1. What is the primary purpose of a blasting safety program?
a. To increase production speed
b. To reduce paperwork
c. To prevent injuries, property damage, and unintended detonations
d. To eliminate the need for supervision
Rationale: A blasting safety program establishes controls intended to
protect workers, the public, property, and the environment. Because
explosives present unusually severe hazards, prevention and risk
control are the central objectives.
2. Which principle is most important when an explosive-related
hazard is identified?
a. Continue work if production is behind schedule
b. Stop or control the hazardous activity until the hazard is properly
addressed
,c. Allow untrained workers to investigate
d. Ignore the hazard if no injury has occurred

exposed. Work should be stopped or appropriately controlled when
conditions could create an unacceptable risk.
3. Who should be permitted to perform specialized explosive-
related duties?
a. Any available construction worker
b. A visitor who has observed blasting before
c. Personnel who are properly authorized, trained, and qualified for
the duty

experience
Rationale: Explosives work requires specialized competence and
authorization. General construction experience does not by itself
qualify someone to perform specialized explosive-related duties.

operations?
a. To provide additional storage space
b. To improve equipment access
,c. To keep unauthorized people away from a potentially hazardous

associated with blasting. Effective access control is a fundamental
component of public and worker protection.

blasting-related work proceeds?
a. A minor scheduling delay
b. A shortage of office supplies
c. Unauthorized persons entering a controlled area
d. A dirty company vehicle
Rationale: Unauthorized entry can expose people to serious hazards.
Access control must therefore be maintained before hazardous
operations are permitted to proceed.

around blasting activities?
a. They primarily improve advertising
b. They eliminate all legal requirements
c. They help ensure affected personnel understand when hazardous
, operations are occurring
d. They replace the need for trained personnel
Rationale: Clear communication reduces the possibility that workers,
visitors, or members of the public will unknowingly enter a hazardous
area.
7. Which document is most useful for identifying the hazards and
controls associated with a particular job?
a. Employee vacation schedule
b. Sales brochure
c. Job hazard analysis or equivalent risk assessment
d. Company advertisement
Rationale: A job hazard analysis systematically identifies hazards and
establishes appropriate controls. It helps workers understand risks
before work begins.
8. What is the safest response when an employee does not
understand a required safety procedure?
a. Tell the employee to copy another worker
b. Have the employee proceed anyway
c. Provide appropriate instruction and clarification before the task is
