ERECTION OF SCAFFOLDING

PRESENTED BY

SAKET AGRAWAL- AB16021

PROCEDURE SELECT A SECURE FOUNDATION ON WHICH TO BUILD AND SET YOUR SCAAFFOLD.

OBTAIN MUD SILLS OR BASE PLATE TO ATTACH THE SCAFFOLDING TO MAKE THE FOOTING MORE STABLE.

IF THERE IS UNLEVEL GROUND DIG DOWN TO MAKE THE DIRT LEVEL IN ANY HIGH CORNER.

LAY OUT THE ENDS OF THE SCAFFOLDING .LIFT ONE END PIECE,AND ATTACH THE UPPER CROSS BRACE.

THE FAR END OF THE BRACE SHOULD BE THE END PIECE WHILE LIFTING THE SECOND END PIECE AND ATTACH IT UPPER CROSS BRACE.

LIFT THE PLANKS THROUGH THE SCAFFOLD BARS AND INTO PLACE. HARDWARE SHOULD BE INCLUDED TO FASTEN THE PLANKS INTO PLACE.

GUARDRAILS ARE HIGHLY RECOMMENDED FOR ALL SCAFFOLDING DUE TO HEIGHT OF THE EQUIPMENT AND THE RISK OF FALLS.

ALSO CONSIDER USING TIE OFFS AND OTHER FALL PROTECTION.

BEFORE USING SCAFFOLDING EXAMINE IT TO MAKE SURE ALL PIECES ARE SECURE.

HAZARDS INVOLVEDABOUT 65% OF ALLL ALL CONSTRUCTION WORKERS USE SCAFOLDING IN THEIR DAILY WORK.

SOME OF HAZARDS INVOLVED IN ERECTION OF SCAFFOLDING ARE:-

1. FALLS FROM HEIGHT

2. SLIP AND FALL

3. COLLAPSE

4. STRUCK BY FALLING OBJECT

CONSIDERATIONS THE BOTTOM TIE TO THE BUILDING MUST BE PLACED NO HIGHER THAN FOUR TIMES THE

MINIMUM BASE WIDTH AND EVERY 26 FEET VERTICALLY THEREAFTER. THE TIES MUST BE PLACED AS CLOSE TO THE TOP AS POSSIBLE IN CASE THEY ARE LESS THAN FOUR TIMES THE MINIMUM BASE WIDTH OF THE SCAFFOLDING.

VERTICAL TIES MUST BE PLACED AT THE END OF THE SCAFFOLDING AND AT NO MORE THAN 30 FEET HORIZONTAL INTERVALS.

THE TIES MUST BE INSTALLED AS THE ERECTION PROGRESSES AND NOT REMOVED UNTIL THE SCAFFOLDING IS DISMANTLED TO THAT HEIGHT.

THE SCAFFOLD DISTANCE FROM A 220-VOLT LINE MUST BE AT LEAST 3 FEET.

SIDE BRACKETS, CANTILEVERED PLATFORMS, PULLEYS OR HOISTS AND WIND CONDITIONS MUST BE CONSIDERED AND COMPENSATED WITH ADDITIONAL TIES/OR GUIDES.

GUARDRAILS ARE REQUIRED ON WELDED FRAME SCAFFOLDS THAT ARE 10 FEET HIGH OR MORE. TOP RAIL HEIGHT MUST BE 36 INCHES TO A MAXIMUM OF 45 INCHES. TOP RAILS MUST BE ABLE TO WITHSTAND AT LEAST 200 POUND OF OUT WARD PRESSURE AND MID RAILS AT LEAST 150 POUNDS.

CROSS BRACING IS ACCEPTABLE IN PLACE OF GUARDRAILS, IF THE CROSS BRACING IS BETWEEN 20 AND 30 INCHES ABOVE THE PLATFORM. CROSS BRACING BETWEEN 38 AND 48 INCHES ABOVE THE PLATFORM MAY SERVE AS THE TOP RAIL.

SOME BAD PRACTICES DURING ERECTION SCAFFFOLDING

(A) (B)

IN THIS NO GUARDRAILS IN THE IN THIS NO PLATEFORM IS GIVEN TO STAND

SCAFFOLDING.

INCREASE THE POSSIBILITY OF FALLING

FROM HEIGHT.

NOT USING SAFETY BELT WHILE

WORKING AT HEIGHT.

SOME GOOD PRACTICES DURING ERECTION OF SCAFFOLDING

PROPER PLATEFORM IS GIVEN TO STAND GUARDRAILS ARE PROVIDED TO PREVENT FROM

AND WORK. FALLING FROM HEIGHT.

USE OF SAFETY BELT WHILE WORKING AT HEIGHT

.

GENERALLY WHILE WORKING ABOVE 1.8 METRE

HEIGHT USE OF SAFETY BELT IS MUST.

CONTROL MEASURESFALL FROM HEIGHT:-

SCAFFOLDING MUST BE EQUIPPED WITH GUARDRAIL SYSTEM INCLUDING TOP RAILS MID RAILS AND TOE BOARDS WHEN OVER 10 FEET HIGH UNLESS OTHER FALL PROTECTION METHOD IS USED.

SCAFFOLDING PLATEFORMS MUST BE TIGHTLY PLANKED WITH SCAFFOLDING PLANK GRADE MATERIAL .

SAFETY BELTS MUST WHILE USING SCAFFOLDING.

SLIP AND FALLS:-

EMPLOYEES HALL BE PROHIBITED FROM WORKING ON SCAFFOLD COVERED WITH SLIPPERY MATERIAL EXCEPT FOR REMOVAL OD=F SUCH MATERIAL

WHERE SCAFFOLD PLATEFORM IS SLOPED GREATER THAN 1 IN 8, CLEATS ARE REQUIRED TO PROVIDE FOOTING.

SCAFFOLD STAIRWAYS SHALL HAVE SLIP RESISTANT TREADS AND LANDINGS.

COLLAPSES:-

BASE PLATE MUST BE USED AND MUST BE PLACED ON SOLID FOOTING. SCAFFOLD IS TO BE LEVELED AND PLUMBED.

SCAFFOLD MUST BE SOUND RIGID AND SUFFICIENT TO CARRY ITS OWN WEIGHT PLUS FOUR TIMES THE MAXIMUM INTENTED LOAD WITHOUT SETTLING OR DISLPLACEMENT.

CONTINUE DAMAGED ACCESSORIES MUST BE REPAIRED OR REPLACED.

A COMPITENT PERSON MUST INSPECT THE SCAFFOLFING AND , AT DESIGNATED INTERVALSRE-INSPECT IT.

STRUCK BY FALLING OBJECT:-

AREAS BELOW SCAFFOLD WORK SHOULF BE BARRICATED UNLESS A PROTECTIVE CANOPY IS INATALLED.

TOEBOARDS ARE TO BE USED ALONG THE EDGED OF PLATEFORMS.

PANELLING OR SCREENING MAY BE REQUIRED TO CONTAIN LARGER OBJECTS FROM FALLING.

PROPER TRAINING SHOULD BE GIVEN TO LABOURS.
