Safety for the Classroom Introduction to Drafting and Design Safety for the Classroom Today we are going to cover the safety precautions of a classroom

Safety Terms Safety Accident Hazard First Aid Fire Triangle Classes of Fires Some safety terms that we are going to cover are: Safety, accident, hazard, first aid, fire triangle, and classes of fires.

Let’s Define… Safety Accident The state or condition of being safe or free from danger, risk and injury Accident A sudden occurrence or unintentional event that causes injury or property damage Safety The state or condition of being safe or free from danger, risk and injury Accident A sudden occurrence or unintentional even that causes injury or property damage

Let’s Define… Hazard First Aid A potential source of danger The immediate temporary care given to the victim of a sudden accident or illness until proper medical attention can be given Hazard A potential source of danger First Aid The immediate temporary care given to the victim of a sudden accident or illness until proper medical attention can be given

Fire Triangle There are three main components to fire: Oxygen Heat Fuel Take away any of these three elements and you will not have a fire Fire Triangle: There are three main components of fire: Oxygen is needed to sustain the combustion Heat is needed to raise the material to its needed ignition temperature Fuel is needed to start the combustion Then you need the chemical reaction that is fire to start the whole process

Classes of Fire Five classes of fires Class A Occur in ordinary combustible materials Class B Occur in flammable liquids Class C Occur in or near electrical equipment Class D Occur with combustible metals Class K Occur with cooking oils and fats Class A and Class C are most likely to occur in the drafting lab There are five classes of fires that can occur Class A Occur in ordinary combustible materials Ordinary materials include wood, paper, or trash Class B Occur in flammable liquids such as oil and gas Class C Occur in or near electrical equipment Class D Occur with combustible metals such as Magnesium and Titanium These fires can’t be extinguished with water Class K Occur with cooking oils and fats Class A and Class C are most likely to occur in the drafting lab

Classes of Fire Extinguisher Now that we have talked about the types of fires, we need to know how to extinguish them. There are four types of extinguishers: water, foam, dry powder and carbon dioxide. As you can see in this chart Class A fires use water, foam and dry powder extinguishers Class B fires use foam, dry powder and CO2 extinguishers Class C fires can only be extinguished using dry powder extinguishers Class D fires can be extinguished with dry powder and CO2 Class K fires use foam and CO2 extinguishers Extinguishers essentially remove one of the parts of the fire triangle and thus extinguishing the fire.

Who’s responsible? School Teacher Students Adequate facilities Large classrooms Emergency plan Teacher Provide an organized, progressive program Adequate instruction Planned cleanup program Students Conduct themselves in a safe manner Responsible for their own area Responsible for the care of the equipment So who is responsible for different aspects of keeping the school a safe place during class hours? Let’s begin with the school staff such as the principal The principal and school administration is responsible for providing adequate facilities such as large enough classrooms to accommodate the large number of students. Students should not be crowded. The classrooms should also have adequate lighting and temperature to keep the students safe. They are also responsible for providing emergency plans for the students and instructors to follow in case of a serious emergency. Next are the teachers The teachers are responsible for providing a well organized and progressive instructional program that keeps students occupied. If students are occupied then they aren’t able to horseplay and potentially injure themselves. The teacher is also supposed to inform the students of the correct way to handle all equipment that is used within the classroom. With the proper education on how to use the equipment, students are less likely to misuse the equipment and potentially endanger themselves. Finally the teachers need to ensure that the students are aware of the cleanup program. The cleanup program allows for the classroom to remain clean and free from potential hazards to the students. Finally the students have responsibilities in keeping the classroom safe as well They need to conduct themselves in a safe and mature manner. There is a time and place for horseplay and goofing around but the classroom is not the place to do that. Students need to be responsible for their work space including their desk and the surrounding area. Students need to keep their desk neat and clean. They need to organize the equipment in a manner that the equipment won’t be damaged or become a harm to other students. To decrease the potential hazards, students need to keep their desks in line with each other, pick up any and all trash that surrounds their workspace and return the tools to their proper location. If all parties work together in their responsibilities then the classroom will be a safe place for students to learn and draw.

What to do in an emergency? In case of an accident in the classroom: Students should notify the teacher Send someone for the nurse Administer first aid to the victim and remove them from danger If needed call for paramedics What do we do if there is an emergency that occurs in the classroom? In case of an accident in the classroom: Students should notify the teacher Send someone for the nurse Administer first aid to the victim and remove them from danger If needed call for paramedic

Rules for Personal Safety Keep the chairs and stools on all four legs No running or horseplay Use equipment with permission only Conduct yourself in a safe manner Use the tools and equipment for their intended purpose only Report all accidents to the teacher Only lift heavy objects with proper supervision Use paper cutter with caution Some rules to go by when practicing safety in the classroom: Keep the chairs and stools on all four legs No running or horseplay Use equipment with permission only Conduct yourself in a safe manner Use the tools and equipment for their intended purpose only Report all accidents to the teacher Only lift heavy objects with proper supervision Use paper cutter with caution Your teacher may have additional classroom rules for personal safety that need to be followed for the betterment of a proper learning environment for you and your classmates.
