  • 6

    is the fifth and last S which means we have to do this process without prodding

    Shitsuke/Self- Discipline/Sariling kusa

  • 7

    can eliminate some workplace hazards and help get a job done safely and properly.

    Effective housekeeping

  • 8

    can frequently contribute to accidents by hiding hazards that cause injuries.

    Poor housekeeping

  • 9

    Benefits of Good Housekeeping

    Maintains safe and healthy work conditions Saves time, money, materials, space and effort Improves productivity and quality of work Boosts morale Reflects a well-run organization

  • 10

    Electric accidents are classified into:

    electric shock eye injury Fire or explosion

  • 11

    caused by contact with charged or leaked parts of electric facilities

    electric shock

  • 12

    caused by strong light from arc welding work

    eye injury

  • 13

    ignited by overheat, sparks, leakage current, static charges, and the like

    fire or explosion

  • 14

    CIRCUIT PROTECTION DEVICE:

    Fuses Circuit breakers Ground fault circuit – interrupters (GFCIs)

  • 15

    is a supersensitive appliance, rapid action power switch which breaks a circuit when where is more than 5 milliamps difference between the hot wire and the neutral or grounded conductors.

    Ground fault circuit – interrupter (GFCI)

  • 16

    is the most serious electrical hazard. This happens when you touch a live wire, a tool or machine with poor insulation. You then become a conductor.

    Electrical Shock

  • 17

    The minimum current at which a man feels an electric shock is about

    1 mA at 60Hz

  • 18

    the limit current at which man endure the pain of an electric shock is about

    7 to 8 mA

  • 19

    maximum current at which man can still move is about

    10 to 15 mA

  • 20

    Other Types of Safeguarding

    InterlockedGuard Restraint Device Two-Hand Control Gate

  • 21

    When this type of guard is opened or removed. The tripping mechanism and/or power automatically shuts off or disengages, and the machine cannot cycle or be started until the guard is back in place.

    InterlockedGuard

  • 22

    Use cable or straps attached to the operator’s hands and a fixed point Must be adjusted to let the operator’s hands travel within a predetermined safe area Hands - feeding tools are often necessary if the operation involves placing material into the danger area

    Restraint Device

  • 23

    Requires constant, concurrent pressure to activated the machine The operator’s hands are required to be at safe location (on control buttons) and at a safe distance from the danger area while the machine completes its closing cycle

    Two-Hand Control

  • 24

    Movable barrier device which protects the operator at the point of operation before the machine cycle can be started

    Gate

  • 25

    is the result of chemical combination of a combustible fabric (fuel) with oxygen within the nearness of sufficient warm

    Fire

  • 26

    In case any one of the three is lost, a fire will not begin. The relationship is called

    Fire Triangle

  • 27

    Basic Chemistry of Fire

    Fuel Oxygen Heat Chemical Reaction

  • 28

    combustible materials. This includes many substances such as natural gas (methane), plastics, wood, natural and artificial fibers, paper, coal and other living matter.

    Fuel

  • 29

    Fine normally draws its fire through the air, which is a mixture of 21 percent oxygen and 78 percent nitrogen.16% of oxygen is needed to sustain fire

    Oxygen

  • 30

    Sufficient _____ to raise the temperature of the fuel and oxygen occurs.

    Heat

  • 31

    Vapors of gases, which are distilled during burning process of a material, are carried into the flame

    Chemical Reaction

  • 32

    Three Methods of Heat Transfer

    Conduction Convection Radiation

  • 33

    Is the transfer of thermal energy between neighboring molecules in a substance due to a temperature gradient. It takes places in solids, such as metal, timber, concrete and glass.

    Conduction

  • 34

    Is one of the major modes of heat transfer. It takes the place in fluids and gases cause by convection currents.

    Convection

  • 35

    Is electromagnetic radiation emitted from a material which is due to the heat of the material. The characteristics of which depend on its temperature. It is the process of heat transmission though air and gases.

    Radiation

  • 36

    Hot surface produced by defective electrical equipment are a common source if ignition.

    Electrical equipment

  • 37

    If some liquids are heated or sprayed to a very hot surface, it may ignite spontaneously without a present ignition source.

    Spontaneous Ignition

  • 38

    Is a type of combustion which occurs without an external ignition source. Combustion begins if a sufficiently strong oxidizer, such as oxygen, is present.

    Spontaneous Combustion

  • 39

    In may workplaces, employees smoking, or other persons smoking in a certain area. Can be a source of fire.

    Smoking

  • 40

    Sparks can be created by friction, for instance where the moving part of a machine comes to contract with a fixed part, or two moving surfaces rub each other or slide together during machine operation.

    Friction

  • 41

    n vehicle maintenance, and parking areas, diesel-petrol engine, vehicle emissions and hot surface like exhaust systems can be a source of ignition

    Engines, Vehicle Emissions and Hot Surface

  • 42

    Open flame in the workplaces such as boilers, furnaces, portable heating appliances, etc. can be also a source of ignition.

    Open Flame Sources

  • 43

    In limited cases, _____ can be a source of ignition.

    Lighting

  • 44

    Fires involving wood, paper, cloth, trash and other ordinary materials.

    Class A

  • 45

    Fires involving flammable liquids such as gasoline, thinners, oil-based paints and greases.

    Class B

  • 46

    Fires involving energized electrical equipment, where a nonconducting gaseous clean agent or smothering agent is needed. The most common type of extinguisher for this class is a carbon dioxide exinguisher.

    Class C

  • 47

    Fires involving combustible metals such as magnesium, sodium, potassium, titanium, and aluminum.

    Class D

  • 48

    Fires involving commercial cooking appliances with vegetable oils, animal oils, or fats at high temperatures.

    Class K

  • 49

    means putting everything in its proper place. It is everybody’s business to observe it in the workplace.
