The following is Written notes on Whiteboard
http://www.filefactory.com/file/1snmwfyogezr/Class%20Lesson%20Wk%202.zip
The followings are key points
Duty of
Care
Duty of care requires everything
'reasonably practicable' to be done to protect the health and safety of others.
This duty is placed on all employers, their employees, and any others who have
an influence on the hazards in a workplace including contractors and those who design, manufacture, import,
supply or install plant, equipment or materials used in the workplace. Engineers, therefore, have a duty of care. Duty of care places into a legal form what is
a natural moral duty to anticipate possible causes of injury and to do
everything practicable to remove or minimise these hazards
AS3000
Q4 AS/NZS 3000 is divided into two parts. Part 1 sets the safety and performance standards to which an electrical installation shall comply, whereas Part 2 provides installation practices that achieve certainty of compliance with the standards set out in Part 1
Risk Assessment
The Work Health and Safety (WHS) Act and Regulations require persons who have a duty to ensure health and safety to 'manage risks' by eliminating health and safety risks so far as is reasonably practicable, and if it is not reasonably practicable to do so, to minimise those risks so far as is reasonably practicable.
See risk assessment matrix in ENPRA101A Week 2 Ch 2 Intro to the regulatory system Student Workbook Page 13
Code
of Ethics
A code of
ethics is a set of guidelines designed to set out acceptable behaviours for
members of a particular group, association, or profession
Assignments
The following assignments have been given
Assignment 1-Essay (Power Generation & Distribution)- Due week 3
