NH BLASTING LICENSE 2025/2026 QUESTIONS WITH 100% PASSED ANSWERS &
WELL DETAILED RATIONALES/GRADE A+ ASSURED !!
Question 1
Under New Hampshire blasting regulations, which category of certificate of competency allows
for all types of commercial blasting work without restriction?
A) Specialized certificate
B) Agricultural certificate
C) Restricted certificate
D) Certificate with no restrictions
E) Municipal certificate
Correct Answer: D) Certificate with no restrictions
Rationale: According to Saf-C 1603.01(a)(1), a certificate with no restrictions is the highest
tier of competency, specifically allowing the holder to engage in all types of commercial
blasting work throughout the state. The other categories mentioned serve to limit the scope
of work to specific agencies, materials, or agricultural purposes.
Question 2
What is the maximum amount of explosives allowed per detonation for a holder of a restricted
certificate of competency?
A) 25 pounds
B) 50 pounds
C) 100 pounds
D) 250 pounds
E) 500 pounds
Correct Answer: C) 100 pounds
Rationale: Per Saf-C 1603.01(b), a restricted certificate of competency is legally limited to a
maximum of 100 pounds of explosives per detonation. This restriction ensures that blasters
who do not hold a full, unrestricted license are not handling massive quantities of explosive
materials in a single event.
Question 3
What is the maximum explosive limit per detonation for an agricultural certificate of
competency?
A) 10 pounds
B) 25 pounds
C) 50 pounds
D) 75 pounds
E) 100 pounds
Correct Answer: C) 50 pounds
Rationale: Saf-C 1603.01(c) explicitly limits the use of explosives for those holding an
, 2
agricultural certificate to 50 pounds per detonation. This certificate is designed for non-
commercial farm improvements such as stump removal, where smaller quantities are
typically sufficient.
Question 4
A specialized certificate of competency is restricted to which of the following?
A) Municipal employees only
B) Non-commercial agricultural work
C) Only 100 pounds of TNT
D) Specific materials or uses, such as black powder or blasting caps only
E) Blasting performed only during daylight hours
Correct Answer: D) Specific materials or use, such as blasting caps or black powder only
Rationale: Saf-C 1603.01(a)(4) defines specialized certificates as those restricted to specific
materials or uses outlined on the certificate itself. This allows for niche expertise or limited
use-cases where a full commercial license is unnecessary but safety standards must still be
met for specific materials like black powder.
Question 5
How long must a licensee keep a record of all transactions or operations involving explosive
materials?
A) 1 year
B) 2 years
C) 3 years
D) 5 years
E) 10 years
Correct Answer: D) 5 years
Rationale: Pursuant to Saf-C 1607.02(a) and Saf-C 1607.03(d), New Hampshire law requires
each licensee to maintain records of all transactions, operations, and disposals for a
minimum period of 5 years. These must be made available to the director upon request for
auditing and safety tracking purposes.
Question 6
Which of the following documents may satisfy the requirement for transaction records if they
include the receiver's signature?
A) Employee timecards
B) Marketing reports
C) Accumulation of invoices, sales slips, or delivery tickets
D) Pre-blast inspection logs
E) Personal diaries of the blaster

Correct Answer: C) An accumulation of invoices, sales slips, delivery tickets or receipts, or
similar papers
Rationale: Saf-C 1607.02(b) states that records of transactions are satisfied by maintaining
papers such as invoices or delivery tickets, provided they contain the signature of the
receiver. This ensures a verifiable chain of custody for explosive materials entering or
leaving a facility.
Question 7
Marketing reports for explosive materials sold within New Hampshire must be submitted to the
director on which form?
A) DSSP 100
B) DSSP 125
C) NH-BLAST-1
D) Form 1607-B
E) ATF Form 4
Correct Answer: B) DSSP 125
Rationale: Saf-C 1607.01(b) mandates that any person who sells or markets explosives in the
state must submit a monthly "Explosives Marketing Report" using form DSSP 125. This
allows the State to monitor the commercial flow of dangerous materials.
Question 8
By what day of the month must the monthly marketing report be submitted to the director?
A) The 1st day
B) The 5th day
C) The 10th day
D) The 15th day
E) The last day
Correct Answer: D) the 15th day of each month
Rationale: Saf-C 1607.01(b) specifies that the marketing report must be submitted no later
than the 15th day of each month for the preceding month's activities. Timely reporting is
essential for effective regulatory oversight.
Question 9
What information must be included in the daily log of explosive materials fired or disposed of?
A) The cost of the explosives
B) The GPS coordinates of the store
C) The manufacturer's name, type, size, and identification number
D) The name of the insurance carrier
E) The weather conditions during the disposal
, 4
Correct Answer: C) The manufacturer's name; and the type, size and identification number
of the explosives
Rationale: Saf-C 1607.03(b)(1) requires a daily log for disposals that tracks the specific
manufacturer and identification details of the explosives. This granular data is vital for
tracing materials in the event of a malfunction or theft.
Question 10
A record of each blast must be completed at what specific time?
A) 24 hours before the blast
B) Within one week of the blast
C) Prior to or immediately following detonation
D) Only if an accident occurs
E) At the end of the fiscal year
Correct Answer: C) prior to or immediately following detonation
Rationale: Saf-C 1607.03(b)(2) requires the blast record to be created either immediately
before or immediately after the event. This prevents "memory-based" errors in reporting
and ensures accurate logging of the amount of explosives used and the timing of the
initiators.
Question 11
Which of the following must be included in the record of a completed blast?
A) The color of the detonation cord
B) The name and certificate number of the person setting off the blast
C) The brand of the truck used for transport
D) The total cost of the project
E) The distance to the nearest state border
Correct Answer: B) Name and certificate of competency number of person setting off blast
Rationale: Saf-C 1607.03(b)(2)a requires the individual blaster's identification and
certificate number to be recorded. This ensures accountability, verifying that only a
qualified person with a valid certificate of competency performed the detonation.
Question 12
What specific measurement regarding drill holes must be recorded for each blast?
A) The weight of the drill rig
B) The angle of the sun at the time of drilling
C) The diameter of each hole and the distance between the last explosive and the surface
D) The color of the stemming material
E) The depth of the water table
