Workplace Health And Safety Questions! Trivia Quiz

Explanation
Lifting heavy objects badly is the most common cause of back injury at work. This is because when heavy objects are lifted incorrectly, it puts excessive strain on the back muscles, ligaments, and discs, leading to injuries such as muscle strains, herniated discs, or sprains. Proper lifting techniques, such as bending the knees, using the leg muscles, and keeping the back straight, are important to prevent back injuries while lifting heavy objects. Sitting on chairs and standing for too long may cause discomfort or fatigue, but they are not the primary cause of back injuries at work.

Explanation
A fire needs three elements to start and continue: a combustible substance, oxygen, and heat. The combustible substance provides the fuel for the fire, while oxygen is required for the combustion process. Heat is necessary to raise the temperature of the combustible substance to its ignition point, initiating the fire. The presence of a match, oil, or air is not essential for a fire to start and continue, making them incorrect choices.

Explanation
Water-based fire extinguishers should not be used on electrical fires because water is a conductor of electricity and can potentially cause electric shock or spread the fire. It is recommended to use a fire extinguisher specifically designed for electrical fires, such as a CO2 or dry chemical extinguisher.

Explanation
When using a computer workstation, it is important to ensure that your feet are on the ground, your arms are level, and your back is well supported. However, looking slightly down at your screen is not true. It is recommended to have your screen at eye level to maintain proper posture and reduce strain on the neck and eyes. Looking slightly down can lead to neck and shoulder discomfort.

Explanation
Overloading a plug socket can cause fire because the excessive flow of electricity can generate heat and lead to a fire hazard. It can also blow the fuses as the electrical circuit becomes overwhelmed with the excess current, causing the fuses to break and interrupt the flow of electricity. Additionally, overloading can damage your equipment as the excessive power can cause components to overheat or fail, leading to potential damage or malfunction.

Explanation
Stacking boxes above shoulder height can be unsafe as it increases the risk of accidents and injuries. When boxes are stacked too high, they become unstable and can easily topple over, potentially causing harm to individuals nearby. Additionally, lifting heavy boxes above shoulder height can strain the muscles and joints, leading to musculoskeletal injuries. To ensure a safe working environment, it is recommended to keep boxes stacked at a manageable height, below shoulder level, reducing the risk of accidents and injuries.

Explanation
In the event of a fire, it is not recommended to try to put it out first. The priority should be to ensure personal safety and evacuate the area immediately. Fires can spread rapidly and become uncontrollable, posing a significant risk to life and property. It is important to follow established fire safety protocols, such as activating fire alarms, alerting others, and using designated evacuation routes. Attempting to extinguish a fire without proper training and equipment can lead to injuries or even fatalities.

Explanation
It is important for any public building or workplace to have clearly signed exit routes for the safety and well-being of the people inside. Clear signage helps individuals quickly locate the nearest exit in case of emergencies such as fires, natural disasters, or other hazardous situations. This ensures that people can evacuate the building efficiently and reduces the risk of injuries or fatalities. Therefore, it is necessary for public buildings and workplaces to have clearly signed exit routes.

Explanation
The answer is true because when there is ice and snow outside, it is important to grit the area around a building to prevent accidents and ensure safety. Gritting involves spreading salt or sand on the ground to melt the ice and provide traction, making it easier for people to walk and reducing the risk of slips and falls. Therefore, it is necessary to grit the area to maintain a safe environment.
