A Safety Quiz On The Types Of Hazards!

Explanation
This answer is correct because hazards can be actual and/or behavioral, potential, physical, and biological. Hazards can encompass a wide range of activities, arrangements, circumstances, events, or occurrences that have the potential to cause harm. These hazards can be present in various forms, including physical hazards (such as machinery or hazardous substances), biological hazards (such as infectious diseases), and potential hazards (such as potential fire hazards or potential risks in a workplace). Therefore, all of the options mentioned in the answer are valid examples of hazards.

Explanation
The statement is true because a hazard refers to any object, situation, or activity that has the potential to cause harm or injury. It can include physical hazards like sharp objects or slippery surfaces, chemical hazards like toxic substances, biological hazards like bacteria or viruses, and even psychological hazards like stress or bullying. By recognizing hazards, we can take appropriate measures to prevent accidents and ensure safety in various environments such as workplaces, homes, or public spaces.

Explanation
All of the options listed in the question are potential hazards in the workplace. Working when very tired or under the influence of drugs or alcohol can impair judgment and coordination, increasing the risk of accidents. Working on a wet floor can lead to slips and falls. Breathing in toxic fumes can cause respiratory problems and other health issues. Manual tasks that strain the body can result in musculoskeletal injuries. Therefore, all of these options pose potential hazards in the workplace.

Explanation
Falls are the leading cause of death on construction sites. This is because construction workers often work at heights, such as on scaffolding or ladders, which increases the risk of falling. Additionally, construction sites can be cluttered with equipment and debris, making it easier for workers to trip and fall. Falls can result in severe injuries or even fatalities, making it crucial for construction workers to follow safety protocols and use proper protective equipment to prevent such accidents.

Explanation
Carcinogenicity refers to the ability of a substance to cause cancer. It is a chemical-related health hazard because exposure to carcinogens can increase the risk of developing cancer. Reactivity, corrosivity, and toxicity are all chemical-related health hazards as well. Reactivity refers to the ability of a substance to undergo a chemical reaction, which can result in explosions or release of toxic gases. Corrosivity refers to the ability of a substance to cause damage to living tissue or materials. Toxicity refers to the ability of a substance to cause harm or injury to living organisms.

Explanation
The word "Danger" would be used to convey the most severe type of hazard. It indicates a high level of risk and potential harm or danger to individuals. Unlike "Warning" or "Caution", which suggest a lesser degree of risk, "Danger" signifies an immediate threat that requires immediate attention and caution. "Notice" does not convey the same level of urgency and severity as "Danger".

Explanation
Ammonia becomes an immediate danger to your life and health when it is present at or above 300 ppm. At this concentration, ammonia can cause severe irritation and damage to the respiratory system, eyes, and skin. It can also lead to difficulty breathing, coughing, chest pain, and even lung damage. Exposure to high levels of ammonia can be life-threatening and immediate medical attention is necessary.

Explanation
The statement is false because when working near a flammable substance, it is recommended to use non-sparking tools made of materials such as brass, bronze, or aluminum-bronze. Iron or steel hand tools can create sparks and increase the risk of igniting the flammable substance.
