1. What is the primary purpose of an industrial contractor’s project
safety plan?
A. To reduce material costs
B. To establish procedures for identifying and controlling hazards
C. To eliminate the need for worker training
D. To determine the contractor’s profit margin
Answer: B. To establish procedures for identifying and controlling
hazards
Rationale: A project safety plan provides a structured approach for
recognizing hazards, implementing controls, assigning responsibilities,
and protecting workers throughout industrial construction activities.
, 2. Before beginning excavation around an existing industrial facility,
what should be done first?
A. Begin excavation with a small excavator
B. Remove all surface vegetation
C. Locate and identify existing underground utilities
D. Install permanent piping
Answer: C. Locate and identify existing underground utilities
Rationale: Existing underground utilities must be located before
excavation to prevent damage to electrical, gas, water, communication,
sewer, or process systems and to protect workers from potentially
severe hazards.
3. What is the main function of a lockout/tagout procedure?
A. To improve equipment production rates
B. To prevent unexpected energization or startup of equipment
C. To identify equipment manufacturers
D. To determine equipment warranty periods
Answer: B. To prevent unexpected energization or startup of
equipment
,Rationale: Lockout/tagout controls hazardous energy sources while
