Which Biosafety Level (BSL) is required for work with agents that may cause serious or potentially lethal disease for which vaccine or therapy may be available?
Answer: BSL-3
BSL-3 containment is required for agents that cause serious or potentially lethal disease via respiratory transmission where treatment or vaccines may exist.
An improper chemical storage practice that can lead to a violent reaction is storing:
Answer: Concentrated nitric acid next to acetone
Concentrated nitric acid (an oxidizer) stored next to acetone (a flammable organic solvent) is an incompatible combination that can result in fire or explosion.
Which OSHA standard specifically regulates occupational exposure to hazardous chemicals in laboratories (non-production settings)?
Answer: 29 CFR 1910.1450
29 CFR 1910.1450, the Occupational Exposure to Hazardous Chemicals in Laboratories standard, applies specifically to laboratory use of chemicals and requires a Chemical Hygiene Plan.
A laboratory is required to conduct a formal incident investigation after a near-miss primarily to:
Answer: Identify root causes and prevent a future, potentially more serious event
Near-miss investigations identify root causes and systemic failures before an actual injury or loss event occurs, making them critical for proactive safety management.
When a chemical is listed as a 'carcinogen' under the OSHA Laboratory Standard, what specific additional requirement applies to work with that substance?
Answer: A designated area must be established for its use
The OSHA Laboratory Standard requires that work with select carcinogens, reproductive toxins, and acutely toxic substances occur in a designated area with appropriate controls.
Which personal protective equipment is NOT adequate protection when handling a highly concentrated solution of hydrofluoric acid (HF)?
Answer: Nitrile gloves (4 mil, single layer)
Thin single-layer nitrile gloves provide inadequate protection against HF; thick, HF-rated neoprene or butyl rubber gloves or multi-layer glove systems are required.
The 'Right-to-Know' principle for laboratory workers means that employees are entitled to information about:
Answer: The identities, hazards, and safe handling procedures for chemicals they may be exposed to
Right-to-Know laws (codified in OSHA HazCom) give workers the right to be informed about chemical identities, hazards, and safe handling measures for substances they may encounter.
