3.1 Planning and Risk Assessment

• The aim of an investigation is to clearly define its purpose and objectives.


  True
• A well-structured lab plan includes an aim, materials and equipment list, a procedure, safety precautions, and data
• A hazard is an inherent property of a substance or situation.


  True
• Having a well-structured lab plan is essential for ensuring a successful and safe experiment
• A hazard is a potential source of harm or danger
• Match the term with its description:

  Hazard ↔️ Potential source of harm

  Risk ↔️ Likelihood and severity of harm
• Match the safety symbol with its meaning:

  Corrosive ↔️ Substances that can damage other materials

  Flammable ↔️ Substances that can easily ignite
• Risk is a combination of the probability of a hazard occurring and its consequences.


  True
• Match the hazard with its associated risk:

  Flammable chemicals ↔️ High chance of fire

  Sharp objects ↔️ Potential for deep cuts
• Arrange the key elements of a comprehensive risk management plan.

  1️⃣ Identify potential hazards

  2️⃣ Assess the risks

  3️⃣ Implement mitigation measures

  4️⃣ Establish emergency protocols
• The planning stage in scientific investigations involves identifying the aim, selecting appropriate methods, and considering potential risks
• Arrange the components of a well-structured lab plan in the correct order.

  1️⃣ Aim

  2️⃣ Materials and Equipment

  3️⃣ Procedure

  4️⃣ Safety Precautions

  5️⃣ Data Recording
• Having a well-structured lab plan is optional for ensuring a successful and safe experiment.

  False
• Selecting appropriate methods involves choosing the most suitable procedures, equipment, and techniques
• The aim in a lab plan should clearly state what the investigation intends to discover.

  True
• Risk combines the probability of a hazard occurring with the severity of its consequences
• Arrange the components of a well-structured lab plan in the correct order.

  5️⃣ Data Recording
• What is risk in the context of laboratory safety?

  Likelihood and severity of harm
• What do safety symbols indicate in a laboratory environment?

  Potential hazards
• What does the biohazard safety symbol indicate?

  Infectious biological materials
• A hazard in a chemical experiment is a potential source of harm or danger
• Risk management strategies include identifying hazards, assessing risks, and implementing mitigation measures.


  True
• What is the purpose of risk mitigation in scientific experiments?

  Reduce identified risks
• What is the aim of a well-structured lab plan?

  Ensure a successful and safe experiment
• What is the purpose of the "Aim" component in a well-structured lab plan?

  To state the investigation's purpose
• Match the components of a lab plan with their descriptions:

  Aim ↔️ The purpose of the experiment

  Materials and Equipment ↔️ A comprehensive list of items

  Procedure ↔️ A step-by-step guide

  Safety Precautions ↔️ Measures to mitigate risks
• Risk combines the probability of a hazard occurring with the severity
• The Biohazard symbol indicates the presence of infectious biological materials
• Risk is solely determined by the probability of a hazard occurring.

  False
• What does the "Corrosive" safety symbol indicate?

  Substances that damage materials
• Risk is a combination of the probability of a hazard occurring and its potential consequences
• What are the three key elements of a comprehensive risk management strategy?

  Risk Assessment, Mitigation, Emergency Protocols
• Identifying hydrochloric acid as a corrosive hazard is an example of risk
• Order the steps in documenting safety procedures:

  1️⃣ Risk Assessment

  2️⃣ Risk Mitigation

  3️⃣ Emergency Protocols
• Order the steps in the planning stage of scientific investigations:

  1️⃣ Identifying the Aim

  2️⃣ Selecting Appropriate Methods

  3️⃣ Considering Potential Risks and Safety Measures
• The planning stage in scientific investigations involves three key steps
• The aim of an experiment should clearly state what you intend to investigate.


  True
• A hazard is the likelihood and severity of harm from a potential danger.

  False
• Toxic substances can cause injury, illness, or death
• Flammable chemicals are examples of hazards in a lab.
