In the realm of machinery safety, the concept of perceived risk plays a pivotal role in
shaping attitudes towards safety practices and compliance with regulations. As a
machinery safety consultant, it’s essential to recognize how individuals perceive risks
associated with different types of machinery. A prime example of this can be observed
in the contrasting perceptions of petrol and electric chainsaws.

Petrol Chainsaw: The Loud and Obvious Hazard
The distinct roar of a petrol chainsaw commands attention and instils a sense of
caution in those in proximity. Its loudness and appearance evoke a clear understanding of
the possible risk it presents. People tend to be more alert and conscientious when
approaching or using a petrol chainsaw, recognizing the inherent risks involved. The
audible cues of its operation serve as constant reminders of the potential hazards
present, even from a distance.
Additionally, the visible vibration from the engine of a petrol chainsaw reinforces the
awareness of its operational state and the potential for injury. This visibility makes it
easier for individuals to gauge the level of risk and take appropriate safety measures,
such as wearing personal protective equipment (PPE) and maintaining a safe distance.
Electric Chainsaw: Silent but Deceptive
In stark contrast, the electric chainsaw operates with a deceptive silence when the
chain is not in motion and is still quiet when the chain is in motion. This lack of audible
cues can create a false sense of security, as individuals may underrate the
potential hazards associated with its use. Unlike the petrol chainsaw, the presence of a
potential hazard is not immediately apparent to those nearby unless they witness the
machinery in operation.
Furthermore, distinguishing between a mains-powered electric chainsaw and a
battery-powered one adds another layer of complexity to risk perception. With
battery-powered models, the chainsaw can be easily started without any visible signs,
as the battery remains attached. This ambiguity increases the likelihood of accidents,
especially in environments where multiple chainsaws are present, and their power
sources are not clearly indicated.

Accessibility and Ease of Operation
Another factor influencing perceived risk is the accessibility and ease of operation of
electric chainsaws compared to petrol ones. Electric chainsaws are often perceived as
more user-friendly, making them accessible to individuals with little to no experience in
using such machinery. This accessibility, coupled with the deceptive silence of their
operation, can lead to complacency and a lack of vigilance regarding safety protocols.
Moreover, the prevalence of toy chainsaws resembling electric models further blurs the
lines between real and perceived risks, especially for children who may not fully grasp
the potential dangers associated with these tools.
Conclusion: Balancing Perception and Reality
In the realm of machinery safety, understanding and addressing perceived risks are
essential for promoting a culture of safety and compliance. While petrol and electric
chainsaws serve similar purposes, their distinct characteristics significantly influence
how individuals perceive and respond to potential hazards.
As machinery safety consultants, it’s crucial to educate stakeholders about the
importance of recognising and mitigating risks associated with different types of
machinery. By raising awareness and promoting proactive safety measures, we can
work towards minimizing accidents and ensuring the well-being of workers and the public.
