Safety for the Classroom
Today we are going to cover the safety precautions of a classroom

2. 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.

3. 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

4. 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

5. 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

6. 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

7. 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.

8. 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.

9. 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

10. 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.
