A new supervisor wants to ensure their team is properly trained on the hazards associated with a new chemical being introduced to the workplace. What is the supervisor's most critical responsibility in this situation?
Answer: To ensure all employees have access to the SDS and receive training on its contents.
Under OSHA's Hazard Communication Standard, employers (and their representatives, like supervisors) must ensure that employees are trained on the hazards of chemicals they work with. This includes understanding the information contained within the Safety Data Sheet (SDS). While a senior member might assist, the supervisor is ultimately responsible for ensuring the training happens and that the SDS is accessible.
A supervisor is leading a team to develop a JSA for changing a flat tire on a delivery truck. When breaking the job down into distinct steps, what is a key principle they should follow?
Answer: Keep the sequence of steps in the correct order of occurrence.
Breaking a job down into its sequential steps is a critical part of the JSA process. Maintaining the correct order is essential to accurately identify how hazards are introduced and how one step might affect the safety of the next. Steps should be distinct but not overly detailed.
Which jobs should be prioritized for JSA?
Answer: Jobs with high injury frequency, severity potential, or that are new, complex, or non-routine
Priority goes to high injury rates, severe potential, and new or non-routine jobs.
What is the maximum free fall distance with a personal fall arrest system?
Answer: 6 feet
OSHA limits maximum free fall to 6 feet with a personal fall arrest system.
A manufacturing facility installs a local exhaust ventilation (LEV) system to capture welding fumes at the source. This is an example of what type of hazard control?
Answer: Engineering Control
Engineering controls are physical changes to the work environment or equipment to isolate workers from hazards. A local exhaust ventilation system is a prime example of an engineering control because it physically removes the hazardous fumes from the breathing zone of the worker.
What is the primary purpose of a safety observation program?
Answer: To identify unsafe behaviors and conditions before they cause injury
Safety observation programs proactively identify at-risk behaviors and hazardous conditions so corrective action can occur before an incident.
What is the primary difference between a hazard and a risk?
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.
A Safety Data Sheet (SDS) section that identifies the physical and chemical properties of a hazardous substance is found in which section?
Answer: Section 9
Section 9 of a GHS-aligned Safety Data Sheet covers Physical and Chemical Properties, including appearance, odor, pH, boiling point, flash point, and flammability. OSHA's Hazard Communication Standard (29 CFR 1910.1200) requires the 16-section SDS format.
What should a site supervisor do FIRST when discovering an imminent danger?
Answer: Immediately remove or protect workers from the danger
The first priority is immediately removing workers from or protecting them against the danger.
Which method of hazard control is considered MOST effective according to the hierarchy of controls?
Answer: Elimination of the hazard
Elimination removes the hazard entirely and is the most effective control at the top of the hierarchy.
What is the difference between hazard prevention and mitigation?
Answer: Prevention stops harm from occurring; mitigation reduces severity of consequences after an incident
Prevention stops incidents from occurring; mitigation reduces consequences if they do occur.
A supervisor at a new worksite observes a portable fire extinguisher with a symbol depicting a trash can and a wood pile on fire. This extinguisher is rated for which class of fire?
Answer: Class A
Class A fires involve ordinary combustible materials such as paper, wood, cloth, and some plastics. The pictograph for a Class A fire extinguisher shows a fire in a trash can and a wood pile. Supervisors must ensure the correct type of extinguisher is available for the potential fire hazards present.
What most effectively promotes a positive safety culture on site?
Answer: Consistently demonstrating safe behaviors, recognizing safe practices, and holding everyone accountable
Leading by example, recognizing safe behaviors, and consistent accountability build positive safety culture.
A supervisor is interviewing a witness to a serious incident. Which of the following is the MOST effective technique to gather accurate, unbiased information?
Answer: Conduct the interview in a private setting and ask open-ended questions.
To get the most accurate and untainted account, witnesses should be interviewed individually in a private, non-threatening environment. Asking open-ended questions (e.g., "Tell me what you saw") encourages the witness to provide a detailed narrative in their own words without influence or bias.
When a worker is exposed to a noise level of 90 dBA, OSHA's hearing conservation standard requires a hearing conservation program if that exposure lasts for:
Answer: 8 hours per day (the full workday)
OSHA's permissible exposure limit for noise is 90 dBA for an 8-hour time-weighted average before a full conservation program is mandated at that level.
What are the three basic steps in a Job Safety Analysis?
Answer: Break job into steps, identify hazards for each step, develop preventive measures
JSA involves breaking the job into steps, identifying hazards, and developing preventive measures.
According to OSHA 29 CFR 1926.502, what is the minimum strength requirement for a non-certified anchorage point used for a personal fall arrest system (PFAS)?
Answer: 5,000 pounds per employee attached.
OSHA's standard for fall protection in construction, 29 CFR 1926.502(d)(15), explicitly states that anchorages used for personal fall arrest equipment shall be capable of supporting at least 5,000 pounds per employee attached, or be designed and installed as part of a complete system that maintains a safety factor of at least two under the supervision of a qualified person.
How should controls be validated after implementation?
Answer: Through monitoring, measurement, testing, and periodic review
Validation requires ongoing monitoring, measurement, and review to verify effectiveness.
Lockout/Tagout (LOTO) procedures are primarily designed to protect workers from:
Answer: Unexpected energization or release of stored energy
LOTO procedures control hazardous energy — electrical, mechanical, hydraulic, pneumatic — to prevent unexpected startup during servicing.
After ensuring an injured employee receives medical attention and the area is safe, what is the most critical next step for a supervisor in the incident investigation process?
Answer: Secure the incident scene to preserve evidence.
Immediately after addressing personnel safety and medical needs, the supervisor must secure the incident scene. This prevents evidence from being moved, altered, or destroyed, which is crucial for conducting an accurate investigation to determine the root causes.
