CFB Safety & Compliance Standards 3 — Questions and Answers
Question 1: Which ASTM standard is most commonly referenced for specifying the quality of steel pipe used in field utility installations?
- ASTM A53 (Correct answer)
- ASTM D3034
- ASTM C76
- ASTM A615
Correct answer: ASTM A53
ASTM A53 covers seamless and welded black and galvanized steel pipe used in pressure and mechanical applications on construction sites.
Question 2: What is the primary purpose of a Job Hazard Analysis (JHA) in field construction?
- To identify hazards for each task before work begins (Correct answer)
- To document injuries after they have occurred
- To estimate the cost of safety equipment
- To assign liability in the event of an accident
Correct answer: To identify hazards for each task before work begins
A JHA breaks each job task into steps and identifies associated hazards so that controls can be implemented before work starts.
Question 3: When is a Safety Data Sheet (SDS) required to be updated by the chemical manufacturer?
- Within 3 months of new hazard information becoming available (Correct answer)
- Every calendar year regardless of changes
- Only when requested by the employer
- After every 500 units sold
Correct answer: Within 3 months of new hazard information becoming available
Under OSHA's HazCom 2012 (GHS-aligned), manufacturers must update SDSs within 3 months of discovering significant new hazard information.
Question 4: In field construction, what does 'LOTO' stand for and what is its purpose?
- Lockout/Tagout — isolating energy sources to prevent accidental machine startup (Correct answer)
- Locate/Test/Operate — a startup checklist for heavy equipment
- Lift/Transfer/Offload — crane operation protocol
- Label/Organize/Track/Observe — material management system
Correct answer: Lockout/Tagout — isolating energy sources to prevent accidental machine startup
Lockout/Tagout (OSHA 29 CFR 1910.147) requires de-energizing and physically locking equipment before maintenance to prevent unexpected energization.
Question 5: A newly installed field drainage system must be pressure-tested. Which standard most likely governs the testing procedure for PVC pressure pipe?
- ASTM D2774 (Correct answer)
- ASTM E119
- ANSI A13.1
- NFPA 13
Correct answer: ASTM D2774
ASTM D2774 provides standard practice for underground installation and pressure testing of thermoplastic (PVC) pressure piping systems.
Question 6: What is the maximum allowable slope (rise:run) for a temporary access ramp used by workers on a field construction site?
- 1:3 (approximately 18 degrees) (Correct answer)
- 1:1 (45 degrees)
- 1:6 (approximately 10 degrees)
- 1:12 (approximately 5 degrees)
Correct answer: 1:3 (approximately 18 degrees)
OSHA allows temporary ramps for workers up to approximately 18 degrees (1:3 slope) before additional safety measures such as cleats are required.
Question 7: Which government agency enforces environmental compliance standards on field construction sites, including stormwater runoff controls?
- Environmental Protection Agency (EPA) (Correct answer)
- Occupational Safety and Health Administration (OSHA)
- Federal Highway Administration (FHWA)
- Army Corps of Engineers (USACE)
Correct answer: Environmental Protection Agency (EPA)
The EPA enforces the Clean Water Act's NPDES permit program, which requires stormwater pollution prevention plans (SWPPPs) on construction sites.
