Question 1

Laboratory specimens are labeled with all of the following EXCEPT:

Accepted Answer

time received in the laboratory.

Answer

The Transportation of Dangerous Goods Act requires packages containing dry ice to be shipped in an unsealed container with a Miscellaneous Dangerous Goods label. Dry ice sublimes into carbon dioxide gas, and a sealed container could build up pressure and explode. The unsealed container allows the gas to escape safely, while the label identifies it as a Class 9 dangerous good.

Question 2

The Transportation of Dangerous Goods Act requires packages that contain dry ice be shipped in:

Accepted Answer

an unsealed container with a Miscellaneous Dangerous Goods label.

Answer

For a minor spill of radioactive material, the primary procedures involve containing the package, following standard decontamination, and placing it in a shielded area. Notifying local authorities (like police or fire departments) is typically reserved for major spills that pose a significant public health risk, not for minor, contained leaks that can be managed internally with established protocols.

Question 3

When a damaged package of radioactive material (classified as a minor spill) is handled, all of the following procedures should be followed EXCEPT:

Accepted Answer

notify local authorities of the leak and its extent.

Answer

The WHMIS symbol depicting a flaming circle represents 'Oxidizing Material.' This symbol indicates that the substance can cause or contribute to the combustion of other materials, meaning it 'may burn unexpectedly,' 'may react with water' (if it's a strong oxidizer), or 'may explode if exposed to shock or heat.' Environmental damage from fumes is typically associated with the 'Environment' symbol, not the oxidizing material symbol.

Question 4

Which risk is NOT associated with the following WHMIS symbol?

Accepted Answer

May cause environmental damage from fumes

Answer

This risk is not typically associated with the WHMIS symbol for explosive materials. Explosive hazards are more about the potential for sudden reactions, instability, burning, or explosions due to shock, heat, or contact with water. Environmental damage from fumes would be associated with a different hazard symbol, such as one for environmental hazards or toxic substances.

Question 5

Which hazard is matched to the hazard symbol below?

Accepted Answer

May cause permanent injury or death

Answer

The hazard symbol typically depicting a skull and crossbones, or a similar acute toxicity symbol, is universally recognized to indicate substances that can cause severe harm. This includes permanent injury or death, even from a single exposure or in small quantities. It alerts individuals to the immediate and serious health risks posed by highly poisonous materials.
