The university is dedicated to providing safe and healthful work facilities for students and employees, and complying with federal and state occupational health and safety standards. Engineering controls should be instituted to the maximum extent feasible to maintain exposures below permissible limits, followed by other control methods including work and hygienic practices, and the use of personal protective equipment such as eye, face, skin, and respiratory protection. Administrators, managers, faculty, staff, and students all share responsibility for minimizing their exposure to formaldehyde.
This plan applies to all University employees who are exposed or potentially exposed to formaldehyde gas, its solutions, and materials that release formaldehyde.
This program has the following objectives:
A concentration of formaldehyde of 0.5 parts formaldehyde per million parts of air (0.5 ppm) calculated as an 8- hour time-weighted average (TWA) concentration.
Any person required by work duties to be present in regulated areas, or authorized to do so by the University.
The chemical substance, HCHO, Chemical Abstracts Service Registry No. 50-00-0. The precise hazards associated with exposure depend both on the form (solid, liquid, or gas) of the material and the concentration present. 37-50% solutions of formaldehyde used in preserving specimens present a much greater hazard to the skin and eyes due to splashes than solutions containing less than 1%. Formaldehyde is also found in urea-formaldehyde resins (e.g., glues used in plywood and particle board) and can generate formaldehyde-bearing dust when cut, sanded, drilled, or broken.
Identification of all employees who may be exposed at or above the action level or at or above the STEL and accurately determine the formaldehyde exposure of each employee so identified. Initial monitoring shall be repeated each time there is a change in production, equipment, process, personnel, or control measures which may result in new or additional exposures to formaldehyde.
Engineering and work practices implemented to reduce and maintain employee exposures to formaldehyde at or below the TWA and the STEL.
Parts per million.
The allowable exposure that an employee can be exposed to over an 8-hour Time-Weighted Average (TWA). For formaldehyde, the limit is 0.75 parts per million (ppm).
Employees shown by initial monitoring to be at or above the action level or at or above the STEL shall be periodically monitored. If the last monitoring showed the employee exposure at or above the action level, then repeat monitoring of the employee shall be performed at least once a year under worst-case conditions.
A limit of 2 ppm of formaldehyde, averaged over a 15-minute period.
Areas where the concentration of airborne formaldehyde exceed the PEL or STEL. All entrances and access ways shall be posted with a sign as indicted in this Plan.
The average exposure to formaldehyde an individual receives for a full eight-hour day.
All laboratories having any form of formaldehyde in the workplace must monitor employee exposure unless the occupants can objectively document (i.e. through calculations) that the presence of airborne formaldehyde will not exceed the action level (AL) or short-term exposure level (STEL) under foreseeable conditions.
When there are different processes where employees may be exposed to formaldehyde, EH&S will select a maximum risk employee. This will be accomplished by observing the worksite. If measurements show exposure to formaldehyde at or above the action level or the STEL, then all employees identified in the same group will be monitored.
A personal air sample will be undertaken for all routine users of formaldehyde and those who are believed to be exposed from an identified source. TWA's are usually determined for an 8-hour work shift. STEL assessments are 15-min samples taken during periods of maximum expected concentrations. Multiple STEL measurements may be collected per shift, and only the highest concentration is used to represent the employee's STEL. Employee exposures determine the need for compliance with provisions of the regulation and the Formaldehyde Management Plan.
For those exposed continuously to formaldehyde in the workplace, their exposure will be compared to the eight-hour time weighted average (TWA) limit of 0.75 ppm and the action level of 0.5 ppm. For employees who experience brief exposures, their exposure will be compared to the 15-minute short-term exposure limit (STEL). Monitoring results determine the need and extent of employee training, hygiene procedures, personal protective equipment, follow-up monitoring, and medical surveillance.
This initial monitoring will serve to separate TWA exposures into three categories:
Employees will be notified within 15 days of when the test results are received about their personal exposure. If personal exposure is greater than the permissible exposure limits of 0.75 ppm for a TWA and 2.0 ppm for a STEL, a written plan to reduce exposure must be provided to the affected employee.
Periodic monitoring will be terminated when two consecutive air samples (at least 7 days apart) result in concentrations below the action level and the STEL.
Air sampling will be repeated when there is a change in procedure, equipment, personnel, or control measures. It is the responsibility of the department supervisor to notify EH&S when any of these changes occur. Air sampling will also be repeated when an employee reports respiratory or dermal conditions believed to be caused by formaldehyde.
Following are the health hazards as reported in Appendix A of this OSHA regulation. Specific information about commercial mixtures or formulations may be obtained from manufacturers’ material safety data sheets.
Employees who are assigned to workplaces where exposure to formaldehyde has been documented at or above 0.1 ppm will participate in the formaldehyde training program. The elements include:
Employees shall receive information and training at the time of initial assignment, and whenever there is a change in procedure that may result in a new exposure. EH&S shall provide the training annually to each affected employee.
A medical surveillance program will be instituted, if warranted, for all employees exposed to formaldehyde at concentrations at or exceeding the action level or exceeding the STEL.
Medical surveillance will be available for employees who develop signs and symptoms of overexposure to formaldehyde, and for all employees exposed to formaldehyde in emergencies.
Hazard warning labels should be affixed to all containers of formaldehyde gas, all mixtures, or solutions composed of greater than 0.1% formaldehyde, and materials capable of releasing formaldehyde into the air, under reasonably foreseeable conditions of use, at concentrations reaching or exceeding 0.1 ppm.
For all materials capable of releasing formaldehyde at levels of 0.1 ppm to 0.5 ppm, required label information includes:
For materials capable of releasing formaldehyde at levels above 0.5 ppm, labels will address all hazards included in OSHA 1910.1200 Appendices A and B, including respiratory sensitization and the words "Potential Cancer Hazard."
Material safety data sheets for formaldehyde-containing products will be located in the workplace where it is used and will be readily accessible. The MSDS must be in English and contain the identity of the chemical and it's chemical and common name(s).
The name, address and telephone number of the chemical manufacturer, who can provide additional information on the chemical and appropriate emergency procedures, if necessary, must be listed on the MSDS.
Areas where the concentration of airborne formaldehyde exceeds either the PEL or STEL shall be established as regulated areas. All entrances and access ways shall be posted with a sign bearing the following information.
Ventilation is the most widely applied engineering control method for reducing the concentration of airborne substances in the breathing zones of workers. Either local exhaust ventilation or general dilution ventilation should be used for this purpose whenever possible.
Work practices and administrative procedures are also an important part of a control system. If an employee is asked to perform a task in a certain manner to limit the exposure to formaldehyde, it is extremely important that the recommended procedures are followed.
This may include limiting splashing of formalin solutions, washing formaldehyde-soaked materials in water, and maintaining the covers on containers that emit formaldehyde as much as possible. Surfaces contaminated with formalin solutions should be cleaned as soon as possible in order to limit skin and inhalation exposures. Food and drink consumption and storage should be prohibited from areas where formaldehyde is used and stored to eliminate the potential for ingestion.
Eyewash facilities must be placed within the immediate work area for emergency use if there is any possibility that an employee's eyes may be splashed with solutions containing 0.1 percent or greater of formaldehyde.
Personal Protective equipment shall be required according to the task or area where formaldehyde is used or stored. Parts of the body that may need to be protected include eyes, nose and mouth, hands, arms and the trunk of the body. Butyl and nitrile rubber are materials that are effective in limiting penetration of formalin solutions to the skin.
If an employee might be splashed in the eyes with formalin solutions, goggles are the appropriate eye protection. If significant splashing is likely, a face shield in combination with goggles is recommended.
Gloves of appropriate material and thickness for the task should be used to protect hands. For a task that may produce splashes to the trunk of the body, an impermeable suit or rubber apron should be worn to prevent work or street clothing from becoming wet and contacting the skin.
At minimum, personnel working around specimens containing formalin or formaldehyde shall wear safety glasses with side shields and gloves, preferably nitrile.
If an employee must work in an area where the formaldehyde concentration cannot be controlled within the TWA or STEL, a respirator must be worn. Respirator use requires a medical examination, training, and fit testing prior to its first use. Other than for emergency situations, this should not be necessary if appropriate work practices and engineering controls are implemented.
Whenever feasible engineering and work practice controls (for example, local exhaust ventilation) cannot reduce employee exposure below the PEL or STEL, the employer shall continue to apply these controls to reduce employee exposures to the maximum extent feasible and shall supplement them with respirators when required.
Respirators must be used:
The use of respiratory protection shall be in accordance with the University’s Respiratory Protection Program and OSHA 1910.134. All workers must be medically evaluated and fit tested to determine the ability of the worker to perform the work while wearing a respirator. EH&S can provide referrals to local agencies who can conduct these evaluations, if needed. Training in the care and use respirators will be conducted by EH&S, or an EH&S approved contractor, for only those employees who are authorized to wear a respirator. Any worker who is not authorized will be prohibited from engaging in activities that may expose the worker to airborne formaldehyde at or above the PEL.
Employee exposure monitoring results shall be maintained by
Environment, Health and Safety. The records shall include: the date
of the measurement; the operation being monitored; the methods of
sampling and analysis and evidence of their accuracy and precision;
the number, duration, time, and results of samples taken; types of
protective devices worn, if any, and the names, job
classifications, and exposure estimates of the employees whose
exposures are represented by the actual monitoring results.
Where EH&S has determined that no monitoring is required under this policy, a record of the objective data relied upon to support the determination that no employee is exposed to formaldehyde at or above the action level shall be maintained.
If deemed necessary through exposure, EH&S shall maintain
all Respiratory Protection Records mandated.
EH&S will retain records required by this standard for at least the following periods:
Upon request, EH&S will make all records maintained as a
requirement of this standard available for examination and copying
to the Assistant Secretary of Labor and the Director of
EH&S will make employee exposure records, including estimates made from representative monitoring and available upon request for examination, and copying to the subject employee, or former employee, and employee representatives in accordance with the OSHA regulation covering Access to Employee Exposure and Medical Records.
Employee medical records required by this standard will be provided upon request for examination and copying, to the subject employee or former employee or to anyone having the specific written consent of the subject employee or former employee in accordance with the OSHA regulation covering Access to Employee Exposure and Medical Records.
For areas where formaldehyde solutions of 1% or greater are used or stored, an emergency shower must be conveniently located. Areas that use formaldehyde solutions of 0.1% or greater must have an emergency eyewash located within the immediate work area. If a person's eyes, skin, or clothing are splashed with a formalin solution, the affected area should be washed with water for at least 15 minutes. For overexposure to formaldehyde gas, the affected person should be moved away from the source into fresh air. If there are symptoms of overexposure, the person should report to their supervisor, EH&S, and seek medical attention.
Small spills (less than one pint) may be cleaned up by those responsible for creating the spill. The spilled material should be absorbed with paper towels or other absorbing media. The absorbing material should be rinsed thoroughly with water in a sink, or disposed of through EH&S. Washed media may then be discarded with the regular trash.
Spills of more than one pint may create significant exposure for those responsible for cleaning up the spills. A spill of this size should be handled through EH&S. Contact EH&S directly during normal working hours, or University Police at after hours or on weekends.
This program shall be reviewed by EH&S in the fourth quarter of each year, and subsequently updated as necessary.
