CONTENTS:1. INTRODUCTION TO PPE2. NON RESPIRATORY SYSTEM3. RESPIRATORY SYSTEM4. SELECTIVITY OF PPE5. REQUIREMENTS OF PERSONAL PROTECTIVE EQUIPTMENTS6. WORK PERMIT SYSTEM7. CHECK LIST FOR WORK SITE8. HAND TOOLS9. POWER TOOLSINTRODUCTION: PROTECTIVE COSTUMES ARE NECESSARY FOR WORKING IN EXTREMELY HOT OR EXTREMELY COLD ENVIRONMENTS AND HOSTILE ENVIRONMENT.UNDER THE VARIOUS PROVISIONS OF THE FACTORIES ACT AND RULES THERE UNDER SUITABLE PERSONAL PROTECTIVE EQUIPTMENTS IS REQUIRES TO BE PROVIDED TO BE PROVIDED BY THE MANAGEMENTIN INDUSTRY ATEMPTS ARE MADE TO DESIGN PROCESS FOR EFFICIENT AND SAFE OPERATION.


ALL HAZARDS ARE KEPT UNDER CONTROLHOWEVER FOR SAFETY OF OPERATIONS IT IS NECESSARY TO USE PERSONAL PROTECTIVE EQUIPTMENTSIT MUST BE BORNE IN MIND THAT PERSONAL EQUIPTMENTS DOES NOT ELIMINATE HE HAZARDS

SAFETY MANAGEMENT’S FUNCTIONS INCLUDES THE PROPER USAGES OF PPES:1) FORMULATION OF DISPLAY OF RULES NEAR WROK PLACES AND

THEIR IMPLEMENTATIONS2) PROVIDING PERSONAL PROTECTIVE EQUIPTMENTS TO

CONSTTRUCTINS WORKERS AND INDUSTRIAL WOKRERS3) TO CONVINCE AND EDUCATEWORKERS ABOUT THE NEED

OFPERSONAL PROTECTIE EQUIPTMENTS THE RISK OF NOT USING EQUIPTMENTS SHOLUD BE UNDERSTOOD

4) TRAINIG OF WORKERS TO USE THE PERSONAL PROTECTIVE EQUIPTMENTS

5) TO BRING ABOUT SAFETY CULTURE IN WORK PLACE6) TO ANALYZE SPECIFY SELECT AND RECOMMEND PPE


NON RESPIRATORY SYSTEMS:

1. EYE: SENSITIVE TO BRIGHT LIGHT PARTICLE DUST FUMES2. EARS: SENSITIVE TO NOISE SOUND3. FACE: SENSITIVE TO APRTICLE CHEMICALS LIQUIDS FUMES GASES

FLYING OBJECTS4. NOSE LUNGS RESPIRATORY SYSTEMS: SENSITIVE TO CHEMICALS

FUMES DUST POISONOUS GASES5. HEAD NECK ANDTORSO;SENSITVE TO ACCIDENTAL HITTINGS

INSERTION IN ROTATING PART6. LEG AND FOOT: SENSITIVE TO FAILING OF OBJECTS CHEMICALS8) BODY:ELECTRIC SHOCK HEAT AND COLD9) SKIN: HEAT AND COLD


RESPIRATORY: TYPE OF HAZARDS TO WHICH A WORKER IS EXPOSED IS THE BASIS OF SELECTION OF THE RIGHT TYPE OF RESPIRATORY PROTECTIVE EQUIPTMENTS THE HAZARDS MAY BE CLASSIFIED AS UNDER GIVEN THESE ARE KNOWN AS RESPIRATORY SYSTEMS

AIR SUPPLY RESPIRATORY SYSTEMS:a. OXYGEN DEFICIENCY ATMOSPHERE IN CONFINED SPACES SUCH AS

TANKSHOLDS OF THIS SHIPS ETC. MAY CONTAIN AIR WITH OXYGEN CONTENT MUCH LOWER THAN THE NORMAL( 21% BY VOLUME)

b. GASEOUS CONTAMINANTS THSES MAY BE TOXIC OR INERT GASES THE TOXIC GASES MAY PRODUCE A HARMFUL EFFECT EVEN IF THEY ARE PRESENT IN RELATIVELY LOW CONCENTRATIONS THE INERT GASES PRODUCE UNDISERABLE EFFECTS PRIMARILY BY DISPLACEMENTS OF OXYGEN THE TERM GASES INCLUDES VAPORS OF VOLATILE SUBSTANCES.


AIR PURIFYING RESPIRATORS:i. CANISTER GAS MASKS.THIS CONSISTS OF A CANISTER,CONTAINING

APPROPRIATRE CHEMICAL A FULL FACE PIECE AND BODY HARNESS TO HOLD THE CANISTER IN PLACE ON THE BODY OF THE WEARER AIR IS DRAWN THROUGH THE CANISTER BY THE WEARER AND DURING ITS PASSAGE THROUGH THE CHEMICAL IN THE CANISTER THE CONTAMINANT PRESENT IN THE INCOMING AIR IS ABSORBED OR IS NEUTRALIZED.

ii. CHEMICAL CATRIDGE RESPIRATOR THIS CONSISTS OF USUALLY A HALF MASK ATTACHED TO ONE OR TWO CATRIDGES.LIKE CANISTERS ARE FILLED WITH APPOPRIATE CHEMICALS TO ABSORB GASES OR VAPOUR DRAWN THROUGH THEM THIS REPIRATOR IS A NON EMERGENCY GAS RESPIRATOR AND IT SHOULD NOT BE USED IN RESPIRATOR AND IT SHOULD NOT BE USED IN AN ATMOSPHERE DEFICIENT IN OXYGEN LIKE CANISTER GAS MASK CHEMICALS CATRIDGES RESPIRATOR PROVIDES RESPIRATORY PROTECTIONS FOR A PEROID THAT DEPENDS ON THE TYPE OF CATRIDGES USED THE CONCENTRATIONSOF GAS OR VAPOUYR AND THE WEARER ACTIVITY IT IS RECOMMENDED FOR LOW CONCENTRATIONS GASES AND VAPOUR (MAX.OF 0.1% OF ORGANIC VAPOUR


SELECTIVITY OF PPE: A WELDER NEEDS THREE PROTECTIONSi. PROTECTIONS OF EYEii. PROTECTIONS FROM ELECTRIC SHOCKiii. AND CONSEQUENTIAL LOSS OF MUSCLE CONTROL THREE PROLONGED SAFETY MEASURES INCLUDE:

SELECTIONS OF RESPIRATOR:a) NATURE OF THE HAZARDS b) SEVERITY OF THE HAZARDSc) TYPE OF CONTAMINANTSd) CONCENTRATIONS OF CONTAMINANTSe) PERIOD FOR WHICH RESPIRATOR PROTECTIONS MUS BE PROVIDED.


COMMON TYPES OF WORK PERMITS ARE:1. FIRE OR HOT WORK PERMIT2. SAFE ENTRY/VESSEL ENTRY WORK PERMIT3. ACID AREA WORK PERMIT4. WORKING AT HEIGHT PERMIT5. COLD WORK PERMIT 6. ELECTRICAL WORK PERMIT7. EXCAVATION PERMIT

I. FIRE OR HOT WORK PERMIT: THESE PERMITS ARE ISSUED TO CARRY OUT THE FOLLOWING OPERATIONS IN AT SUCH AREAS PROCESSES,EQUIPTMENTS WHERE HOT UNDER NORMAL CONDITIONS IS CONSIDERED TO BE DANGEROUS


WORKS WHICH REQUIRE HOT WORK PERMITS:a. WELDING GAS CUTTING GRIDING METAL CHISELING RIVETING

WORKING WITH OPEN FLAMES ETC

HOT WORKb. USE OF ELECTRIC OPERATED TOOLS UNLESS THEY ARE LAME

PROOF TYPE OR EXPLOSION PROOF TYPE ENTERING OR OPERATING OF MOTOR ARE VEHICLES CRANES OR OTHER INTERNAL COMBUSTION ENGINE DRIVEN VEHICLES IN PROCESSING AREA

c. WORK ON ELECTRICAL TRANSMISSION SYSTEM.


CHECK LIST FOE SAFETY INSPECTION OF WORK SITE: ACCORDING TO THE WORK THE SAFETY PERSON SHOULD PREPARE A CHECK LIST FOR DIFFERENT ACTIVITIES THE BELOW CHECK LIST IS COMMON FOE ALL THE ACTIVITIES.

WORK PERMIT:1. WHETHER VALID WORK PERMIT IS ISSUED TO START ANY WORK?2. PROPERLY FILLED AND SIGNED3. WHETHER ALL CONDITIONS OF THE PERMITS ARE FULFILLED BEFORE

STARTINGTHE JOB?4. AS NOTED IN THE PERMIT, WHETHER COMPLIANCES OF ALL THE

RECOMMEDATIONS ARE ENSURED?5. WHETHER PERMITS ARE AVAILABLE A WORK SITE ALL THE TIMES?6. WHETHER HOT WORK AND BLANKER PERMITS REGISTERED IN FIRE

STATIONS7. WHETHER PERMITS ARE BEING CLOSED AFTER THE COMPLIANCES

OF JOB.


PERSONNEL PROTECTIVE EQUIPTMENTS(PPE):1. SAFETY HELMETS& SAFETY SHOES2. GUM BOOTS(ONLY FOR CIVIL LABOUR WORKING IN MUD)3. SAFETY BELTS WITH LIFE LINE4. GLOVES 5. EAR PLUG(FOR NOISY AREA)6. GOGLES/FACE SHIELD7. FACE PROTECTIONS

HOUSE KEEPING:8. WHETHER WASTE BINS ARE PROVIDED/USED9. ARE PASSAGE WAYS/ WALKWAYS CLEAR?10. IS GENERAL NEATNESS O.K.11. IS THE GROUND FREE FROM OIL GREASE ETC., AND IS NOT FOUND

TO BE SLIPPERY?12. WHETHER UNWANTED MATERIALS AND SCRAP REMOVED FROM THE

SITE ON REGULAR BASIS.


TYPES OF ACCIDENTS ASSOCIATED WITH HAND TOOLS:

1. DUE TO MWRONG OR UNSAFE WAY OF USING THE TOOLS OR2. DUE TTO BAD OR DEFECTIVE CONDITION OF TOOLS3. ACCIDENTS CAN ALSO TAKE PLACE DUE TO THE FAILURE OF USING

RIGHT TOOL FOR RIGHT JOB.4. SOMETIMES ACCIDENTS TAKE PLACE DUE TO UNSAFE OR WRONG

WAY CARRYING THE TOOLS5. ACCIDENTS ALSO TAKE PLACE DUE TO STORING OF TOOLS

UNSAFELY NOW LKET US ANALYZE THE REASONS OR CAUSES FOR THE ABOVE TYPES OF ACCIDENTS.


THE FOLLWING PRECAUTIONARY MEASURES ARE SUGGESTED IN CONNECTION WITH PREVENTION OF HAND TOOL ACCIDENTS:

HAND TOOLS MUST BE PERODICALLY EXAMINED AND MAINTAINED BY COMPETENT PERSONS.THEY SHOULD BE MADE OF GOOD QUALITY MATERIALSTHEY SHOULD BE KEPT IN CABINETS OR RACKS WHEN ARE NOT IN USE.THE WOODEN HANDLES OF TOOLS MUST BE MADE OF BEST QUALITY AND DURABLE WOODONLY AFTER RECEIVING GOOD TRAINING AND SAFETY INSTRUCTIONS THE USE OG HAND TOOLS SHOULD BE PERMITTED BY THE WORKMEN THE WORK BENCH SHOULD BE ADEQUATE DIMESIONS TO FACILITATE ALL OPERATIONS WORKERS SHOULD WORK WITH DUE CONCENTRATIONS OF THIS JOBHAND TOOLS MUST BE KEPT IN THEIR PROPER PLACES IN A SYSTEMAITIC MANNER


SAFETY INSRTUCTIONS FOR USE OF HAND TOOLS1. ALWAYS USE THE CORRECT TOOLS REQUIRED FOR EACH JOB2. DO NOT USE A HAMMER FILE SCREW DRIVER ETC., WITH A BROKEN

SLIPPERY OR LOOSE HANDLE AND REPLACE SUCH HANDLES AND THEN ONLY USE.

3. TOOLS WITH BROKEN OR MUSHROOMED HEADS SHOULD NOT BE USED THESE SHOULD BE DRESSED OR IF CANNOT BE RECTIFIED SHOULD BE DISCARDED.

4. WORNOUT OR OPENED OUT SPANNER MAY SLIP NEVER THEM SPANNERS OF PROPER SIZE SHOULD BE USED FOR EACH JOB NEVER USE A SPANNER WITH A PACKING OR LEVERAGE

5. WHILE USING WRENCHES APPLY PULLING EFFORT NEVER PUSH IT.6. NEVER ADOPT WRONGUSES OF HAND TOOLS E.G- USING SPANNER

IS PLACE OF A HAMMER USING A PULLER IN PLACE OF A SPANNER USING A CHISEL IN PLACE OF A SCREW DRIVER USING A SCREW DRIVER FOR OPENINGS BOXES.

7. SUCH PRACTICES DAMAGE THE TOOLS AND ALSO CAUSE ACCIDENTS.


POWER TOOLS:

PORTABLE ELECTRIC TOOLS WITH METAL BODY SHOULK BE EQUIPPED WITH 3 WIRE CORD HAVING THE GROUNG WIRE PERMANENTLY CONNECTED TO THE TOOL FRAME AND MEANS FOR GROUNDING THE OTHER END.

USE OF MULTI METER SHOULD BE MADE FOR CHECKING OF PRESENCE OF ELECTRIC SUPPLY VOLTAGE INSTEAD OF TESTER.

PIPE OR OTHER EXTENSIONS SHOULD NOT BE USED ON A WRENCHES HANDLE TOP INCREASE THE LEVERAGE UNLESS THE WRENCHES IS SPECIALLY DEAIGNED FOR SUCH AN EXTENSIONS


SAFETY INSTRUCTIONS FOR USE OF POWER TOOLS:

1. WHILE USING PORTABLE POWER TOOLS CHECK FOR BROKEN PLUGS WORN OUT OR LOOSE CORDS EARTHING CONNECTION ETC

2. IF DEFECTIVE GET IT RECTIFIED AND THEN ONLY USE IT3. ENGAGED THE COUPLINGS PROPERTY AND BLING THEM WITH

BINDINGS WIRE4. ENSURE ALL THE CONNECTIONS ARE SECURE BEFORE STARTING

OPERATIONS5. DO NOT OPERATE WITH DEFECTIVE EQUIPTMENTS6. ENSURE USE OF EAR PROTECTIONS IN CASE OF NOISY OPERATIONS7. ENSURE ALL MOVINGS MACHINERY PARTS ARE GAURDED?COVERED

PROPERLY8. WHILE WORKING WITH VIBRATING TOOLS TAKE FREQUENT BREAKS 9. DO NOT USE COMPRESSED AIR TO CLEAN YOUR BODY PARTS.
