Why is design so important to safety?
2Slide3
What is safety in design?
Safety in design is aimed at preventing injuries and disease by considering hazards as early as possible in the planning and design process.3Slide4
Design improvements over time

What responsibilities do you have?
Mines Safety and Inspection Act 1994, section 14(1) A person who designs, manufactures, imports or supplies any plant for use at a mine must, so far as is practicable –(a) ensure that the
design
and
construction
of the plant is such that persons who
properly install
,
maintain
or
use
the plant are not, in doing so, exposed to hazards
7Slide8
Reasonably practicable
Sacrifice in time, money and trouble

Quantum of risk severity and likelihood of eventSlide9
What are the consequences of poor design?
Risk of injury or loss of lifeEnvironmental or equipment damageLoss of incomeLow productivityHigher operating costs Higher maintenance costsReduced asset lifeHigher employment and workers’ compensation expenses

Consider
not the cost of fixing a problem in the design stage, but the cost of not
fixing
a
problem
in
the design stage!
