5- Self test questions Flashcards
What is the goal of control measures?
To break the chain of infection.
Which type of controls are methods of isolating, removing, or transmitting the transmission of
biological hazards?
Engineering controls.
What is the first step before you can make chemical hazard control recommendations?
Determine what it is about a substance or chemical that makes it hazardous.
Why are gases and vapors usually grouped together?
They behave similarly. For example, both will expand and contract with changes in temperature and
pressure. Both spread out (diffuse) rapidly to fill a room, enabling quicker exposure to the chemical. Both forms can enter the body quite easily and cause rapid toxic action(s).
Why is it important to have a working knowledge of a chemical’s physical properties,
nomenclature, and exposure effects?
To ensure a proper assessment of a solvent exposure.
Why is paint itself not a chemical you can evaluate?
Paint is a composite mixture; the component chemicals must be evaluated to determine both the individual and collective hazards present.
If an SDS is not provided with the first shipment of a hazardous chemical, how is one obtained?
The workplace supervisor must request it from the manufacturer or supplier.
When must carcinogenic chemicals be listed on an SDS?
If the concentration of the chemical is ≥ 1%.
What part of an SDS provides information on how to handle an accidental chemical spill?
Accidental release measures.
Where on the SDS would you look to determine if there are any PPE requirements when working
with a specific chemical?
Exposure controls section.
Why did OSHA develop/publish substance specific standards?
To provide additional measures to protect workers that use chemicals where adherence to the PEL is not
enough.
When must the requirements contained in a substance specific standard be implemented?
If air sampling results indicate exposure levels greater than the PEL.
On what two factors does the degree of risk of exposure to a given substance depend?
The magnitude and duration of exposure.
When do you begin identifying chemical threats?
When you define the processes occurring in and around the work environment or area of concern, along with an understanding of the materials and equipment being used in the processes.
What is the primary source for locating chemical ingredient information?
SDS.
