Work Health and Safety (WHS)
What does the Work Health and Safety Act 2011 aim to do?
To protect workers and other people by eliminating or minimising workplace health and safety risks, while providing a balanced and nationally consistent framework.
What is the difference between a hazard and a risk?
A source or situation with the potential to cause harm, compared with the likelihood and possible severity of that harm occurring.
What type of safety sign is a yellow triangle with a black symbol?
A yellow triangle with a black border and symbol that alerts people to a hazard or possible danger.
What is sound reinforcement?
The use of microphones, mixers, amplifiers and loudspeakers to make live sound louder, clearer and appropriately distributed to an audience.
What is the key difference between active and passive speakers?
One has a power amplifier built into the enclosure, while the other requires an external amplifier.
Who is considered a Person Conducting a Business or Undertaking (PCBU)?
A person or legal entity that operates a business or undertaking, such as a company, sole trader, partnership or organisation.
Which of the following is a physical hazard in the entertainment industry?
Unsecured electrical leads or audio cables across a walkway, creating a trip hazard.
When working at heights, at what height must a harness be worn?
There is no single automatic height. Fall risks must be controlled at any height, and a harness is used when the risk assessment and safe system of work require it and higher-level controls are not reasonably practicable.
Which of the following is not a stage of sound reinforcement?
Mastering a studio recording for commercial release.
Which type of microphone is most commonly used for live performances due to its durability?
This rugged microphone type tolerates high sound-pressure levels and is commonly used for live vocals and instruments.
What is the primary duty of care of a PCBU?
To ensure, so far as is reasonably practicable, the health and safety of workers and other people who may be affected by the work.
What is the purpose of a risk assessment?
To evaluate how likely harm is, how serious it could be, and what action is needed to eliminate or minimise the risk.
Which work practice helps prevent manual handling injuries?
Planning the lift, keeping the load close, avoiding twisting, and using a mechanical aid or team lift when needed.
Which signal level requires a preamplifier to boost it?
This low-level signal produced by a microphone normally needs a preamplifier before further processing or mixing.
What is the difference between large and small diaphragm condenser microphones?
The larger type is often more sensitive and produces a fuller sound, while the smaller type commonly offers faster transient response and more consistent, accurate pickup.
What must workers do to comply with WHS?
Take reasonable care of their own and others' health and safety, follow reasonable safety instructions, and cooperate with notified WHS policies and procedures.
What is the Hierarchy of Controls used for?
A ranked system for selecting risk controls from the highest level of protection and reliability to the lowest.
Why should electrical cables be tested and tagged?
To identify damage or electrical faults and confirm that portable electrical equipment is safe for continued use.
What is the main difference between an analogue and digital mixing console?
One processes continuously varying electrical signals, while the other converts signals to digital data and offers software-based processing, routing and recall.
Which microphone is highly directional and commonly used in film and broadcasting?
A highly directional microphone with a long interference tube, widely used to capture dialogue in film and broadcasting.
Which of the following is not a worker’s right under WHS laws?
Ignoring reasonable safety instructions or choosing not to follow workplace safety procedures.
Which of the following is the most effective risk control method in the Hierarchy of Controls?
Removing the hazard completely so that exposure to the risk no longer exists.
What is Tinnitus?
The perception of ringing, buzzing or another sound when no external sound is present; it can be associated with hearing damage from excessive noise exposure.
What does a crossover do in an audio system?
It divides an audio signal into frequency bands and sends each band to the speaker or driver designed to reproduce it.
What is the primary use of a lavalier (lapel) microphone?
Hands-free, close-miked speech for presenters, actors and interview subjects using a small microphone clipped to clothing.
