Current through Register 2024 Notice Reg. No. 28, July 12, 2024
I. Substance Identification
A. Synonyms and trade names; DBCP;
						  Dibromochloropropane; Fumazone (Dow Chemical Company TM); Nemafume; Nemagon
						  (Shell Chemical Co. TM); Nemaset; BBC 12; and OS 1879.
B. Permissible exposure:
1. Airborne. 1 part DBCP vapor per billion parts of air
						  (1 ppb); time-weighted average (TWA) for an 8-hour workday.
2. Dermal. Eye contact and skin contact with DBCP are
						  prohibited.
C. Appearance and odor: Technical grade DBCP is a dense
						  yellow or amber liquid with a pungent odor. It may also appear in granular
						  form, or blended in varying concentrations with other liquids.
D. Uses: DBCP is used to control nematodes, very small
						  worm-like plant parasites, on crops including cotton, soybeans, fruits, nuts,
						  vegetables and ornamentals.
II. Health Hazard Data
A. Routes of entry: Employees may be exposed:
1. Through inhalation (breathing);
2. Through ingestion (swallowing);
3. Skin contact; and
4. Eye contact.
B. Effects of exposure:
1. Acute exposure. DBCP may cause drowsiness,
						  irritation of the eyes, nose, throat and skin, nausea and vomiting. In
						  addition, overexposure may cause damage to the lungs, liver or kidneys.
2. Chronic exposure. Prolonged or repeated exposure to
						  DBCP has been shown to cause sterility in humans. It also has been shown to
						  produce cancer and sterility in laboratory animals and has been determined to
						  constitute an increased risk of cancer in man.
3. Reporting signs and symptoms. If you develop any of
						  the above signs or symptoms that you think are caused by exposure to DBCP, you
						  should inform your employer.
III. Emergency First Aid Procedures
A. Eye exposure. If DBCP liquid or dust containing DBCP
						  gets into your eyes, wash your eyes immediately with large amounts of water,
						  lifting the lower and upper lids occasionally. Get medical attention
						  immediately. Contact lenses should not be worn when working with DBCP.
B. Skin exposure. If DBCP liquids or dusts containing
						  DBCP get on your skin, immediately wash using soap or mild detergent and water.
						  If DBCP liquids or dusts containing DBCP penetrate through your clothing,
						  remove the clothing immediately and wash. If irritation is present after
						  washing get medical attention.
C. Breathing. If you or any person breathe in large
						  amounts of DBCP, move the exposed person to fresh air at once. If breathing has
						  stopped, perform artificial respiration. Do not use mouth-to-mouth. Keep the
						  affected person warm and at rest. Get medical attention as soon as
						  possible.
D. Swallowing. When DBCP has been swallowed and the
						  person is conscious, give the person large amounts of water immediately. After
						  the water has been swallowed, try to get the person to vomit by having him
						  touch the back of his throat with his finger. Do not make an unconscious person
						  vomit. Get medical attention immediately.
E. Rescue. Notify someone. Put into effect the
						  established emergency rescue procedures. Know the locations of the emergency
						  rescue equipment before the need arises.
IV. Respirators and Protective Clothing
A. Respirators. You may be required to wear a
						  respirator in emergencies and while your employer is in the process of reducing
						  DBCP exposures through engineering controls. If respirators are worn, they must
						  have a National Institute for Occupational Safety and Health (NIOSH) approval
						  label. (Older respirators may have a Bureau of Mines Approval label). For
						  effective protection, a respirator must fit your face and head snugly. The
						  respirator should not be loosened or removed in work situations where its use
						  is required. DBCP does not have a detectable odor except at 1,000 times or more
						  above the permissible exposure limit. If you can smell DBCP while wearing a
						  respirator, the respirator is not working correctly; go immediately to fresh
						  air. If you experience difficulty breathing while wearing a respirator, tell
						  your employer.
B. Protective clothing. When working with DBCP you must
						  wear for your protection impermeable work clothing provided by your employer.
						  (Standard rubber and neoprene protective clothing do not offer adequate
						  protection).
DBCP must never be allowed to remain on the skin.
						  Clothing and shoes must not be allowed to become contaminated with DBCP, and if
						  they do, they must be promptly removed and not worn again until completely free
						  of DBCP. Turn in impermeable clothing that has developed leaks for repair or
						  replacement.
C. Eye protection. You must wear splash-proof safety
						  goggles where there is any possibility of DBCP liquid or dust contacting your
						  eyes.
V. Precautions For Safe Use, Handling, and
						  Storage
A. DBCP must be stored in tightly closed containers in
						  a cool, well-ventilated area.
B. If your work clothing may have become contaminated
						  with DBCP, or liquids or dusts containing DBCP, you must change into
						  uncontaminated clothing before leaving the work premises.
C. You must promptly remove any protective clothing
						  that becomes contaminated with DBCP. This clothing must not be reworn until the
						  DBCP is removed from the clothing.
D. If your skin becomes contaminated with DBCP, you
						  must immediately and thoroughly wash or shower with soap or mild detergent and
						  water to remove any DBCP from your skin.
E. You must not keep food, beverages, cosmetics, or
						  smoking materials, nor eat or smoke, in regulated areas.
F. If you work in a regulated area, you must wash your
						  hands thoroughly with soap or mild detergent and water, before eating, smoking
						  or using toilet facilities.
G. If you work in a regulated area, you must remove any
						  impermeable protective equipment or clothing before leaving the regulated
						  area.
H. Ask your supervisor where DBCP is used in your work
						  area and for any additional safety and health rules.
VI. Access to Information
A. Each year, your employer is required to inform you
						  of the information contained in this Substance Safety Data Sheet for DBCP. In
						  addition, your employer must instruct you in the safe use of protective
						  equipment.
B. Your employer is required to determine whether you
						  are being exposed to DBCP. You or your representative have the right to observe
						  employee exposure measurements and to record the result obtained. Your employer
						  is required to inform you of your exposure. If your employer determines that
						  you are being overexposed, he is required to inform you of the actions which
						  are being taken to reduce your exposure.
C. Your employer is required to keep records of your
						  exposure and medical examinations. Your employer is required to keep exposure
						  and medical data for at least 40 years or the duration of your employment plus
						  20 years, whichever is longer.
D. Your employer is required to release exposure and
						  medical records to you, your physician, or other individual designated by you
						  upon your written request.
VII. Transportation of DBCP
A. As a vehicle operator transporting DBCP, you are
						  entitled to be given and allowed to keep a copy of this Substance Safety Data
						  Sheet for DBCP.
B. All provisions of this substance data sheet except
						  Section VI apply to the safe handling of DBCP by vehicle operators.
C. Any spill or leak of DBCP or anytime DBCP can be
						  smelled, it is to be considered an emergency. Under these circumstances, get
						  fresh air. Only adequately trained persons with appropriate respiratory
						  protective equipment and protective clothing shall be permitted to approach the
						  vehicle.
