Assessing Risks and Hazards in Chemistry

Why was PPE selected for the actors in the video?

• To make them look professional

• Based on a risk assessment of the chemicals used

• Because it was a requirement for filming

• To match the color of their lab coats

What does RAMP stand for?

• Respond, Assess, Manage, Prevent

• Recognize, Avoid, Mitigate, Plan

• React, Analyze, Manage, Protect

• Recognize, Assess, Minimize, Prepare

What is the difference between a hazard and a risk?

• A hazard is always visible, while risk is invisible

• A hazard is a potential source of harm, while risk is the likelihood of that harm occurring

• A hazard is a minor issue, while risk is a major issue

• A hazard is a chemical, while risk is a physical object

In the risk matrix, what are the two axes used to represent?

• Chemical and Equipment

• Exposure and Protection

• Hazard and Risk

• Severity and Likelihood

What is an example of minimizing risk when pouring a strong acid into a burette?

• Pouring quickly

• Using a funnel and lowering the burette

• Using a larger container

• Not wearing any protective gear

What additional hazard is present when diluting concentrated sulfuric acid?

• It changes color

• It produces a toxic gas

• It creates an exothermic reaction that generates heat

• It becomes less corrosive

Why is assessing the severity of hazards challenging?

• Because it involves quantitative measurements and judgment calls

• Because hazards are always changing

• Because it requires no experience

• Because it is a simple process

What does LD50 refer to?

• The limit of detection for a chemical

• The legal dose for laboratory use

• The level of dilution for a solution

• The lethal dose for 50% of a population

Why might different people judge the same level of risk differently?

• Because they use different chemicals

• Because they work in different labs

• Because they follow different protocols

• Because they have different levels of experience and tolerance for risk

Where can you find more information about the RAMP protocol?

• In the video description or at acs.org/safetyvideos

• In your chemistry textbook

• By asking your lab partner

• In the lab safety manual
