4. FIRST AID MEASURES
FIRST AID PROCEDURES
Move victim to fresh air.  Give artificial respiration ONLY if breathing has stopped.  Give 
cardiopulmonary resuscitation (CPR) if there is no breathing AND no pulse.  Obtain medical attention 
IMMEDIATELY.
Inhalation:
Start flushing while removing contaminated clothing. Wash affected areas thoroughly with soap and 
water. If irritation, redness, or a burning sensation develops and persists, obtain medical advice.
Skin Contact:
Immediately flush eyes with running water for a minimum of 20 minutes.  Hold eyelids open during 
flushing.  If irritation persists, repeat flushing.  Obtain medical attention IMMEDIATELY.
Eye Contact:
Do not attempt to give anything by mouth to an unconscious person. If victim is alert and not 
convulsing, rinse mouth out but do not swallow.  IMMEDIATELY contact local Poison Control Centre.  
Vomiting should only be induced under the direction of a physician or a poison control centre.  If 
spontaneous vomiting occurs, have victim lean forward with head down to avoid breathing in of vomitus, 
rinse mouth and administer more water.  IMMEDIATELY transport victim to an emergency facility.
Ingestion:
Treat symptomatically. Medical conditions that may be aggravated by exposure to this product include 
diseases of the skin, eyes or respiratory tract.
Note to Physicians:
Skin contact can cause irritation, especially under the finger nails (and other confined spaces such as 
under rings or watch bands). Prolonged and repeated contact may lead to dermatitis. May cause 
defatting, drying and cracking of the skin.
Skin Contact:
Not likely to be absorbed through the skin.
Skin Absorption:
Vapours from this product are irritating to the eyes. Splashes to the eye may cause irritation, redness 
and pain.
Eye Contact:
Ingestion is not a likely route of exposure.
Ingestion:
May cause irregular pulse, systemic effects and central nervous system (CNS) depression. CNS 
depression is characterized by headache, dizziness, drowsiness, nausea, vomiting and incoordination.  
Severe overexposures may lead to coma and possible death due to respiratory failure. (3)

6. ACCIDENTAL RELEASE MEASURES
Information in this section is for responding to spills, leaks or releases in order to prevent or minimize the adverse effects on persons, 
property and the environment.  There may be specific reporting requirements associated with spills, leaks or releases, which change from 
region to region.
In all cases of leak or spill contact vendor at Emergency Number shown on the front page of this MSDS. 
Wear respirator, protective clothing and gloves. Clean up immediately to eliminate slipping hazard.  Do 
not allow to enter sewers or watercourses. Spilled material may cause floors and contact surfaces to 
become slippery. Collect product for recovery or disposal.  For release to land, or storm water runoff, 
contain discharge by constructing dykes or applying inert absorbent;  for release to water, utilize 
damming and/or water diversion to minimize the spread of contamination.  Ventilate enclosed spaces.  
Notify applicable government authority if release is reportable or could adversely affect the environment.
Containment and Clean-Up 
Procedures:
7. HANDLING AND STORAGE
HANDLING
Use normal "good" industrial hygiene and housekeeping practices. Containers exposed to heat may be 
under internal pressure.  These should be cooled and carefully vented before opening.  A face shield 
and apron should be worn. Vent container frequently, and more often in warm weather, to relieve 
pressure.

See Section 8, "Engineering Controls".
Ventilation Requirements:
Use only with adequate ventilation and avoid breathing vapours and aerosols. Avoid contact with eyes, 
skin or clothing.  Wash thoroughly with soap and water after handling.  Wash contaminated clothing 
thoroughly before re-use. Do not use cutting or welding torches on empty drums that contained this 
material/product.
Other Precautions:
STORAGE
See below.
Storage Temperature (°C):

respirator if concentrations are higher or unknown.
If while wearing a respiratory protection, you can smell, taste or otherwise detect anything unusual, or in 
the case of a full facepiece respirator you experience eye irritation, leave the area immediately.  Check 
to make sure the respirator to face seal is still good.  If it is, replace the filter, cartridge or canister.  If 
the seal is no longer good, you may need a new respirator.  (4)

Butylene Oxide: Possibly carcinogenic to humans. (IARC-2B)
Carcinogenicity Data:
Although there is no direct evidence that exposure of people to 1-Bromopropane adversely affects 
reproduction or development, studies reviewed by the expert panel and more recent studies in rats 
show that exposure to 1-Bromopropane can adversely affect reproduction and development.  (7)
    The critical reproductive toxicity study in animals was a two-generation, inhalation study. It showed 
exposure of rats to 250 ppm or greater altered numerous reproductive endpoints in both females and 
males. These included decreased prostate weight, decreased sperm motility and percent normal sperm 
in males and decreased litter size, decreased numbers of implantation sites, increased ovarian follicular 
cysts, and increased estrous cycle length in females. The panel determined that no adverse 
reproductive effects were observed at an exposure concentration of 100 ppm.  (7)
Another recent study showed that female rats exposed 8 hours per day to 200, 400, or 800 ppm 1-BP 
for 7 to 12 weeks showed a significant, dose-dependent increase in the number of irregular estrous 
cycles, with extended diestrus at 400 ppm (Yamada et al., 2003).  Additionally, examination of the 
ovaries showed a dose-dependent reduction in the number of normal antral (or mature) follicles at 
doses of 200 and 400 ppm. This effect is consistent with reduced fertility and litter sizes reported in 
earlier studies.  Interestingly, the number of primordial follicles was not significantly reduced in any of 
the 1-Bromopropane exposure groups. The authors suggest that antral follicle counts may provide a 
more sensitive indicator of 1-Bromopropane-induced female reproductive dysfunction than other 
endpoints such as estrous length.  (7)
Reproductive Data:
This product produced negative results for mutagenicity (Ames Test).  (3)
Mutagenicity Data:
No adverse teratogenic effects are anticipated.
Teratogenicity Data:
None known.
Respiratory / Skin Sensitization 
Data:
None known.
Synergistic Materials:
Butylene Oxide: Cancers of the respiratory system have been observed in rats and mice exposed by 
inhalation. Negative results have been obtained in mice exposed by skin application.  The International 
Agency for Research on Cancer (IARC) has concluded that this chemical is possibly carcinogenic to 
humans (Group 2B).  (4)
When n-Propyl Bromide was tested for genetic toxicity, it tested negative for dominant lethal activity in 
rats at 400 mg/Kg/day.  This dose was given to male rats prior to breeding once weekly for eight 
successive weeks.  No difference in mating performance was observed.  (9)
The frequency of fertile matings, mean number of corpora lutea, number of implants per female, 
number of live embryos per female and the dominant lethal index was comparable to the negative 
control group at weeks 1 through 8 after treatment.  The frequency of dead implants was higher during 
week eight compared to the controls, but no increases in dominant lethal index were observed during 
the previous seven weeks.  The frequency of dead implants in the treated group was similar to that of 
the controls during weeks one through seven.  (9)
