Safety in the classroom

1. Safety in the classroom

2. Here at Cane Ridge certain incidents can occur that can require emergency procedures.

3. Can you think of any? • Fire • Tornado • Medical Emergency • Disaster (per principal) • Intruder • Bomb threat • Accidents (injuries)

4. FIRE • Four elements are needed to create a fire: fuel, oxygen, heat, and a chemical reaction. • Fuel is any combustible material, solid, liquid or gas. Most solids or liquids become a vapor or gas before they burn. Oxygen exists in the air we breathe, which contains about 21% oxygen. A fire only needs an atmosphere of 16% oxygen. • Heat is the energy necessary to increase the temperature of the fuel to a point where sufficient vapors are given off for ignition to occur. • A chemical reaction with fuel, oxygen, and heat must be present in the correct levels in order for fire to occur. • By removing any one of these four elements, a fire cannot exist, or it will be extinguished if it is already burning

5. Causes of Fire • Can be frayed cords on electrical devices • When a power cord is damaged, the appliance should be removed from service and the cord replaced as soon aspossibleto reduce the risk of electrical shock, electrocution or fire.

6. FIRE Knowing the type of fuel helps determine what kind of fire extinguisher to use and how to use it. There are five common classes of fires: Fire Class Fuel • A Ordinary combustibles such as paper, cloth, wood, rubber, and many plastics • B Flammable liquids (e.g., oils, gasoline) and combustible liquids (e.g., charcoal lighter fluid, kerosene) • C Energized electrical equipment (e.g., wiring, motors) – when the electricity is turned off, the fire becomes a Class A fire • D Combustible metals (e.g., aluminum, magnesium, titanium) • K Vegetable oils, animal oils, or fats in cooking appliances

7. FIRE • Never use water on a fire unless you know what is burning. Water conducts electricity, causing the problem to spread and cause more shorting in the equipment. Water will also move burning oil, gas, and other petroleum products into new areas to ignite.

8. Extinguishing a FIRE • • STEP 1: PULL. Pull the pin. This will also break the tamper seal. • • STEP 2: AIM. Aim low, pointing the extinguisher nozzle (or its horn or hose) at the base of the fire. Note: Do not touch the plastic discharge horn on CO2 extinguishers; it could get very cold and may damage skin. • • STEP 3: SQUEEZE. Squeeze the handle to release the extinguishing agent. • • STEP 4: SWEEP. Sweep from side to side at the base of the fire until it appears to be out. Watch the area. If the fire re-ignites, repeat steps 2 through 4.

9. Extinguishing a FIRE When using a fire extinguisher: • Always stand with an exit at your back. • Stand several feet away from the fire, moving closer once the fire starts to diminish. • Use a slow, sweeping motion and aim the fire extinguisher nozzle at the base of the fire. • If possible, use a "buddy system" to have someone back you up or to call for help if something goes wrong.

10. RACE • R = RESCUE anyone in immediate danger from the fire, if it does not endanger your life • A = ALARM: sound the alarm by calling “2600” (on-campus locations only) and activating a pull station alarm box • C = CONFINE the fire by closing all doors and windows • E = EXTINGUISH the fire with a fire extinguisher, or EVACUATE the area if the fire is too large for a fire extinguisher.

11. Medical Emergency • Try not to leave the person unattended. • Tell the closest adult • Call for the school nurse

12. How can I be prepared for a Disaster? • Know the floor plan of your facility • Know where the nearest exit is located • Know where the alarms and fire extinguishers are located

13. Occupational Safety and Health Administration Est. 1970 under Department of Labor

14. OSHA Establishes standards for safety in the workplace Also enforces those standards

15. Who is responsible? • The Employer • Furnish a place of employment free from hazards • Comply with OHSA standards • Keep Records

16. Responsibility cont’ • Employee • Must comply with standards, rules, and regulations • No person can be fired or treated with discrimination for filing a complaint

17. Citations • If a violation of a standard is made • Is written and on file • Employer must comply within a reasonable amount of time • Can be monetary fines in the thousands of dollars

18. In the Classroom We have to practice Safety at all Times.

19. Classroom Safety Expectations • Horseplay can cause injuries and is not tolerated during lab/skill activities. • Gloves and goggles are to be worn whenever working with chemicals • Always wash hands after removing gloves. • DO NOT put pencils or pens in the mouth. • Locate and know locations of all fire extinguishers in the laboratory • Return equipment to its proper place. • Clean your workspace after each activity.

20. Classroom Safety Guidelines Cont’ • NEVER use any equipment or supplies without obtaining permission from the instructor. • Notify the instructor IMMEDIATLEY if anything has been spilled. • Place all materials in the appropriate containers upon completion of the laboratory investigation.( Trash, needles, paper) • If there is a fire drill, turn off all electrical equipment, if possible and exit in an orderly fashion. • Know location of exits, safety showers, eye wash station, first aid kit, fire extinguishers, telephone, and fire blanket. • NEVER use any equipment or supplies without obtaining permission from the instructor.

21. Blood borne Pathogens • Taking precautions protects us from disease caused by exposure to body fluids

22. Spills • If you spill anything on the floor you should clean it up and notify the teacher of the incident. ** there could be other procedures that need to be done to ensure student safety**

23. MSDS • A Material Safety Data Sheet (MSDS) is a document that contains information on the potential hazards (health, fire, reactivity and environmental) and how to work safely with the chemical product. • In the 1980s, the OSHA Hazard Communication Standard formally created MSDS content requirements… It includes: • What it is? • What hazards go along with it? • What's in it? • First-aid measures • Fire-fighting measures • Accidental release measures • Handling and storage • Exposure controls/personal protection • Physical and chemical properties • Stability and reactivity • Is it toxic? • How to dispose of it? • How to transport it?

24. What areBody Fluids • ?????????????????????????????????????? • Blood • Blood Products • Semen • Vaginal Secretions • Cerebrospinal Fluid • Saliva • Mucus

25. Proper Lifting

26. Ergonomics • Designing equipment and work tasks to conform to the capability of the worker • It provides a means for adjusting the work environment and work practices to prevent injuries before they occur. • Health care facilities especially nursing homes have been identified as an environment where ergonomic stressors exist.

27. Ergonomics • Strongest muscles in the body are the legs • When lifting always lift with your legs • Always use proper body mechanics • Always bend at the hips and knees • Back injury is the most common injury experienced by. the health care worker

28. Disease that we should be most concerned about spreading through body fluids? • Hepatitis B Virus • HIV and AIDS • HIV: Human Immunodeficiency Syndrome Virus • AIDS: Acquired Immunodeficiency Syndrome • Other Hepatitis viruses are of concern as well.

29. Flu Viruses • H1N1 flu • Traditional flu

30. Prevention • Cover your cough • Hand washing saves lives

31. AED’s are Located in 4 locations throughout the school • ???????????????????????????????????? • To the left of the bank • In athletic trainers office • Football field • In front of the main gymnasium

32. AED’s • Automated External Defibrillator • Used to restart the heart if someone goes into cardiac arrest due to an irregular heart rhythm. Ventricular tachycardia Ventricular Fibrillation
