EXTINGUSHING MEDIA AND FIRE FIGHTING INSTRUCTIONS
Use water spray, carbon dioxide or dry chemical to extinguish fires. Use water to keep containers
cool. Wear self-contained, positive pressure breathing apparatus.
6. ACCIDENTAL RELEASE MEASURES
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED
Where exposure level is not known, wear NIOSH approved, positive pressure, self-contained
respirator. Where exposure level is known, wear NIOSH approved, respirator suitable for level of
exposure. In addition to the protective clothing/equipment in Section 8 (Exposure Controls/Personal
Protection), wear impervious boots. Cover spills with some inert absorbent material; sweep up and
place in a waste disposal container. Flush area with water.
7. HANDLING AND STORAGE
Handling
Keep away from heat and flame. Avoid contact with eyes, skin and clothing. Wash thoroughly after
handling.
Storage
Areas containing this material should have fire safe practices and electric equipment in accordance
with applicable regulations and/or guidelines. Standards are primarily based on the material鈥檚
flashpoint, but mat also take into account properties such as miscibility with water or toxicity.
Storage temperature : not applicable
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS AND PERSONAL PROTECTIVE EQUIPMENT (PPE)
Engineering controls are not usually necessary if good hygiene practices are followed. Before eating,
drinking, or smoking, wash face and hands thoroughly with soap and water. Avoid unnecessary skin

contact. Impervious gloves and apron are recommended to prevent skin contact. For operations
where eye or face contact can occur, wear eye protection such as chemical splash-proof goggles or
face shield. Where exposures are below the Permissible Exposure Limit(PEL), no respiratory
protection is required. Where exposures exceed the PEL, use respirator approved by NIOSH for the
material and level of exposure.
It is recommended that a shower be taken after completion of workshift especially if significant
contact has occurred. Work clothing should then be laundered prior to reuse. Street clothing should
be stored separately from work clothing and protective equipment. Work clothing and shoes should
not be taken home.

11. TOXICOLOGICAL INFORMATION
Toxicological information for the product is found under Section 3.HAZARDS
IDENTIFICATION.
Toxicological information on the OSHA regulated components of this product is as follows:
Formaldehyde has oral(rat) and dermal(rabbit) LD50 values of 100mg/kg and 270 mg/kg,
respectively. The LC50 following a 4-hour inhalation exposure to rats is 250-478 ppm. Irritation of
the nose and throat has been observed in people exposed to formaldehyde vapor levels in excess of
1 ppm. Normal breathing may be seriously impaired at levels above 10 ppm and serious lung
damage can occur at levels exceeding 50 ppm. Formaldehyde has been reported to cause
pulmonary hypersensitivity in some individuals who were exposed to concentrations known to
cause irritation: however, no pulmonary sensitization has been demonstrated in laboratory animal
studies. Formaldehyde solutions can cause severe eye and moderate skin irritation. Repeated skin
exposure to solutions of 2% or more formaldehyde has caused allergic skin reactions.
Formaldehyde was found to be weakly mutagenic in a number of in vitro genotoxicity tests and
positive in certain in vivo screening tests for mutagenicity. Formaldehyde did not cause birth
defects in rats inhaling concentrations up to 10 ppm. However, a study using higher levels did
show a slight but statistically significant reduction in male fetal body weight. Lifetime inhalation
of formaldehyde vapor at concentrations above 5 ppm for 6 hours per day, caused nasal tumors in
laboratory animals. Epidemiology studies have failed to link cancer in humans with occupational
exposure to formaldehyde. Inhalation caused liver and kidney damage in laboratory animal tests.
Isobutanol has acute oral(rat) and dermal(rabbit) LD50 values of 2.46g/kg and 3.4g/kg,
respectively.
The LC50(rat) following a 4-hour inhalation exposure is >8000 ppm(24.24mg/L). Acute
overexposure to isobutanol vapor can cause irritation to the eyes(severe), skin(moderate), and
mucous membranes, as well as, central nervous system depression. Direct contact with isobutanol
may cause severe eye and mild to moderate skin irritation.
Xylene has an acute oral(rat) of 4.3 to 5g/kg and an acute 4-hour LC50(rat) of 19.7 to 29.1mg/L.
Inhalation of vapors may be irritating to the nose and throat. Skin contact results in moderate
irritation and loss of natural oils. Vapors cause eye irritation.

Ethylbenzene has acute oral(rat) and dermal(rabbit) LD50 values of 3500mg/kg and 5000mg/kg
respectively. The 4-hour inhalation LC50 in rat is 4000 ppm(17.36mg/L). It is a mild eye and skin
irritant. Prolonged exposure to the vapor of ethylbenzene may cause irritation of the eyes and
upper respiratory tract, motor ataxia, and hematological disorders and hepatobiliary complaints.
