25 feet
75 feet
100 feet
55 feet
OSHA requires that an emergency eyewash station be located within a 10-second travel distance from the hazard, which is generally interpreted as a maximum of 55 feet. This ensures prompt decontamination of the eyes. Stations must also deliver tepid water for at least 15 minutes. .
Which agency publishes the Hazard Communication Standard?
ANSI
OSHA
NIOSH
EPA
The U.S. Occupational Safety and Health Administration (OSHA) issues the Hazard Communication Standard (HCS) to ensure information about chemical hazards is disseminated to workers. It aligns with the Globally Harmonized System (GHS) for classification and labeling. Employers must comply by providing labels and Safety Data Sheets. .

Cotton balls in ears
Noise-cancelling earmuffs
Single-use ear swabs
Hard hats
For noise levels at or above 85 dB, OSHA requires employers to implement hearing conservation, including the use of hearing protection devices. Noise-cancelling earmuffs typically provide higher Noise Reduction Ratings (NRR) and are recommended in high-noise environments. Proper fit and maintenance are critical. .
In an ergonomic assessment, what does RULA stand for?
Rapid Upper Limb Assessment
Recommended Usage Load Assessment
Rapid User Load Assessment
Regular Upper Limit Analysis
RULA stands for Rapid Upper Limb Assessment, an ergonomic tool used to evaluate postural risks in the neck, trunk, and upper limbs. It helps identify activities that might lead to musculoskeletal disorders. Scores guide decisions on redesigning tasks or controls. .
What is the required frequency for retraining OSHA-certified forklift operators?
Only initial training
Every three years
Annually
Monthly
OSHA requires formal evaluation of forklift operators at least once every three years to ensure safe operation. Employers must provide refresher training sooner if an operator demonstrates unsafe behavior, is involved in an accident, or if workplace conditions change. .
What is the first step in a proper Lockout/Tagout (LOTO) procedure?
Apply the lock
Notify affected employees
Shut down equipment
Isolate energy source
The first step in LOTO is to notify all affected employees that the equipment will be shut down and locked out for servicing. This communication prevents accidental startup. Subsequent steps include shutting down, isolating energy, applying locks, and verifying zero energy. .
On an NFPA 704 diamond, what does the blue quadrant represent?
Flammability
Reactivity

Cheat Sheet

  1. Hierarchy of Controls -

    The hierarchy of controls ranks hazard reduction methods from most to least effective: Elimination, Substitution, Engineering Controls, Administrative Controls, and PPE. A handy mnemonic is "ESEAP" to recall the sequence when preparing for a workplace safety quiz with answers. By focusing on higher”level controls first, you substantially lower risk before relying on personal protective equipment (NIOSH, 2021).

  2. OSHA Standards Overview -

    Key OSHA safety quiz questions often reference 29 CFR 1910 for general industry and 29 CFR 1926 for construction. Familiarize yourself with the General Duty Clause (Section 5(a)(1)), which mandates a workplace "free from recognized hazards." Reviewing sample CFR excerpts from osha.gov sharpens your regulatory recall for any safety regulation quiz.

  3. Hazard Communication & GHS -

    Under OSHA's HazCom standard (29 CFR 1910.1200), employees must understand Safety Data Sheets (SDS) and nine GHS pictograms. A simple trick: "LABEL SDS" reminds you to Learn, Assess, Be aware, Evaluate Labels, Seek Data, and Stay safe. Mastering these symbols and SDS sections boosts your score on any workplace hazard quiz.

  4. PPE Selection and Levels -

    Selecting proper PPE depends on hazard type and exposure level; for chemical response, know Levels A - D: Level A being fully encapsulated suits and Level D everyday work attire. Always perform a fit test for respirators and inspect PPE for defects before use. OSHA training modules provide real”world scenarios that often appear in PPE”focused quiz questions.

  5. Emergency Response Mnemonics -

    Emergency drills and quizzes test your recall of RACE (Rescue, Alarm, Contain, Extinguish) and PASS (Pull, Aim, Squeeze, Sweep) for fire extinguishers. Practice these steps in mock drills to build muscle memory and confidence. According to the National Fire Protection Association (NFPA 10), correct use of RACE and PASS reduces response time and prevents minor incidents from escalating.
