NFPA Rating: Not known
Emergency overview:
This material is not hazardous by OSHA Hazard Communication
Definition
Physical Health Hazards:
None known.
Physical state: Solid
Color: White to light yellow colored, free flowing powder
Odor: Slightly pungent
Odor threshold: No data available
Toxicity Data:
Oral LD50 (Rat) >5.010 mg/kg - practically nontoxic
Dermal LD50 (Rabbit) >2.000 mg/kg - nor more than slightly toxic
Irritation Data:
Eye (Rabbit): 3.3 on a scale of 110.0 - slightly irritating
Skin (Rabbit): 0.0 on a scale of 8.0 - non-irritating
Potential Health Effects:
Routes of exposure:
Inhalation, Ingestion, Skin Contact
Signs and Symptoms of Acute Exposure:
Not known. Animals subjected to long term exposure to polyvinyl
alcohol under the skin showed no increase in tumor formation where
a powdered form was used. However, an increase in tumors was reported
in similar studies where polyvinyl alcohol sponges were implanted
(IARC Monographs 19:351-359). NIOSH registry of toxic effects of
chemical substances reported polyvinyl alcohol as "animal positive"
for carcinogenicity. Although the sponge form of polyvinyl alcohol has
caused fibrosis in humans, the information is not considered relevant to
normal workplace exposure to polyvinyl alcohol resins and therefore,
these resins are not considered to pose a carcinogenic risk to a worker.
Skin contact:
May be irritating.
Inhalation:
May be harmful
Eye contact:
Mechanical irritation is possible, therefore the dust form of the
material should be kept from contacting the eyes.
Ingestion:
May be harmful.
Chronic Health Effects Summary:
No known chronic health effects.
Conditions Aggravated by Exposure:
No known conditions are aggravated by this material. However, there
is a dust-explosion potential present with the use of this material,
especially when working with larger (than laboratory) quantities.
Handle in accordance with good industrial hygiene and safety practices.
These practices include avoiding unnecessary exposure and removal of the
material from eyes, skin and clothing.
Inhalation:
If symptoms are experienced, move victim to fresh
air, if symptoms persist, obtain medical attention.
Eye Contact:
Wash eyes with clean low-pressure water. If
irritation persists, seek medical advice.
Skin Contact:
If powdered or dust form of the material contacts the skin,
immediately flush the skin with large amounts of water. If
irritation or other symptoms persist, seek medical attention.
Ingestion:
Adverse health effects due to ingestion are not
anticipated. If gastric irritation or discomfort
persists, seek medical advice.
NFPA Rating: Not known
Flammability classification: Not classified.
Flash Point/Method: Not applicable
Auto-Ignition Temperature: Not known
Flammable Limits:
Lower: Not applicable
Upper: Not applicable
Hazardous Combustion/Decomposition Products:
Carbon monoxide, carbon dioxide, formaldehyde, acetic acid,
acrolein (trace) may be formed.
Special Conditions to Avoid:
Dust particles in the atmosphere of this material may be explosive.
Keep away from heat, sparks, flame and all other ignition sources.
Keep containers or bags tightly closed. Clean up all dust
accumulations. Prevent dust accumulations and dust clouds,
possibly using water to "wet" dry dust from forming a cloud.
Extinguishing Media:
Water spray or any Class A extinguishing agent.
Fire Fighting Instructions:
Protective Equipment/Clothing: Wear a NIOSH approved positive
pressure self-contained breathing apparatus and firefighter
turnout gear. There could be the evolution of toxic products of
combustion. Firefighting equipment should be fully decontaminated
after use.
Instructions:
Use flooding quantities of water until well after fire is out.
Unusual fire and explosion hazards:
Dust when mixed in sufficient quantities with air creates a
potential for explosive concentrations.
Release response:
Vacuum or otherwise pick up and retain for recycle or disposal.
Do not flush spilled material to the sewer or the environment.
Avoid creating a dust cloud since this could create an a potential
for a dust explosion hazard. Use vacuum equipment designed especially
for handling combustible dust.
Reportable Quantities:
See Section 15: Regulatory information.
Handling: Handle in accordance with good industrial hygiene and safety practices. These practices include avoiding unnecessary exposure and removal of the material from eyes, skin and clothing. Storage: Keep container dry. Store away from excessive heat, sparks and flame. Avoid creating any dust cloud when handling. Keep container close to prevent contamination.
Engineering Controls: Provide sufficient ventilation to minimize exposure. Use local mechanical exhaust ventilation at sources of air contamination such as open process equipment. Personal Protection: Inhalation: Avoid breathing dust. Use NIOSH/OSHA approved equipment when airborne exposure is excessive. High airborne concentrations may require use of self-contained breathing apparatus or supplied air respirator. Respiratory protection programs must be in compliance with 29 CFR 1910.134. Skin: Skin contamination should be minimized as good industrial practice. Wearing of protective gloves is recommended. Wash hands and contaminated skin after handling. Eye: Always use safety glasses, even for work with small quantities, such as the making Formvar filmed grids.
Boiling Point/Range: Not applicable
pH: Not applicable
Vapor Pressure: Not applicable
Viscosity: Not applicable
Specific Gravity (Water = 1): 1.1-1.3

The product is stable.
Conditions to Avoid:
Avoid contact with excessive heat, sparks or open flame
or dust accumulation.
Incompatibility with:
None known
Hazardous Products of Deposition:
Carbon dioxide, carbon monoxide, formaldehyde,
acetic acid, acrolein (trace).
Reactions with Air and Water:
Does not react with air, water or other common
materials.
Summary:
Not considered to be toxic to humans or animals
Component:
Polyvinyl formal resin 99.9+%
Formaldehyde < 0.1%
Skin Effects:
No skin effects are expected from contact.
Acute Oral Effects:
Animal studies showed no adverse health
effects when performed on polyvinyl alcohol.
Acute Inhalation Effects:
None known
Subchronic Effects:
None known
Chronic Effects/Carcinogenicity:
None expected from polyvinyl formal resin, however, formaldehyde is a
suspected human carcinogen by IARC. Note: Formaldehyde is present but in
less than 0.1% levels.
Reproductive/Development Effects:
No reproductive or developmental effects are expected.
Exotoxicity: Exotoxicity is expected to be low based on the low
water solubility of polymers. No other information
is known on this topic.
Environmental Fate: No information found in our selected references.
Bioaccumulation: Not expected to occur.
Polyvinyl formvar is not a "hazardous waste" as that term is defined in the Resource Conservation and Recovery Act (RCRA), 40 CFR 261, "Identification and Listing of Hazardous Waste". Burn in an approved incinerator or dispose of in an approved landfill in accordance with all applicable local, state, and federal laws and regulations. Consult your appropriate regulatory officials for information on such disposal.
