Lab safety rules for middle school is all about prevention and control of laboratory hazards. Middle school represents a school for children from about 9 to 13 years old (in the UK); (in the US and Canada) a junior high school.
High voltages, high and low pressures and temperatures, corrosives and toxic chemicals and chemical vapours, radiation, fire, explosions, and biohazards, including infective organisms and their toxins, are examples of risk factors. The prevention of laboratory accidents requires great care and constant vigilance.
Safety training and enforcement of laboratory safety policies, safety reviews of experimental designs, the use of personal protective equipment, and following lab safety rules for middle school are all ways to prevent accidents in laboratories.
There are different hazards in the laboratory which the middle school children should be protected from even when they are learning about it or experimenting in the lab.
Such are chemical hazards which workers in clinical, industrial, and academic laboratories face physical and/or health risks from hazardous chemicals. Agents that act on the blood system or damage the lungs, skin, eyes, or mucous membranes are examples of laboratory chemicals, as are agents that cause cancer (carcinogens), toxins (such as those affecting the liver, kidney, and nervous system), irritants, corrosives, and sensitizers; biological hazards – Biohazard symbol (black and yellow), Biological agents and biological toxins. These dangers can be found in the laboratory’s culture specimens, blood and other body fluids, body tissue and cadavers, laboratory animals, and other workers.
These are biological agents and toxins that are regulated by the federal government and have the potential to severely harm public health and safety, animal or plant health, or animal or plant products and the middle school children are not left out. Examples include viruses, bacteria, fungi, and prions. Bacillus anthracis, a spore-forming bacterium, is responsible for the acute infectious disease known as anthrax; physical hazards where laboratory workers and the children may also be exposed to a variety of physical hazards in addition to biological and chemical agents.
The following are some typical physical dangers that they might encounter: hazards related to ergonomics, non-ionizing radiation, ionizing radiation, and noise; ergonomic risks which may occur during routine laboratory procedures like pipetting, working at microscopes, operating microtomes, using cell counters, and keyboarding at computer workstations. They are at risk of repetitive motion injuries.
Lab Safety Rules For Middle School
Having looked at all these, let’s look at way to prevent injuries and accidents in science labs:
- Unless directed otherwise, children should not be allowed to touch any chemicals or laboratory equipment. No procedures or experiments should be attempted without authorization.
- Students should never work in the science lab without their teachers present and they must comply with their instructor’s instructions.
- During the science experiment, students must follow all written and verbal instructions. If they do not understand something, they have to ask questions first.
- When working in a science laboratory, it is critical to keep an eye out and exercise caution. It should be strictly forbidden to eat, drink, engage in pranks, use a mobile phone, or listen to music. You can not eat or drink anywhere in the lab!
- Carefully read the label on any chemicals before using them. Keep the chemical in the test tube away from your face, mouth, and body when conducting the experiment or mixing the chemicals.
- The original bottle of chemicals should never be used again. They must be disposed of in accordance with the directions provided by the science teacher or lab assistant.
- In the science laboratory, students must wear safety goggles, a lab coat, and shoes. In school science labs, loose clothing, sandals, and open hair should be strictly prohibited. If you do not want your chin-length or longer hair to catch fire, tie it back. Dress sensibly, including your footwear. In order to prevent them from getting caught in a flame or chemicals, loose clothing should be secured.
- Before using glassware, examine it. Beakers and test tubes that are chipped or cracked should not be used.
- When heating substances or dissecting, for example, put on safety goggles to shield your eyes. It takes time to cool down hot equipment. Pick them up with tongs or heat-resistant gloves after allowing them time to cool down and never point a heated test tube at yourself or another student. When heating a test tube, never look into it.
- Do not be alarmed in the event of an accident. Immediately inform your instructor and lab assistants for assistance.
- By placing additional items (books, bags, etc.) under the work tables or on the shelves, you can keep pathways clear. Check to see that these items cannot be stepped on if they are beneath the tables.
- It is strictly forbidden to “horse play” or fool around in the laboratory. Students who break this safety rule will not be allowed to take part in any more labs and could be suspended. Work quietly and read the assigned experiment beforehand to understand what you are doing. Pay close attention to any warnings in the lab exercises.
- You must obtain permission from the instructor before leaving your designated laboratory station and before leaving the laboratory, clean and tidy your workstation.
In addition to these, students should be tested on their knowledge of laboratory safety. You must ensure that students fully comprehend the rules and their application. These are some steps to ensure that they understand the rules.
