6) safety fire safety & electrical safety(engr. ding)

  1. 1. School ESH Inspection Safety in Schools 2011
  2. 2. What is FIRE? Is a chemical reaction known as combustion. Rapid oxidation of combustible materials accompanied by the release of energy in the form of heat, light, and flame. FIRE : FIRE SAFETY
  3. 3. FUEL THE FIRE TETRAHEDRON HEAT OXYGEN CHAIN REACTION
  4. 4. or oxidizing agent is a nonflammable gas that is a basic requirement for life. Atmosphere contains 21 % O 2 . For fire to occur, there must be at least 16% O 2 . Some fuel as low as 4 % O 2 is needed to support combustion. OXYGEN : FIRE CHEMISTRY
  5. 5. is the energy necessary to increase the temperature of a fuel to a point where sufficient vapors are given off, with this ignition will occur . HEAT : FIRE CHEMISTRY
  6. 6. FIRE CHEMISTRY or reducing agent which can be solid, liquid, or gas (vapor) form. Except in gas form,the fuel must generally undergo changes to become a vapor before combustion can take place. FUEL:
  7. 8. FIRE CHEMISTRY CHEMICAL CHAIN REACTION
  8. 9. FUEL HEAT OXYGEN CHAIN REACTION
  9. 10. Fire Safety & Prevention
  10. 12. <ul><li>PREVENTIVE MEASURES </li></ul><ul><li>Identify and report fire hazards and unsafe work practices. </li></ul><ul><li>Unplug all electrical equipment when not in operation, unless necessary. </li></ul><ul><li>Maintain office sanitation and proper housekeeping </li></ul><ul><li>Familiarize and keep emergency exits marked, lighted and free from any obstruction. </li></ul><ul><li>Familiarize location of fire alarm, fire extinguishers and other fire fighting equipment. </li></ul><ul><li>Enforce “No Smoking” policy and report violators. </li></ul><ul><li>7. Welding work should have work permit and fire extinguishers at hand for the duration. </li></ul>Electrical Safety and Prevention
  11. 13. <ul><li>Voltage – a measure of electrical force </li></ul><ul><li>Current – the movement of electrical charge </li></ul><ul><li>Resistance – opposition to current flow </li></ul><ul><li>Conductors – substances, such as metals, that have little resistance to electricity </li></ul><ul><li>Insulators – substances, such as wood, rubber, glass, and bakelite, that have high resistance to electricity </li></ul><ul><li>Grounding – a conductive connection to the earth which acts as a protective measure </li></ul>Electrical Safety and Prevention
  12. 14. 2. Electrical Services a. Electrical wiring in new construction shall be installed in accordance with the provision of the Philippine Electrical Code. b. Receptacles and outlets services by extension cord type wiring are prohibited. Electrical appliances shall be grounded. c. Special protective receptacle covers shall be installed in all areas occupied by children in centers for children under five (5) years of age. AS INDICATED BY REPUBLIC ACT 9514 (FIRE CODE OF THE PHILIPPINES OF 2008) DIVISION 9. EDUCATIONAL OCCUPANCIES Electrical Safety and Prevention
  13. 15. Common Electric Wire sizes
  14. 16. Electrical Safety & Prevention
  15. 18. <ul><li>Do plug power equipment into wall receptacles with power switches in the Off position. </li></ul><ul><li>Do unplug electrical equipment by grasping the plug and pulling. Do not pull or jerk the cord to unplug the equipment. </li></ul><ul><li>Do not drape power cords over hot pipes, radiators or sharp objects. </li></ul><ul><li>Temporary or permanent storage of any materials must not be allowed within 3 feet of any electrical panel or electrical equipment. </li></ul>Do’s and Don'ts
  16. 19. <ul><li>Do check the receptacle for missing or damaged parts. </li></ul><ul><li>Do not plug equipment into defective receptacles. </li></ul><ul><li>Do check for frayed, cracked, or exposed wiring on equipment cords. </li></ul><ul><li>Employees should know the location of electrical circuit breaker panels that control equipment and lighting in their respective areas. Circuits and equipment disconnects must be identified </li></ul>Do’s and Don'ts
  17. 21. <ul><li>Do check for defective cords clamps at locations where the power cord enters the equipment or the attachment plug. </li></ul><ul><li>Extension cords should not be used in office areas. Generally, extension cords should be limited to use by maintenance personnel </li></ul><ul><li>“ Cheater plugs”, extension cords with junction box receptacle ends or other jury-rigged equipment should not be used. </li></ul>Do’s and Don'ts
