SafePath CSP Exam Prep Guide & Seven-Domain Curriculum

Domain 1: Advanced Application of Safety Principles (25%)

Prevention through design, process safety, workplace hazards, life safety, materials handling and equipment.

Study action: Explain why an elimination or engineering control addresses the source; practice a field scenario before reviewing your answer.

Domain 2: Program Management (25%)

Management systems, culture, incident investigation, change management, audits, indicators, leadership and data.

Study action: Build a corrective-action chain from evidence to owner, deadline and effectiveness check; distinguish leading from lagging indicators.

Domain 3: Risk Management (15%)

Risk identification, analysis, evaluation, treatment, monitoring and financial risk strategies.

Study action: Rank two credible hazards using severity and likelihood, then separate physical prevention from insurance or financial transfer.

Domain 4: Emergency Management (9%)

Emergency planning, incident command, continuity, fire prevention and protection, hazmat movement and workplace violence.

Study action: Walk through a release or fire: initial protection, notification, command, response, recovery and an exercise.

Domain 5: Environmental Management (6%)

Pollution prevention, hazardous materials and waste, sustainability and environmental impacts.

Study action: Trace a material from receipt through storage, use, spill prevention and lawful waste handling.

Domain 6: Occupational Health and Applied Science (10%)

Exposure assessment, industrial hygiene, public health, toxicology, ergonomics, chemistry and physics.

Study action: Check units and assumptions in every calculation; select sampling and controls appropriate to the exposure route.

Domain 7: Training (10%)

Training needs, design, delivery, adult learning, coaching and effectiveness evaluation.

Study action: Set an observable performance objective and test it through a demonstration and later workplace observation.

Question 1 · D1 · Applied safety

Workers repeatedly climb onto a conveyor to clear jams. Which is the strongest feasible long-term control?

Best answer: C. Redesign the feed to prevent jams and provide guarded clearing access

1. A. Repeat annual training
2. B. Post a warning sign
3. C. Redesign the feed to prevent jams and provide guarded clearing access
4. D. Require a second worker to watch

Why: The redesign removes or reduces the cause and provides engineered access. Training, signs and a spotter depend on continued human attention; they may supplement, but do not replace, a feasible design control. For the immediate jam, isolate hazardous energy under the applicable procedure before intervention.

Question 2 · D2 · Program management

A site reports fewer recordable injuries this quarter but repeated overdue corrective actions. What is the best management response?

Best answer: C. Review action quality, owners and deadlines, then verify controls in the field

1. A. Declare the program effective from the lower injury count
2. B. Close overdue actions administratively
3. C. Review action quality, owners and deadlines, then verify controls in the field
4. D. Stop tracking injury counts

Why: A lower lagging count alone cannot establish that risk is controlled. Overdue actions are a leading signal requiring ownership, completion and effectiveness verification. Keep both measures; do not assume a short injury-free period proves prevention.

Question 3 · D3 · Risk management

A contractor purchases insurance for a hazardous lifting operation. What has the insurance primarily changed?

Best answer: B. The financial allocation of some losses

1. A. The load's physical hazard
2. B. The financial allocation of some losses
3. C. The sling's rated capacity
4. D. The lift's probability of failure

Why: Insurance can transfer or share financial consequences under policy terms; it does not remove the load, reduce sling tension or substitute for a lift plan and physical controls. Review exclusions and retained risk separately.

Question 4 · D6 · Occupational health

A steady contaminant source emits 120 mg/min into a well-mixed space. Supply concentration is 2 mg/m³ and the illustrative target is 10 mg/m³. What theoretical dilution flow is required?

Best answer: B. 15 m³/min

1. A. 12 m³/min
2. B. 15 m³/min
3. C. 60 m³/min
4. D. 120 m³/min

Why: Q = G/(Ctarget − Cin) = 120 mg/min ÷ (10 − 2) mg/m³ = 15 m³/min. This ideal steady-state estimate assumes complete mixing. Real control design must consider local capture, mixing, transient peaks and the applicable exposure criterion.

Question 5 · D7 · Training

An operator passes a lockout quiz after training. Which additional evidence best tests whether the training works?

Best answer: C. A supervised lockout demonstration followed by observation on the job

1. A. Course attendance alone
2. B. A more colorful slide deck
3. C. A supervised lockout demonstration followed by observation on the job
4. D. Another copy of the same quiz

Why: A demonstration shows task performance, while later observation checks transfer to the work setting. Attendance and recall can support records, but neither proves correct execution of a critical procedure.

1. Total recordable incident rate (TRIR)

TRIR = (recordable cases × 200,000) / hours worked

Apply: Identify the OSHA-recordable cases and actual hours for the same period. Multiply cases by 200,000, then divide by hours.

Worked example: 3 cases and 400,000 hours → (3 × 200,000) / 400,000 = 1.5 cases per 100 full-time workers.

Check: The 200,000-hour base represents 100 workers at 40 hours for 50 weeks; it is a normalization, not the site's headcount. BLS incidence-rate method.

2. Days-away, restricted or transferred rate (DART)

DART = (qualifying DART cases × 200,000) / hours worked

Apply: Count qualifying cases, not lost days. Use the same period and hours denominator as the incident-rate comparison.

Worked example: 2 DART cases and 400,000 hours → (2 × 200,000) / 400,000 = 1.0.

Check: DART counts cases involving days away, restricted work or job transfer; do not substitute the total recordable count. BLS DART calculation.

3. Fatal accident rate (FAR; IOGP convention)

FAR = (fatalities × 100,000,000) / hours worked

Apply: Confirm the reporting convention first. Count fatalities and hours from the same defined population and period, then apply the 100-million-hour base.

Worked example: 1 fatality in 20,000,000 hours → (1 × 100,000,000) / 20,000,000 = 5 fatalities per 100 million hours.

Check: Organizations use different fatality-rate bases. Label the IOGP convention and never compare unlike denominators without converting them. IOGP definition.

4. Ideal steady-state dilution ventilation

Q = G / (Ctarget − Cin)

Apply: Express generation G in mass/time and both concentrations in the same mass/volume unit. Subtract supply concentration from the target; divide G by that positive difference.

Worked example: G = 120 mg/min, Ctarget = 10 mg/m³, Cin = 2 mg/m³ → Q = 120 / 8 = 15 m³/min.

Check: This simplified mass balance assumes a well-mixed space at steady state. It is not a complete ventilation design or a substitute for source capture and exposure assessment. NIOSH ventilation reference.

5. Two-leg symmetric sling tension

T per leg = W / (2 × sin θ), where θ is measured from horizontal

Apply: Find the supported load W, confirm two equal legs and a centered load, measure each leg's angle from horizontal, then compute tension and check the rated configuration.

Worked example: W = 2,000 lb at θ = 30° → T = 2,000 / (2 × 0.5) = 2,000 lb per leg.

Check: As the angle becomes flatter, tension rises. Account for the actual center of gravity, hardware, dynamic effects and manufacturer's rated sling-angle capacities. OSHA sling-angle tables.
