Overview
This lecture introduces core principles of laboratory safety using the RAMP framework, emphasizing the importance of risk management and personal responsibility in the chemistry lab.
Principles of Lab Safety
- Lab safety principles build on high school rules and adapt to varying risk levels in college labs.
- Risk management guides safe lab behavior and decision-making.
The RAMP Framework
- RAMP stands for Recognize hazards, Assess the risk, Minimize the risk, and Prepare for emergencies.
Recognize Hazards
- Hazards are anything that can harm you, such as chemicals, equipment, or procedures.
- Example: Sulfuric acid is hazardous to skin; heating flammable chemicals also introduces risk.
Assess the Risk
- Risk is the chance of being harmed by a hazard, based on severity and likelihood of exposure.
- Risk can be calculated: Risk = Severity of hazard × Likelihood of exposure.
- Example: More acid on your skin or inhalation of vapors increases risk.
Minimize the Risk
- Use chemical hoods to avoid inhaling vapors and wear eye protection and gloves to prevent injury.
- Substitute less hazardous chemicals or use lower concentrations and smaller amounts when possible.
- Lower procedure temperatures to reduce burn risk.
Prepare for Emergencies
- Be ready to handle fires, spills, and other incidents.
- Always think ahead about potential problems and know response procedures.
Safety Culture and Attitude
- A positive safety culture in the lab depends on personal responsibility and ethics.
- Value and promote safety, work safely, and avoid risky behavior.
- Continually develop safety knowledge, skills, and the right attitude.
Key Terms & Definitions
- Hazard — Any source that can cause harm (chemical, equipment, or procedure).
- Risk — The chance of being harmed by a hazard, calculated by severity and likelihood of exposure.
- RAMP — An acronym for Recognize hazards, Assess the risk, Minimize the risk, Prepare for emergencies.
Action Items / Next Steps
- Watch the additional videos in this safety series for deeper understanding.
- Review your lab’s emergency procedures and safety protocols.
- Reflect on how you can contribute to a culture of safety in your lab.
