HSE Workplace Safety Management and Risk Control 2 — Questions and Answers
Question 1: Which risk control method is considered most effective in the hierarchy of controls?
- Administrative controls
- Personal protective equipment
- Engineering controls
- Elimination of the hazard (Correct answer)
Correct answer: Elimination of the hazard
Elimination removes the hazard entirely and is the highest level of control in the hierarchy.
Question 2: A Job Hazard Analysis (JHA) is BEST conducted at which point in a project lifecycle?
- After the first incident occurs
- During the planning phase before work begins (Correct answer)
- At the end of the project for documentation
- Only when OSHA requires it
Correct answer: During the planning phase before work begins
Conducting a JHA during planning allows hazards to be designed out or controlled before workers are exposed.
Question 3: What does the acronym 'LOTO' stand for in workplace safety?
- Limit Operations, Test Output
- Lockout/Tagout (Correct answer)
- Load Out, Transfer Out
- Lock On, Tag On
Correct answer: Lockout/Tagout
Lockout/Tagout (LOTO) procedures control hazardous energy during equipment servicing and maintenance.
Question 4: Which document formally assigns safety responsibilities to line managers and supervisors?
- Risk register
- Safety policy statement (Correct answer)
- Incident investigation report
- Training matrix
Correct answer: Safety policy statement
A safety policy statement defines organizational commitments and assigns responsibilities throughout the management hierarchy.
Question 5: In a bow-tie risk model, what does the 'left side' (before the top event) represent?
- Consequences of the incident
- Recovery measures after the event
- Threats and preventive barriers (Correct answer)
- Corrective action plans
Correct answer: Threats and preventive barriers
The left side of a bow-tie diagram shows threats and the preventive controls that stop them from causing the top event.
Question 6: Under OSHA 29 CFR 1910.132, employers must provide PPE at what cost to the employee?
- Employees pay for consumable PPE only
- No cost to the employee (Correct answer)
- Shared cost between employer and employee
- Full cost borne by the employee
Correct answer: No cost to the employee
OSHA requires employers to provide required PPE at no cost to workers, with limited exceptions for everyday clothing.
Question 7: What is the primary purpose of a management of change (MOC) process in a safety management system?
- To document completed safety training
- To ensure changes in processes, equipment, or personnel are evaluated for new hazards (Correct answer)
- To track equipment maintenance schedules
- To record near-miss events
Correct answer: To ensure changes in processes, equipment, or personnel are evaluated for new hazards
MOC ensures that any change is reviewed before implementation so new or modified hazards can be identified and controlled.
