WORKING at HEIGHTS If only I was wearing a safety harness !!
Working at Heights Presentation Contents
Mobile Elevated Working Platforms
Fall Speed v’s Reaction Time
Falls are the number one cause of fatalities in the construction industry accounting for approximately 56% of all fatalities
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:-
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 : 4 up – 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:-
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:-
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 metal-reinforced ladders, make sure there are no electrical hazards in the near vicinity
“ No matter how quickly a job can be done, there is always time to fall”
The Roof: A Risky Place To Be Before Working on 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-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:-
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
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. 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
Mobile Scaffold Towers
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
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
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
Mobile E levated W ork P latforms
Good body reaction time
= 0.2 seconds
Travel distance in 0.2 seconds = 2m
In 1 second your body will fall 10m FALL SPEED V’s REACTION TIME By the time you react your body will be 2m below where you were standing
Limits free fall to within 2 vertical metres of the initiation point which reduces force by decreasing fall distance
Consists of a(n)
Full Body Harness
Fall Protection Lanyard 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
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 Fall-Arrest Shock Absorbing Lanyards: Material in the pack tears absorbing shock and reducing risk of injury. Available with web or rope lanyards. Expandable Lanyard: Especially useful for scaffolds, steel erectors and construction workers where tripping might be a risk. Twin Tailed Lanyard: The expandable twin tailed lanyard is an ideal choice for situations where 100% tie-off is required.
Fall Protection Anchorage Point A secure point of attachment for lifelines, lanyards or deceleration devices
Anchorage points used for attachment of personal fall arrest equipment must be:
Located at or above the employee’s waist
Capable of supporting more than 2270kg per employee
Designed and built to hold the maximum force of the fall arrest
Full body harness:
The attachment point of a body harness is located in the center of the wearer’s back near shoulder level
Body belts are not allowed on sites
Snaphooks shall be a double locking-type
WHAT YOU NEED?
Full body harness complete with rear dorsal ring (EN 361)
1.75m fixed length lanyard (EN 362)
Shock absorbing device (EN 355)
55mm opening scaffold hook for one handed operation (EN 362)
Care for fall arrest systems:
After a fall arrest, the equipment will no longer be used (equipment will be disposed 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
Working at Heights
No job is so important that it cannot be done safely
UNDER NO CIRCUMSTANCES ARE PERSONS WORKING ON THIS SITE TO PUT THEMSELVES IN DANGER
