When using chemicals or glassware in the lab, students should use safety goggles to protect their eyes from any potential hazards. Safety goggles are designed to provide a barrier between the eyes and any harmful substances, such as chemicals or flying glass shards. They are an essential safety precaution in the lab to prevent eye injuries and ensure the well-being of the students. Steel capped shoes, a helmet, and a safety screen are not directly related to protecting the eyes and are not necessary in this context.

Students with long hair should tie it back into a ponytail to avoid accidents. By doing so, the hair is kept away from the face and eyes, reducing the risk of it obstructing vision during activities. Additionally, tying the hair back prevents it from getting caught in machinery or equipment, reducing the chances of accidents or injuries.

*##*Correct. *##*Incorrect. Horseplay and running should NEVER happen in a properly run school laboratory.

Safety goggles and laboratory coat are required for all students in the science laboratory. These safety measures are necessary to protect the students from potential hazards such as chemical splashes or flying objects. Loose and baggy clothing, loose jewellery, and scarves are not recommended as they can pose a risk of getting caught in equipment or catching fire. Therefore, safety goggles and laboratory coat are essential for ensuring the safety of students in the laboratory.

When using a fire extinguisher, it is important to aim at the base of the flame. This is because the base of the flame is where the fuel source is located. By targeting the base, you can effectively cut off the supply of fuel and extinguish the fire. Aiming at the top or center of the flame may not be as effective, as it does not directly target the source of the fire.

Chemical waste should be disposed of by putting it into a hazardous waste container. This is the correct answer because chemical waste can be harmful to the environment and human health if not properly handled and disposed of. Placing it in a hazardous waste container ensures that it is contained and can be disposed of safely by professionals who are trained in handling hazardous materials. Washing it down the sink or placing it in the rubbish bin can contaminate water sources or pose a risk to waste handlers. Hiding it under the bench is not a safe or responsible method of disposal.

In the event of a broken test tube and spilled chemical, it is important to prioritize safety and inform others about the accident. By warning your lab partners to avoid the area, you are ensuring their safety and preventing any potential harm. Additionally, going to tell the teacher about the accident is crucial as they can provide guidance on how to properly clean up the spillage and ensure that no further damage or injuries occur.

The correct answer is "raise your hand and ask your teacher for help." This is the best course of action when you are unsure how to perform an experiment. By raising your hand and asking your teacher for help, you can clarify any confusion or uncertainties you may have, ensuring that you have a clear understanding of the experiment instructions and increasing your chances of success.

*##*Correct. These are the minimum requirements for every experiment.*##*Backpacks and schoolbags are a hazard in the laboratory.
Purses really are not a requirement for working in the laboratory.

A fire blanket would be the best option to use if a student's jumper catches fire. Fire blankets are specifically designed to smother and extinguish small fires by cutting off the oxygen supply. They are made of fire-resistant materials and can be wrapped around a person to quickly smother the flames and prevent further injury. Fire extinguishers are typically used for larger fires, safety goggles are used to protect the eyes, and fire alarms are used to alert people of a fire but do not directly extinguish the flames.

*##*Correct answer.*##*You have not got all of them correct

When heating a test tube over a flame, it is important to hold the test tube away from other people to ensure their safety. This is because heating a test tube can cause it to break or explode, and holding it away from others reduces the risk of anyone getting injured by shattered glass or hot substances.

*##*Correct. This is the right method.*##*Incorrect. If a fire breaks out, pass the extinguisher to a more competant person.

A student should smell a chemical by wafting the fumes towards their nose by using their hand because this method allows for a controlled and diluted exposure to the scent. By gently waving the hand over the container, the student can avoid inhaling a concentrated amount of the chemical, which could be harmful. This technique helps to prevent any potential adverse effects and ensures the student can safely assess the odor of the chemical.
