Section 3 ?Hazard Identification
Emergency Overview
Avoid contact with extreme heat sources and open flame ?may emit carbon monoxide and other toxic decomposition products when burned.
Although treated to be fire resistant, service temperature should not exceed 90癈 continuously. WeathershieldTM Insulation presents no unusual
hazard if involved in a fire.
Potential Health Effects
Inhalation is the most significant route of exposure in occupational and other settings. Mild irritation of the respiratory tract is possible. The
National Toxicology Program has classified CFI products like WeathershieldTM a "nuisance dust" (PNOC, Particulate Not Otherwise Classified) ?br>
respiratory protection is recommended during installation or other handling of the product. Chemically sensitive individuals should avoid dust
exposure during installation periods.
WeathershieldTM Insulation is non-irritating to eyes and intact skin under normal industrial conditions. Even though WeathershieldTM exhibits
relatively low acute toxicity, WeathershieldTM is not intended for consumption. Ingestion of a small amount is not likely to cause harm ?larger
quantities can cause gastrointestinal symptoms such as nausea, vomiting and diarrhea.
WeathershieldTM Insulation (fibres and additives) is not considered a carcinogen by any authority.
Animal studies suggest that high-level exposure to borates can produce reproductive effects in male animals. Similar studies showed
developmental effects in fetuses of pregnant animals. Human studies of occupational exposure to borates showed no adverse effect to
reproduction. No target organ has been identified in humans.
Section 4 ?First Aid Measures
Inhalation: If irritation or difficulty in breathing occurs, remove person to fresh air. If irritation persists, seek medical attention.
Skin Contact: WeathershieldTM is non-irritating to intact skin. If broken skin is exposed, wash with soap and plenty of water. If irritation
persists, seek medical attention.
Eye Contact: For severe dust exposure, flush eyes with warm water for a minimum of 15 minutes. If irritation persists, seek medical
attention.
Ingestion: Although ingestion of significant amounts is unlikely, symptoms can include diarrhea, nausea and vomiting. Give two
glasses of water and seek medical attention.
Note to Physicians: Severe exposure to dust may produce symptoms in sensitive persons or those with pre-existing respiratory conditions.
Section 5 ?Fire-Fighting Measures
Although WeathershieldTM Insulation is treated to be fire resistant, thermal decomposition can occur when in prolonged contact with extreme
temperatures and open flame.
Suitable Extinguishing Media: Any available media (Type A fire condition)
Unsuitable Extinguishing Media: None
Special Hazards in Fire: None (fire resistant)
Required special PPE for Fire Fighters: Standard protective equipment

Section 6 ?Accidental Release Measures
Personal Precautions: Nuisance dust. Avoid prolonged exposure to small children, pets and plants.
Environmental Precautions: WeathershieldTM contains water-soluble inorganic salts that can cause damage to vegetation via root absorption
when exposed in sufficient quantity. Avoid contamination of bodies of water during cleanup and disposal ?br>
additives can be hazardous to aquatic life (see Section 12).
Methods for Cleaning: Sweep, shovel and/or vacuum up WeathershieldTM and place in containers for disposal in accordance with
applicable regulations.
Section 7 ?Handling & Storage
Handling: No special handling is required. Handling on a "first in, first out" basis is recommended to maintain package integrity.
Storage: Dry, indoor storage is recommended (ambient temperature and pressure).
Section 8 ?Exposure Controls / Personal Protection
Engineering Measures: No specific controls needed. Use good housekeeping practices to minimize potential dust generation
and accumulation.
Control Parameters: Nuisance dust.
Personal Protective Equipment: Use NIOSH-approved N95 particle mask (e.g. 3M 8210) when dust levels exceed exposure limits.
Eye Protection: Generally not required ?goggles may be warranted if environment is excessively dusty.
Hand Protection: Generally not required ?gloves are recommended if skin is broken or sensitive.
Hygiene Measures: Standard hygienic practices are recommended.
Section 9 ?Physical and Chemical Properties
Physical State: Solid Vapour Pressure: N/A
Appearance and Odour: Grey fibrous mass, low odour Vapour Density: N/A
Odour Threshold: N/A Evaporation Rate: N/A
Specific Gravity: <1 pH: 7.5 ?8.5
Boiling Point: N/A Coefficient of water / oil
Melting/Freezing Point: N/A Distribution: Not established

Section 10 ?Stability and Reactivity
Stability of Product: WeathershieldTM Insulation is a stable product.
Conditions / Materials to Avoid: Strong reducing agents and strong oxidizing agents.
Hazardous Decomposition Products: None.
Hazardous Polymerization: Will not occur.
Section 11 ?Toxicology Information
Acute toxicity: WeathershieldTM is considered to exhibit relatively low acute toxicity.
Local effects: WeathershieldTM is non-irritating to eyes and intact skin under normal industrial conditions. Although
WeathershieldTM is not intended for consumption, ingestion of a small amount is not likely to cause harm ?larger
quantities can cause gastrointestinal symptoms such as nausea, vomiting and diarrhea.
WeathershieldTM Insulation (fibres and additives) is not considered a carcinogen by any authority. Possible mutagenic activity seen in
microorganisms (E. Coli) at extreme levels of 17000 ppm/24H of boric acid exposure.
Animal studies suggest that high-level exposure to borates can produce reproductive effects in male animals. Similar studies showed
developmental effects in fetuses of pregnant animals. All animal doses administered were many times in excess of those to which
humans would normally be exposed.
Human studies of occupational exposure to borates showed no adverse effect to reproduction. No target organ has been identified in
humans.
Excessive exposure may affect human health as follows:
Skin contact: Non-irritant LDLo (boric acid, human): 1200 mg/kg.
Eye contact: possible irritant positive Draize test in rabbits, no irritation reported for humans
Ingestion: (unlikely) LDLo (boric acid, human): 429 mg/kg.
Inhalation: possible irritant LCLo (boric acid, rat): 28 mg/m?4H
Human studies show no increase in pulmonary disease in occupational populations with
chronic exposures to borate dust.

Section 12 ?Ecological Information
Ecotoxicity: Although an essential micronutrient for many plants, boron (borates) can be harmful in higher quantities. Plants
and trees can receive toxic levels via root absorption of soluble borates leached into nearby soil or waters. Care
should be taken to minimize the amount of borate chemicals released into the environment.
Fish Toxicity (Coho salmon): 40 mg B / litre (LC50 ?6H, sodium metaborate)
(Rainbow trout): 150 mg B / litre (LC50 ?4D, boric acid)
(Carassius goldfish): 178 mg B / litre (LC50 ?2H, boric acid)
Invertebrates (Daphnids): 133 mg B / litre (LC50 ?8H, boric acid)
Environmental Fate: Boron compounds are naturally occurring and ubiquitous in the environment. Boric acid decomposes in
alkaline soil to form natural borates. The borates in WeathershieldTM are soluble in water and can be
leached through normal soil.
Section 13 ?Disposal Considerations
WeathershieldTM may be disposed of as a non-hazardous waste in accordance with applicable regulations.
Section 14 ?Transport Information
WeathershieldTM is not classified as a hazardous material for transport.
