PIC Safety Regulations & Documentation Practices 3 — Questions and Answers
Question 1: A flagging operation is required when temporary traffic control must be maintained. Which MUTCD requirement applies to flaggers regarding positioning?
- Flaggers must stand in the center of the travel lane at all times
- Flaggers must be positioned where they can be seen by approaching traffic for adequate stopping distance (Correct answer)
- Flaggers may position themselves wherever is most comfortable
- Flaggers must stand behind concrete barriers only
Correct answer: Flaggers must be positioned where they can be seen by approaching traffic for adequate stopping distance
MUTCD Part 6E requires flaggers to be positioned where they have adequate sight distance and can be seen by motorists in time to stop safely.
Question 2: Which regulation governs the handling and disposal of petroleum-contaminated millings generated during asphalt removal?
- OSHA 29 CFR 1910.1200 (Hazard Communication)
- EPA RCRA regulations for hazardous waste (Correct answer)
- MUTCD Part 6 work zone standards
- AASHTO bridge design specifications
Correct answer: EPA RCRA regulations for hazardous waste
Petroleum-contaminated millings may be classified as hazardous waste under EPA's Resource Conservation and Recovery Act (RCRA) regulations.
Question 3: A contractor's worker is observed not wearing required PPE. The paving inspector's FIRST action should be to:
- Immediately shut down the entire project
- Notify the contractor's superintendent and document the observation (Correct answer)
- Directly discipline the worker on the contractor's behalf
- Ignore the violation if it is a minor infraction
Correct answer: Notify the contractor's superintendent and document the observation
Inspectors notify the contractor's superintendent of safety violations and document them; direct discipline of contractor employees is outside the inspector's authority.
Question 4: What is the purpose of a pre-activity safety briefing (toolbox talk) before paving operations begin?
- To review project billing and payment schedules
- To identify daily hazards, review safe work procedures, and ensure all workers are informed of risks (Correct answer)
- To formally transfer liability from the contractor to the owner
- To satisfy MUTCD Part 6 signing requirements
Correct answer: To identify daily hazards, review safe work procedures, and ensure all workers are informed of risks
Toolbox talks ensure all workers understand daily hazards and safe procedures before work begins, reducing incident risk.
Question 5: On a federally funded highway project, which form is typically used to document material acceptance by testing?
- FHWA Form 1273 compliance checklist
- Material Certification and Test Report (or equivalent agency QA form) (Correct answer)
- Daily Inspector's Diary only
- Contractor's pay estimate form
Correct answer: Material Certification and Test Report (or equivalent agency QA form)
Material acceptance is documented on a Material Certification and Test Report (or the owning agency's equivalent QA/QC acceptance form).
Question 6: During milling operations, a cloud of asphalt dust is generated. Which health hazard is of PRIMARY concern for workers?
- Noise from the milling machine
- Silica and respirable dust exposure leading to respiratory disease (Correct answer)
- UV radiation from sunlight
- Contact dermatitis from hydraulic fluid
Correct answer: Silica and respirable dust exposure leading to respiratory disease
Asphalt milling dust can contain respirable crystalline silica, which causes silicosis and other serious lung diseases with prolonged exposure.
Question 7: Which regulation requires contractors on federally assisted highway projects to maintain OSHA Form 300 injury and illness logs?
- FHWA Form 1273, Required Contract Provisions
- OSHA 29 CFR 1904, Recording and Reporting Occupational Injuries and Illnesses (Correct answer)
- MUTCD Part 6, Temporary Traffic Control
- AASHTO M 17 specification
Correct answer: OSHA 29 CFR 1904, Recording and Reporting Occupational Injuries and Illnesses
OSHA 29 CFR 1904 mandates employers to record work-related injuries and illnesses on the OSHA 300 log.
