Common Name: 1,2-Butylene Oxide
CAS Number: 106-88-7
DOT Number: None
Date: January 4, 1989
-----------------------------------------
HAZARD SUMMARY
* 1,2-Butylene Oxide can affect you when breathed in.
* Because this is a MUTAGEN, handle it as a possible cancer
causing substance WITH EXTREME CAUTION.
* 1,2-Butylene Oxide can cause irritation of the eyes, skin,
nose, throat and lungs causing coughing and/or shortness of
breath.
* Skin blistering can occur on prolonged or repeated contact.
* High exposure can cause you to become lightheaded or to pass
out.
IDENTIFICATION
1,2-Butylene Oxide is a watery white liquid. It is used as a
stabilizer and to make other chemicals such as gasoline additives.
REASON FOR CITATION
* 1,2-Butylene Oxide is on the Hazardous Substance List because
it is cited by DEP, NFPA and EPA.
* This chemical is on the Special Health Hazard Substance List
because it is a MUTAGEN and is FLAMMABLE.
* Definitions are attached.
HOW TO DETERMINE IF YOU ARE BEING EXPOSED
* Exposure to hazardous substances should be routinely
evaluated. This may include collecting personal and area air
samples. You can obtain copies of sampling results from your
employer. You have a legal right to this information under
OSHA 1910.20.
* If you think you are experiencing any work related health
problems, see a doctor trained to recognize occupational
diseases. Take this Fact Sheet with you.
WORKPLACE EXPOSURE LIMITS
No occupational exposure limits have been established for 1,2-
Butylene Oxide. This does not mean that this substance is not
harmful. Safe work practices should always be followed.
* 1,2-Butylene Oxide is a MUTAGEN. Mutagens may have a cancer
risk. All contact with this chemical should be reduced to the
lowest possible level.
WAYS OF REDUCING EXPOSURE
* Where possible, enclose operations and use local exhaust
ventilation at the site of chemical release. If local exhaust
ventilation or enclosure is not used, respirators should be
worn.
* Wear protective work clothing.
* Wash thoroughly immediately after exposure to 1,2-Butylene
Oxide and at the end of the workshift.
* Post hazard and warning information in the work area. In
addition, as part of an ongoing education and training effort,
communicate all information on the health and safety hazards
of 1,2-Butylene Oxide to potentially exposed workers.
This Fact Sheet is a summary source of information of all potential
and most severe health hazards that may result from exposure.
Duration of exposure, concentration of the substance and other
factors will affect your susceptibility to any of the potential
effects described below.
------------------------------------------
HEALTH HAZARD INFORMATION
Acute Health Effects
The following acute (short term) health effects may occur
immediately or shortly after exposure to 1,2-Butylene Oxide:
* Exposure to 1,2-Butylene Oxide can cause irritation of the
skin, eyes, nose, throat and lungs causing coughing and/or
shortness of breath.
* High exposure can cause you to become lightheaded or to pass
out.
Chronic Health Effects
The following chronic (long term) health effects can occur at some
time after exposure to 1,2-Butylene Oxide and can last for months
or years:
Cancer Hazard
* 1,2-Butylene Oxide causes MUTATIONS (genetic changes). Such
chemicals may have a cancer or reproductive risk.
* Many scientists believe there is no safe level of exposure to
a carcinogen. Such substances may also have the potential for
causing reproductive damage in humans.
Reproductive Hazard
* There is limited evidence that 1,2-Butylene Oxide may decrease
fertility in females.
Other Long Term Effects
* Prolonged or repeated contact can cause skin blistering.
MEDICAL
Medical Testing
There is no special test for this chemical. However, if illness
occurs or over exposure is suspected, medical attention is
recommended.
Any evaluation should include a careful history of past and present
symptoms with an exam. Medical tests that look for damage already
done are not a substitute for controlling exposure.
Request copies of your medical testing. You have a legal right to
this information under OSHA 1910.20.
WORKPLACE CONTROLS AND PRACTICES
Unless a less toxic chemical can be substituted for a hazardous
substance, ENGINEERING CONTROLS are the most effective way of
reducing exposure. The best protection is to enclose operations
and/or provide local exhaust ventilation at the site of chemical
release. Isolating operations can also reduce exposure. Using
respirators or protective equipment is less effective than the
controls mentioned above, but is sometimes necessary.
In evaluating the controls present in your workplace, consider: (1)
how hazardous the substance is, (2) how much of the substance is
released into the workplace and (3) whether harmful skin or eye
contact could occur. Special controls should be in place for highly
toxic chemicals or when significant skin, eye, or breathing
exposures are possible.
In addition, the following controls are recommended:
* Where possible, automatically pump liquid 1,2-Butylene Oxide
from drums or other storage containers to process containers.
* Before entering a confined space where 1,2-Butylene Oxide may
be present, check to make sure that an explosive concentration
does not exist.
Good WORK PRACTICES can help to reduce hazardous exposures. The
following work practices are recommended:
* Workers whose clothing has been contaminated by 1,2-Butylene
Oxide should change into clean clothing promptly.
* Contaminated work clothes should be laundered by individuals
who have been informed of the hazards of exposure to 1,2-
Butylene Oxide.
* Eye wash fountains should be provided in the immediate work
area for emergency use.
* If there is the possibility of skin exposure, emergency shower
facilities should be provided.
* On skin contact with 1,2-Butylene Oxide, immediately wash or
shower to remove the chemical. At the end of the workshift,
wash any areas of the body that may have contacted 1,2-
Butylene Oxide, whether or not known skin contact has
occurred.
* Do not eat, smoke, or drink where 1,2-Butylene Oxide is
handled, processed, or stored, since the chemical can be
swallowed. Wash hands carefully before eating or smoking.
PERSONAL PROTECTIVE EQUIPMENT
WORKPLACE CONTROLS ARE BETTER THAN PERSONAL PROTECTIVE EQUIPMENT.
However, for some jobs (such as outside work, confined space entry,
jobs done only once in a while, or jobs done while workplace
controls are being installed), personal protective equipment may be
appropriate.
The following recommendations are only guidelines and may not apply
to every situation.
Clothing
* Avoid skin contact with 1,2-Butylene Oxide. Wear protective
gloves and clothing. Safety equipment suppliers/ manufacturers
can provide recommendations on the most protective
glove/clothing material for your operation.
* All protective clothing (suits, gloves, footwear, headgear)
should be clean, available each day, and put on before work.
Eye Protection
* Wear splash proof chemical goggles when working with liquid
1,2-Butylene Oxide, unless full face piece respiratory
protection is worn.
Respiratory Protection
IMPROPER USE OF RESPIRATORS IS DANGEROUS. Such equipment should
only be used if the employer has a written program that takes into.
