CESCO - Certified Environmental, Safety and Compliance Officer Occupational Safety Standards (OSHA) Questions and Answers — Questions and Answers
Question 1: A CESCO is reviewing a company's injury and illness records. Which OSHA form provides a detailed narrative of each specific recordable incident, including the sequence of events and the nature of the injury?
- OSHA Form 300A (Summary of Work-Related Injuries and Illnesses)
- OSHA Form 300 (Log of Work-Related Injuries and Illnesses)
- OSHA Form 301 (Injury and Illness Incident Report) (Correct answer)
- The employer's internal accident investigation form
Correct answer: OSHA Form 301 (Injury and Illness Incident Report)
OSHA Form 301, the Injury and Illness Incident Report, is used to record the specific details of each incident. The OSHA 300 Log is a running list of all recordable incidents, and the 300A is an annual summary of the log. While an employer's internal form is important, the OSHA 301 is the official, required document for detailed incident reporting.
Question 2: During a site walkthrough, a compliance officer observes an employee preparing to perform maintenance on a machine. The employee has shut down the machine but has not applied a lock or tag to the main energy isolating device. According to OSHA's Lockout/Tagout (LOTO) standard (29 CFR 1910.147), what is the primary purpose of affixing a lock or tag?
- To inform other workers that the machine is out of service.
- To prevent the unexpected energization or startup of the machine during servicing. (Correct answer)
- To track the maintenance schedule and history of the equipment.
- To identify the authorized employee who is performing the maintenance.
Correct answer: To prevent the unexpected energization or startup of the machine during servicing.
The core purpose of the Lockout/Tagout standard is to prevent the release of hazardous energy by disabling machinery or equipment, thereby preventing unexpected energization, start-up, or release of stored energy during servicing and maintenance activities. While LOTO devices do identify the user and indicate the machine is being serviced, their primary function is to control hazardous energy.
Question 3: A manufacturing facility uses a variety of hazardous chemicals. Under OSHA's Hazard Communication Standard (HCS), which of the following is the employer's responsibility regarding Safety Data Sheets (SDSs)?
- To create new SDSs for any chemical mixtures created on-site.
- To provide SDSs only for the most hazardous chemicals used.
- To ensure SDSs are readily accessible to employees during their work shifts. (Correct answer)
- To submit all SDSs to OSHA for annual review and approval.
Correct answer: To ensure SDSs are readily accessible to employees during their work shifts.
OSHA's Hazard Communication Standard requires employers to maintain copies of SDSs for each hazardous chemical in the workplace and ensure that they are readily accessible to employees when they are in their work areas. Employers are not required to create SDSs for mixtures (this is the manufacturer's duty), provide them only for select chemicals, or submit them to OSHA for approval.
Question 4: A construction company has a worksite with a large underground vault that workers must enter to perform inspections. The vault has limited openings for entry and exit and is not designed for continuous occupancy. Before any worker enters, what is the correct order for atmospheric testing inside this permit-required confined space?
- Flammable gases, toxic contaminants, then oxygen content.
- Oxygen content, flammable gases and vapors, then potential toxic air contaminants. (Correct answer)
- Toxic contaminants, oxygen content, then flammable gases.
- The order does not matter as long as all three are tested.
Correct answer: Oxygen content, flammable gases and vapors, then potential toxic air contaminants.
OSHA standard 29 CFR 1910.146 explicitly states that before an employee enters a permit-required confined space, the internal atmosphere must be tested in a specific order: first for oxygen content, second for flammable gases and vapors, and third for potential toxic air contaminants. This sequence is critical because the presence of oxygen can affect the flammability readings, and both oxygen levels and flammability are essential to determine before assessing toxicity.
Question 5: A CESCO is developing a Personal Protective Equipment (PPE) program. According to OSHA general industry standards (29 CFR 1910 Subpart I), which of the following is the first step an employer must take before providing PPE to employees?
- Ordering a variety of PPE sizes and types to have in stock.
- Training employees on the proper use and care of PPE.
- Conducting a 'hazard assessment' of the workplace. (Correct answer)
- Requiring employees to purchase their own certified PPE.
Correct answer: Conducting a 'hazard assessment' of the workplace.
OSHA requires employers to first assess the workplace to determine if hazards are present, or are likely to be present, which necessitate the use of personal protective equipment (PPE). This hazard assessment is the foundational step that informs the selection of appropriate PPE, the development of training, and the overall structure of the PPE program.
Question 6: An employer is required to post the OSHA Form 300A, the Summary of Work-Related Injuries and Illnesses. For what period must this summary be displayed in a conspicuous place for employees to view?
- The entire calendar year following the year covered by the form.
- From January 1 to January 31 of the next year.
- From March 2 to April 30 of the next year.
- From February 1 to April 30 of the next year. (Correct answer)
Correct answer: From February 1 to April 30 of the next year.
OSHA's recordkeeping rule requires employers to post the OSHA Form 300A Summary from February 1 to April 30 of the year following the year covered by the summary. This three-month period ensures that employees have ample opportunity to review the summary of injuries and illnesses that occurred in their workplace.
