to make provisions for specially constructed well drained and durable temporary
roadways and hard standings. Consideration should be given to the construction of
permanent roadways and hard standings prior to erection.
4. Storage Areas

undertaken, additional areas may needed with facilities similar to those of storage
areas
DELIVER, UNLOADING & STACKING
SAFETY MANUAL
MESSA
SDN BHD
1. Planning
1.1. The delivery of materials to site should be planned:1.1.1. To coincide with the availability of sufficient numbers of personnel and suitable
cranes to ensure safe unloading.
1.1.2.
So that arrangements are made to safeguard the public if access to site is
impracticable and delivery vehicles have to be unloaded from the highway.
1.1.3. To allow for components to be erected directly from the delivery lorry, where
appropriate, and particularly if storage space is limited.
1.1.4. To cater for possible need to store extra material on site in a buffer store.
1.2. When organizing the stacking area account should be taken of site suitability, including
ground stability.
2
UNLOADING
2.1 Special care should be taken when unloading delivery vehicles to ensure that:2.1.1
They are stable at all times.
2.1.2
Adequate lighting is available especially deliveries may made when there
is insufficient daylight.
2.1.3
Lifting or slinging points are present and correctly marked, particularly for
unusually shaped components, heavy components or sub-assemblies
special lifting attachments or brackets may be required.
2.1.4
The weights are clearly marked on all member bundles of components and
sub-assemblies of one ton or over.
2.1.5
Unwanted rotational movement of long components or sub-assemblies is
prevented by using hand lines fixed near the ends of the load.
3
STACKING AND RESTACKING
SAFETY MANUAL
MESSA
SDN BHD
3.1 Any stack of materials, whatever its size, should be made in such a way that it can be
restacked safely. Matters which should be taken into account when stacking or
restacking components include:3.1.1
Stacking in a way which will ensure that there is no risk of collapse,
sliding or distortion.
3.1.2
Enhancing stability of stack by ensuring the supply and use of adequate
numbers of timber packing pieces battens and wedges, which should be of
suitable size and strength and positioned in lines vertically throughout the
stack.
3.1.3
The safety personnel on the stack by ensuring that if access at height is
required (e.g. to fix or remove lifting slings) operatives are provided with
a safe means of access and safe places of work.
3.1.4
Avoiding injury due to trapping when handling. Having considered the
general requirement for safe stacking and restacking, there may be
advantages in using specialized devices such as mobile or transportable
storage rage.
LIFTING & HANDLING
1
PLANNING
1.1 Safety during lifting and handling requires careful consideration of all aspects of
methods and system to be used.
2
Use of Cranes and Derricks
2.1 Factors specially relating to use of cranes and which should be coordinated include:
2.1.1
Organizing the appropriate number and type of cranes.
2.1.2
Confirming that the designated sitting positions for cranes can be achieved
with suitable hard standings provided.
SAFETY MANUAL
MESSA
SDN BHD
2.1.3
Checking for the presence of hazards or developments which may have
altered the site since the original plans were made.
2.1.4
Appointing a competent person to supervise the complete lifting operation
particularly when tandem or multi-lifts are used.
3
Lifting and Slinging
3.1 When lifting:3.1.1
The total weight to be lifted should be established and should include
lifting gear such as slings, lifting beams, crane blocks and rope falls as
appropriate.
3.1.2
The use of special devices such as titling shoes for columns and lifting
frames for sub-assemblies should be considered.
3.1.3
All lifting frames and beams should be designed, tested (when applicable)
and should display prominently the safe working load and the self weight.
3.2 When slinging, it is particularly important that use is made of:3.2.1
Lifting aids such as lifting beams to prevent overloading the slings and to
provide support for slender flexible assemblies such as roof trusses.
3.2.2
Two-leg slings wherever possible as they provide greater stability of the
load, although care should be taken to ensure that the included angle is
within the safe range.
3.2.3
Packing to help avoid damaging the slings and prevent the load slipping.
3.3 Other factor to be considered include:3.3.1
Preventing unwanted rotational movement of loads, particularly long loads
by using hand lines fixed near the ends of load.
3.3.2
Avoiding shock loading on slings by lifting and lowering slowly at all
times.
3.3.3
Using timber battens on which to land loads so that the sling can be
removed easily and is not damaged by crushing.

SAFETY MANUAL
WORKING PLACES AND ACCESS
1
Use of Safety Harness / Belts
1.1 Although the provision of a safe place of a safe place of work should always be the
first consideration, there may be occasions where such a high standard is not
practicable and there is still a risk of the erector falling (while erectors are landing
and connecting section while straddling beams).Erectors will then need to attach
themselves to the structure etc, in order to ensure their safety. Erector should
therefore be equipped themselves with safety harness / belts at ground level until they
are required to be used for particular operations. Safety harness equipment must fit
correctly and be kept in good order and should be regularly inspected by the user and
at intervals by competent person. Generally, the use of safety harnesses, as opposed to
belts, is preferable as a longer safety lanyard can be used.
1.2 The lanyard of the harness / belt should be attached to the structure or other fixing
point, preferably as possible above the working position to limit the height of any fall.
Methods of attachment include.
1.3 Looping the lanyard around a structural member, and fastening the hook back onto
the lanyard. The use of such a ‘choke hitch’ is dependent on the overall size of the
frame member encompassed by the loop of the member, which may be small enough
to cut the lanyard if a fall should occur. In such cases the lanyard can be increased in
thickness or be sleeved to prevent this cutting action.
SAFETY MANUAL
MESSA
SDN BHD
1.4 Where frame members are too big to allow lanyards to be chocked around, a wire
rope (minimum diameter 16mm) can be secured around the member (preferably at
ground level prior to erection) and the lanyard then attached to the wire rope itself.
1.5 For some activities (e.g. erection of masts and towers) inertia reels long lines may be
used. Anchors will need to be provided to take any loads that may occur, and the
layout of lines and the position of the inertia reel cable box will need to be so
positioned that other activities are not impeded. The use of equipment that runs along
the lines is depended on the length, type and layout of the line.
2
Use of Safety Nets
2.1 In certain instances the use of safety nets may be an effective to the use of safety
harnesses etc. It should be remembered, though, that the erection and dismantling of
safety nets could be potentially hazardous operation in itself. The work must therefore
be carefully planned and supervised and only undertaken by properly trained
operatives.
2.2 Nets should be fitted as close to the working surface as possible, but in any case must
not be lower than 6m below the work. The initial sag should be about ¼ to1/5 of the
span of the net and because the net will displaced vertically should a fall occur, there
must be a further clearance below the initial sag of 2m.
2.3 A downward fall is resisted at the net perimeter by both horizontal and vertical forces:
members supporting nets must therefore be able to support these forces adequately in
each direction. Nets must be inspected after any fall and at regular intervals.
