COMPONENT HAZARD DATA
_________________________________________________________________
HAZARDOUS COMPONENT: %: CAS NO: EXPOSURE LIMITS
Silver 59-61 7440-22-4 0.01 mg/m3 OSHA (1)
Isopropyl Alcohol 20-35 67-63-0 400 ppm ACGIH
Methyl Ethyl Ketone 10-15 78-93-3 200 ppm ACGOH
Ethyl Acetate 2-10 141-78-6 400 ppm ACGIH
(1) TLV very unlikely to be reached since material is in paste form;
hence no airborne particles. Provide adequate ventilation in
firing room to remove any evolved fumes.

* Per 29 CFR 1910 the mixture has NOT been tested as a whole. All
hazardous components which comprise >= 1% of the mixture (0.1% if
carcinogenic) are listed. Percentages of individual components
are not listed as this information is considered a trade secret;
it is not required that it be disclosed.

FIRE AND EXPLOSION DATA
_________________________________________________________________
FLASH POINT (Most flammable solvent): 24oF
AUTOIGNITION TEMPERATURE (Most flammable solvent): Unknown
FLAMMABLE LIMITS IN AIR LOWER: 1.8
(Most flammable solvent): UPPER 11.4
EXTINGUISHING MEDIA: Water fog, alcohol foam, dry chemical.
SPECIAL FIRE FIGHTING PROCEDURES:
Cool exposed containers with water. When fighting use NIOSH
approved self-contained breathing apparatus with full facepiece
operated in positive pressure mode, as evolved fumes are toxic
and cause respiratory irritation.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Store below flash point, away
from open flame or sparks.

ROUTE OF EXPOSURE: ACUTE & CHRONIC SYMPTOMS: MED CONDITIONS AGGRAV.
INHALATION IRRITANT UNKNOWN
EMERGENCY FIRST AID
(for INHALATION): Remove to fresh air. If breathing is difficult,
give oxygen. If breathing stopped, start
artificial respiration.
SKIN CONTACT IRRITANT UNKNOWN
EMERGENCY FIRST AID
(for SKIN CONTACT): Remove contaminated clothing and launder before
reuse. Wash thoroughly with soap and water.
EYE CONTACT MODERATE UNKNOWN
EMERGENCY FIRST AID
(for EYE CONTACT): Flush with running water for 15 minutes, lifting
upper and lower lids.
INGESTION IRRITATION OF THE GI SYSTEM UNKNOWN
EMERGENCY FIRST AID
(for INGESTION): Drink large quantity of water.
Synergistic or additive effects of the above chemicals are unknown, as
are the effects of exposure to these chemicals in addition to others
present in the workplace.
In all cases, keep individuals warm and quiet and seek medical attention.

PERSONAL PROTECTION AND CONTROLS
_________________________________________________________________
PERSONAL PROTECTION: Avoid prolonged skin contact.
RESPIRATORY:
3
Not required, if local exhaust is satisfactory. If overexposure
occurs, use NIOSH-OSHA approved air supply respirator suitable
for organic vapors. Administrative or engineering controls
should be implemented to reduce exposure.
EYE: Chemical splash goggles or OSHA approved glasses.
SKIN: Solvent resistant gloves.
ENGINEERING CONTROLS:
Recommended ventilation, provide sufficient mechanical (general or
local exhaust) ventilation to maintain concentrations below TLV.
HYGIENIC PRACTICES:
Prevent eye contact with glasses or goggles, minimize skin
contact, use with adequate ventilation to minimize inhalation of
vapor. Do not smoke or eat in work areas. Wash hands
thoroughly prior to smoking or eating.
