1. What is the primary purpose of a site-specific safety plan on an
oilfield construction project?
a. To establish the project's profit margin
b. To replace all manufacturer instructions
c. To identify project hazards and establish controls for safe work
d. To eliminate the need for worker training
Rationale: A site-specific safety plan identifies hazards associated with
the actual worksite and establishes procedures, responsibilities, and
controls to reduce the likelihood and severity of incidents. It
complements, rather than replaces, training, regulations, and
manufacturer requirements.
,2. Before excavation begins near an existing pipeline, what should be
done first?
a. Begin mechanical excavation slowly
b. Increase the excavation depth gradually
c. Determine the location of existing underground utilities and
pipelines
d. Remove all nearby warning signs
Rationale: Existing underground facilities must be identified before
excavation. Locating and marking utilities helps prevent strikes that
could cause releases, fires, explosions, service interruptions, or serious
injuries.
3. What is the main purpose of a permit-to-work system in oilfield
construction?
a. To document employee vacation schedules
b. To calculate equipment depreciation
c. To control hazardous work through authorization and defined
precautions
d. To replace the project's construction drawings
Rationale: Permit-to-work systems provide formal authorization for
specific hazardous activities. They help ensure that hazards have been
assessed and required precautions are in place before work begins.
,4. Which instrument is commonly used to test an atmosphere for
oxygen deficiency and combustible gases?
a. Tape measure
b. Portable gas detector
c. Torque wrench
d. Pressure gauge only
Rationale: Portable gas detectors can be configured to measure
oxygen concentration and combustible or toxic gases. Atmospheric
testing is especially important before and during work in potentially
hazardous areas.
5. What does a high reading on the combustible-gas scale of a
properly calibrated gas detector generally indicate?
a. Excessive oxygen concentration
b. Low atmospheric pressure
c. The presence of a potentially flammable concentration of gas or
vapor
d. High water content in the soil
Rationale: Combustible-gas detectors indicate the concentration of
flammable gas or vapor relative to its lower explosive limit.
Appropriate action depends on the measured concentration and site
procedures.
, 6. What is the primary function of a pressure relief device on a
pressurized system?
a. Increase operating pressure
b. Prevent corrosion
c. Protect the system from excessive pressure
d. Measure fluid temperature
Rationale: Pressure relief devices are designed to discharge or
otherwise control pressure when it reaches a predetermined level.
This helps protect piping, vessels, and associated equipment from
overpressure.
7. Why are process lines isolated before certain maintenance
activities?
a. To improve paint adhesion
b. To reduce paperwork
c. To prevent unexpected flow or energy release into the work area
d. To increase the line's operating pressure
Rationale: Isolation separates workers and equipment from hazardous
energy or process materials. Effective isolation is a fundamental part
of safe maintenance and construction work on operating facilities.
8. What is the purpose of lockout/tagout procedures?
