Protection

Falls are the number one cause of fatalities in the

construction industry accounting for approximately 56% of  all fatalities

THE PAST 

All employees shall be protected from falls of 2m or more by

the use of an approved fall protection system

Railings are required at permanent elevated locations

greater than or equal to 1.3m

Lethal Ladders: Make sure the ladder is:is:

Right for the job. Would scaffolding or a cherry picker be better?



In good shape.



Secured near the top.



On a firm base and footing: footing: 4 up  ²  ² 1 out



Rising at least 1 meter beyond the landing place OR that there is a proper hand hold.



Always have a firm grip on the ladder and keep a good balance.



Keep you hands free and tools in a shoulder bag or belt attachment

Lethal Ladders: Use of Ladders:Ladders: Work should only be carried out from a ladder when the job is of  short duration and can be carried out safely. 





For added safety the base of the ladder should be staked or buried to prevent slipping. Ensure your footware is free from excessive mud or grease  before you climb up the ladder. ALWAYS Face the ladder.

Lethal Ladders: Hazards of Ladders:Ladders: Don¶t stand ladder on drum, box or other unstable base 

 Never attempt to repair broken ladders



 Never carry loads up ladders  ±  ±  hoist it up



Ladder rungs must not be used as improvised ramps



When

using metel or metalmetalreinforced ladders, make sure there are no electrical hazards in the near vicinity

Ladder Safety ´No matter how quickly a job can be  done, there is always time to fallµ 

Unsafe

Safe

The Roof: A Risky Place To Be Before Working on Roofs:Roofs:  Fragile materials should be identified and precautions decided 

Roof edge barriers (or scaffolds) must be erected tp prevent people and materials falling



Access ladders must be a safe distance above the stepping stepping--off point and must be secured



Where

access ladders rise above 9meters a safe intermediate platform must be provided

The Roof: A Risky Place To Be Hazards of Working on Roofs:Roofs: 

If you can fall more than 2 meters, guardrails and toe  boards must be erected



Hazards resulting from adverse weather conditions must  be anticipated, and suitable precautions taken

 Wet windy or Icy

weather can seriously affect safety



Scaffolding

Using ladders or

scaffolding without proper fixing is

crazy 

Putting up scaffolding, removing ties and taking it down again is a job for trained and experienced scaffolders scaffolders.. Leave it to them   Never use incomplete scaffolding always inspect before use 

Make sure there is safe access, hand rails and toe boards at all edges



Things fall on sites, wear your  helmet



Always ensure the GREEN TAG  before usin the scaffoldin

Mobile Scaffold Towers Before    

Erection:

Check

all components are in good condition Check wheels for effective rotation Check brakes and locking devices work  correctly Prior to erecting towers on suspended floors, ensure bearing capacity of floor is sufficient for the planned load

Before Use: 

Ensure the tower is vertical and square  Towers must not be used unless the wheels are locked  Check that outriggers are set correctly and secured  Ensure the platform is fully boarded out and guardrails and toe boards are fitted if working  platform is over 2 meters

Mobile Elevated Work Platforms

Mobile Elevated Work Platforms  Do    

  

not operate without pre-use inspection and unless you are trained Check condition of tyres, toe boards and guardrails, look for  leaking hydraulic fluids Look out for overhead obstructions such as power cables, unstable ground, other equipment or personnel near-by Only use on firm level ground, make sure outriggers are properly extended and chocked before raising the platform Always wear a safety harness secured to the platform by lanyard. Safety means staying in the basket and not climbing on the guardrails Place barricades and warning signs around the planned working radius Traveling with a boom, is always in the direction of travel and at creep speed and only if equipment is designed to allow this Know what to do if machine fails with platform in raised position

FALL SPEED V·s REACT ION TIME

In 1 second your body  will fall 10m Good

body reaction time = 0.2 seconds  T  T ravel distance in 0.2 seconds = 2m

By the time you react your body will be 2m below where you were standing

Fall Protection Fall arrest:  L imits

free fall to within 2 vertical metres of the initiation point which reduces force by decreasing fall distance

 Consists

of a(n)

 ²  L anyard ² Anchorage Point ² Full Body Harness ² Attachment Strap

Fall Protection L anyard

A device made of rope, wire or nylon strap used to connect the individual to an anchorage point and stop the individual in the event of a fall

Lanyards should: 

Be inspected prior to use



Be protected against being cut or abraded



Have a minimum breaking strength of 2270kg



Be the appropriate length



Be attached to an anchorage not to itself 

Safety Equipment for FallFall-Arrest Shock Absorbing L anyards: Material in the pack tears absorbing shock and reducing risk of injury. Available with web or rope lanyards.

 T win  T ailed L anyard:

Expandable L anyard: Especially useful for scaffolds, steel erectors and construction workers where tripping might be a risk.

 T he

expandable twin tailed lanyard is an ideal choice for situations where 100% tie tie--off is required.

Fall Protection Anchorage Point  A  secure

point of attachment for  lifelines, lanyards or deceleration devices 

Anchorage points used for attachment personal fall arrest equipment must be:

of  



Located at or above the employee·s waist



Capable of  of supporting more than 2270kg 2270kg per employee



Designed and built to hold the maximum force of the fall arrest of 

Fall Protection Full body harness: 

The attachment point of of  a body harness is located in the center of of  the wearer·s back near shoulder level



Body belts are not allowed on sites



Snaphooks shall be a double locking locking--type

WHAT YOU

NEED?





1.75m fixed length lanyard (EN 362)



Shock absorbing device (EN 355)



55mm opening scaffold hook for one handed operation (E N 362)

Fall Protection Care for fall arrest systems: 

After a fall arrest, the equipment will no longer be used (equipment will be disposed of  of or destroyed)



Clean equipment after use



Air dry equipment, do not hang in direct sunlight



Store equipment in a cool, dark, dry well ventilated place
