8. HEALTH HAZARD DATA
-----------------------------------------------------------------------------

EYE CONTACT:
Mild Eye Irritation: signs/symptoms can include redness, swelling,
pain, and tearing.

SKIN CONTACT:
Moderate Skin Irritation (after prolonged or repeated contact):
signs/symptoms can include redness, swelling, itching, and dryness.

INHALATION:
Central Nervous System Depression: signs/symptoms can include
headache, dizziness, drowsiness, incoordination, slowed reaction time,
slurred speech, giddiness and unconsciousness.

Irritation (upper respiratory): signs/symptoms can include soreness
of the nose and throat, coughing and sneezing.

Prolonged or repeated exposure may cause:

Blood disorders: signs/symptoms can include prolonged weakness
and fatigue.

Bone Marrow Depression: signs/symptoms can include prolonged
weakness and fatigue.

Heart Effects: signs/symptoms can include arrhythmia, heart
attack and death.

Immune System Impairment (immunosuppression): signs/symptoms can
include inability to fight infections.

Kidney Effects: signs/symptoms can include reduced urine volume,
blood in urine and back pain.

Liver Effects: signs/symptoms can include yellow skin(jaundice)
and tenderness of upper abdomen.

Nervous System Effects: signs/symptoms can include emotional
changes, lack of coordination, tremors and sensory loss.

Lung Damage: signs/symptoms can include coughing, difficulty
breathing, wheezing, tightness in chest, congestion, and
coughing up of blood.

N-METHYL ACETAMIDE (N-MA) is formed during curing. Prolonged
overexposure to N-MA vapors caused adverse reproductive effects in
lab animals.

FORMALDEHYDE vapors may form if the product is heated above 150
degrees C. Formaldehyde is a known skin and respiratory sensitizer,
an eye, skin and respiratory system irritant, and a potential cancer
