What is the correct procedure when a blaster discovers a 'bootleg' (unbroken rock remaining above an unexploded charge)?
Answer: Follow misfire procedures: wait the required time, then stem and water-flush the bootleg or fire a relief hole parallel to and at safe offset from the original hole
Bootlegs may contain unexploded explosive and must never be re-drilled; the standard remedy is a relief hole fired parallel to the original at safe offset after the misfire waiting period.
Under OSHA 1926.900 construction blasting standards, who is responsible for the safe use of explosives on a construction site?
Answer: The licensed blaster who is in charge of the blasting operations and all associated safety measures
OSHA 1926.900 places responsibility for safe explosives use on the licensed blaster-in-charge, who must oversee all aspects of storage, handling, loading, and firing.
What is a 'blast area exclusion zone' and who determines its boundaries?
Answer: The area from which all personnel and equipment must be cleared before firing, determined by the blaster-in-charge based on flyrock potential, ground conditions, and regulatory requirements
The blast area exclusion zone is site-specific and established by the blaster-in-charge to protect personnel from flyrock, airblast, and ground vibration hazards.
When transporting explosives involved in a highway accident, what is the first notification required?
Answer: Contact 911 and the National Response Center (1-800-424-8802), as required by DOT hazmat incident reporting rules under 49 CFR Part 171
DOT 49 CFR Part 171 requires immediate telephonic reporting to the National Response Center for hazardous materials transportation incidents involving release, injury, or death.
What is the proper method to dispose of deteriorated or unstable explosive materials found in a magazine?
Answer: Contact the manufacturer or a licensed explosive disposal contractor and follow ATF and applicable state guidelines for authorized destruction
Deteriorated explosives must be disposed of by a qualified contractor following ATF authorization procedures and applicable state regulations — never burn, bury, or dilute without proper authority.
Which document must a federal explosives licensee maintain on-site to account for all explosive materials received, used, and disposed of?
Answer: An ATF-compliant acquisition and disposition (A&D) record under 27 CFR 555.122 that tracks every transaction involving explosive materials
ATF 27 CFR 555.122 requires federal explosives licensees to maintain A&D records for every acquisition and disposition of explosive materials, available for ATF inspection.
