Read the first 7 Hazard Recognition and Control flashcards as text

  1. When conducting a Failure Mode and Effects Analysis (FMEA), what does 'detectability' refer to?

    Answer: The ability to detect a failure before it causes harm

    In FMEA, detectability rates how easily a failure mode can be identified before it results in an adverse effect.

  2. An employee working outdoors in summer reports dizziness, nausea, and hot, dry skin. Which heat illness is MOST likely occurring?

    Answer: Heat stroke

    Hot, dry skin combined with dizziness and nausea indicates heat stroke, a life-threatening emergency requiring immediate cooling.

  3. What is the purpose of a 'pre-task plan' (also called a tailgate or toolbox talk) in hazard recognition?

    Answer: Identify hazards specific to today's work before starting

    Pre-task plans are brief meetings held before work begins to identify site-specific hazards and control measures for that day's tasks.

  4. Which biological hazard is associated with standing water and cooling towers in workplaces?

    Answer: Legionella pneumophila

    Legionella pneumophila thrives in warm standing water and building water systems, causing Legionnaires' disease when aerosolized.

  5. A safety specialist is reviewing a facility where workers are exposed to hand-arm vibration from power tools. Which health effect is MOST associated with chronic exposure?

    Answer: Vibration white finger (Raynaud's phenomenon)

    Chronic hand-arm vibration exposure causes vibration-induced white finger (VWF), a vascular disorder affecting blood flow to the fingers.

  6. Under OSHA's Lockout/Tagout standard, which energy source is specifically exempt from LOTO procedures when under normal production conditions?

    Answer: Normal production operations using machine guards as specified in the standard

    OSHA's LOTO standard (1910.147) does not apply during normal production when machines are properly guarded as required by other applicable standards.

  7. A safety specialist identifies that workers frequently bypass a machine safety interlock to speed up production. Which root cause category does this behavior BEST represent?

    Answer: Management system failure

    Bypassing safety interlocks due to production pressure reflects a management system failure in enforcement, culture, and hazard communication.
