See OSHA 29 CFR 1910.1200
Potential health effects (acute and chronic):
Routes of entry:
Eye: Direct contact irritates slightly with redness
and swelling.
Health Hazards
(acute and chronic): The degree of injury depends on the duration
of exposure.
Inhalation: Vapors may injure lungs, blood, liver, kidneys,
and nervous system.
Skin: A single relatively short exposure irritates.
Repeated prolonged contact irritates seriously.
Over exposure may irritate internally.
Ingestion: Small amounts transferred to the mouth by fingers
should not cause injury. Swallowing large amounts will
injure seriously.
Signs and symptoms of exposure:
Prolonged over exposure may injure lungs, kidneys,
liver, blood, and nervous system and aggravate
existing eye, skin and respiratory disorders.
Medical condition aggravated by exposure:
Short vapor exposure may cause drowsiness and
irritate throat.
Routes of entry: Inhalation, ingestion or skin contact.
Carcinogenicity:
Not determined
Emergency and first aid procedures: Skin: Wipe off and flush with water. Eyes: Immediately flush thoroughly with water for at least 15 minutes. Inhalation: Remove to fresh air. Artificial respiration if breathing has stopped. Get medical attention immediately if symptoms persist. Ingestion: Get medical attention immediately. Do not induce vomiting. Prevent aspiration of liquid into lungs. Never give anything by mouth to an unconscious person.
Take proper precautions to ensure your own health and safety before attempting to rescue and providing first aid. These practices include avoiding all unnecessary exposure and removal of the material from eye, skin and clothing. Inhalation: If symptoms are experienced, move victim to fresh air, if symptoms persist, obtain medical attention. Inhalation of the mist from the aerosol form could potentially be very dangerous and even life-threatening. After all, this is a vacuum leak sealant and one can only imagine what a vacuum sealant could do to the capacity of the lungs to exchange oxygen. Medical assistance should be obtained at once. Eye contact: Wash eyes with clean low pressure water. Seek medical assistance without delay. Skin contact: If the polymer should contact the skin from either the aerosol or non- aerosol form, wash with plenty amounts of water. Ingestion: This route of exposure is not anticipated. However, cured silicone resins are not perceived to be highly toxic in the body. Nevertheless, medical advice should be obtain at once. Fire Extinguishing Media: Dry Chemical, water fog, foam, carbon dioxide, other Special Firefighting Procedure: Wear self-contained breathing apparatus due to thermal decomposition of products and protective clothing should be worn. Unusual Fire and explosion hazards: Vapors are heavier than air and can travel along the ground to remote areas. Try to remove any aerosol cans from the path of the first because aerosol cans, when over heated, will explode. Fire And Explosion Hazard Data Flash Point............... None (Trichloroethylene) Flammable Limits in Air... Flammable limit in air, % by vol. (trichloroethylene) LEL (Lower Explosive Limit) : 10.5% UEL (Upper Explosive Limit) : 8.9%
Spill Response: Use absorbent material to collect and contain for salvage or disposal. Remove all sources of ignition and wear protective equipment. Use chemical worker goggles. use respiratory protection unless local exhaust ventilation is adequate or air sample data exposures are within TLV and PEL guidelines. Rubber or plastic gloves are recommended. Remove contaminated clothing and shoes as soon as practical and clean before reuse.
Precautions to be taken in handling and storing:
Keep container closed and away from heat. In the case of the
aerosol form of the product, this is even more important because
shelf life of the product will be greatly entended if not exposed
to warmer temperatures.
Other precautions:
When processing at elevated temperatures, provide ventilation to
control exposures within OSHA and ACGIL limits. Aerosol or spray
applications may require added precautions. Evolution rate is
highest during the first few hours, then subsequently approaches
zero.
Do not store neat heat of flame or other source of ignition
(e.g. Electrical wiring or motors).
Other: Keep container tightly closed. Store in cool
dry well ventilated area.
Handling and Storage:
Do not store neat heat of flame or other source of ignition
(e.g. Electrical wiring or motors).
Use protective rubber or plastic gloves when handling to
avoid skin contact. Always use proper eye protection.
Keep protective clothing in good clean condition and clean
thoroughly after each use.
Engineering Controls:
Use only in well ventillated area in order to prevent the build up of
vapors or fumes.
Personal Protection:
Inhalation: Use appropriate respiratory protection when using the
product in aerosol form. Avoid breathing the vapors of the product in
either product form.
Skin: Use protective clothing such as long sleeves or a lab
coat. This is especially recommended when using the aerosol form of the
product but good practice when using any form of the product.
Eye: Always use safety glasses, preferably chemical
goggles when using any form of this product.

Carcinogenicity:
Not determined
Exotoxicity:
Exotoxicity is expected to be low based the fact that solvents
evaporate quickly and the silicone polymerizes into an inert
substance with virtually no water solubility. No other information
is known on this topic.
Environmental Fate:
No information found in our selected references.
Bioaccumulation:
Not expected to occur.
Disposal considerations: All local, state, federal or other regulations concerning health and pollution should be reviewed to determine approved disposal procedures.
Non-aerosol form of the product:
Proper Shipping Name: Silicone resin solution
DOT Hazard Class: 2.2
UN/NA ID: 1950
Packing Group: III
Labels: Aerosol, Non-Flammable N. O. S.
Marine Pollutant: Probably not because of its very low solubility in
water of the final cured resin. Other solvents
evaporate quite quickly.
