3. Hazard Identification
Appearance and Odor: iLevel鈩? Subfloor Adhesive is a green, viscous liquid; slight odor.
Primary Health Hazards: The primary health hazards posed by this product are slight skin irritation due
to prolonged, repeated contact and eye irritation upon direct contact.
CAUTION: Although it is not conducted under normal circumstances, power sanding the finished product
following application of the adhesive may create airborne dust which can contain silica. Avoid
sanding the finished product without an assessment of potential exposure levels and corresponding
use of personal protective equipment (see section 8 below).

3. Hazard Identification, (cont鈥檇.)
Primary Route(s) of Exposure:
Ingestion: Not considered to be a likely route of exposure.
Skin: Prolonged, repeated contact with the product may result in slight skin irritation. Avoid
contact with skin as much as possible.
Inhalation: The product is low in volatility and is not expected to pose an inhalation hazard under
normal conditions. The silica is bound in the product matrix and will not be released as a dust
under normal conditions of use. Power sanding of the applied product may release silica dust; see
further information on this MSDS.
Eye: Direct contact with the product may cause minor eye irritation.
Medical Conditions Generally Aggravated by Exposure: Existing skin conditions may be exacerbated
by prolonged, repeated contact with the product.
Signs and Symptoms of Exposure:
Acute Health Hazards: Irritating to the skin and eyes on contact.
Chronic Health Hazards: None are expected due to the low percentage by weight of the hazardous
ingredients in this product and if airborne dusts are not created from the finished product. Power
sanding may create airborne dust which can contain crystalline silica. Excessive exposure to silica,
crystalline (quartz) can cause silicosis, a fibrosis or scarring of the lung tissue, characterized by
cough and shortness of breath. Silicosis may occur over many years of low-level exposure and may
be progressive, leading to disability and possibly death. Silica, crystalline (quartz) of respirable
particle size is listed by some organizations as a known human carcinogen.
Carcinogenicity Listing:
NTP: Silica, Crystalline (quartz) is known to be a Human Carcinogen
IARC Monographs: Silica, Crystalline (quartz) Group 1, Carcinogenic to Humans
Titanium dioxide - Group 2B, Possibly carcinogenic to humans.
OSHA Regulated: Not Listed
4. Emergency and First-Aid Procedures
Ingestion: Not a typical route of occupational exposure. Small amounts are not expected to produce
adverse health effects. If larger amounts are ingested, seek medical attention immediately.
Eye Contact: Flush eyes with clean water for at least 15 minutes. Seek medical help if irritation persists.
Skin Contact: Wash exposed skin with mild soap and water. A mild moisturizing cream may assist with
reducing symptoms of skin irritation. Seek medical attention if rash, irritation or dermatitis persists.
Skin Absorption: Not known to occur under normal use.
Inhalation: Remove worker to fresh air. Seek medical attention if persistent irritation, severe coughing
or breathing difficulty occurs. Provide medical personnel a copy of this Material Safety Data Sheet.
Note to Physician: None

6. Accidental Release Measures
Steps to be Taken In Case Material Is Released or Spilled: Confine spill to a small area. Use
absorbent material to clean up. Place in container for disposal according to local environmental
regulations.
7. Handling and Storage
Precautions to be Taken In Handling and Storage: Do not store above 125掳 F (51.7掳 C) or below
freezing or damage to product may occur.
Other Precautions: For professional or industrial use only. Always read and follow label instructions.
Keep out of reach of children. Not for consumption. Do not smoke while using/applying this product.
Avoid skin and eye contact. To prevent build-up and inhalation of vapors from this product, ensure
proper ventilation by opening windows and doors to achieve adequate natural ventilation or provide
mechanical dilution ventilation if necessary. Turn off all pilot lights, flames, stoves, heaters, electric
motors, welding equipment and other sources of ignition. Never use a welding or cutting torch on or
near product containers. Close product containers when not in use. Empty product containers must
not be washed or re-used for any purpose. Containers may be hazardous when empty. Wash hands
thoroughly after handling. For spray applications, use only with approved spray equipment.
CAUTION: Avoid sanding the finished product following application of the adhesive - power sanding may
create airborne dust which can contain crystalline silica.
8. Exposure Control Measures, Personal Protection
Personal Protective Equipment:
RESPIRATORY PROTECTION 鈥? If the product is power sanded where the exposure limit may be
exceeded and engineering controls are not feasible, a half-face high efficiency particulate respirator
(e.g. NIOSH type N100 filter) may be worn for up to ten times the exposure limit or the maximum use
concentration specified by the appropriate regulatory agency or respirator supplier, whichever is
lowest. Any other respirator requirements should be evaluated and implemented as part of a
respiratory protection program (e.g. OSHA 1910.134 in the USA).
EYE PROTECTION 鈥? Safety glasses. Use a face shield if spraying product.
PROTECTIVE GLOVES 鈥? Impervious chemical gloves are recommended to avoid repeated or prolonged
skin contact.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT 鈥? General protective clothing to suit work
conditions.
WORK/HYGIENE PRACTICES 鈥? Follow good hygiene and housekeeping practices.
Ventilation:
LOCAL EXHAUST 鈥? Not likely to be needed. Natural ventilation should be adequate under normal
conditions.
MECHANICAL (GENERAL) 鈥? Not likely to be needed. To prevent build-up of vapors from this product,
ensure proper ventilation by opening windows and doors to achieve adequate natural ventilation or
provide mechanical dilution ventilation if necessary.
SPECIAL 鈥? Self-contained breathing apparatus (SCBA) recommended when fighting a fire.

biodegradation in aerobic and anaerobic environments (100% removal of EG within 24 h to 28 days).
In air ethylene glycol reacts with photo-chemically produced hydroxyl radicals with a resulting
atmospheric half-life of 2 days. Diethylene glycol is not expected to partition to soil or sediment and
can be expected to biodegrade quickly in soil or water. Ammonia is fully soluble in water and readily
metabolized by bacteria. Ammonia would not be expected to pose any localized environmental
hazard at the very amounts contained in the product.
