Extinguishing Media – Foam, CO₂, dry media, halon 1211.

Special Fire Fighting Procedures –Wear self-contained breathing apparatus and protective clothing. Cool fire exposed containers to prevent rupturing.

Unusual Fire and Explosion Hazards – Exposure to temperature above 120ºF may cause bursting. Cured foam is organic and therefore will burn in the presence of sufficient heat.

Signs and Symptoms of Exposure:

Eyes—May be irritating to eyes. Foam contact can cause physical damaged due to adhesive character.

Skin—May cause localized irritation, reddening or swelling. Prolonged exposure may lead to sensitization and/or dermatitis.

Inhalation—May irritate mucous membranes with tightness in chest, coughing, or allergic asthma-like sensitivity. Extensive overexposure can lead to respiratory symptoms like bronchitis and pulmonary edema. These effects are usually reversible.

Ingestion— May cause irritation of mucous membranes in the mouth and digestive tract.

Medical Conditions Generally Aggravated –None Known

Emergency and First Aid Procedures.

Eyes—Flush with large amounts of cool running water for at least 15 minutes while holding upper and lower lids open. If irritation persists get medical attention immediately.

Skin—Use a rag to remove excess foam from skin and remove contaminated clothing. Use a mild solvent, such as acetone (nail polish remover) or mineral spirits may help in removing

Inhalation—Remove to fresh air. Seek medical attention immediately. If breathing stops give artificial respiration.

Ingestion—Do not induce vomiting. Drink 1 to 3 large glasses of water. Seek medical attention immediately. Never give anything orally to an unconscious person.

Section VII – Precautions For Safe Handling and Use

Steps to be Taken in Case Material is Released or Spilled.

Maintain local exhaust and adequate ventilation. No smoking. Keep sparks, heat sources and open flame far away from spill or leak. Uncured foam is very sticky remove immediately using acetone or mineral spirits with a rag. Once foam has cured, it can be physically removed by scraping, sanding, etc. Dispose of plastic waste (foam plastic) in accordance with Federal, State and local laws.

Waste Disposal Method – Aerosol cans, when emptied and depressurized through normal use, pose no disposal hazard and should be recycled. Consult Federal, State and local authorities for approved procedure.

Precautions to be Taken in Handling and Storing –

Store in a cool, dry area away from heat or open flame. Do not store at temperatures above 120ºF. KEEP OUT OF REACH OF CHILDREN.

Section VIII – Control Measures

Respiratory Protection (Specify Type) – None needed for proper use in accordance with label directions. Wear a NIOSH/MSHA approved respirator with organic vapor cartridges if recommended exposure level is exceeded.
