OSHA: What Do You Know About Focus Four Hazards? Trivia Quiz

Having 3 points of contact when accessing and egressing equipment is considered the best practice. This means that at all times, there should be three body parts (such as two feet and one hand) in contact with the equipment or structure to ensure stability and prevent falls. By maintaining three points of contact, individuals can minimize the risk of accidents and injuries while performing tasks on equipment or when entering and exiting it.

To prevent accidents or damage, it is necessary to block stacks of pipe to prevent them from rolling or moving. This is because pipes can be heavy and unstable, and if they are not properly secured, they can easily shift or fall, causing injuries or property damage. Blocking the stacks ensures stability and reduces the risk of accidents, making it a necessary safety measure.

The statement "Focus Four plus one accounts for 80% of workplace fatalities" is true. The "Focus Four" refers to the four leading causes of workplace fatalities, which are falls, electrocutions, struck by object, and caught in/between. These four causes, along with the addition of "plus one" which includes other causes such as vehicle accidents and exposure to hazardous substances, make up a significant majority (80%) of workplace fatalities. This emphasizes the importance of addressing and prioritizing these specific hazards in order to reduce the number of workplace fatalities.

Soil stability can be affected by various conditions. The type of soil plays a crucial role in determining its stability. Different soil types have different properties and characteristics that can affect their stability. Water content is another important factor that can impact soil stability. Excess water can weaken the soil structure and cause it to become unstable. Vibrations, such as those caused by earthquakes or construction activities, can also affect soil stability. These vibrations can cause the soil particles to rearrange, leading to potential instability. Therefore, all of the mentioned conditions - soil type, water content, and vibrations - can affect soil stability.

Extension cords that are torn and have exposed wires are not acceptable on a job site. This is because exposed wires can lead to electrical hazards such as shocks and fires. It is important to use extension cords that are in good condition and free from any damage to ensure safety on a job site.

The statement is false because regardless of how experienced or skilled an operator may be, wearing a seat belt is necessary for their safety. Accidents can happen unexpectedly, and wearing a seat belt significantly reduces the risk of injury or fatality in the event of a collision or sudden stop. It is important for everyone, regardless of their experience, to prioritize their safety by wearing a seat belt at all times while operating a vehicle.

The correct answer is "All of the above" because all three options - struck-by, caught-in-between, and soft tissue injury - are considered as Focus Four Plus One Hazards. These hazards are the most common causes of fatalities and serious injuries in the construction industry. Struck-by hazards refer to incidents where a worker is hit by a moving object, caught-in-between hazards involve being caught or crushed between objects, and soft tissue injuries include sprains, strains, and other musculoskeletal injuries. Therefore, all three options fall under the category of Focus Four Plus One Hazards.

A back-up alarm should be working at all times to help prevent struck-by accidents. This alarm is designed to emit a loud sound when a vehicle is moving in reverse, alerting nearby pedestrians and workers to the potential danger. By consistently functioning, the back-up alarm serves as a warning signal and helps to increase awareness and prevent accidents in situations where visibility may be limited.

Fall protection is required at a height of 6 feet or higher. This is because falls from this height or higher can cause serious injuries or even fatalities. To ensure safety, fall protection measures such as guardrails, safety nets, or personal fall arrest systems should be implemented when working at heights of 6 feet or more.

The "Focus Four" hazards are the leading causes of worker deaths on construction sites, accounting for a significant portion of fatalities. These hazards include falls from heights, being struck by objects, getting caught in or between objects or equipment, and electrocution. By identifying and addressing these hazards, construction companies can significantly improve worker safety and reduce the risk of accidents.

The protection required for an excavation is needed at a depth of 5 feet. This is because excavations that are deeper than 5 feet are at risk of cave-ins and other hazards. Therefore, safety measures such as shoring, sloping, or shielding must be implemented to ensure the protection of workers and prevent accidents or injuries. The terms "5 foot" and "5 ft" are alternative ways of expressing the same depth measurement.

Soft tissue injuries are the number one injury type in highway construction. These injuries refer to damage to muscles, tendons, ligaments, and other soft tissues in the body. In highway construction, workers are often involved in physically demanding tasks such as lifting heavy objects, operating machinery, and repetitive motions, which can lead to strains, sprains, and other soft tissue injuries. These injuries can cause pain, swelling, limited range of motion, and can significantly impact a worker's ability to perform their job. Therefore, it is crucial to prioritize safety measures and training to prevent these types of injuries in highway construction.

There are three different types of controls for mitigating a hazard. This means that there are three different ways to reduce or eliminate the risk associated with a hazard. These controls can include engineering controls, administrative controls, and personal protective equipment. Engineering controls involve modifying the physical environment to prevent or minimize exposure to the hazard. Administrative controls involve implementing policies, procedures, and training to reduce the risk. Personal protective equipment includes items such as gloves, masks, and goggles that are worn to protect individuals from the hazard.
