POTENTIAL HEALTH EFFECTS

EYE:
Contact may cause eye irritation with symptoms of reddening, tearing,
stinging, and swelling. Possible permanent damage.

SKIN:
May cause allergic skin reaction. Dimethylaminoethanol is extremely
irritating to the skin. Direct contact with the skin is corrosive. Can
cause moderate skin irritation. Repeated skin contact may result in
sensitization.

INHALATION:
Avoid breathing vapors or mists. Prolonged or excessive inhalation may
cause respiratory tract irritation. Inhalation of high concentrations has
been known to produce respiratory difficulties, loss of coordination and
decreased motor activity in rats.
ER FOAM 902072-1 Winter MSDS Number: foam902072-1W February 27, 2006

(section 3 continued)

INGESTION:
Harmful if swallowed. Symptoms may include abdominal pain, nausea,
vomiting and diarrhea. Chronic ingestion may cause liver or kidney damage.

CHRONIC EFFECTS:
Repeated skin contact may result in sensitization. Repeated inhalation
has been known to produce effects on the eyes and nasal mucosa as well as
respiratory and olfactory lesions in experimental animals.

MISCELLANEOUS:
At levels above the recommended exposure limit, the fluorocarbon acts as a
weak narcotic. Acute overexposure causes tremors, confusion, irritation,
suffocation, and may result in cardiac sensitization.

4. FIRST AID MEASURES

EYE CONTACT FIRST AID:
After initial flushing, remove any contact lenses and continue flushing
for at least 15 minutes. Get medical attention.

SKIN CONTACT FIRST AID:
Remove and launder contaminated clothing and shoes before reuse. Wash
affected area immediately with large amounts of soap and water. Get
medical attention if irritation develops or persists.

INHALATION FIRST AID:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. Get immediate medical attention.

INGESTION FIRST AID:
If swallowed, do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person. Get
immediate medical attention.
