3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
PHYSICAL APPEARANCE: Amber liquid.
IMMEDIATE CONCERNS: Irritating to eyes, respiratory system, and skin. Inhalation at levels
above the occupational exposure limit could cause respiratory sensitization.
POTENTIAL HEALTH EFFECTS
EYES: Liquids, vapors, or mists are irritating to the eyes and can cause stinging, burning,
lachrymation, or tearing.
SKIN: Moderate irritant. Repeated and/or prolonged contact may cause skin sensitization.
INGESTION: Ingestion may cause irritation of the gastrointestinal tract and gastrointestinal
discomfort with any or all of the following symptoms: nausea, vomiting, lethargy, or diarrhea.
INHALATION: Inhalation of vapors or mist at concentrations above the TLV can cause
respiratory tract irritation. (nose, throat, lungs) Chronic inhalation can result in sensitization.
SIGNS AND SYMPTOMS OF OVEREXPOSURE
Spal-Pro RSF 鈥淏鈥? Page 2 of 8
EYES: Contact may cause moderate irritation consisting of transient redness, swelling, and
mucous membrane discharge to the conjunctiva. Prolonged contact with the eyes may cause
reversible corneal opacity to occur, with no visual impairment expected.
SKIN: Contact may cause minor irritation consisting of transient redness and/or swelling.
Individuals with skin sensitization can develop these symptoms from contact with a small amount
of liquid or vapors.
INGESTION: Ingestion may cause irritation of the gastrointestinal tract and gastrointestinal
discomfort with any or all of the following symptoms: nausea, vomiting, lethargy, or diarrhea.
INHALATION: Vapors or mist, especially as generated from heating the material or as from
exposure in poorly ventilated areas or confined spaces, are irritating and cause nasal discharge,
coughing, discomfort in nose and throat, and breathing obstruction. Individuals with respiratory
sensitization may experience allergic respiratory reactions when exposed to amounts below the
exposure guidelines.
MEDICAL CONDITIONS AGGRAVATED: Asthma, other respiratory disorders (bronchitis,
emphysema, bronchia hyperreactivity), skin allergies, eczema.
ROUTES OF ENTRY: Inhalation, skin contact, eye contact, ingestion.
SENSITIZATION: Any individual with isocyanate sensitization should not be exposed to this
product. These individuals can react to exposure well below the TLV. Symptoms can occur
immediately or several hours after exposure.
4. FIRST AID MEASURES
EYES: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower
eyelids occasionally. Get immediate medical attention.
SKIN: Remove contaminated clothing. Wash affected areas thoroughly with soap and water. Wash
clothing thoroughly before reuse. For severe exposure, seek medical attention immediately. For
lesser exposure, seek medical attention if swelling or redness occurs, or if irritation persists after
being washed.
INGESTION: Do not induce vomiting. Never give anything by mouth to a drowsy or unconscious
person. If the individual is conscious, rinse mouth with water. Give 1 to 2 cups of water to drink.
Seek immediate medical attention.
INHALATION: Remove individual from exposure, keep warm and at rest. If dizzy or shows signs of
respiratory distress, obtain immediate medical attention. Asthmatic-type symptoms may develop
and may be immediate or delayed up to several hours.
NOTES TO PHYSICIAN: Symptomatic and supportive therapy as needed. Following severe
exposure, medical follow-up should be monitored for at least 48 hours. May cause respiratory
sensitization or asthma-like symptoms. Respiratory symptoms, including pulmonary edema, may
be delayed.
5. FIRE FIGHTING MEASURES
Spal-Pro RSF 鈥淏鈥? Page 3 of 8
FLASHPOINT AND METHOD: > 200 oF (Closed Cup)
EXTINGUISHING MEDIA: Dry Chemical, Carbon Dioxide, Chemical Foam, Water Fog or Spray.
HAZARDOUS COMBUSTION PRODUCTS: Carbon Monoxide, Carbon Dioxide, Nitrous Oxide,
and HCN.
COMMENT: Product reacts slowly with water to produce carbon dioxide which may rupture
closed containers. This reaction accelerates at higher temperatures.
FIRE FIGHTING PROCEDURES: Isolate fuel supply from fire. Use water spray to cool fire-
exposed surfaces and containers. Fire fighters should wear self-contained breathing apparatus in
addition to emergency fire fighting protective clothing.
6. ACCIDENTAL RELEASE MEASURES
SMALL SPILL: Clean up spills wearing proper personal protective equipment. (See section 8)
Absorb with dry chemical absorbent, earth, sand, or any other inert material. Place in a chemical
waste container. Move to outside well-ventilated area. Treat with 10 parts decontamination
solution to 1 part isocyanate. Mix well. Allow to stand uncovered 48 hours before disposal.
LARGE SPILL: Eliminate all ignition sources. Evacuate and ventilate the area. Create a dike or
trench to contain materials. Prevent entry into waterways, sewers, basements or confined areas.
Clean-up personnel should wear appropriate personal protection equipment. (see section 8) Absorb
with dry chemical absorbent, earth, sand, or any other inert material. Do not use combustible
material such as sawdust. Place in a chemical waste container. Move to outside well-ventilated
area. Treat with 10 parts decontamination solution to 1 part isocyanate. Mix well. Allow to stand
uncovered 48 hours before disposal. Clean spill area with decontamination solution and allow to
stand for 15 minutes before removal. Test atmosphere for MDI.
DECONTAMINATION SOLUTION: Decontamination solution: concentrated ammonia (5%),
detergent (2%), and water (93%)
RELEASE NOTES: Spills and releases may have to be reported to Federal and/or local authorities.
See Section 15 regarding reporting requirements.
SPECIAL PROTECTIVE EQUIPMENT: See Section 8. Clean-up crews should always wear
Personal Protective Equipment.
COMMENT: Dispose of by any standard method of disposal in accordance with good industrial
practice and in compliance with federal, state, and local environmental protection regulations.
7. HANDLING AND STORAGE
HANDLING: Wear proper personal protective equipment. Use in a well ventilated area. Avoid
smoking, bare lights, or ignition sources. Avoid physical damage to containers.
STORAGE: Protect from atmospheric moisture. Keep containers sealed in order to avoid
Spal-Pro RSF 鈥淏鈥? Page 4 of 8
contamination. Do not reseal if contaminated. After container has been opened, blanket with
nitrogen before resealing. Store indoors in a cool, well-ventilated area.
STORAGE TEMPERATURE: 60 oF 鈥? 120 oF
SHELF LIFE: 6 Months
SPECIAL SENSITIVITY: Material is hygroscopic and reacts with water. It will form cured particles
or a film when exposed to atmospheric moisture. Blanket containers with nitrogen before
resealing.
COMMENT: Reacts slowly with water to produce carbon dioxide which may rupture closed
containers. This reaction accelerates at higher temperatures. See Section 10 for more information
on precautions concerning storage and handling of this material.
