From Chemical Safety Rules to Risk Management | ACS College Safety Video #1

Main ideas and lessons

• Lab safety goes beyond memorizing rules: While college chemistry often revisits high-school safety rules, the video emphasizes extending them using risk management principles that apply to new situations.
• Personal Protective Equipment (PPE) is chosen based on risk: In the video’s staged scenes, PPE is selected by considering:
  • The chemicals used
  • The conditions simulated
  • If the presenter is not wearing PPE in the lab, all chemicals are removed to eliminate chemical hazards.
• Safety culture matters: Students should actively contribute to a positive institutional safety culture through attitude and ethics, not just compliance.

Risk management methodology: RAMP

The video presents a step-by-step approach using the acronym RAMP.

R — Recognize hazards

A hazard is something that can harm you.

Hazards in a chemistry lab can come from:

• Chemicals
• Equipment
• Procedures

Examples:

• Sulfuric acid
  • Useful because it reacts with many chemicals
  • Hazard because it can react with skin, causing chemical burns
  • In some cases, the procedure is hazardous—e.g., heating a solution
• Heating a solution
  • The source of heat creates the hazard
  • Risk is especially high if a flammable reagent is involved

A — Assess the risk

Risk is the chance of being harmed by a hazard.

Risk depends on two factors:

• Severity of the hazard
• Likelihood of exposure

The video’s relationship:

• Risk = severity of hazard × likelihood of exposure

Examples:

• High-concentration nitric acid
  • Very hazardous due to being a strong acid and an oxidizer
  • Risk may be lower if exposure is minimal (e.g., only one drop that can be washed off)
  • Risk increases sharply if exposure is larger (e.g., 50 mL spilled on a leg)
• Ethyl ether
  • Unsafe vapor to breathe
  • Open lab use → significant inhalation risk
  • Chemical hood use → much safer because inhalation likelihood is reduced

M — Minimize the risk

This step produces many “familiar” lab safety rules.

Examples of common risk-minimizing controls:

• Use a chemical hood to avoid breathing hazardous gases/vapors
• Wear eye protection to prevent corrosives damaging eyes
• Wear gloves and/or a lab coat when procedures may expose skin to hazards

Additional questions/control ideas to reduce exposure:

• Can you use a less hazardous chemical instead?
• Can you use lower concentrations?
• Can you run the reaction with smaller quantities?
• Can you reduce temperature to lower burn risk?

Key principle:

• All risk can’t be eliminated, but it should always be reduced to acceptable levels.

P — Prepare for emergencies

If something goes wrong, you should already be ready.

Examples of preparation the video prompts:

• Knowing how to handle a fire
• Knowing how to respond to a spill

Core lesson:

• Think deliberately about what could go wrong and be ready to respond.

Safety culture: ethics and responsibility

• Safety learning depends on institutional culture.
• Students should support a positive safety culture by:
  • Valuing safety
  • Working safely
  • Not engaging in risky behavior
  • Promoting safety
  • Accepting responsibility for safety

What the series will cover next (as signposted)

The video emphasizes there is more to safety than rules:

• What hazards experiments present
• How to learn about hazards
• How to decide which hazards create real risk
• How serious risk is
