HSE Workplace Safety Management and Risk Control 3 — Questions and Answers
Question 1: A quantitative risk assessment assigns a numerical probability to hazard events. Which tool is most commonly used for this purpose?
- Fishbone diagram
- Fault Tree Analysis (FTA) (Correct answer)
- SWOT analysis
- Pareto chart
Correct answer: Fault Tree Analysis (FTA)
Fault Tree Analysis uses Boolean logic and probability values to calculate the likelihood of a top-level undesired event.
Question 2: Which of the following is a leading indicator of safety performance?
- Number of recordable injuries per year
- Lost workday case rate
- Percentage of safety observations completed on time (Correct answer)
- Workers' compensation cost
Correct answer: Percentage of safety observations completed on time
Leading indicators measure proactive safety activities (like observations) that predict future performance, unlike lagging indicators that count past incidents.
Question 3: OSHA's General Duty Clause (Section 5(a)(1)) requires employers to:
- Provide safety training only in English
- Maintain a drug-free workplace program
- Furnish a workplace free from recognized serious hazards (Correct answer)
- Submit annual injury statistics to OSHA
Correct answer: Furnish a workplace free from recognized serious hazards
The General Duty Clause requires employers to provide a workplace free from recognized hazards likely to cause death or serious harm.
Question 4: What is the minimum required content of an emergency action plan under OSHA 29 CFR 1910.38?
- Evacuation procedures and employee accounting methods (Correct answer)
- Incident cost analysis and insurance contacts
- Equipment replacement schedules and vendor contacts
- Annual safety budget and training calendar
Correct answer: Evacuation procedures and employee accounting methods
OSHA requires emergency action plans to include procedures for evacuation and a method for accounting for all employees after evacuation.
Question 5: In a risk matrix, a hazard rated as 'high likelihood' and 'minor severity' would typically fall into which risk category?
- Critical
- High
- Medium (Correct answer)
- Low
Correct answer: Medium
High frequency combined with low severity typically yields a medium risk rating, requiring planned corrective action.
Question 6: Which of the following best describes 'inherently safer design' (ISD)?
- Adding redundant safety systems to existing equipment
- Eliminating or reducing hazards at the design stage rather than adding controls (Correct answer)
- Issuing additional PPE to workers near hazardous equipment
- Posting warning signs in hazardous areas
Correct answer: Eliminating or reducing hazards at the design stage rather than adding controls
ISD focuses on permanently eliminating or minimizing hazards by changing the process or material during design, not adding protective layers.
Question 7: According to OSHA, which of the following must be included in a written Hazard Communication (HazCom) program?
- A list of all chemical manufacturers used
- Methods for labeling containers and employee training on SDS (Correct answer)
- Monthly chemical usage reports
- Annual third-party chemical audits
Correct answer: Methods for labeling containers and employee training on SDS
OSHA 29 CFR 1910.1200 requires the HazCom program to describe labeling systems, SDS management, and employee training methods.
A quantitative risk assessment assigns a numerical probability to hazard events.
