safety
Definition
Safety is the state of being safe from harm or danger. It is important to be safe in all aspects of life, but it is especially important when you are doing science experiments.
There are many things that can go wrong if you are not careful when doing science experiments. Chemicals can react dangerously, equipment can break, and people can get hurt.
That's why it is so important to follow safety procedures when you are doing science experiments. Here are some important safety procedures to follow:
- Always read and follow the instructions carefully.
- Use the correct safety equipment, such as goggles, gloves, and a lab coat.
- Be aware of your surroundings and be careful not to trip or fall.
- Do not eat or drink in the lab.
- Clean up any spills immediately.
- Ask for help if you are not sure how to do something safely.
By following these safety procedures, you can help to ensure that you have a safe and enjoyable experience when doing science experiments.

Etymology
The word "safety" comes from the Old French word "safeté", which means "security".
The first recorded use of the word "safety" in English was in the 14th century.
The word "safety" is an Old French word, and it is related to the Italian word "sicurezza" and the Spanish word "seguridad".
Question
Why is it important to consider safety before starting any activity?
AQA Science Exam Question and Answer
Question:
Explain the importance of safety protocols and precautions in scientific experiments, providing examples of potential hazards and the measures to mitigate them.
Answer:
Safety protocols and precautions are of paramount importance in scientific experiments to prevent accidents, protect researchers, and ensure reliable results. Various hazards can arise during experiments, such as chemical spills, fires, electrical shocks, or exposure to harmful substances.
For instance, when working with corrosive chemicals, proper protective gear like gloves, goggles, and lab coats should be worn to prevent skin and eye contact. Adequate ventilation systems and fume hoods can mitigate the risk of inhaling toxic fumes. When dealing with electrical equipment, grounding and insulation are essential to prevent shocks.
To further ensure safety, researchers should be familiar with emergency procedures and the location of safety equipment, such as fire extinguishers and eyewash stations. Performing experiments in designated areas and following established guidelines help minimise risks. Proper storage and disposal of chemicals also contribute to laboratory safety.
In conclusion, adhering to safety protocols and precautions is vital for the well-being of researchers and the success of scientific experiments. By recognising potential hazards and implementing appropriate measures, scientists can conduct experiments effectively while minimising the likelihood of accidents and ensuring a safe working environment.
