#1
What does the acronym 'MSDS' stand for in the context of explosive safety?
Material Safety Data Sheet
ExplanationProvides comprehensive information about the hazardous materials, including their properties, health effects, and safety precautions.
#2
Which of the following is NOT a primary hazard associated with explosives?
Electromagnetic interference
ExplanationRefers to disruption caused by electromagnetic radiation, not typically associated with explosives.
#3
What is the primary purpose of a blast wall in explosive safety management?
To contain an explosion
ExplanationConstructs a barrier to confine and redirect blast effects away from vulnerable areas.
#4
Which of the following is NOT a typical safety precaution when handling explosives?
Smoking near explosive storage areas
ExplanationSmoking near explosive storage areas poses a significant risk of ignition and should be strictly prohibited as a safety precaution.
#5
What is the primary function of a detonator in an explosive system?
To initiate the explosion
ExplanationA device containing a small amount of sensitive explosive used to trigger the main charge.
#6
In explosive safety, what does 'MMPR' commonly refer to?
Minimum Safe Separation Distance
ExplanationThe closest safe distance to keep personnel or structures from an explosion to prevent injury or damage.
#7
What is the primary purpose of a blast shelter in explosive safety management?
To reduce the effects of an explosion
ExplanationProvides protection to personnel and structures by minimizing exposure to blast effects.
#8
What does the term 'UN classification' refer to in the context of explosives?
United Nations Classification
ExplanationSystem categorizing explosives based on their characteristics and associated hazards.
#9
Which of the following is NOT a factor affecting the sensitivity of an explosive?
Color
ExplanationColor has no bearing on an explosive's sensitivity; factors include chemical composition, particle size, and temperature.
#10
What is the primary function of a detonation cord in explosive operations?
To initiate detonation
ExplanationA flexible cord containing explosive material used to transmit detonation signals efficiently.
#11
In explosive safety, what is the purpose of a 'buffer zone'?
To absorb shock waves
ExplanationArea designed to absorb or dissipate the energy of an explosion, reducing its impact on surrounding structures.
#12
What is the typical function of a detonator in an explosive system?
To initiate the explosion
ExplanationInitiates the chemical reaction in the explosive material, leading to detonation.
#13
What does the term 'REACH' signify in relation to explosive safety?
Regulation for the Evaluation, Authorization, and Restriction of Chemicals
ExplanationEuropean Union regulation governing the production and use of chemical substances.
#14
What is the primary purpose of conducting a Hazard and Operability Study (HAZOP) in explosive safety management?
To identify potential hazards and operability issues
ExplanationSystematic examination of a process or operation to identify potential hazards and operational problems.
#15
What does the term 'EBW' stand for in explosive technology?
Exploding Bridge Wire
ExplanationInitiates explosive reactions by rapidly heating a wire until it explodes.
#16
What is the purpose of a shock tube in explosive testing?
To initiate detonation
ExplanationA tube filled with a low-energy explosive used to transmit a shock wave to initiate detonation in a primary explosive.
#17
What is the primary purpose of a detonation wave in explosive reactions?
To propagate the explosion
ExplanationThe shock wave produced by detonation that propagates through the explosive material, causing rapid expansion and release of energy.
