Standards of Practice Flashcards

Laboratory specimens are labeled with all of the following EXCEPT:

Answer: time received in the laboratory.

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.

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

Answer: an unsealed container with a Miscellaneous Dangerous Goods label.

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.

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

Answer: notify local authorities of the leak and its extent.

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.

Which risk is NOT associated with the following WHMIS symbol?

Answer: May cause environmental damage from fumes

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.

Which hazard is matched to the hazard symbol below?

Answer: May cause permanent injury or death

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.

Where there is a risk of aerosol production, Level 2 containment requires a minimum of:

Answer: Level 1 biosafety cabinet

For Level 2 containment, when there is a risk of aerosol production, a Class I or Class II biosafety cabinet (BSC) is required. These cabinets, often referred to as Level 1 biosafety cabinets in some contexts, provide essential personnel and environmental protection. They achieve this by filtering exhaust air and maintaining an inward airflow, effectively containing aerosols and preventing their release into the laboratory environment.

According to the Clinical and Laboratory Standards Institute (CLSI) which type of water should be used for routine laboratory assays?

Answer: Clinical Laboratory Reagent Water (CLRW)

According to the Clinical and Laboratory Standards Institute (CLSI), Clinical Laboratory Reagent Water (CLRW) is the standard for routine laboratory assays. CLRW, formerly known as Type I water, has stringent specifications for microbial count, resistivity, and organic contaminants. This ensures it is free from impurities that could interfere with test results, maintaining the accuracy and reliability of diagnostic tests.
