Exposure management strategy
An exposure management strategy plays a vital role in the management of any kind of
loss exposure or risk at site. Basically, it is a key part of the risk management life-cycle which
can be developed by company after assessing the risks and identify the major causes of it. The
present study will be based on CPB contractors which is one of the largest construction company
in Australia delivering the rail, defence, tunnelling, road and building projects. The study will
develop and design an exposure management strategy for diesel particulate matter (DPM).
Further the report will cover an occupational assessment strategy, toxicology, hygiene standard
setting.
1. Occupational assessment strategy
a. Sources of Occupational Exposure
there are many different sources of occupational exposure which must be taken into
consideration. It can occur through contact of the mouth, eye, nose, skin with a blood of patient.
In addition, it can also occur through cuts on skin through sharp instruments contaminated with
an infected person's blood, needle sticks which used before on infected person and other
infectious materials.
B. Routes of Entry
Blood-borne pathogen and chemicals enter the body awareness is very important topic
which must be discussed at workplace especially on construction sites. By understanding this
safety related topic employees and workers could potentially encounter any blood-borne
pathogen.
There are various ways that blood borne pathogen can be transmitted which can infect the other
person too. In the construction site or workplace the very common cause of transmission is when
an infected patient's blood enters another person's bloodstream. The main route of this
transmission is an open wound through which person get infected badly which can turn into
serious health condition (Liu and et.al. 2021).
Apart from this there are other ways too or main routes of entry:
 Penetration of skin- in the healthcare settings, skin is the main route of transmission
through which infection spread easily which can infect person body. Skin penetration is a
common hazard which can be occurred through the use of sharp objects or instruments
such as broken glass, razors, blades, needles and used injections.
