The video tutorial introduces health and safety in laboratory settings, focusing on the language and processes involved. It covers hazardous substances, their symbols, and the difference between hazard and risk. The importance of risk assessments and control measures is emphasized, along with the use of personal protective equipment (PPE) based on these assessments. The tutorial concludes with practical applications of safety protocols in classroom experiments.

Which of the following symbols indicates a substance that is hazardous to the environment?

• Dead fish and tree

• Corrosive

• Flammable

• Toxic

What is the primary difference between a hazard and a risk?

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

• A hazard is always visible, while a risk is not.

• A risk is always more dangerous than a hazard.

• A hazard is a type of risk.

What is the purpose of a risk assessment in the lab?

• To identify potential hazards and minimize the likelihood of harm.

• To eliminate all hazards.

• To increase the number of experiments conducted.

• To ensure all experiments are successful.

Which of the following is NOT a control measure mentioned in the video?

• Appropriately handling substances

• Increasing the number of experiments

• Implementing aseptic techniques

• Using personal protective equipment (PPE)

When might a healthcare worker need to use a full face mask and filtration unit?

• When handling corrosive substances

• When dealing with potential airborne particles

• When within a meter of a suspected COVID patient

• When working with chemicals that may splash

What should be done if a new hazard is identified during an experiment?

• Stop all experiments immediately

• Update the risk assessment and adjust control measures

• Ignore it and continue the experiment

• Report it to a colleague

What is the first step in the risk assessment protocol used in schools?

• Evaluate the risks

• Identify any hazards

• Decide on precautions

• Record findings

Why is it important to constantly review and update risk assessments?

• To minimize the risk of harm from newly identified hazards

• To ensure experiments are more exciting

• To increase the number of experiments conducted

• To reduce the cost of experiments

What is the main focus of the health and safety subcarrier in the lab?

• Increasing the number of experiments conducted

• Reducing the cost of lab equipment

• Learning about different types of experiments

• Understanding the language of health and safety

What will the next subcarrier focus on after health and safety?

• Genetic engineering

• Solid and gas handling

• Microscopy techniques

• Liquids and solutions
