SECTION 3. HAZARDS IDENTIFICATION
***EMERGENCY OVERVIEW***
WARNING! CAUSES EYE AND SKIN IRRITATION. HARMFUL IF
SWALLOWED. OXIDIZER.
Potential Health Effects
Acute Effects (Short Term):
Eye: Contact with paste may result in irritation, redness, tearing, and
blurred vision.
MATERIAL SAFETY DATA SHEET
Date Prepared: 08/20/03 Page: 2
Cream Hardener MSDS Number: 120001
Skin: May cause skin irritation. Prolonged or repeated contact may dry
the skin. Symptoms may include redness, burning, drying and
cracking of skin, and skin burns.
Swallowing: Ingestion of this material may cause gastrointestinal irritation,
nausea, diarrhea, and vomiting. Aspiration of this material into the
lungs due to vomiting may produce chemical pneumonitis which
can be fatal. If vomiting occurs spontaneously, keep head below
hips to prevent aspiration of liquid into lungs.
Inhalation: Not expected to be an inhalation hazard.
Chronic Effects of Overexposure (Long Term):
Benzoyl Peroxide: Repeated or prolonged contact may cause skin
sensitization. Overexposure to this material has been known to
cause the following effects in lab animals: skin damage. Benzoyl
Peroxide has caused tumorigenic effects in laboratory animals.
Cancer Information: This product does not contain any substance, which is
listed as a carcinogen by NTP, IARC or OSHA in quantities greater than
0.1%.
Primary Route(s) of Entry: Inhalation, Skin contact, Eye contact, Ingestion,
Skin absorption.
SECTION 4. FIRST AID MEASURES
Eyes: Flush eyes gently with water for at least 15 minutes. Seek medical
attention.
Skin: Immediately remove contaminated clothing. Wash exposed area
with soap and water. Seek medical attention. Launder clothing
before reuse.
Swallowing: Consult a physician or poison control center immediately. DO NOT
INDUCE VOMITING. If individual is drowsy or unconscious, do not
give anything by mouth; place individual on the left side with the
head down. If possible, do not leave individual unattended.
Inhalation: If symptoms develop, immediately move individual away from
exposure and into fresh air. Seek immediate medical attention;
keep person warm and quiet. If person is not breathing, begin
artificial respiration. If breathing is difficult, oxygen may be benificial
if administered by trained personnel.
SECTION 5. FIRE FIGHTING MEASURES
MATERIAL SAFETY DATA SHEET

Cream Hardener MSDS Number: 120001
Flash Point: 184 潞F (84 潞C)
Explosive Limit: Lower: N/D Upper: N/D
Autoignition Temperature: Not Determined
OSHA Flammability Class: Combustible Liquid 鈥? Class IIIA
Hazardous Products of Combustion: May form toxic and corrosive gases:
carbon dioxide, carbon monoxide, benzoic acid and various hydrocarbons.
Fire and Explosion Hazards: Fire hazard increases when material becomes
dry. Vapors are heavier than air and may travel along the ground or may
be moved by ventilation and ignited by pilot lights, other flames, sparks,
heaters, smoking, electric motors, static discharge, or other ignition
sources at locations distant from material handling point.
Extinguishing Media: Regular foam, carbon dioxide, dry chemical.
Fire Fighting Instructions: Fight fire like a fuel oil fire. Water may be used to
keep fire-exposed containers cool until fire is out. Wear a self-contained
breathing apparatus NIOSH approved with a full facepiece operated in the
positive pressure demand mode with appropriate turn-out gear and
chemical resistant personal protective equipment.
NFPA Rating: Health - 2, Flammability - 2, Reactivity - 2
SECTION 6. ACCIDENTAL RELEASE MEASURES
In Case of Spill: Eliminate all sources of ignition such as flares, flames (including
pilot lights), and electrical sparks. Ventilate the area. Wear proper protective
equipment (Section 8). Avoid breathing vapors. Collect with an inert absorbant
and dispose of properly.
SECTION 7. HANDLING AND STORAGE
Handling: All hazard precautions given in the data sheet must be observed. Avoid
contact with eyes, skin and clothing. Wash thoroughly after handling. Use only
with adequate ventilation. Do not breathe vapors or spray mist. Do not take
internally. Close container after each use. Keep out of reach of children.
Storage: Store material in a cool, well-ventilated area. For maximum product
quality, avoid prolonged storage at temperatures above 75掳F (25掳C). To prevent
possible decomposition, temperatures in the storage facility must not exceed
217掳F (103掳C). Do not use or store near heat, sparks, or open flame. Keep
container tightly closed. Avoid contact with incompatible materials.
SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
MATERIAL SAFETY DATA SHEET
Date Prepared: 08/20/03 Page: 4
Cream Hardener MSDS Number: 120001
Eye Protection: Chemical splash goggles in compliance with OSHA regulations are
recommended.
Skin Protection: Protective gloves and proper clothing should be worn to prevent
skin contact. Gloves should be made of neoprene or natural
rubber. A barrier cream may be used for additional skin protection.
To prevent repeated or prolonged skin contact, wear impervious
clothing and boots.
Respiratory Protection: Use a NIOSH approved respirator designed to remove
particulate matter and organic solvent vapors.
Engineering Controls: Provide sufficient mechanical (general and/or local exhaust)
ventilation to maintain exposure below acceptable limits.
Explosion-proof ventilation system is acceptable.
