP study guide and 12-week plan (ASP11)
What to study for each of the nine BCSP® ASP11 domains, which references BCSP points to, and a 12-week schedule sized to the domain weights.
By the PassCited editorial team. Last reviewed . Facts checked against the sources listed below; how we check.
Short answer
Study the ASP by the nine ASP11 domain weights from BCSP's blueprint. Safety Programs and Concepts is 25%, Fire Prevention and Protection and Industrial Hygiene are 12% each, and Legal is the smallest at 5%. A workable schedule is 10 weeks of content sized to those weights, math practice every week, 1 week of timed practice plus a review week before a 5-hour exam.

Each domain also has a page with free practice questions on the ASP practice questions hub.
Which references to use
BCSP says every ASP question is supported by a published reference, and its ASP reference list is mostly safety textbooks and handbooks. BCSP also says the list is not complete and is not a guaranteed way to pass. You don't need every book. Use the list to fill gaps in the domains where your practice scores are lowest, and go to the regulation itself (eCFR) when a question turns on an OSHA rule.
A 12-week schedule
Ten content weeks sized roughly to the domain weights, then one week of timed practice and a light review week. The weeks are this plan's arithmetic, not a BCSP recommendation; the study plan calculator does the split for your own dates.
| Week | Focus | Weight covered |
|---|---|---|
| 1 | Domain 1, Mathematical Calculations, on a TI-30XS-style calculator | 10% |
| 2 | Domain 2: management systems, hierarchy of controls, risk analysis | |
| 3 | Domain 2: safety fundamentals, hazardous energy, electrical | |
| 4 | Domain 2: incident investigation, management of change, indicators; plus Domain 9, Legal | 25% + 5% |
| 5 | Domain 4, Fire Prevention and Protection | 12% |
| 6 | Domain 6, Industrial Hygiene and Occupational Health | 12% |
| 7 | Domain 8, Training, Education, and Communication | 11% |
| 8 | Domain 5, Emergency Preparedness and Response | 10% |
| 9 | Domain 3, Ergonomics, and Domain 7, Environmental Management | 8% + 7% |
| 10 | Your two weakest domains from practice scores; a second pass on math | |
| 11 | One full 5-hour timed session, then review every miss | |
| 12 | Light review, ID check, test center logistics |
Keep 20 to 30 minutes of math in every week after week 1. Calculation tasks show up outside Domain 1 too, such as the NIOSH lifting equation in Ergonomics.
Habits that make the plan work
- Start each week with 15 to 20 questions on that domain, then read for what you missed.
- Write down why the best answer beats the runner-up, not just the right letter.
- Practice with the formula given to you. BCSP doesn't allow a formula sheet; formulas are given in the question unless the question tests the formula itself.
- Answer the free question of the day on rest days.
FAQ
What is the best ASP study guide?
There is no official BCSP study guide book. BCSP publishes the ASP11 blueprint and a reference list for free, and sells a Self-Assessment. Paid courses and books are compared alphabetically, with prices from each seller's page, in the ASP exam prep comparison.
How many hours should I study for the ASP?
BCSP does not publish a number. This plan works out to roughly 100 to 120 hours at 8 to 10 hours a week; adjust it to your practice scores by domain.
Which ASP domain is the biggest?
Domain 2, Safety Programs and Concepts, at 25% of ASP11.
How long is the ASP exam?
BCSP allows 5 hours. Do at least one full-length timed session before test day.
Is my old ASP10 book still useful?
Partly. BCSP says most concepts carried over to ASP11 but the weights shifted and some topics moved, so check your book's topic list against the ASP11 blueprint.

Domain 1: Mathematical Calculations
Question 1
A maintenance mechanic's 8-hour shift includes 4 hours at 97 dBA, 2 hours at 88 dBA, 2 hours at 92 dBA. Use D = 100 × (C1/T1 + C2/T2 + …), where C is the hours at each level and T is the reference duration for level L from OSHA Table G-16a (for example 8 h at 90 dBA, 7.0 h at 91, 6.1 h at 92, 4 h at 95, 2 h at 100). Using OSHA's noise dose method (Table G-16a reference durations), what is the mechanic's daily noise dose?
Show answer and source: 29 CFR 1910.95, Appendix A
Answer: B. 185.0%
OSHA's noise rule, 29 CFR 1910.95 Appendix A, sums time at each level divided by that level's Table G-16a reference duration: D = 100 × (4/3.0 + 2/10.6 + 2/6.1) = 100 × 1.850 = 185.0%. 92.5% is half the correct dose. 139.1% and 307.4% use reference durations that do not match Table G-16a.
On the job
A safety coordinator at a stamping plant has dosimeter notes for a press operator: 3 hours near the blanking presses at 95 dBA and 5 hours at 85 dBA in the packing area. The coordinator divides each period's time by its Table G-16a reference duration and adds the fractions. Because the sum is based on partial doses, one quiet period does not average away the loud one, and the result is the press operator's total noise dose over the work day.

Answer B comes from
29 CFR 1910.95, Appendix A(opens ecfr.gov in a new tab)“When the workshift noise exposure is composed of two or more periods of noise at different levels, the total noise dose over the work day is given by: D = 100(C1 / T1 + C2 / T2 + Cn / Tn), where Cn indicates the total time of exposure at a specific noise level, and Tn indicates the reference duration for that level as given by Table G-16a.”
Domain 2: Safety Programs and Concepts
Question 2
A tower climber falls and hangs motionless in a harness. Before rescue, a safety trainer explains that blood is collecting in the veins of the climber's legs. According to OSHA's bulletin, what is this condition called, and what can it cause?
Show answer and source: OSHA SHIB 03-24-2004 (updated 2011), Suspension Trauma/Orthostatic Intolerance, PDF p. 1
Answer: C. Venous pooling, which can cause orthostatic intolerance
OSHA's bulletin says that in a sedentary position blood can accumulate in the veins, called venous pooling, and cause orthostatic intolerance. The harmless-numbness choice contradicts that link. Reversing the terms is wrong because orthostatic intolerance is the result, not the cause. Palpitations are only a possible symptom, and the bulletin does not define a condition caused by loose fit.
On the job
A safety coordinator at a water tank painting job trains crews on harness use before they climb. She explains that a worker hanging still after a fall can have blood accumulate in the leg veins, which is called venous pooling, and that it can cause orthostatic intolerance. That is why the rescue plan sets a fast retrieval method instead of leaving a worker suspended.

Answer C comes from
OSHA SHIB 03-24-2004 (updated 2011), Suspension Trauma/Orthostatic Intolerance, PDF p. 1(opens govinfo.gov in a new tab)“While in a sedentary position, blood can accumulate in the veins, which is commonly called “venous pooling,” and cause orthostatic intolerance [3].”
Domain 3: Ergonomics
Question 3
A receiving clerk opens tightly sealed produce crates by pounding the lids with the heel of his hand. He also rests his forearm on the sharp metal edge of the packing table while he works. A safety coordinator wants to label the main risk factor in these actions. Which risk factor fits best?
Show answer and source: OSHA 3192, Guidelines for Retail Grocery Stores: Ergonomics for the Prevention of Musculoskeletal Disorders (2004), PDF p. 9
Answer: B. Contact stress, from pressing the body against hard or sharp edges or using the hand as a hammer
OSHA's retail grocery ergonomics guidelines define contact stress as pressing the body against hard or sharp edges, or using the hand as a hammer. That matches the pounding and the forearm on the edge. Repetition, force, and static posture are separate risk factors, and the stem describes none of them as the main problem.
On the job
An EHS manager at a commercial laundry observes a worker who clears jammed linen carts by hitting the cart frame with the palm of her hand. A hard metal rail also presses into her ribs each time she leans over the folding table. The manager recognizes contact stress, which is pressing the body against hard or sharp edges or using the hand as a hammer, and has the rail padded and a rubber mallet issued.

Domain 4: Fire Prevention and Protection
Question 4
A chemical manufacturer is preparing its hazard evaluation for a new fine organic powder. The draft covers skin irritation, inhalation toxicity, and flammability of the bulk solid. It does not address whether the powder can form an explosive dust cloud. The product is shipped to customers in bags. What does OSHA's guidance say about this draft?
Show answer and source: OSHA 3371-08, Hazard Communication Guidance for Combustible Dusts (2009), PDF p. 4
Answer: D. It is incomplete, because the evaluation must consider all discernible hazards, including explosibility
OSHA's combustible dust hazard communication guidance says a hazard evaluation of dusts must consider all discernible hazards, including explosibility. The draft omits that, so it is incomplete. Limiting it to health and bulk flammability is wrong, as is shifting it to customers. A past incident at the plant is not a condition for the duty.
On the job
An EHS manager at a plant that blends fine plastic additives reviews the hazard evaluation for a new powder before the safety data sheet is finalized. The draft covers toxicity and skin contact, but nothing about whether suspended dust could explode. Guidance says the evaluation must consider all discernible hazards, including explosibility, so the manager sends the draft back until explosibility testing is added.
Study aid, not site-specific safety advice. The official rule controls.
Answer D comes from
OSHA 3371-08, Hazard Communication Guidance for Combustible Dusts (2009), PDF p. 4(opens osha.gov in a new tab)“hazard evaluation must be conducted taking into consideration all discernible hazards, including that of explosibility.”
