Safety Trained Supervisor Hazard Identification and Awareness 2 — Questions and Answers
Question 1: What is the primary difference between a hazard and a risk?
- Hazards are physical; risks are financial
- A hazard is a source of potential harm; risk is the likelihood and severity of harm from it (Correct answer)
- Hazards only in construction; risks everywhere
- No practical difference
Correct answer: A hazard is a source of potential harm; risk is the likelihood and severity of harm from it
A hazard has potential to cause harm; risk combines likelihood and severity of that harm occurring.
The same hazard can present different risk levels depending on exposure and controls. A high-voltage panel is low risk when enclosed and locked, high risk when exposed to untrained workers.
Question 2: Which inspection technique follows a product or process from beginning to end?
- Random walk-through
- Process flow analysis (Correct answer)
- Continuous monitoring
- Statistical sampling
Correct answer: Process flow analysis
Process flow analysis traces a process from start to finish identifying hazards at each stage.
It reveals hazards during transitions between steps, at interfaces between areas, during startup and shutdown, and during non-routine operations like maintenance.
Question 3: What is the purpose of a Safety Data Sheet in hazard identification?
- Purchase pricing
- Comprehensive information about chemical hazards, safe handling, storage, and emergency measures (Correct answer)
- Marketing document
- Replacement for hazard assessments
Correct answer: Comprehensive information about chemical hazards, safe handling, storage, and emergency measures
SDSs provide detailed chemical hazard information, handling procedures, and emergency measures.
SDSs follow a standardized 16-section GHS format covering identification, hazards, composition, first aid, firefighting, accidental release, handling, exposure controls, properties, stability, and more.
Question 4: How do leading indicators help in proactive hazard identification?
- Only useful after an incident
- They measure activities predicting future incidents, enabling early intervention (Correct answer)
- Track lost-time injuries
- Measure compensation costs
Correct answer: They measure activities predicting future incidents, enabling early intervention
Leading indicators measure proactive activities that predict and precede incidents.
Includes hazard reports, near-miss rates, observation frequency, overdue corrective actions, and training completion. Declining leading indicators signal weakening safety systems.
Question 5: What is change analysis in hazard identification?
- Tracking regulatory changes
- Comparing current conditions to a baseline to identify what changed and may have introduced new hazards (Correct answer)
- Documenting personnel changes
- Financial analysis of changes
Correct answer: Comparing current conditions to a baseline to identify what changed and may have introduced new hazards
Change analysis compares current conditions to a baseline to find changes that introduced hazards.
Changes include new equipment, modified processes, personnel changes, environmental shifts, and gradual degradation. Used proactively for planned changes and reactively during incident investigations.
Question 6: What are key elements of an effective hazard reporting system?
- A suggestion box checked monthly
- Simple reporting, non-punitive culture, timely response, feedback to reporters, tracking to resolution (Correct answer)
- Anonymous email to legal
- Complex form requiring multiple signatures
Correct answer: Simple reporting, non-punitive culture, timely response, feedback to reporters, tracking to resolution
Effective systems are simple, non-punitive, responsive, provide feedback, and track to resolution.
Without these elements workers stop reporting. Key elements include accessible mechanisms, non-punitive culture, timely response, feedback loops, tracking, trend analysis, and visible management support.
