Chemical Name: Polyacrylamide
CAS Number: 9003-05-8
Concentration: 90–100%
Impurities: Residual acrylamide monomer < 0.1%
Other Components: Water as moisture content varies by product, trace formaldehyde as a preservative for liquid forms
Inhalation: Move to fresh air if dust inhaled; seek medical attention if symptoms persist
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing
Eye Contact: Rinse with plenty of water for several minutes; seek medical advice if irritation continues
Ingestion: Rinse mouth thoroughly; call physician if large amount swallowed or if discomfort occurs
Most Important Effects: Mild irritation of eyes, skin, or respiratory tract from dust exposure
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or CO2 to extinguish fire
Specific Hazards: Combustion generates carbon dioxide, carbon monoxide, and nitrogen oxides
Protective Equipment: Firefighters should use self-contained breathing apparatus
Special Precautions: Prevent runoff from entering drains or surface waters
Personal Precautions: Wear appropriate PPE to avoid dust inhalation or skin/eye contact
Environmental Precautions: Keep material out of waterways; notify authorities if large amounts contaminate water
Spill Cleanup Methods: Sweep or shovel solid material, avoid dry sweeping to minimize dust; dispose with guidance from local regulations; wash spill area thoroughly to prevent slips
Precautions for Safe Handling: Handle in a well-ventilated area; minimize dust generation; avoid contact with eyes and skin
Storage Conditions: Keep containers tightly closed in dry, cool, and well-ventilated spaces
Incompatible Materials: Strong oxidizers, reducing agents
Other Recommendations: Store away from sources of heat and ignition; segregate from food and feed
Control Parameters: Not established for Polyacrylamide, though dust limits apply (ACGIH TLV for nuisance dust 10 mg/m3)
Engineering Controls: Local exhaust ventilation recommended in case of dust generation
Personal Protective Equipment: Use safety glasses or goggles for eye protection, gloves for skin protection, and a dust mask if airborne levels are elevated
Hygiene Measures: Wash hands after handling; avoid eating or drinking near work area; remove contaminated clothing
Form: White/off-white powder or granules; sometimes a viscous liquid for certain applications
Odor: Slight characteristic odor
pH: Neutral to slightly alkaline in water (pH 5.0–8.0 for 1% solution)
Boiling Point: Not applicable (polymer)
Melting Point: Decomposes before melting
Solubility: Soluble in water; insoluble in most organic solvents
Flash Point: Not applicable for powder, typically not classified as flammable
Vapor Pressure: Negligible
Relative Density: 0.8–1.2 (solid)
Viscosity: Highly variable for liquid grades
Chemical Stability: Stable under standard conditions; avoid prolonged exposure to light and heat
Possible Reactions: Avoid strong oxidizers; does not undergo hazardous polymerization
Conditions to Avoid: Moisture for powders, extreme temperatures
Hazardous Decomposition Products: Carbon dioxide, carbon monoxide, nitrogen oxides
Acute Toxicity: Low, oral and dermal toxicity considered minimal; inhaling dust may cause irritation
Chronic Effects: Prolonged exposure to dust may lead to lung irritation
Skin/Eye Irritation: May cause mild irritation
Carcinogenicity: Not classified as carcinogen by IARC, NTP, or OSHA; residual acrylamide monomer has higher toxicity and is strictly limited in content
Other Health Effects: No evidence of reproductive toxicity in animal studies at typical exposure levels
Aquatic Toxicity: Low toxicity to aquatic organisms at typical concentrations used for water treatment; polyacrylamide itself is not classified as hazardous
Mobility: High solubility in water permits wide dispersion in aquatic environments; settles as solid when undissolved
Persistence and Degradability: Biodegradable slowly under typical conditions; large molecular size hinders rapid breakdown
Bioaccumulation: Not expected to bioaccumulate in living organisms
Other Concerns: Product can alter water’s physical properties, including increased turbidity if spilled in large quantities
Waste Disposal: Follow local, state, and federal regulations; sweep up and place in properly labeled containers
Contaminated Packaging: Triple rinse, then dispose as unused product
Precautions: Prevent entry to sewers or watercourses; do not landfill with food or feed
Recycling Information: Some forms may be suitable for recycling or energy recovery processes, consult with experienced waste handlers
UN Number: None assigned for Polyacrylamide
Proper Shipping Name: Not regulated as hazardous for transport
Transport Hazard Class: Non-hazardous
Packing Group: No regulation
Sea (IMDG) & Air (IATA): Not regulated; standard precautions for solids or liquids apply
Special Precautions for Transport: Protect from moisture; avoid rough handling of containers
OSHA Status: Not hazardous; dust limits may apply in workplace settings
EPA: Registered for use in selected applications such as drinking water and wastewater treatment
TSCA: Listed in the US Toxic Substances Control Act inventory
Other Global Inventories: Included on EU REACH, Canadian DSL, Japanese ENCS, Australian AICS
Warning Statements: Residual acrylamide considered hazardous; manufacturers control level strictly
Labeling Requirements: Provided by supplier; include risk and safety phrases per GHS or national guidelines
