Background
On August 10, 1992, the Occupational Safety and Health Administration
(OSHA) issued a final standard on the regulation of exposure to
4,4' Methylenedianiline (MDA) in Volume 29 of the Code of
Federal Regulations (29 CFR) Part 1910.1050. Coverage of this
standard applies to general industry (primary chemical manufacture,
reprocessing, filament winding, potting, and encapsulating)
and to the maritime industry. OSHA issued a separate standard for
MDA exposure in the construction industry in 29 CFR 1926.60.
In September 1983, OSHA and the Environmental Protection
Agency (EPA) jointly published an advanced notice of proposed
rulemaking (ANPR). EPA later issued a notice under section 4(f)
of the Toxic Substances Control Act (TSCA) indicating that exposure
to MDA presents a significant risk to humans as a carcinogen.
EPA based this conclusion on studies performed by the National
Toxicology Program (NTP) and on data collected by the Oak Ridge
National Laboratories that supported findings of MDA as a carcinogen
in test animals.1
The ability of MDA to induce tumors in
animals-suggestive evidence that MDA may induce bladder
tumors in humans and data indicating that MDA interacts with
genetic material led to the conclusion that this chemical is an
animal carcinogen and is a possible carcinogen to humans.
On July 5, 1985, EPA referred all MDA rulemaking to OSHA under
section 4(f) of TSCA. In response, OSHA determined -- based on
the previously cited studies -- that there is a reasonable basis to
believe that the manufacture and use of MDA presents a significant
risk to the health of exposed workers and that risk may be
eliminated or reduced to a significant extent by a workplace
standard that regulates workers' exposure.
Routes of exposure to MDA include skin absorption, inhalation,
and ingestion. Short-term (acute) overexposure to MDA may
produce fever, chills, loss of appetite, vomiting, and/or jaundice;
direct contact may irritate skin, eyes, and mucous membranes.
Long-term (chronic) overexposure may cause cancer, even at
relatively low concentrations, and/or damage to the liver, kidneys,
blood, and spleen.
OSHA found thereto be no nonregulatory alternatives that adequately
protect most workers from the adverse health effects
associated with MDA exposure.
MDA is a light brown crystalline solid with a faint amino-like odor.
It is slightly soluble in water and very soluble in alcohol and
benzene. MDA is produced commercially by the condensation of
aniline and formaldehyde. Crude MDA, (40-60 percent) is either a
liquid or a hard wax-like substance. Purified MDA (99 percent) is
either light yellow crystalline flakes or white granules.
Ninety-eight percent of MDA currently produced is used directly in
the manufacture of 4,4' Methylenediphenyl diisocyanate (MDI). 2
The remaining 2 percent of MDA is used as a precursor for the
manufacture of plastic fibers, antioxidants, dyestuff intermediates,
corrosion preventatives, and special polymers. Purified MDA is
used in manufacturing epoxy resin curing agents, wire coating
applications, polyurethane co-reactants, pigments and dyes, and
defense applications.
U.S. production of MDA totaled approximately 600 million pounds
per year in 1986. According to 1985-1986 figures, 3,836 workers
were potentially exposed in 11 sectors of industry with an additional
189 maintenance workers in these areas as well.3
The following sections discuss the MDA standard as it pertains to
general industry. OSHA also has developed a separate booklet
that discusses the MDA standard's application to the construction
industry.
Scope and Application
This publication discusses OSHA's standard (29 CFR 191 0.1050)
as it applies to all occupational exposures to MDA in general
industry where it is produced, released, stored, handled, used, or
transported. Exceptions include --
- the processing, using, and handling of MDA products where
initial monitoring or objective data indicate the product is not
capable of releasing MDA in excess of the action level under
expected conditions, and where no dermal exposure can occur; 4
- the storing, transporting, distributing, or selling of MDA in intact
containers sealed to contain MDA dusts, vapors, or liquids;
- materials in any form that contain less than 0.1 percent MDA
by weight or volume; and
- finished articles containing MDA.
Provisions of the Standard
Permissible Exposure Limit
Time-Weighted Average and Short-Term Exposure Limit
The employer must ensure that no employee is exposed to MDA
above the permissible exposure limit (PEL) of 10 parts per billion
(ppb) as an 8-hour time-weighted average (TWA) or a short-term
exposure limit (STEL) of 100 ppb averaged over a 15-minute
sampling period.
Action Level
The action level for a concentration of airborne MDA is 5 ppb as an
8-hour TWA. Employers must begin compliance activities such as
exposure monitoring, medical surveillance, or temporary removal
as soon as the action level is reached or exceeded.
Regulated Areas
The employer must establish regulated areas where airborne
concentrations of MDA exceed or may reasonably be expected to
exceed the PEL and where employees handle or use non-airborne
MDA liquids or mixtures. Regulated areas must be demarcated
from the rest of the workplace so that potential exposure is limited.
Only authorized personnel may enter regulated areas. All persons
who enter must be supplied with, and required to use, personal
protective equipment and clothing. No eating, drinking, smoking,
chewing of tobacco or gum, or applying of cosmetics is permitted
in regulated areas.
Warning signs must be posted in each regulated area and at all
entrances or accessways to the areas. These signs must bear the
following information:
Labels and Signs
The employer must ensure that labels or other appropriate forms of
warning are provided for containers of MDA anywhere in the
workplace. The labels shall comply with the requirements of
OSHA's Hazard Communication Standard, 29 CFR 1910.1200(f)5
and include the following legends:
Labels for containers of Pure MDA must contain the following
information:
Warning labels for containers of Mixtures containing MDA must
include the following information:
Exposure Monitoring and Medical Surveillance
Each employer who has a workplace or worksite covered by this
standard must perform initial monitoring for all employees who are,
or may reasonably be expected to be, exposed to airborne concentrations
of MDA at or above the action level. If the required initial
monitoring reveals employee exposure at or above the action level,
but at or below the PEL, the employer must repeat monitoring at
least every 6 months. If exposure is above the PEL, the employer
must repeat monitoring at least every 3 months. If initial monitoring
reveals employee exposure to be below the action level, the
employer may discontinue the monitoring for those employees
whose exposures are represented by such monitoring.
The employer must reinitiate monitoring when there has been a
change in production process, chemicals, control equipment,
personnel, or work practices that may result in new or additional
exposures to MDA or when there is any reason to suspect a
change that may result in new or additional exposures.
Routine inspections of employee dermal areas (hands, face,
forearms) potentially exposed to MDA must be performed by the
employer. Other potential dermal exposure must be referred to
medical personnel for observation. If the employer determines an
employee has been exposed to MDA, the employer must locate
the source, implement protective measures for correction, and
maintain records of corrective actions.
Employees must be notified in writing, either individually or by
posting of results in an accessible location, within 15 days after the
receipt of results of any monitoring performed. The written notification
must contain corrective action being taken to reduce employee
exposure to or below the PEL, whenever the PEL is exceeded.
The employer also must institute a medical surveillance program
for employees who --
- are exposed to MDA at or above the action level for 30 or more
days per year;
- are subject to dermal exposure for 15 or more days per year;
- are exposed in emergency situations; and
- the employer has reason to believe are being dermally exposed or
who show signs or symptoms of MDA exposure.
Each employee must receive an initial medical exam within 150
days of the effective date of this standard or before the time of
initial assignment. The physical exam must include all routine
exam parameters and exams for signs of liver disease and skin
exposure. Lab tests must include liver function tests and urinalysis
as well as additional tests necessary in the opinion of the physician.
All medical exams and procedures must be performed by or under
the supervision of a licensed physician, provided at no cost to the
employee, and given at a reasonable time and place. Follow-up
medical exams must be provided at least annually after the initial
exam. Also, if an employee is exposed to a potentially hazardous
amount of MDA in an emergency situation, the employer must
provide a medical exam at that time.
The employer must provide the examining physician the following
information:
- a copy of the OSHA MDA regulation and its appendices;
- a description of the affected employee's duties as related to
potential exposure to MDA;
- the current actual or representative MDA exposure level;
- a description of personal protective equipment currently in use
or recommended; and
- information from previous employment-related medical exams.
The employer must provide a written copy of the examining
physician's opinion to the affected employee within 15 days of
receipt. The report should include --
- occupationally pertinent results of the exam and test;
the physician's opinion on detected medical conditions that
would place the employee at an increased risk of material
impairment of health from exposure to MDA;
- physician recommended limits upon the employee's exposure
to MDA or upon use of personal protective equipment and
clothing and respirators; and
- a statement that the employee has been informed by the
physician of results of the medical exam and medical conditions
resulting from MDA exposure, which require further
explanation or treatment.
The physician, however, is not to reveal in the written opinion given
to the employer any specific findings or diagnoses unrelated to
occupational exposure to MDA.
Methods of Compliance
Compliance Program
A written compliance program must be established and implemented to
reduce employee exposure to the PEL or below by the
use of engineering and work practice controls and by the use of
respiratory protection where permitted. The plan must include a
schedule for periodic maintenance and a written plan for emergency
situations. The emergency plan must specifically provide
that employees engaged in correcting emergency conditions be
equipped with the appropriate required personal protective equipment
and clothing until the emergency is abated. A provision for
alerting and evacuating affected employees also must be included.
Employees who face potential exposure (direct and indirect) to
MDA must be alerted promptly. Those employees not engaged in
correcting the emergency must be evacuated immediately.
The written plans must be reviewed at least once every 12 months
to ensure they reflect the current status of the program.
The written compliance program must be made available for
examination and copying to the Assistant Secretary for OSHA, the
Director of the National Institute for Occupational Safety and
Health (NIOSH), and affected employees and their designated
representatives, upon request.
Control Measures
Engineering and work practice controls are the primary methods
used to reduce occupational exposure to MDA. Engineering
controls and work practices must be instituted to reduce and
maintain employee exposure to MDA at or below the PEL except
when the employer can establish that these controls are not
feasible.
Engineering controls reduce employee exposure in the workplace
either by removing or isolating the hazard or isolating the worker
from exposure. Local exhaust ventilation, general ventilation
systems, and special isolation devices or enclosures are examples
of engineering controls. Engineering controls must be examined
and maintained, or replaced, on a scheduled basis. In circumstances
where engineering controls alone do not reduce MDA
exposure to the PEL, however, respiratory protection must be used
as well.
Proper work practice controls reduce the likelihood of exposure by
altering the manner in which a task is performed. Safe work
practices required under the MDA standard include, but are not
limited to, maintaining separate hygiene facilities (i.e., lunchrooms,
change areas, and shower facilities) and requiring proper housekeeping
practices (visual inspection program, clean-up methods,
waste removal practices).
Under the MDA standard, the administrative control of temporary
removal may be instituted to remove the worker from the hazard in
the workplace, when appropriate. Worker rotation, however,
cannot be used to reduce exposures to MDA.
Respiratory Protection
Where feasible engineering controls and work practices are not
sufficient to reduce MDA exposure to the PEL or below, the
employer must use them to reduce employee exposure to the
lowest achievable levels and supplement them through the use of
respirators.
Respirators must be used in the following circumstances:
- while feasible engineering and work practice controls are being
installed or implemented;
- in work operations for which engineering and work practice
controls are not feasible;
- in work situations where feasible engineering and work practice
controls are not yet sufficient to reduce exposure to or
below the PEL; and
- in emergencies.
Respirators must be selected from among those approved by the
Mine Safety and Health Administration (MSHA) and NIOSH.
Where respiratory protection is required, the employer must
develop a respiratory protection program. Respirators and the
respiratory protection program must be provided at no cost to the
employee.
If employees cannot wear negative-pressure respirators, they must
be given the option of wearing a positive-pressure respirator or a
supplied-air respirator operated in continuous flow or pressure
demand mode. Where air-purifying respirators are used, the air-purifying
element must be replaced as needed, to maintain effectiveness.
Respirator fit testing must be performed and the results
recorded at the time of initial fitting and at least annually thereafter
for negative-pressure respirators.
Hygiene Facilities and Practices
Employees required to work in regulated areas must be provided
clean change rooms, shower facilities, and lunchrooms. Separate
storage of personal protective equipment and clothing and street
clothes must be maintained.
Employees must shower at the end of a work shift and may not
leave the worksite wearing any protective equipment or clothing
worn during the work shift. Where dermai exposure to MDA
occurs, materials spilled on the skin must be removed as soon as
possible by methods that do not facilitate the dermai absorption of
MDA.
Separate lunchroom facilities located within the workplace and in
areas of potential airborne exposure to MDA must have a positive-pressure,
temperature controlled, filtered air supply. Lunch areas
may not be located in areas within the workplace where the
potential of dermal exposure to MDA exists.
Employees must wash their hands and faces prior to eating,
drinking, smoking, or applying cosmetics. No employees may
enter the lunchroom with protective equipment or clothing.
Housekeeping
All surfaces must be maintained as free as possible of accumulations of
MDA. A regular visual inspection program must be instituted
to detect MDA leaks, spills, or discharges. All leaks must be
repaired, and liquid or dust spills promptly cleaned. Compressed
air may not be used to clean contaminated surfaces. Shoveling,
dry sweeping, and other methods of dry clean-up maybe used
where HEPA6 -filtered vacuuming and/or wet cleaning are not
feasible or practical. All waste, scrap, debris, bags, containers,
equipment, or clothing contaminated with MDA must be collected
and disposed of in a way that prevents re-entry of MDA into the
workplace.
Temporary Removal
An employee must be removed from work environments in which
exposure to MDA is at or above the action level or where dermal
exposure to MDA may occur following an initial exam, periodic
exams, an emergency situation, or an additional examination when
- the employee exhibits signs and/or symptoms indicative of
acute exposure to MDA; or
- the examining physician determines that an employee's
abnormal liver function tests are not associated with MDA
exposure but that the abnormalities may be exacerbated as a
result of occupational exposure to MDA.
Following a final medical determination that the employee has a
detected medical condition that increases the risk of material
impairment of health from MDA exposure, the employer must
remove the employee from work environments in which exposure
to MDA is at or above the action level or where dermal exposure to
MDA may occur.
Employees may return to former job status
- when they no longer show signs or symptoms of exposure to
MDA;
- upon the advice of the physician; or
- when a subsequent final medical determination results in a
medical finding" that employees no longer have a detected
medical condition that puts them at risk.
Personal Protective Equipment and Clothing
The employer must provide, at no cost to the employee, and
ensure use of personal protective equipment and clothing to
prevent contact with MDA where:
- employees are subject to dermal exposure to MDA;
- liquids containing MDA can be splashed into the eyes; and
- airborne concentrations of MDA are in excess of the PEL.
Recommended personal protective equipment and clothing
includes, but is not limited to aprons, coveralls or full-body work
clothing, gloves, head and foot coverings, face shields, and
splashproof safety goggles.
Employees must remove MDA-contaminated protective equipment
and clothing in change rooms at the end of the work shift. Contaminated
work clothing or equipment must be stored in closed
labeled containers. Only authorized employees may take contaminated
equipment or clothing out of change rooms for laundering,
maintenance, or disposal.
The employer must ensure that personal protective equipment and
clothing is laundered, cleaned, repaired, or replaced to maintain its
effectiveness. Contaminated clothing must be transported in
properly labeled, sealed, impermeable bags or containers. Any
person who launders or cleans MDA-contaminated clothing or
equipment must be informed of the potentially harmful effects of
exposure. The employer also must make known that removal of
MDA by blowing or shaking is prohibited.
Recordkeeping
The employer must establish and maintain an accurate record of
all monitoring data as well as objective data used to demonstrate
that the processing, use, or handling of products is exempt from
requirements of the standard for initial monitoring.
The employer must keep for 30 years an accurate record of all
measurements taken to monitor employees' exposure to MDA.
This record must include:
- the date of measurement, number, duration, and results of
each sample taken, including a description of the procedure
used to determine representative employee exposures;
- identification of the sampling and analytical methods used;
a description of the type of respiratory protective devices worn;
and
- the name, social security number, job classification, and
exposure levels for each employee monitored and all other
employees whose exposure measurement it represents.
The employer must maintain an accurate record for each
employee subject to medical surveillance. The record must
include:
- the name, social security number, and description of duties;
- a copy of the examining physician's written opinion on initial,
periodic, or special exams -- including results of medical exams
and all tests, opinions, and recommendations;
- results of airborne exposure monitoring done for the employee
and the representative exposure levels supplied to the physician;
and
- any employee medical complaints related to exposure to MDA.
All required, maintained records must be made available, upon
request, to the OSHA Assistant Secretary and the Director of
NIOSH in accordance with Access to Employee Exposure and
Medical Records, 29 CFR 1910.20.
If the employer ceases to do business and there is no successor to
receive the records, the employer must notify the Director of
NIOSH, at least 90 days prior to termination, and transmit the
records to the Director within that period.
Training and Information
In addition to the warning signs and labels required in regulated
areas and on MDA containers, employers must provide material
safety data sheets (MSDSs) and training and written information
on MDA. MSDSS must comply with OSHA's Hazard Communication
Standard, 29 CFR 1910.1200.
Also, the employer must develop a training program for all
employees exposed to airborne concentrations of MDA in accordance
with provisions of the Hazard Communication Standard.
Training must be provided at the time of initial assignment and at
least annually thereafter.
The content of the training program is intended to inform
employees of
- the hazards to which they are exposed;
- the necessary steps to protect themselves, including those to
be taken during emergency situations;
- limitations and the proper use of respirators and protective
equipment;
- a description of medical examinations and their purpose; and
- implementation of work practices and the use of available
engineering controls.
The employer also must
- provide an explanation of the contents of the MDA standard
and where a copy is available;
- describe the required medical surveillance program; and
- describe the medical removal provision.
All training materials, including a copy of the MDA standard, must
be available in writing to all employees without cost and to the
Assistant Secretary of OSHA and the Director of NIOSH, upon
request.
Other Sources of OSHA Assistance
Safety and Health Management Guidelines
Effective management of worker safety and health protection is a
decisive factor in reducing the extent and severity of work-related
injuries and illnesses and their related costs. To assist employers
and employees in developing effective safety and health programs,
OSHA published recommended Safety and Health Management
Guidelines (January 26, 1989, 54 FR: 3908-3916). These voluntary
guidelines apply to all places of employment covered by
OSHA.
The guidelines identify four general elements that are critical to the
development of a successful safety and health management
program:
- management commitment and employee involvement,
- worksite analysis,
- hazard prevention and control, and
- safety and health training.
The guidelines recommend specific actions, under each of these
general elements, to achieve an effective safety and health program.
State Programs
The Occupational Safety and Health Act of 1970 encourages
states to develop and operate their own job safety and health
plans. OSHA approves and monitors these plans. There are
currently 25 state plan states; 23 of these states administer plans
covering both private and public (state and local government)
employment; the other 2 states, Connecticut and New York, cover
the public sector only.
The 25 states and territories with their own OSHA-approved
occupational safety and health plans must adopt standards identical
to, or at least as effective as, the federal standards. Until a
state standard is promulgated, OSHA will provide interim enforcement
assistance, as appropriate, in these states. A listing of states
with approved plans appears at the end of this booklet.
Consultation Services
Consultation assistance is available on request to employers who
want help in establishing and maintaining a safe and healthful
workplace. Largely funded by OSHA, the service is provided at no
cost to the employer. Primarily developed for smaller employers
with more hazardous operations, the consultation service is
delivered by state government agencies or universities employing
professional safety consultants and health consultants. Comprehensive
assistance includes an appraisal of all mechanical,
physical work practices, and environmental hazards of the work-place
and all aspects of the employer's present job safety and
health program. No penalties are proposed or citations issued for
hazards identified by the consultant.
For more information concerning consultation assistance, see the
list of consultation projects listed at the end of this publication.
Voluntary Protection Programs (VPPs)
Voluntary protection programs and onsite consultation services,
when coupled with an effective enforcement program, expand
worker protection to help meet the goals of the OSH Act. The
three VPPs -- Star, Merit, and Demonstration -- are designed to
recognize outstanding achievement by companies that have
successfully incorporated comprehensive safety and health
programs into their total management system. They motivate
others to achieve excellent safety and health results in the same
outstanding way as they establish a cooperative relationship
between employers, employees, and OSHA.
For additional information on VPPS and how to apply, contact the
OSHA national, regional, or area offices listed at the end of this
publication.
Training and Education
OSHA's area offices offer a variety of informational services, such
as publications, audiovisual aids, technical advice, and speakers
for special engagements. OSHA's Training Institute in Des
Plaines, IL, provides basic and advanced courses in safety and
health for federal and state compliance officers, state consultants,
federal agency personnel, and private sector employers,
employees, and their representatives.
OSHA also provides funds to nonprofit organizations, through
grants, to conduct workplace training and education in subjects
where OSHA believes there is a lack of workplace training. Grants
are awarded annually, with a 1-year renewal possible. Grant
recipients are expected to contribute 20 percent of the total grant
cost.
For more information on grants, training and education, contact the
OSHA Training Institute, Office of Training and Education, 1555
Times Drive, Des Plaines, IL 60018, (708) 297-4810.
For further information on any OSHA program, contact your
nearest OSHA regional or area office listed at the end of this
publication.

OSHA Consultation Project Directory
Consultation programs provide free services to employers who
request help in identifying and correcting specific hazards, want to
improve their safety and health programs, and/or need further
assistance in training and education. Funded by OSHA and
delivered by well-trained professional staff of state governments,
consultation services are comprehensive, and include an appraisal
of all workplace hazards, practices, and job safety and health
programs; conferences and agreements with management;
assistance in implementing recommendations; and a follow-up
appraisal to ensure that any required corrections are made. For
more information on consultation programs, contact the appropriate
office in your state listed below.
