CLASS ACTIVITIES - Student
CPCCCM2012 - Work safely at heights
Question 1: According to Safe Work Australia’s 2018, what are the areas that need special attention
while working at heights?
The areas that need special attention are:
close to an exposed edge that isn't covered, like the edges of leading formwork or unfinished
stairwells.
utilizing tools to perform tasks at an elevated height, such as portable ladders or elevating
work platforms (EWPs)
on any building or equipment that is being built, installed, dismantled, inspected, tested,
cleaned, or repaired.
on or near a delicate surface, such as skylights, rusted metal roofs, cement sheeting roofs, or
fiberglass sheeting roofs.
close to a hole, shaft, or pit that a worker could fall into, such as trenches;
on a sloping or slippery surface where it is difficult for people to maintain their balance; and
on an unstable surface, such as one where there is a chance of the ground collapsing.
Question 2: Explain the steps to determine job priorities and sequence job tasks in consultation with
a relevant person on site.
Compile job instructions:
The qualities required to finish a specific job or task are known as work specifications and
strategies. A guidebook that contains designs, specifications, standards for quality, operational information,
and accuracy checks on the work might be necessary. Prioritize tasks and arrange them in order of completion:
Worksite, environmental, and organizational safety strategies must be followed at all times.
Procedures ensure that the work is done safely, preventing damage to tools and placing people in
risky situations. They also aid in making sure that the tasks are finished in the proper sequence
and don't interfere with or obstruct other tasks being done on the site.

Question 3: Write down the various factors to consider while preparing SWMS for a specific task.
The various factors to consider while preparing SWMS for a specific task are:
Address about high-risk construction activity like risks, hazards and control methods and
communicate with appropriate construction workers.
A column labelled "High-Risk Construction Work" should exist, providing an overview of
the high-risk construction projects that need to be performed.
A column of hazards and risks.
Conditions like work environment that influence how the construction work with high-risk
will be done, for example: construction plan, working environment, safe work methods
and pant to be used
A column of “control measures” with hierarchy of controls.
Question 4: Explain various control measures to avoid any risk at workplace.
The control measures to avoid any risk at workplace are:
Use PPE kits – this preventive measure is of the bottom order and applied when other
measures are not effective. It does not lower the hazard.
Use signs – there are different signs available according to need. These are prohibition signs,
mandatory, restriction, hazard, emergency, fire signs
Use fall restraint device - it protects the person from fall. Guard rail and barriers are installed
for more protection.
Use a fall arrest system – it protects the worker by avoiding the fall before striking the ground
after he fell.
Use administrative controls – this is effective when other measures are unsuccessful. It
comprises numerous design methods and actions to minimise hazards.

Question 7: How can you prevent the risk of fall from height?
The risk of fall from height can be prevented by using following measures:
Using fall prevention devices – the fall prevention devices such as guard rails and scaffolding
can be used to reduce the risk of fall due to unbalanced and fragile surfaces.
Using different types of work positioning systems – work positioning system such as a rope
access system can also be used. Question 8: What is meant by Elevated work platforms (EWPs)? List its types, characteristics, uses
and limitations.
Elevated work platform is a mobile machine (device) featuring at least a work platform with
controls, an extending frame, and a chassis is meant to transfer people, tools, and materials to
working locations.

Question 9: What are the safety manuals and instructions for checking plant, tools and equipment?
The safety manuals and instructions for checking plant, tools and equipment are:
Operation manuals – the detailed document that helps workers operating well by providing
information of equipment and its parts. Each tool or equipment has a ‘Operation manual’
which explains their working. These are essential guidelines which guarantees the safe usage
of the tools or equipment.
Manufacturer specifications - this provides technical data of tools and equipment which guard
the workers form the hazards related to a tool or equipment.
Safety signs and load charts for plants: these are available in several layouts in order to
protect workers from possible hazard resulting from defective tools, equipment and plants.
Load chart is an illustration and diagram that shows how much authorised work a tool, plant,
or equipment would be able to carry out.
Question 10: What is meant by signs? List the correct titles for these signs.
Signs are essential components of any construction site since they are vital instruments for
guaranteeing security and safety. These are extremely important for directing workers,
communicating important information, and warning guests of potential dangers. They can be in
pictures, written or both. The various forms of signs are:
Prohibition signs (don’t do)
Restriction signs (limiting)
Hazard signs (warning signs)
Mandatory signs (must do)
Fire signs
Emergency signs (medical, exit etc.)

Task 2
The transfer of heat from one fluid to another is an essential component of all chemical processes.
Whether it is to cool down a chemical after it has been formed during an exothermic reaction, or
to heat components before starting a reaction to make a final product, the thermal processing
operation is core to the chemical process. It is essential that heat transfer systems for chemical
processes are designed to maximize efficiency. Because the heat transfer step in many chemical
processes is energy intensive, a failure to focus on efficiency can drive up costs unnecessarily.
Task expected from student:
a) Compare the basic design between the classifications of heat exchanger equipment's (Any
three HE equipment's).
b) Summarize the merits, demerits, limitations and applications of heat exchanger equipment's
with neat sketch.
