Hari ini seorang kontraktor aircond maut terjatuh dari tingkat 3 sebuah rumah atau pangsapuri semasa serbis atau memasang air cond baru.Mangsa mengalami kecederaan parah di kepala dan patah dan insiden ini sedang di siasat.
Tentu semua penduduk bandar pernah memanggil kontraktor aircond untuk serbis ataupun mengganti aircond yang rosak.Macammana mereka berkerja maksudnya aspek keselamatan yang mereka terapkan.Bukan hendak menyalahkan mangsa seorang tetapi 95 % daripadanya mengabaikan aspek2 keselamatan.
Apabila bekerja di tempat tinggi,tiada helmet dan tiada tali pinggang keselamatan atau tali untuk mengikat diri mereka untuk mengelakan mereka dari jatuh kebawah.Mereka membawa barang2 dan peralatan yang berat dan semasa bekerja seperti menggerudi,gegaran dari mesin tersebut boleh membuat kan diri mereka tergelincir ke bawah.
Apakah langkah2 yang patut tuan rumah praktikan sebelum memanggil kontraktor memasang aircon atau membuat servis.Telah ada garispanduan yang baik apabila bekerja di tempat yang tinggi tidak kira ape jenis pekerjaan.Baik pembinaan.elektikal ataupu mekanikal ataupun apa2 pekerjaan di tempat yang tinggi,
Antara garis panduan adalah :
15.5.2.8 Working at Height Using Portable Step Ladders
Portable ladders are commonly used in construction site for its expediency and
reliability, hazards of falling from ladder could result in serious injury, therefore the
following safe work procedure to adhere by all workers to prevent untoward incidents.
a) The user to ensure that ladder is fitted with non-slip feet.
b) Ensure that the ladder is placed on a firm and level footing.
c) Where the ladder is being used to gain access to a platform or roof, the ladder
is to extend beyond the platform or roof level by at least 1 metre.
d) Do not work alone with ladders always work with a buddy to hold the ladder for
stability.
e) When working on a ladder above 2m from the ground level, the user shall wear
an approved safety harness and be coupled to a fixed structure or the secured
ladder via a suitable lanyard.
f) All materials are to be raised and lowered with a rope. Small items may be
placed in a safety harness bolt bag or tool frog to allow user to climb and
descend the ladder using both hands.
g) All tools to be secured effectively to prevent dropping accidentally.
h) Do face the ladder when ascending or descending, never turn away from the
ladder.
i) Do barricade around ladders to protect them from being bumped.
j) Do not use the top three rungs of a ladder.
k) Do not tie or fasten ladders together to provide longer.
l) Do not “walk” or rock a ladder side to side to move it into place.
m) Do maintain three point contacts all the times (hands & feet).
n) Avoid work that imposes a side loading such as side-on drilling through solid
materials, by having the steps facing the work activity. Where side-on loading
cannot be avoided should prevent the steps from tipping over, by tying the steps
to a suitable point.
o) Only wooden or fibreglass ladders are to be used in electrical annexes, switch
rooms or near electrical cabling or circuitry.
h) Ladder inspection :
All ladders must be inspected periodically and after any occurrence, that could
affect their safe use or to carryout inspection whenever a ladder falls over and
hits the ground. Always inspect the followings:-
i. The “feet” or cleats of a ladder for damage.
ii. The back of stepladders for stability.
iii. Hooks and locks on straight ladders with extensions.
iv. The rungs of the ladder for bends or breaks.
v. The locking mechanism on a step ladder.
The thumb rule to determine the correct leaning angle of a straight ladder is a
worker standing in front of a ladder should be able to grab a rung with both arms
extended forward at shoulder level without bending forward.
15.5.2.9 Working on Roof (refer Chapter 20 Roofing Work)
If workers are working on roofs with unprotected sides and edges 3 meters or more
above ground levels, they shall be protected from falling by guardrail systems, safety

guard-rail system, warning line system and safety net system, warning line system and
personal fall arrest system, or warning line system.
a) Warning line system
i. Employees performing roofing work between a roof edge and a warning
line must be protected by guardrails or safety nets erected around all open
sides of the roof work area no less than 3m from the roof edge.
ii. Points of access and material handling areas must be connected to the
work area by an access path formed by two warning lines close
access/offset when not in use.
iii. Warning lines must consist of ropes, wires, or chains, and flagged every
2m with high-visibility material/warning tapes rigged and supported that its
lowest point (including sag) is no less than 690mm and its highest point is
no more than 1.2m.
iv. Stanchions must be capable of resisting at least 10kg of force.
v. Warning line must have a minimum tensile strength of 225kg.
vi. Workers are not allowed to work between the roof edge and warning line
unless performing roofing work.
vii. Must not be use as fall protection on slopes greater than 2:12.
b) Slide guide system
i. Installation of the system must be under direct supervision of competent
person.
ii. Cannot used on roofs with ground/eave height of 25 ft. or more.
iii. Cannot used as fall protection on roofs with a slope less than 3:12 nor greater
than 8:12.
iv. Roofs that with slopes greater than or equal to 3:12 to and including 6:12.
Minimum of one slide guard placed below the work area and not closer than
6” from the eave.
v. Roofs that with slopes greater than 6:12 to 8:12. Multiple slide guards must be
used with spaced 8’ apart, vertically and lower slide guard must be placed
no closer than 6” from eave.
vi. Lowest slide guard must be 90 degrees to the roof surface.
vii. Upper slide guards cannot be less than 60 degrees to the roof surface.
