Regulations - Summary
• Like LOLER (Lifting Operations and Lifting Equipment Regulations. more in L2B)
•
The planning should include emergency planning and rescue plans
•
Employers must ensure people are competent and supervised
•
It is the duty of employers to make sure that work actually needs to be done at height
•
Equipment should be selected by considering collective protection measures in
preference to personal protection measures
•
Employers should ensure that objects or materials cannot fall from a height
•
The regulation also contains the phrase "Every employer shall ensure no material or
object is thrown or tipped from a height in circumstances where it is liable to cause injury to any
person
•
Identify areas where people might fall a distance or where objects may fall and strike
people
•
Generally all equipment used in work at height must be inspected at 'suitable intervals'
particularly equipment likely to be damaged from normal use, i.e. slings, grillons
•
Inspections must be carried out by a competent person, so we get someone in to check
the WaH kit every 6 months
•

Harnesses
• Pre use check
• How to put it on
• Uses:
– Work restraint
– Work positioning
– Fall arrest
L2A WaH Training (November 12)
Helmets
• Pre use check
• Putting it on
– adjusting
L2A WaH Training (November 12)
Carabineers
• Pre use check
– Does it open and lock
• Axis of load
• Always lock
L2A WaH Training (November 12)
Work Restraint
• Harness takes no load
• Unable to get into the position where a fall is
possible
• E.g.
– Working on a roof
L2A WaH Training (November 12)
Work Positioning
• Supported by the harness
• Generally positioned hanging next to the work
L2A WaH Training (November 12)
Fall Arrest
• Not taking load in normal use
• Must always have a connection
• Y-Lanyards
L2A WaH Training (November 12)
Fall Arrest
• Rope grab
– ASAP
– Rocker

Rescue Plan
•
•
•
•
•
•
What if things go wrong?
Always have a plan
Rescue using ladder
Rescue using genie
Rescue by going up there
Do not work at height without a rescue plan
L2A WaH Training (November 12)
PPE Inspection
• Pre use checks
• Regular inspection
L2A WaH Training (November 12)
Using Wire ladders
•
•
•
•
•
Few different ways to climb
Some people like them footing, some don’t
Usual access method to access gantries
Uses vertical running line with Rocker or ASAP
Take care with:
– Twisted rungs (usually at bottom)
– Lacing hooks on boots (can hook onto wire)
• Don’t rely on these ladders as an escape route
unless you have relevant competence and
confidence
L2A WaH Training (November 12)
Using Gantries
• They are ‘safe’ work areas like grids
• No loose items in pockets
• No need for a harness once in the gantry, unless:
– There are parts of the floor missing, or you are removing bits of
floor
– You are leaning out through/below the handrails
– You are climbing on the handrails
• Do not leave holes in floor unless they are obvious
• Do not trap cables in floor – tape/hang them from the
handrails
• Don’t use the window-sills
• (e.g. to walk between gantries)
L2A WaH Training (November 12)
Using the Space-Frame
•
•
•
•
•
•
Use fall-arrest lanyards on lower box section
Nothing in pockets
Can sit in nodes
No drinks
Always keep your rope
Access via the gantries
L2A WaH Training (November 12)
Using the T2 Truss
•
•
•
•
•
•
Access via wire-ladder
Grip provided on all four cords for walking
Four locations for attaching puzzle-blocks
Maximum of two people
Be careful of hot or fragile lights
Ideally walk on the opposite side to the one
your fall-arrest lanyard is attached to
L2A WaH Training (November 12)
What to take with you?
• As little as possible, but it is a good idea to
have a:
– Harness
– Hard-hat
– Y-Lanyard
Absorbica
– Grillon
– Rope
L2A WaH Training (November 12)
Rope Work
• WaH usually means doing some rigging
• With a rope you can get anything you
need into the roof very quickly
• Keep it tidy!
• Make sure you can always let go of the
rope if it gets caught
• Pulleys make life easier
L2A WaH Training (November 12)
Rigging Tips
• Baskets are most common – we will do some
later
