Correct: Under OSHA 29 CFR 1910.119 for Process Safety Management, a HAZOP study is a recognized Process Hazard Analysis (PHA) method. It involves a multidisciplinary team systematically applying guide words, such as ‘No’, ‘More’, or ‘Less’, to process parameters like flow or pressure. This identifies how a process might deviate from its design intent, allowing the team to evaluate the causes and consequences of these deviations and implement necessary safeguards.

Incorrect: Relying on the calculation of probability and severity numbers describes Failure Mode and Effects Analysis (FMEA) rather than the qualitative guide-word approach of a HAZOP. The strategy of comparing equipment against a standardized list of specifications is a checklist method, which lacks the exploratory depth and team-based brainstorming required for a HAZOP. Focusing only on retrospective near-miss reports is a reactive incident investigation technique that does not proactively identify potential deviations from design intent in new or existing systems.

Takeaway: HAZOP identifies process hazards by applying guide words to design parameters to uncover potential operational deviations.

Correct: OSHA standard 29 CFR 1910.132(d) requires employers to perform a hazard assessment to determine if PPE is necessary. The employer must verify this assessment through a written certification.

Incorrect: Distributing a list for personal procurement is insufficient. The employer must ensure equipment meets safety standards and matches the hazard. Conducting fit tests for all PPE is technically incorrect. Fit testing is a specific requirement for respirators, not a general first step for all gear. Relying solely on historical injury logs is a reactive approach. It fails to meet the proactive requirement of identifying current hazards through a formal assessment.

Correct: Under OSHA’s ergonomic guidelines and the hierarchy of controls, engineering controls like hydraulic lift tables are preferred because they physically change the environment to reduce or eliminate the hazard.

Incorrect: Relying on personal protective equipment such as lumbar belts is considered the least effective method as it does not reduce the physical demand of the task. The strategy of implementing stretching programs is an administrative control that fails to address the underlying ergonomic stressors. Choosing to mandate two-person lifts may introduce new coordination risks and does not provide a permanent engineering solution to the lifting hazard.

Takeaway: Engineering controls that eliminate manual lifting are the most effective way to prevent musculoskeletal injuries in the workplace.

Correct: Under OSHA standard 1910.132(d)(2), employers are required to verify that the required workplace hazard assessment has been performed through a written certification. This document must specifically identify the workplace evaluated, the person certifying that the evaluation has been performed, and the date of the hazard assessment.

Correct: Active monitoring involves the systematic inspection of the workplace to ensure that standards are being maintained. By conducting unannounced inspections and verifying fall arrest systems, the organization identifies non-compliance before an incident occurs. This proactive approach is a core component of an effective safety management system under OSHA guidelines.

Correct: Under the OSHA Hazard Communication Standard, employers are required to maintain a written program and ensure employees are trained on the specific health hazards of the chemicals they encounter. When a substance is newly identified as a carcinogen, mutagen, or reproductive toxin (CMR), the employer must update the program and provide training so workers understand the risks and necessary precautions.

Incorrect: Focusing only on financial disclosures to the Securities and Exchange Commission (SEC) addresses corporate liability but fails to meet the legal requirement to protect worker health under safety regulations. The strategy of requiring genetic screening is a violation of privacy laws and does not fulfill the employer’s duty to control workplace hazards. Choosing to use a single generic sign at the facility entrance violates the federal requirement for specific hazard warnings and pictograms on individual chemical containers. Relying solely on administrative notices without updating the actual safety documentation and training protocols leaves workers at risk of uninformed exposure.

Takeaway: Employers must update hazard programs and provide specific training whenever a substance is newly classified with CMR properties under federal safety standards.

Correct: ISO 45001 emphasizes the importance of consultation and participation of workers, particularly non-managerial staff, in the OHSMS. By involving these workers in hazard identification and control determination, the organization leverages their practical experience to create a safer work environment, fulfilling a core requirement of the standard.

Correct: According to OSHA’s Hazard Communication Standard (29 CFR 1910.1200), an employer is not required to label portable containers into which hazardous chemicals are transferred from labeled containers, provided the portable container is intended only for the immediate use of the employee who performs the transfer.

Incorrect: Focusing on storage in locked cabinets does not address the fundamental requirement for hazard communication or the specific conditions of the transfer exemption. The strategy of requiring employees to carry physical Safety Data Sheets is a procedural choice but does not legally substitute for the labeling requirements of secondary containers. Opting for a volume-based limit like one gallon is an incorrect interpretation, as the HCS exemption is based on the user and the immediacy of use rather than a specific numerical threshold.

Takeaway: The OSHA labeling exemption for secondary containers applies only when the person who transfers the chemical uses it immediately.

Correct: Section 8 of the Safety Data Sheet is specifically designated under OSHA’s Hazard Communication Standard to include exposure limits such as PELs. It also details the necessary engineering controls and personal protective equipment required to minimize worker exposure to the chemical.

Incorrect: The strategy of reviewing toxicological information focuses on the health effects and data like LD50 rather than the practical controls needed for workers. Relying on first-aid measures provides instructions for emergency response after an exposure has occurred instead of preventative measures. Choosing to examine physical and chemical properties helps in understanding the substance’s state and reactivity but does not list specific exposure limits or required personal protective equipment.

Takeaway: OSHA requires Section 8 of an SDS to contain the exposure limits and specific protective measures necessary for safe chemical handling.

Correct: According to OSHA 1926.1101 and EPA NESHAP standards, asbestos-containing material must be kept wet during all phases of removal to suppress dust. The waste must then be placed in leak-tight, labeled containers and transported to a disposal site that is specifically permitted to handle asbestos waste to ensure long-term environmental safety.

Correct: Under OSHA 1910.333, de-energized parts must be treated as energized until they are verified as de-energized. A qualified person must use test equipment to verify that the circuit elements and electrical parts are de-energized. This step is critical to ensure that the isolation was effective and that no unexpected energy sources or back-feeds are present.

Correct: Investigating root causes is the most effective strategy because it identifies systemic failures in the ventilation design and management programs. This approach allows the facility to implement engineering and administrative controls that eliminate the hazard at its source. This process is consistent with OSHA’s Incident Investigation guidelines, which emphasize finding the underlying reasons behind an accident to prevent its recurrence.

Incorrect: Focusing only on safety meetings and respirator use places the burden of safety on the employee rather than addressing the environmental hazard. The strategy of updating manuals and collecting signatures is a clerical task that does not identify or fix the physical cause of the vapor leak. Opting for more emergency equipment like eyewash stations is a reactive measure that does not prevent the exposure from happening in the first place.

Takeaway: Effective accident prevention focuses on identifying and correcting systemic root causes rather than relying on reactive measures or individual worker compliance.

Correct: Under OSHA standard 29 CFR 1910.95, employers are required to implement a monitoring program when noise exposure equals or exceeds an 8-hour time-weighted average (TWA) of 85 decibels. The standard specifically requires that the monitoring program be designed to identify employees for inclusion in a hearing conservation program. Representative personal sampling is necessary when factors such as high worker mobility or significant variations in sound levels make stationary area monitoring inaccurate for determining individual exposure.

Incorrect: Relying on area monitoring alone is insufficient for mobile employees because it fails to capture the cumulative noise levels they encounter while moving through different acoustic environments. Focusing only on impact noise is incorrect because the 8-hour TWA must include all continuous, intermittent, and impulsive noise within the 80 to 130 decibel range. The strategy of monitoring during low-capacity shifts is flawed because the assessment must reflect the actual hazards present during normal operating conditions to ensure worker safety.

Takeaway: Employers must use representative personal sampling to identify workers exceeding the 85 dBA TWA action level for hearing conservation inclusion.

Correct: A critical component of a permit-to-work system is the formal hand-back, where the issuer verifies that the work is complete, the site is clean, and it is safe to return to service.

Incorrect: Relying solely on digital timestamps fails to account for the physical state of the equipment or the presence of forgotten tools and materials. The strategy of self-certification by the maintenance crew removes the necessary independent oversight required to confirm that the area is truly safe for others. Opting for a mandatory cooling-off period is an arbitrary time-based measure that does not substitute for a physical inspection of the actual work conditions.

Takeaway: Effective permit-to-work systems require a formal hand-back process involving a physical inspection to confirm the work area is safe.

Correct: The Statement of Intent is the primary vehicle for senior management to express their commitment to health and safety. It establishes the organization’s safety philosophy, sets broad objectives, and is signed by the highest-ranking official to demonstrate leadership and accountability within the United States regulatory environment.

Incorrect: The strategy of using the Organization Section is incorrect because that area focuses on the hierarchy of safety roles and specific duties rather than the overall commitment. Focusing only on the Arrangements Section is insufficient as this part of the policy details the specific procedures for managing hazards rather than the high-level goals. Choosing the Emergency Action Plan is inappropriate because that document is a specific operational response plan for crises rather than a broad statement of safety policy.

Takeaway: The Statement of Intent defines the organization’s safety goals and must be signed by senior leadership to establish accountability.

Correct: Acute health effects are characterized by a rapid onset of symptoms shortly after exposure to a hazardous substance, which aligns with the immediate skin and respiratory reactions observed in the workers.

Incorrect: Relying solely on the definition of chronic disorders is incorrect because these require prolonged exposure over months or years. The strategy of identifying latent effects is misplaced as these specifically refer to conditions that appear long after exposure has ceased. Opting for mutagenic effects is wrong because these involve long-term genetic changes rather than immediate physical symptoms like dizziness or redness.

Takeaway: Acute health effects involve immediate physiological responses following short-term exposure to hazardous chemical substances in the workplace.

Correct: Under United States safety management principles and OSHA guidelines, effective health and safety arrangements must include systematic procedures for identifying hazards and assessing risks. This ensures that the organization can proactively implement control measures tailored to specific workplace activities, effectively translating the general safety policy into actionable operational steps.

Incorrect: The strategy of focusing only on the cost or quality of personal protective equipment fails to address the underlying procedural requirements for managing safety, such as the hierarchy of controls. Relying solely on historical data like injury logs is a reactive approach that does not satisfy the need for proactive hazard identification and planning. Opting to delegate all inspection duties to an external consultant is inappropriate because the employer must maintain internal control and supervision over the safety arrangements to ensure they are integrated into daily work practices.

Takeaway: Effective health and safety arrangements require documented, proactive procedures for hazard identification and risk control to manage workplace safety systematically.

Correct: Under United States federal safety regulations managed by the Department of Labor, employers must report all work-related inpatient hospitalizations, amputations, or losses of an eye within a 24-hour window. This ensures that the federal regulator can investigate serious incidents promptly to prevent further harm.

Incorrect: The strategy of reporting within 8 hours is incorrect as this stricter deadline is reserved specifically for work-related fatalities. Opting for a 72-hour window is a failure of compliance because it exceeds the mandatory federal limit for reporting hospitalizations. Choosing a 7-day timeframe is a common misconception often derived from different international standards or internal recordkeeping logs, but it does not satisfy the immediate notification requirements for serious injuries in the United States.

Correct: Engineering controls that isolate the operator from the source of vibration, such as suspended cabs, provide the highest level of protection by physically reducing the energy transmitted to the body.

Incorrect: Relying solely on administrative controls like job rotation reduces the time of exposure but fails to address the underlying intensity of the vibration hazard. The strategy of using non-integrated padding or gloves is often ineffective for whole-body vibration as these items are typically designed for hand-arm vibration. Choosing to focus only on operator posture is a behavioral approach that does not mitigate the physical forces acting on the spine.

Correct: Under OSHA standards and NFPA 70E guidelines, the frequency of testing and inspection for portable appliances must be determined by the likelihood of damage. Equipment used in harsh industrial environments or handled frequently requires more frequent checks than stationary office equipment. This ensures the continued integrity of the grounding conductor and insulation where the risk of failure is highest.

Incorrect: Simply applying a fixed biennial schedule to all items fails to account for the rapid wear and tear experienced by tools in high-risk areas. The strategy of ignoring lower-voltage office equipment is dangerous because 120V circuits are responsible for many workplace electrocutions. Choosing to wait for a circuit breaker to trip is a reactive failure that allows hazardous conditions to persist undetected. Focusing only on high-voltage machinery overlooks the common risks associated with portable hand tools and extension cords.

Takeaway: Inspection frequency should be determined by a risk assessment of the equipment’s use and environment.
