What is hazard?
Event that gave rise to an
accident or had potential to
lead to an accident
Source or situation (chemical or physical) with a
potential to cause harm, injury or damage to either
human, property or the environment or some
combination of these
a combination of the likelihood of an
occurrence of a hazardous event with
specified period
an event likely to occur within the
specific period or in specified circumstances
Which of the following is an example of a physical hazard?
Noise exposure
Toxic chemicals
Viruses and bacteria
Workplace stress
What is the best way to control a hazard in the workplace?
Relying on personal protective equipment (PPE)
Eliminating or reducing the hazard at the source
Increasing the number of warning signs
Conducting frequent safety training
Slips, trips, and falls are considered biological hazards.
Electrical hazards can occur due to faulty wiring or overloaded circuits.
Which example best represents the application of inherent safety?
Training employees to wear protective gear
Installing more alarms and emergency systems
Increasing the number of safety inspections
Replacing a toxic chemical with a less hazardous alternative
What is the main advantage of inherent passive safety?
It relies on external safety devices to prevent hazards
It eliminates the need for human intervention and external energy sources
It increases the complexity of the safety system
It requires frequent maintenance to remain effective
