IATA Dangerous Goods Training
Certification Exam Prep Study
Guide and Practice Test Bank for
2026/2027
Which of the following statements accurately describes the recurrent training
requirements for personnel involved in packing and shipping dangerous goods?
A. Recurrent training is required only once during employment.
B. Recurrent training must occur every five years regardless of agency requirements.
C. Recurrent training frequency varies depending on regulatory agencies and job
function changes.
D. Recurrent training is required only for employees shipping Category A substances.
Correct Answer: C. Recurrent training frequency varies depending on
regulatory agencies and job function changes.
Rationale:
Recurrent training requirements for dangerous goods shipping personnel are
established by several regulatory organizations, including the Department of
Transportation (DOT), International Air Transport Association (IATA), Joint
Commission, and the College of American Pathologists (CAP). IATA requires
retraining every two years, while DOT, CAP, and Joint Commission require retraining
every three years. Additional training is also necessary whenever an employee’s job
responsibilities change or a facility’s security plan is revised. Option A is incorrect
because training is not a one-time event. Option B is inaccurate because the intervals
differ among agencies. Option D is incorrect because all personnel involved in
dangerous goods shipping activities may require training regardless of whether they
handle Category A substances.
Question 2:
Which regulatory agency publishes the Dangerous Goods Regulations (DGR) that
apply specifically to dangerous goods transported by air?
A. Occupational Safety and Health Administration (OSHA)
B. United States Postal Service (USPS)
C. International Air Transport Association (IATA)
D. Environmental Protection Agency (EPA)
Correct Answer: C. International Air Transport Association (IATA)
,2026/2027
Rationale:
The International Air Transport Association (IATA) publishes the Dangerous Goods
Regulations (DGR), which provide detailed standards for safely transporting
dangerous goods by air. These regulations are internationally recognized and are
widely used by airlines and shipping companies. OSHA primarily focuses on
workplace safety rather than transportation regulations. USPS governs mailing
regulations within postal services but does not publish the DGR. The EPA regulates
environmental protection issues rather than dangerous goods air transport standards.
Question 3:
Which of the following agencies govern the transport of dangerous goods within the
United States?
A. DOT, USPS, and ICAO
B. OSHA, CDC, and CAP
C. FDA, WHO, and EPA
D. FEMA, NIH, and DEA
Correct Answer: A. DOT, USPS, and ICAO
Rationale:
The Department of Transportation (DOT), United States Postal Service (USPS), and
International Civil Aviation Organization (ICAO) all play important roles in
regulating dangerous goods transportation. DOT oversees hazardous material
transport within the United States. USPS regulates dangerous goods sent through the
postal system. ICAO establishes international aviation standards for air transport
safety. OSHA and CAP focus more on workplace and laboratory standards rather than
transportation governance. The agencies listed in options C and D do not directly
regulate dangerous goods transportation.
Question 4:
A laboratory employee is preparing a package containing dry ice for shipment. Which
statement about dry ice packaging is correct?
A. Dry ice should be placed inside the primary specimen container.
B. Dry ice packages do not require ventilation.
C. Dry ice should only be placed between the rigid outer packaging and secondary
packaging.
D. Dry ice may be sealed tightly in an airtight container.
Correct Answer: C. Dry ice should only be placed between the rigid outer
packaging and secondary packaging.
,2026/2027
Rationale:
Dry ice sublimates into carbon dioxide gas and therefore requires vented packaging to
prevent dangerous pressure buildup. It should be positioned outside the secondary
packaging but inside the rigid outer packaging to maintain specimen temperature
safely. Placing dry ice directly in the primary container could damage the specimen or
create hazardous pressure conditions. Airtight packaging is unsafe because gas
expansion may cause rupture or explosion. Proper placement and ventilation are
essential safety requirements during transport.
Question 5:
What is the first step in the four-step process used when packing and shipping
dangerous goods?
A. Prepare package documentation
B. Determine the classification of the substance
C. Label the package
D. Determine the mode of transport
Correct Answer: D. Determine the mode of transport
Rationale:
The first step in the dangerous goods shipping process is determining the mode of
transport because transportation methods such as air, ground, or postal service have
different regulatory requirements. Once the transportation mode is identified, the
shipper can classify the substance appropriately, package it according to regulations,
and complete labeling and documentation requirements. Options A, B, and C occur
later in the shipping preparation process and cannot be completed accurately until the
transport method is known.
Question 6:
A microbiology laboratory is preparing to ship a culture of Brucella melitensis. Which
packaging components are required?
A. Plastic envelope and handwritten label only
B. Rigid outer packaging with a UN specification mark and an itemized list of
contents
C. Secondary packaging only
D. Refrigerated foam container without labeling
Correct Answer: B. Rigid outer packaging with a UN specification mark and an
itemized list of contents
Rationale:
Brucella melitensis is considered a highly infectious organism and requires compliant
, 2026/2027
triple packaging with a rigid outer container displaying a UN specification mark. An
itemized list of contents is also necessary to identify the package contents for handlers
and emergency responders. Option A lacks required safety features and
documentation. Option C omits the mandatory rigid outer packaging. Option D fails
to meet labeling and regulatory requirements necessary for dangerous goods transport.
Question 7:
When transporting a Category B infectious substance by air, which document is
required?
A. Emergency response guidebook
B. Material Safety Data Sheet (MSDS)
C. Air Waybill
D. Certificate of sterilization
Correct Answer: C. Air Waybill
Rationale:
An Air Waybill is required when shipping Category B infectious substances by air.
This document serves as the transportation contract and provides shipment tracking
and handling information. Emergency response documentation is generally associated
with Category A shipments. Material Safety Data Sheets are not the standard
documentation required for infectious substance transport. Certificates of sterilization
are unrelated to shipping documentation requirements for Category B substances.
Question 8:
If emergency response documentation is included with a shipment, the package most
likely contains which type of substance?
A. Exempt human specimen
B. Category B substance
C. Nonregulated laboratory sample
D. Category A substance
Correct Answer: D. Category A substance
Rationale:
Category A infectious substances are capable of causing permanent disability, life-
threatening disease, or fatal illness upon exposure. Because of the high risk associated
with these materials, emergency response documentation is required to assist transport
personnel and first responders in the event of an accident or spill. Exempt specimens
and Category B substances generally do not require emergency response
documentation because they present lower levels of hazard during transport.
