Overview
This lecture explains how to assess and manage risks in the laboratory using the RAMP protocol, emphasizing the differences between hazards and risks and how to minimize them.
Hazards and Risks in the Lab
- Hazards are sources of potential harm, such as chemicals that may be corrosive, toxic, reactive, or flammable.
- The amount of a chemical does not change its hazard; intrinsic properties define the hazard.
- Risk is determined by both the severity of the hazard and the likelihood of exposure or occurrence.
- The risk equation: Risk = Severity x Likelihood.
- Risk is visualized using a matrix with axes for severity (low, medium, high) and likelihood (low, medium, high).
The RAMP Protocol
- RAMP stands for Recognize hazards, Assess risks, Minimize risks, and Prepare for emergencies.
- Recognizing hazards is the first step; this lecture focuses on assessing and minimizing risks.
Assessing and Minimizing Risks
- Evaluating risk can be subjective and depends on experience and technique.
- Example 1: Pouring strong acid into a burette is medium/high severity; using a funnel or lowering the burette reduces risk.
- Example 2: Diluting concentrated sulfuric acid has high severity; adding acid to water slowly and wearing protection reduces risk.
- Risk can be reduced by using the right equipment, proper technique, and wearing appropriate personal protective equipment (PPE).
Challenges in Risk Assessment
- Assessing hazard severity may require understanding terms like LD50, permissible exposure limit, or flash point.
- Likelihood of exposure changes with the user's experience level in the lab.
- Acceptable risk levels can vary among individuals and institutions.
Importance for Students
- Most undergraduate lab procedures are already low risk by design.
- Understanding and applying risk assessment becomes more important in advanced courses and professional lab work.
Key Terms & Definitions
- Hazard — A source of potential harm with intrinsic dangerous properties.
- Risk — The chance of harm, calculated as the product of hazard severity and exposure likelihood.
- Risk Matrix — A tool to visually assess risk based on severity and likelihood.
- RAMP — Safety protocol: Recognize, Assess, Minimize, and Prepare for emergencies.
- PPE (Personal Protective Equipment) — Gear worn to minimize exposure to hazards.
Action Items / Next Steps
- Watch the additional RAMP protocol videos for deeper safety understanding.
- Review definitions of hazard measurement terms like LD50 and flash point.
- Practice applying risk assessment steps during future lab sessions.
