Mixed Deck — All NSC Topics Flashcards

In fire safety, what does 'fire triangle' refer to?

Answer: Heat, fuel, and oxygen

The fire triangle consists of heat, fuel, and oxygen — removing any one element extinguishes the fire.

Under OSHA's Hazard Communication Standard (HazCom), how many sections must a Safety Data Sheet (SDS) contain?

Answer: 16

OSHA's HazCom Standard (29 CFR 1910.1200) requires SDSs to follow a standardized 16-section format aligned with the GHS.

What is the most reliable way to confirm correct endotracheal tube placement?

Answer: Waveform capnography showing continuous CO2 detection

Waveform capnography is the gold standard for confirming ET tube placement because it continuously detects exhaled CO2 from the lungs.

A safety professional notices workers are drowsy after eating at the cafeteria. Which cafeteria change would best address post-meal drowsiness?

Answer: Reducing refined carbohydrates and increasing fiber and protein

High-glycemic refined carbohydrates cause rapid blood sugar spikes followed by crashes; replacing them with fiber and protein promotes steadier energy levels.

Which control measure most effectively protects pedestrians near loading docks where forklifts operate?

Answer: Installing physical barriers or guardrails

Physical barriers and guardrails provide passive, continuous protection that prevents pedestrians from accidentally entering the forklift zone regardless of human behavior.

What is the primary purpose of a 'Toolbox Talk'?

Answer: To conduct a brief worksite safety discussion on the day's hazards

A Toolbox Talk is a short, informal safety meeting focused on hazards specific to the tasks planned for that day.

Which fluid should NOT be topped off by the operator and must be handled only by qualified maintenance personnel?

Answer: Both B and C

Brake fluid and pressurized coolant systems require qualified maintenance personnel due to safety risks and system-specific procedures.

What is the purpose of a post-project debrief in forklift operations management?

Answer: To document lessons learned and identify planning improvements for future projects

Post-project debriefs capture what worked, what didn't, and what can be improved, building institutional knowledge that makes future forklift projects safer and more efficient.

What does the 'B' in the CAGE questionnaire stand for?

Answer: Blackout

CAGE stands for Cut down, Annoyed, Guilty, and Eye-opener — 'B' is not part of the acronym; 'Blackout' is a distractor.

During a clinical evaluation, a client denies substance use but shows constricted pupils and track marks. What is this discrepancy called?

Answer: Incongruence between self-report and clinical signs

When objective physical findings contradict a client's self-report, this is documented as incongruence and requires further assessment.

In NSC certification, what is the primary purpose of regulatory compliance programs?

Answer: To ensure adherence to laws and standards

Regulatory compliance programs are designed to ensure organizations follow applicable laws, regulations, and standards.

A propane-powered forklift's gas cylinder shows frost on the exterior during operation. What does this indicate?

Answer: The cylinder is being used too quickly or has a regulator issue requiring inspection

Frost on an LPG cylinder during operation indicates excessive withdrawal rate or a regulator issue that must be inspected by qualified personnel.

Of the following, only one is untrue regarding a low serum albumin level?

Answer: It may be used to diagnosis esophageal reflux

Low serum albumin is a common finding in conditions like nephrotic syndrome (due to protein loss), kwashiorkor (severe protein malnutrition), and ascites (due to reduced oncotic pressure). However, serum albumin levels are not a diagnostic marker for esophageal reflux. Esophageal reflux is typically diagnosed based on symptoms, endoscopy, or pH monitoring.

What safety step must be taken before inspecting the underside of a forklift with the mast elevated?

Answer: Lower the mast fully or secure it with safety props to prevent accidental lowering

The mast must be lowered or secured with safety props before any inspection underneath it to prevent crush injuries from accidental lowering.

Which of the following represents a key limitation of PPE that workers and safety professionals must understand?

Answer: PPE only protects the wearer and does not reduce or control the hazard itself

PPE does not eliminate or reduce the hazard — it only creates a barrier between the worker and the hazard, which is why it is considered the last resort in the hierarchy of controls.

Why is it important to check the forklift’s tires regularly?

Answer: To ensure proper traction and stability.

Forklift tires are vital for maintaining stability, especially when carrying heavy loads or operating on uneven surfaces. Worn, damaged, or improperly inflated tires can compromise traction, increase the risk of tipping, and affect braking performance. Regular checks ensure the tires provide the necessary grip and support for safe and stable operation, preventing accidents and ensuring efficient material handling.

How often are building codes typically updated?

Answer: Every three years through a formal code development cycle

Model building codes are updated every three years through a formal development cycle that incorporates new research, technology, and lessons learned.

Which component of a personal fall arrest system (PFAS) absorbs energy and limits the force on the worker during a fall?

Answer: Shock-absorbing lanyard

A shock-absorbing lanyard contains a deceleration device that deploys during a fall, extending the stop distance and reducing peak arrest forces.

What is the correct method for disposing of a small amount of used solvent-soaked rags in the workplace?

Answer: Place them in a self-closing, approved flammable waste container

Solvent-soaked rags must be stored in self-closing, approved flammable waste containers to prevent spontaneous combustion and fire hazards.

When checking forklift battery fluid levels, which safety precautions are necessary?

Answer: Wear gloves and eye protection, keep flames away from the battery area

Battery acid is corrosive and batteries emit hydrogen gas, so PPE and no-flame rules are essential when checking fluid levels.
