Which of the following is true of the National Institute for Occupational Safety and Health NIOSH )? Group of answer choices?

The threshold limit values apply for 8-hour workday and 40-hour workweek. When working shifts longer than eight hours, the exposure time is increased and the recovery period between exposures is decreased. In these situations, the threshold exposure limit should be so adjusted that in the end the peak body burden does not exceed the one that would occur during a normal eight hour shift.

There are numerous mathematical models, some simple and some more complex, that can be used to adjust the TLV for chemical exposure to a different work schedule.   ACGIH indicates that the Brief and Scala model is easier to use. This model reduces the TLV by a factor that considers the hours worked daily and the periods of rest between them. There are two reduction factors that can be used to calculate the adjusted TLV: one based on daily exposure, and one based on averaged weekly exposure.

Note: The daily reduction factor does not consider the number of days worked per week (e.g., where workers work 12-hour shifts, 5 days one week and 2 days the next week). The number of days worked in a week is factored in the weekly reduction factor (e.g., where a worker works 9 hours/day, seven days per week).

Both daily and weekly reduction factors should be calculated, and the most stringent result should be considered for use.

ACGIH recommends medical supervision during the initial use of the adjusted TLVs.

For example, the modified TLV-TWA for toluene (TLV-TWA = 20 ppm) for a 12-hr/day 14-day pattern shift (five workdays one week and two workdays the next week) will be:

(The reduction factor is calculated for the 12-hour workday regardless of how many days, 5 or 2, are worked during a week).

Where a worker works 9 hours/day, seven days/week, the modified TLV-TWA for toluene may be:

The TLVadj = 16.65 ppm obtained using the daily adjustment formula should be considered as it is more protective.

One of the shortcomings of the Brief and Scala method is that the reduction factor for a certain amount of worked hours is identical for all chemicals regardless of their individual biological half-lives. This assumption may lead to an overestimation of the degree to which the limit should be lowered.

The formula is not applicable for:

• Work schedules with less than seven to eight hours per day or less than 40 hours per week.
• Work schedules that involve 24-hour continuous exposure (e.g., in submarines and space shuttles).
• Certain irritants.

The National Institute for Occupational Safety and Health (NIOSH) is responsible for conducting research and making recommendations for the prevention of work-related injury and illness. Although NIOSH is generally characterized as a non-regulatory agency, guidance and recommendations issued by NIOSH are often used by other agencies responsible for developing and enforcing workplace safety and health regulations.

NIOSH is also directly responsible for several regulations. These regulations mostly outline procedures and requirements for specific health and safety related matters involving a particular industry or set forth rules for NIOSH to follow in administering programs assigned to the Institute. The regulations include rules regarding the following:

1. The Coal Workers Health Surveillance Program which describes x-ray screening of underground coal miners, autopsies, and operation of the B-reader program for classifying pneumoconiosis;
2. NIOSH grants and educational training programs;
3. Implementation of HHS responsibilities under the Energy Employees Occupational Illness and Compensation Program Act (EEOICPA);
4. Approval of respiratory protective equipment;
5. Conducting investigations at places of employment for the Health Hazard Evaluation (HHE) program and for occupational safety and health research; and
6. Implementation of the World Trade Center Health Program.

The NIOSH regulations are found in the following parts of the Code of Federal Regulations (CFR) and are linked below.

Code of Federal Regulations (CFR)

Formerly Relevant OSHA Requirements: 29 CFR 1910.1020, 29 CFR 1910, subpart Z

Employers are no longer required to notify and transfer records to NIOSH

The Occupational Safety and Health Administration (OSHA) previously required employers to transfer employee exposure and medical records to NIOSH if: (1) the employer was going out of business without a successor, (2) the retention period for records had expired or, (3) due to the termination of a worker’s employment. However, on June 8, 2011, OSHA deleted these transfer requirements from its substance-specific standards in 29 CFR 1910, subpart Z, as well as from its regulation at 29 CFR 1910.20, Access to Employee Exposure and Medical Records. See, 76 Federal Register 33590, 33598. As such, employers are no longer required to notify and/or transfer OSHA-required records to NIOSH.

Although employers are no longer required to notify and/or transfer records to NIOSH, OSHA’s current regulation at 29 CFR 1910.1020(h)(1) provides that whenever an employer is ceasing to do business, they must “transfer all records subject to this section to the successor employer. The successor employer shall receive and maintain these records.”

Also, OSHA’s regulation at 29 CFR 1910.1020(h)(2) requires that: “Whenever an employer is ceasing to do business and there is no successor employer to receive and maintain the records subject to this standard, the employer shall notify affected current employees of their rights of access to records at least three (3) months prior to the cessation of the employer’s business.”
