PROHIBITION SIGNS
THEY COMMAND A CERTAIN ACTION (BLUE)
MANDATORY SIGNS
THEY WARN AGAINST A DANGER OR RISK. (YELLOW)
WARNING SIGNS
THEY SHOW ESCAPE ROUTES, EMERGENCY DOORS; FIRST AID DEVICES
OR THe wAy To THeM (GREEN)

CARRIED ON AIRCRAFT FOR EMERGENCIES TO SUPPORT BREATHNG AT HIGH ALTITUDES IN THE EVENT OF A CABIN PRESSURE LOST.
PRESSURIZED OXYGEN
CAUSES SPONTANEOUS COMBUSTION WHEN IN CONTACT W/ OILS OR GREASES
Oxygen
ARE EASY COMBUSTIBLE DUE TO THE CARBON IN THEIR MOLECULAR STRUCTURE AND THEIR LOW FLASH and IGNITION POINT
OILS and GREASES

EMERGENCY AND CATASTROPHE PROTECTION AND/OR THE LIMITATION OF DAMAGES IN CASE OF EMERGENCIES.
ALARM ORDER (AO)
IS RELATED TO LOCAL ACCIDENTS (FIRE AND MATERIAL DAMAGE
ALERT PHASE I
IS RELATED TO CRISIS TYPE EMERGENICY SITUATION
ALERT PHASE II
DEFINES THE METER AS THE UNIT OF LENGTH AND THE KILOGRAM
AS THe UNIT OF MASS
INTERNATIONAL SYSTEM OF UNITS
IS BASED ON A DISTANCE EQUAL TO ONE TEN- MILLIONTH OF THE DISTANCE FROM THE EQUATOR TO THE POLES MEASURED ALONG A MERIDIAN, ALONG
THE EARTH SURFACE
METRIC LENGTH SYSTEM / Length of a meter
ITS UNIT OF LENGTH, TIME AND WEIGHT ARE THE INCH, SECOND AND POUND.
IMPERIAL SYSTEM
IS USUALLY GIVEN FOR ALL DIMENSIONS ON A DRAWING AND IS STATED IN A PRINTED BOX ON THE DRAWING.
GENERAL TOLERANCE
THE DIFFERENCE BETWEEN THE BASIC DIMENSION AND THE UPPER OR LOWER LIMIT
ALLOWANCE / TOLERANCE
ARE FOUND IN ALMOST ALL TOOL KITS IN BOTH 6 AND 12-INCH LENGTHS (15-30 cm)
STEEL SCALES / STEEL RULES
VERY USEFUL INSTRUMENT FOR TAKING MEASUREMENT UP TO SEVERAL FEET.
FLEXIBLE STEEL TAPE
(TO MINIMIZE THE POSSIBILITY OF READING (PARALLAX) ERROR) EYE SHOULD BE AS NEAR AS POSSIBLE
MOST COMMON TOOL FOR TESTING SQUARENESS OF COMPONENTS AND PARTS
TRI SQUARE
CONSISTS OF A HALF ROUND DIAL THAT IS GRADUATED FROM 0 to 180° AND IS SUITED FOR MEASURING ANGLES OF COMPONENTS AND PARTS
Protractor
ARE USED TO MEASURE EITHER INSIDE OR OUTSIDE RÄDII

MARKING ON THE MATERIAL ALL THE LINES AND POINTS WHICH ARE
NeEDED TO wORK with
MARKING OUT
MARKING OUT RULES
1. NEVER USE A LEAD PENCIL ON TITANIUM, THE CARBON, WHEN HEATED CAN INFUSE THE METAL
AND CAUSE CRACKING
2. FOR MARKING OF ALUMINUM ALLOY USE ONLY SOFT LEAD PENCIL
(EXCEPT FOR CUT -LINES, WHEN SCRIBER MAY BE USED)
3. MARK PREFERABLY THIN LINES AND MARK LINES ONLY ONCE
4. WHEN WORKING WITH ALUMINUM PARTS ONLY SOFT LEAD PENCIL MAY BE USED FOR LAYOUT WORK
5. FOR MARKING OUT LENGTH, A RULE OR STEEL TAPE IS USED
6. TRI-SQUARES ARE USED FOR MARKING OUT RIGHT ANGLES
USED FOR SCRIBING ARCS, AND CIRCLES, FOR MEASUFING BETWEEN POINTS
AND FOR TRANSFERRING DIMENSIONS
DIVIDERS
IS USED TO MARK PERMANENT LINES ON COMPONENT OR PART OF SURFACE
Scriber
HAS A VERTICAL BEAM SCALE FIXED TO A FLAT BASE.
VERNIER HEIGHT GAUGE
USED ON A SURFACE PLATE OR A MARKING OUT TABLE
VERNIER HEIGHT GAUGE
TO COMPARE MEASURED, DATA OF THE INSPECTION TOOL WITH THE TRUE VALUE OF tHE MEASUREMENT VALUE.
CALIBRATING
IS THE AMOUNT OF ROTATIONAL FORCE APPLIED WHEN TIGHTENING A FASTENER
Torque
PREVENT OVER-TIGHTENING ACCURATE APPLICATION OF TORQUE IS ACHIEVED BY TORQUE WRENCH
Torque
CALIBRATED IN INCH-POUNDS OR FOOT - POUNDS (iMPERIAL) OR Nm (METRIC)
Torque
SHOW THE ACTUAL TORQUE ON A MECHANICAL SCALE, A DIAL GAUGE OR AN ELECTRONIC SCALE (MEASURING WRENCH)
INDICATING TORQUE WRENCH
ARE PRESET TO THE DESIRED TORQUE VALUE AND ARE STARTING A SIGNAL WHEN TORQUE IS REACHED (CLICK WRENCH)
SIGNALLING TORQUE WRENCH
CALIBRATION IS DONE EITHER EVERY 6 MONTH OR ANNUALLY
CONTROL FRICTION AND WEAR BY INTRODUCING A FRICTION - REDUCING FILM BETWEEN MOVING SURFACE IN CONTACT THEY MAY BE FLUID, SOLID OR PLASTIC
LUBRICATION

Lubrication
DERIVED FROM CRUDE OIL, CRUDE OIL CONSISTS OUT OF CARBON HYRIDE
Mineral Oil
ARE MANUFACTURED BY CHEMICAL REACTIONS WHICH HAVE AN ADVANTAGE TO CONCERNING A CONSTANT COMPOSITION AND QUALITY
Synthetic oil
IS A LUBRICANT COMPOSED OF OIL AND SOMETIMES THE OIL IS THICKENED WITH SOAP OR OTHER, THICKENER TO MAKE A SOLID OR SEMI- SOLID PRODUCT
GREASE
CONCENTRATE THE FORCE FROM A HAMMER BLOW TO THE INMEDIATE AREA OF THE PUNCH TiP
PUNCHES
GENERALLY COMPOSED OF STEEL, BUT CAN ALSO BE MADE OF COPPER OR BRONZE
PUNCHES
THIS HELPS TO PREVENT WANDER WHEN STARTING TO DRILL A HOLE
CENTER PUNCH
IT’S TIP IS GROUND TO AN ANGLE OF APPROXIMATELY 60° AND IS USED
TO MAKE INDENTATIONS IN METAL.
Center punch
INCORPORATES AN ADJUSTABLE SPRING LOADED, TRIP MECHANISM, NEGATING THE REQUIREMENT FOR A HAMMER
AUTOMATIC CENTER PUNCH
THIS IS USED TO START WHEN DRIVING OUT A BOLT OR PIN
DRIFT (TAPER) PUNCH
ONCE THE TAPER ALMOST FILLS THE BOLT - HOLE THE JOB SHOULD BE FINISHED WITH A PIN PUNCH TO PREVENT DAMAGE OF THE HOLE
