What surrounds your Program




      P bar Y Safety Consultants Alberta Canada
Erection of Structures

• Can be both difficult and dangerous

• Many fatal and serious accidents occur

• Principal cause - falls from height

• Other causes include:
  – structural instability during erection
  – handling, lifting and transporting materials
                      P bar Y Safety Consultants Alberta Canada
Safe Place of Work

• Every place of work shall be kept safe.

• Safe access and egress to/from the workplace.

• Prevent persons gaining access to an unsafe place.

• People making places safe must consider their own safety.



                      P bar Y Safety Consultants Alberta Canada
Falling Objects

• Precautions must be taken to prevent danger from falling
  materials or objects.

• Toe boards, brickguards and working platforms

• Debris nets, fans or exclusion zones

• Materials and equipment to be stored safely to prevent
  collapse, overturning or unintentional movement.

                     P bar Y Safety Consultants Alberta Canada
Stability of Structures

Stability of Structures
• The stability of any structure (temporary or permanent)
  should not be adversely affected by construction work.

• Structures, including scaffolding, must not be overloaded
  and loads must be evenly distributed.

• The erection and dismantling of temporary works must be
  supervised by a competent person.

                     P bar Y Safety Consultants Alberta Canada
Temporary Works Co-ordinator

Principal Activities:
• Co-ordinate all falsework activities
• Ensure the various responsibilities have been allocated and
  accepted
• Ensure that a design brief has been established with full
  consultation, is adequate, and is in accordance with the
  actual situation on site
• Ensure that a satisfactory falsework design is carried out
• Ensure that the design is independently checked for:
   – concept
   – structural adequacy
   – compliance withPthe brief Alberta Canada
                       bar Y Safety Consultants
Temporary Works Co-ordinator

Principal Activities:
• Where appropriate, make the design available to other
  interested parties.
• Register or record the drawings, calculations and other
  documents relevant to the final design
• Ensure that those responsible for on-site supervision
  receive full details of the design, including any specified
  limitations.
• Ensure checks are carried out at appropriate stages
  covering the more critical factors
• Ensure that any proposed changes in materials or
  construction are checked against the original design
                      P bar Y Safety Consultants Alberta Canada
Temporary Works Co-ordinator

Principal Activities:
• Ensure that any agreed changes, or correction of faults, are
  correctly carried out.
• Ensure that, during use, all appropriate maintenance is
  carried out.
• After final check, issue formal permission to load if this
  check proves satisfactory
• When it has been confirmed that the permanent structure
  has attained adequate strength, issue formal permission to
  dismantle the falsework
                     P bar Y Safety Consultants Alberta Canada
Erection of Structures

Safety requirements would include:
• stability at all stages of erection of the structure
• the effect of the erection sequence on stability
• realistic assessment of loadings at all stages of
  construction
• provision of safe access and working space
• ease of connecting components
• safe handling, lifting, storing, stacking and transportation
  of components

                      P bar Y Safety Consultants Alberta Canada
Site Hazards and Limitations

• Overhead and electric power lines
• Buried services - gas, water, electricity etc.
• Restricted access - road alignment etc.
• Restricted space for erection, manoeuvring, storage or
  onsite fabrication
• Low ground bearing capacity - made up ground or existing
  underground structures




                    P bar Y Safety Consultants Alberta Canada
Site Hazards and Limitations

• Close proximity of other buildings, roads, railways, canals,
  rivers etc.
• Proximity of general public to the site
• Activities of other contractors - restrict access - display
  signs - inform in writing - co-ordination
• Gases, chemical, fluids or dust from processes on or near
  the site




                      P bar Y Safety Consultants Alberta Canada
Material Storage

•   Clear of obstructions, reasonably level
•   Ground capable of taking the loads to be applied
•   Sited away from hazards e.g. overhead cables
•   Clear access to and through the store area
•   Lighting if required




                       P bar Y Safety Consultants Alberta Canada
Material Stacking

• Materials stacked in safe manner, that allows de-stacking
  safely
• Methods of stacking with no risk of collapse or sliding
• Adequate supply of timbers, and wedges
• Sufficient space left to enable safe slinging
• Kept off the ground to prevent unintentional mud/stones
  being lifted off the ground

Weather Conditions

• Rain, ice or snow can turn a secure footing into a skating
  rink - inspect before work commences
• Beware of hypothermia
• Sudden gust of wind could lead to loss of balance - avoid
  fixing roof sheets and felt in windy weather
• At the end of the working day, ensure that loose materials
  are not left on the roof




                     P bar Y Safety Consultants Alberta Canada
Weather Conditions

• Use an anemometer to measure wind speed




                P bar Y Safety Consultants Alberta Canada
Weather Conditions

• Consider the effects of very hot weather
  – heat exhaustion / stroke
  – sun burn / skin cancer
  – handling hot metal components




                     P bar Y Safety Consultants Alberta Canada

All trades should be appropriately trained:
    – formworkers
    – sheeters and cladders
    – post tensioners
    – steelfixers
    – construction operatives




                      P bar Y Safety Consultants Alberta Canada
