## 4. FIRST AID MEASURES

Eye Con tact In case of contact with substance, immediately flush skin or eyes with running water for at

least 20 minutes. Get medical attention.

Skin Contact In case of contact with substance, immediately flush skin or eyes with running water for at

least 20 minutes. Get medical attention. Wash off immediately with soap and plenty of

water removing all contaminated clothes and shoes. Seek medical attention immediately.

Inhalation Inhalation may cause irritation of the upper respiratory tract. Symptoms of overexposure

may include fatigue, confusion, headache, dizziness and drowsiness. Move victim to fresh

air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is

difficult. Get medical attention immediately.

Ingestion Swallowing may cause abdominal spasms and other symptoms that parallel over

- exposure

from inhalation. Aspiration of material into the lungs can cause chemical pneumonitis. Call

a physician or Poison Control Center immediately. Do NOT induce vomiting.

Protection of Medical First

Responders Ensure that medical personnel are aware of the material(s) involved, take precautions to

protect themselves and prevent spread of contamination. Provide this Material Safety Data

Sheet to the attending Physician.

Products Harmful vapors can include carbon monoxide, carbon dioxides, carbon oxides and nitrogen

oxides (NOx).

Explosion D ata Sensitivity to

Mechanical Impact Sensitivity to

Static Discharge In the event of fire and/or explosion do not breathe fumes. Use water to spray to cool

unopened containers.

Specific Hazards Arising from

the Chemical Can be ignited easily and burns vigorously. Vapor from the solvent may accumulate in

container headspace resulting in flammability hazard.

. ACCIDENTAL RELEASE M EASURES

Personal Precautions Do not touch or walk through spilled material. Stop leak if you can do it without risk. Avoid

contact with skin, eyes and clothing. Use personal protective equipment.

Environmental Precautions Prevent entry into wat erways, sewers, basements or confined areas. Refer to protective

measures listed in Sections 7 and 8.

Methods for Containment Prevent further leakage or spillage if safe to do so.

Methods for Cleaning Up Small Spills

— Recommend use of alcohol s to clean spills or machinery. Dispose of rags and

wipes as hazardous waste per RCRA landfill or incineration.

Large Spills

— Ventilate area well. Cover liquid spill with inert absorbent material. Sweep or

scoop up and transfer to properly labeled con tainers. Clean contaminated surface

thoroughly using alcohol wipes. Dispose of rags and wipes as hazardous waste per RCRA

landfill or incineration.

Personal Protective Equipment

Eye/Face Protection Safety g lasses with side

- shields.

Skin and Body Protection Long sleeved clothing. Chemical resistant apron. Impervious gloves f or any handling

steps where this material is part of a carrier liquid/solvent other than the aqueous

suspension not ed in the section 3 description above, gloves comprised of material that

successfully passes ASTM F

- 739 testing (continuous liquid contact method) must be used.

Glove must be changed before the breakthrough time for the carrier liquid (as dete rmined by

the ASTM F

- 739 testing or by the manufacturer.)

Respiratory Protection The Environmental Protection Agency requires the minimum respiratory protection to be a

full face

- piece air purifying respirator with high efficiency parti culate air filter P100 (or

N100/R100) cartridges whenever there is a potential exposure to particulate/aerosol

containing this material. If exposure limits are exceeded or irritation is experienced,

NIOSH/MSHA approved respiratory protec tion should be worn. Respiratory

protection must be provided in accordance with current local regulations.

Hygiene Measures Handle in accordance with good industrial hygiene and safety practice. Remove and wash

contaminated clothing bef ore re

- use. Provide regular cleaning of equipment, work area and

clothing. Wash hands before breaks and immediately after handling the product. Keep

away from food, drink and animal feeding stuffs.

. TOXICOLOGICAL INFORMATION

Acute Toxicity

– Engineering Sample.

Established exposure values do not address the small size of particles found in this product and my not provide adequate

protection against occupational exposure.

TOLUENE: Case studies of persons abusing toluene suggest isolated incidences of adverse effects on the fetus including birth

defects. Abuse of toluene at high concentrations (e.g., glue sniffing and solvent abuse) has been associated with adverse effects

on the liver, kidney and nervous system, and can cause CNS depression, cardiac arrhythmias, and death. Studies of workers

indicate long term exposure may be related to impaired color vision and hearing. Some studies of workers suggest long term

exposure may be related to neurobehavioral and cognitive changes. Some of these effects have been observed in laboratory

animals following repeated exposure to high levels of toluene. Several studies of workers suggest long term exposure may be

related to small increases in spontaneous abortions and changes in some gonadotropic hormones. However, the weight of

evidence does not indicate toluene is a reproductive hazard to humans. Studies in laboratory animals indicate some changes in

reproductive organs following high levels of exposure, but no significant effects on mating performance or reproduction were

observed. Case studies of persons abu sing toluene suggest isolated incidences of adverse effects on the fetus including birth

defects. Findings in laboratory animals have been largely negative. Positive findings include small increases in minor skeletal

and visceral malformations and dev elopmental delays following very high levels of maternal exposure. Studies of workers

indicate long

- term exposure may be related to effects on the liver, kidney and blood, but these appear to be limited to changes in

serum enzymes and decreased leukocy te counts. Adverse effects on the liver, kidney, thymus and nervous system were

observed in animal studies following very high levels of exposure. The relevance of these findings to humans is not clear at this

time.
