What is the PRIMARY goal of integrating safety through design principles early in the design and redesign processes?

  • To address hazards and risks early

  • To reduce the need for safety training for employees

  • To ensure that safety is considered only during the construction phase

  • To limit the use of personal protective equipment (PPE) in the workplace

Correct answer: To address hazards and risks early

The primary goal of integrating safety through design principles early in the design and redesign processes is to address hazards and risks at an early stage, making safety considerations an integral part of the design process. This proactive approach helps to avoid costly retrofitting and ensures that safety is embedded into the facilities, processes, and products from the beginning. 

Reducing the need for safety training, focusing only on the construction phase, and limiting the use of PPE are not the primary objectives of safety through design.

122.

What does the acronym LASER stand for?

  • Light Amplification by Stimulated Emission of Radiation

  • Light Absorption by Selective Emission of Rays

  • Luminous Amplification by Stimulated Energy Rays

  • Light Application by Simulated Emission of Radiance

Correct answer: Light Amplification by Stimulated Emission of Radiation

LASER stands for "Light Amplification by Stimulated Emission of Radiation," which accurately describes the process of creating a focused beam of light through stimulated emission. 

The other options provide incorrect interpretations of the acronym. "Light Absorption by Selective Emission of Rays" is incorrect because it describes a different process. "Luminous Amplification by Stimulated Energy Rays" is a mix-up of similar terms but is not the correct acronym. "Light Application by Simulated Emission of Radiance" again misuses the terms and does not accurately reflect the meaning of LASER.

123.

Which of the following is an element that should be included in an OSHA-compliant safety and health program?

  • Hazard identification and evaluation

  • Maintenance schedule for non-hazardous equipment

  • Employee break time allocation

  • Payroll processing procedures

Correct answer: Hazard identification and evaluation

Hazard identification and evaluation are critical components of an OSHA-compliant safety and health program because they involve assessing workplace conditions to identify potential risks that could cause harm to employees. Regular evaluation ensures that hazards are recognized and mitigated to maintain a safe working environment. 

The maintenance schedule for non-hazardous equipment, while important, does not directly pertain to the identification and control of workplace hazards that OSHA focuses on. Employee break time allocation is related to worker well-being but not to the systematic identification and evaluation of hazards. Payroll processing procedures are administrative tasks that have no direct impact on workplace safety and health.

124.

Which of the following scenarios BEST exemplifies an overexertion type of accident?

  • A worker sustains a wrist injury from repeatedly flexing the wrist while using a manual tool

  • A worker slips on a wet floor while carrying a heavy box

  • A worker trips over a loose cable and falls to the ground

  • A worker is exposed to toxic gases while operating in a poorly ventilated area

Correct answer: A worker sustains a wrist injury from repeatedly flexing the wrist while using a manual tool

This situation is a classic example of overexertion, as it involves repetitive motion that causes strain and injury to the body. Overexertion injuries are often associated with tasks that involve excessive physical strain, such as sprains, strains, or repetitive stress injuries.

In contrast, the scenario of a worker slipping on a wet floor involves a fall, not overexertion. Similarly, a trip over a loose cable is also a fall-related incident. The scenario where a worker is exposed to toxic gases relates to environmental hazards rather than overexertion. 

125.

Which of the following sensory concepts has the HIGHEST retention rate among adult learners? 

  • Teaching others

  • Lecture

  • Discussion group

  • Audiovisual

Correct answer: Teaching others

Teaching others has an average of a 90% retention rate among adult learners, according to the Learning Pyramid. This is based on research conducted by the National Training Laboratories. The descending order of average retention rates among adult learners according to the pyramid is: 

  • Lecture (5%)
  • Reading (10%)
  • Audiovisual (20%)
  • Demonstration (30%)
  • Discussion Group (50%)
  • Practice by Doing (75%)
  • Teaching Others (90%)

126.

Class C fires are characterized by the involvement of which of the following?

  • Energized electrical equipment like wiring, controls, and motors

  • Flammable liquids like gasoline or oil

  • Combustible metals such as magnesium and sodium

  • Common combustibles such as wood, paper, or cloth

Correct answer: Energized electrical equipment like wiring, controls, and motors

Class C fires involve energized electrical equipment, such as wiring, controls, motors, data processing panels, or appliances. These types of fires are unique because they can be caused by a spark, power surge, or short circuit, and typically occur in locations where it may be difficult to access the source. 

Flammable liquids and combustible metals are associated with Class B and Class D fires, respectively, while common combustibles like wood, paper, and cloth fall under Class A fires. Therefore, the correct identification for a Class C fire involves energized electrical equipment.

127.

Which type of sprinkler system is most commonly installed in areas where there is a potential for freezing, making the system inoperable if water is present in the pipes?

  • Dry pipe systems

  • Wet pipe systems

  • Deluge systems

  • Pre-action systems

Correct answer: Dry pipe systems

Dry pipe systems are commonly installed in areas where there is a potential for freezing, which would render a wet pipe system inoperable if water were present in the pipes. In dry pipe systems, the pipes are filled with air or nitrogen, and water is only released into the pipes when the system is triggered by a fire. 

Wet pipe systems have water in the pipes at all times and are the most frequently installed system in areas where freezing is not a concern. Deluge systems are used in areas with special hazards requiring rapid water release, and pre-action systems are hybrids of wet, dry, and deluge systems used in areas where accidental discharge is undesirable.

128.

What BEST defines an acceptable risk?

  • A risk for which the probability of occurrence and severity of harm are as low as reasonably practicable and tolerable, taking into account feasibility and effectiveness of risk reduction measures.

  • A risk that can be completely eliminated through engineering controls, ensuring no chance of occurrence or harm.

  • A risk that only requires administrative controls to manage, such as training and signage, without the need for engineering or personal protective equipment.

  • A risk that is ignored due to budget constraints, assuming that the cost of mitigation is too high relative to the perceived benefits.

Correct answer: A risk for which the probability of occurrence and severity of harm are as low as reasonably practicable and tolerable, taking into account feasibility and effectiveness of risk reduction measures.

An acceptable risk is one where the probability of a hazard-related incident and the severity of any resulting harm are minimized to levels that are as low as reasonably practicable and tolerable, considering both feasibility and effectiveness of the measures taken. 

A risk being completely eliminated through engineering controls, although ideal, is not always possible and does not define acceptable risk. 

Managing risk solely with administrative controls like training and signage is insufficient, as effective risk management usually requires a combination of controls. 

Ignoring a risk due to budget constraints is not an acceptable practice in safety management, as it disregards the importance of balancing costs with necessary risk reduction.

129.

Which statement BEST describes the requirements for medical surveillance before an employee can use a respirator?

  • Employers must provide a medical evaluation to determine fitness before initial fit-testing and respirator use

  • Employers must ensure all respirator users, including dust mask users, undergo an annual physical exam

  • Employees can self-certify their fitness by completing an online health assessment

  • Employers need to provide a medical evaluation only if an employee reports a medical condition

Correct answer: Employers must provide a medical evaluation to determine fitness before initial fit-testing and respirator use

Employers must provide a medical evaluation to determine each employee’s fitness to wear a respirator before initial fit-testing and prior to using a respirator for the first time. This evaluation can include a mandatory questionnaire or a physical examination. 

Annual physical exams for all respirator users, including dust masks, are not required. 

Self-certification via an online health assessment is not permitted as medical evaluations must be conducted by a qualified healthcare provider. 

Finally, requiring a medical evaluation only if the employee reports a medical condition is insufficient, as proactive evaluations are required before respirator use.

130.

What is the key requirement for welding or cutting operations in hazardous locations?

  • Welding and cutting operations should be permitted only after ensuring all fire and explosion hazards have been eliminated.

  • Welding and cutting can proceed if the area has been marked off with caution tape.

  • Operations should be performed only if the containers in the area are tightly sealed.

  • No special precautions are necessary if the area is well-lit and ventilated.

Correct answer: Welding and cutting operations should be permitted only after ensuring all fire and explosion hazards have been eliminated.

Marking the area with caution tape or tightly sealing containers does not address the underlying hazards. While good lighting and ventilation are important, they do not replace the need to eliminate potential sources of fire or explosions in hazardous locations.

131.

Why is it important to bond and ground a drum when filling it with flammable liquid?

  • To prevent the build-up of static electricity that could cause a spark and ignite the flammable liquid

  • To increase the speed of the filling process

  • To ensure that the liquid flows more smoothly into the barrel

  • To reduce the temperature of the liquid during the transfer

Correct answer: To prevent the build-up of static electricity that could cause a spark and ignite the flammable liquid

Bonding and grounding a drum during the filling of flammable liquids are key safety practices. The primary purpose of bonding and grounding is to prevent the build-up of static electricity, which could potentially cause a spark, leading to the ignition of the flammable liquid. 

The idea that bonding and grounding could increase the speed of the filling process is incorrect; these practices do not affect the rate of transfer. Similarly, while ensuring smooth flow is important, bonding and grounding do not directly influence the smoothness of liquid transfer. Grounding and bonding have no impact on reducing the temperature of the liquid during the filling process; their purpose is purely to prevent static electricity hazards.

132.

Which of the following statements accurately describes occupational noise-induced hearing loss?

  • It is always sensorineural, affecting hair cells in the inner ear

  • It is always unilateral, affecting only one ear

  • It typically produces profound hearing loss across all frequencies

  • It typically affects low-frequency hearing more than high-frequency hearing

Correct answer: It is always sensorineural, affecting hair cells in the inner ear

Occupational noise-induced hearing loss (NIHL) is always sensorineural, meaning it affects the hair cells in the inner ear, distinguishing it from other types of hearing loss that might affect different parts of the ear. 

NIHL is almost always bilateral, affecting both ears rather than just one. 

NIHL rarely produces profound hearing loss across all frequencies; it usually impacts specific frequency ranges, particularly those associated with the noise exposure. 

Typically, high-frequency hearing is more affected than low-frequency hearing in cases of NIHL.

133.

What is one of the key responsibilities of a safety professional during the development of a safety and health training?

  • Knowing and understanding regulatory requirements and providing this information for the ROI analysis to ensure compliance and effectiveness of the training program

  • Conducting the training sessions directly with all employees to ensure they understand the material

  • Creating all training materials independently without input from other team members or stakeholders

  • Evaluating the effectiveness of the training program immediately after its development and making necessary adjustments

Correct answer: Knowing and understanding regulatory requirements and providing this information for the ROI analysis to ensure compliance and effectiveness of the training program

A key responsibility of a safety professional during the development of a safety and health training program is to know and understand the regulatory requirements and provide this information for the ROI (Return on Investment) analysis. This information is also shared with the training developer to ensure that the training program meets all necessary regulations and standards. 

Conducting training sessions directly and creating all training materials independently are not primary responsibilities at this stage. Evaluating the effectiveness of the training program occurs after implementation, not immediately after development.

134.

According to OSHA, how often must portable fire extinguishers be visually inspected?

  • Monthly 

  • Annually

  • Biannually

  • Weekly

Correct answer: Monthly 

OSHA mandates that portable fire extinguishers undergo visual inspections on a monthly basis to ensure they are in proper working condition and can be readily accessed in case of an emergency. This frequent inspection helps identify any potential issues such as damage, corrosion, or pressure loss that could render the extinguisher ineffective. 

Annual inspections and servicing are also required, but the primary focus for visual checks is monthly. Biannual inspections would not provide the same level of oversight, potentially allowing issues to go unnoticed for too long. Weekly inspections, while thorough, are not required and could be seen as overly frequent, potentially leading to unnecessary use of resources.

135.

When do incidents most often occur on escalators?

  • Incidents most often occur when passengers are entering or leaving escalators

  • Incidents most often occur when escalators are under maintenance

  • Incidents most often occur when passengers are using the handrails incorrectly

  • Incidents most often occur when escalators are operating at high speeds

Correct answer: Incidents most often occur when passengers are entering or leaving escalators

Incidents on escalators are most common when passengers are entering or leaving the escalators, due to the transitions and changes in movement required at these points. 

While maintenance activities, improper use of handrails, and high-speed operation can pose risks, they are less frequent causes of incidents compared to the entry and exit points of escalators.

136.

Which of the following is NOT one of the major types of Employee Assistance Programs (EAPs)?

  • Peer-based EAP

  • Internal EAP

  • Union-based EAP

  • Consortium EAP

Correct answer: Peer-based EAP

Peer-based EAPs are not a recognized type of EAP. The major types of Employee Assistance Programs (EAPs) include internal EAPs, where services are delivered by professionals employed by the organization; union-based EAPs, where services are delivered by trained union personnel to union members; and consortium EAPs, where a group of smaller companies band together to jointly contract with an EAP. 

137.

Which of the following items are considered MOST essential emergency equipment for every vehicle?

  • Fire extinguisher, essential tools for road repairs, spare bulbs, flares, and reflectors

  • GPS device, first aid kit, and blankets

  • Fire extinguisher, tire jack, spare tire, water, and sweatshirts 

  • Fire extinguisher, mobile phone, flashlight, and snacks

Correct answer: Fire extinguisher, essential tools for road repairs, spare bulbs, flares, and reflectors

Every vehicle must be equipped with essential emergency equipment to ensure safety and preparedness in case of emergencies. This equipment includes a fire extinguisher, tools for road repairs, spare bulbs, flares, and reflectors. These items are necessary to handle emergencies like fires, collisions, or road breakdowns effectively. 

GPS devices, mobile phones, sweatshirts, snacks, and other options may be useful in an emergency but are not required emergency equipment for each motor vehicle. 

138.

What is the significance of a gas or vapor having a vapor density greater than one in an indoor environment?

  • The gas or vapor will sink and accumulate near the floor or lower levels

  • The gas or vapor will rise and accumulate near the ceiling

  • The gas or vapor will disperse evenly throughout the room

  • The gas or vapor will evaporate rapidly, reducing the concentration near the source

Correct answer: The gas or vapor will sink and accumulate near the floor or lower levels

A gas or vapor with a vapor density greater than one is heavier than air, which means it will tend to sink and accumulate near the floor or lower levels of an indoor environment. This is a critical consideration when designing ventilation systems or assessing the risk of hazardous gas accumulation. 

The idea that the gas or vapor will rise and accumulate near the ceiling is incorrect because that would be true for gases with a vapor density less than one, which are lighter than air. The statement that the gas will disperse evenly is not accurate because vapor density affects how gases and vapors settle in a space. The evaporation rate is a separate concept and does not directly relate to vapor density, so the idea that the gas would evaporate rapidly is also incorrect.

139.

Which of the following is an important consideration when developing a safety budget?

  • Protection and training of equipment operators

  • Cost of marketing materials

  • Employee vacation expenses

  • Office supply costs

Correct answer: Protection and training of equipment operators

When developing a safety budget, a crucial consideration is the protection and training of equipment operators, as this directly impacts workplace safety and reduces the likelihood of accidents. The budget should also account for safeguards on machinery, firefighting needs, and any potential disruptions to production due to safety incidents. 

Costs associated with marketing materials, employee vacation expenses, and office supplies are not directly related to the safety budgeting process and therefore are not priorities in this context.

140.

What is a PRIMARY benefit of emphasizing safety in a company's PR program?

  • It helps mitigate adverse news should incidents occur

  • It helps the company save money on advertising costs

  • It ensures that the company’s products are always high quality

  • It reduces the need for employee training programs

Correct answer: It helps mitigate adverse news should incidents occur

Emphasizing safety in a company's PR program is crucial because it can help offset or mitigate adverse news if incidents happen. By having a strong safety program in place and effectively communicating it to both internal and external audiences, the company can manage public perception better and reduce the negative impact of any incidents. 

Saving money on advertising costs is not a primary benefit of a safety-focused PR program. 

Ensuring product quality is also not directly related to the PR emphasis on safety. 

Reducing the need for employee training programs is not mentioned as a benefit either.
