2. COMPOSITION/INFORMATION ON INGREDIENTS

3. HAZARDS IDENTIFICATION

POTENTIAL HEALTH EFFECTS (See Section 11 for toxicological data.)

• EYE: Solid or dust may cause irritation or corneal injury due to mechanical action.
• SKIN: Mechanical injury only. Essentially nonirritating to skin. Skin absorption is unlikely due to physical properties.
• INGESTION: Ingestion is unlikely due to physical state. Physical injury only. May cause choking if swallowed.
• INHALATION: Dust may cause irritation to upper respiratory tract. Excessive exposure to chlorodifluoroethane and/or ethyl chloride blowing agents may cause central nervous system depression, anesthetic effects and irregular heartbeats (cardiac sensitization). In animals, excessive exposure to chlorodifluoroethane has caused low blood pressure, respiratory stimulation and chest tightness (bronchoconstriction).

  Concentrations of the ethyl chloride and chlorodifluoroethane blowing agents anticipated incidental to proper handling are expected to be well below those which cause the acute inhalation effects listed above, as well as below the OSHA PEL and Dow Industrial Hygiene Guide.

• SYSTEMIC (OTHER TARGET ORGAN) EFFECTS: Repeated exposures to dusts of this material are not anticipated to result in systemic toxicity or permanent lung injury; however, such exposures may cause less severe respiratory effects. Excessive exposure to HBCD may increase the blood and tissure levels of bromine.
• CANCER INFORMATION: Neither polystyrene foam dust nor chlorodifluoroethane caused cancer in long-term animal studies. Uterine tumors seen in female mice given high doses of ethyl chloride for their life times are believed to be unique to female mice. Such tumors did not occur in rats similarly exposed. These results are not believed to be relevant to humans.
• TERATOLOGY (BIRTH DEFECTS): No birth defects were seen in animal studies with ethyl chloride or chlorodifluoroethane.

4. FIRST AID

• EYE: Flush eyes with plenty of water; mechanical effects only.
• SKIN: Wash off in flowing water or shower.
• INGESTION: No adverse effects anticipated by this route of exposure incidental to proper industrial handling.
• INHALATION: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, oxygen should be administered by qualified personnel. Call a physician or transport to a medical facility.

NOTE TO PHYSICIAN: Exposure may increase "myocardial irritability" . Do not administer sympathomimetic drugs unless absolutely necessary. No specific antidote. Supportive care. Treatment based on judgment of the physician in response to reactions of the patient.

5. FIRE FIGHTING MEASURES

• FLAMMABLE PROPERTIES
  
  • FLASH POINT: 670F, 354C Flash Ignition Temperature. METHOD USED: ASTM D1629 Proc. B.
  • FLAMMABILITY LIMITS
    • LFL: Not applicable
    • UFL: Not applicable



• HAZARDOUS COMBUSTION PRODUCTS:
  Hazardous combustion products may include and are not limited to carbon dioxide and carbon monoxide.



• EXTINGUISHING MEDIA:
  Water spray, fog, carbon dioxide, dry chemical.



• FIRE FIGHTING INSTRUCTIONS:
  This polystyrene foam plastic product is combustible. This product contains a flame retardant additive to inhibit accidental ignition from small fire sources. However, once ignited this product will burn, emitting a dense black smoke. During shipping, storage, and use this product must be protected from flame or other high heat sources. During certain fabrication operations such as cutting and grinding, blowing agents contained in the foam and dust may be released. Accumulation of blowing agents or dust in air could present flammability and explosion concerns. Provide adequate ventilation, and appropriate dust handling systems where needed. This product should not be shipped, stored or used in virtually airtight spaces to prevent the build-up of combustible vapors.



• PROTECTIVE EQUIPMENT FOR FIRE FIGHTERS:
  Wear positive-pressure, self-contained breathing apparatus (SCBA) and protective fire fighting clothing (including fire fighting helmet, coat, pants, boots, and gloves).

6. ACCIDENTAL RELEASE MEASURES (See section 15 for Regulatory Information)

• PROTECT THE ENVIRONMENT: Fire water run off may be toxic.



• CLEANUP: Pick up, or if dust or in small pieces, sweep up, and place in suitable container for disposal.

7. HANDLING AND STORAGE

• HANDLING:
  Mechanical handling equipment can cause formation of dusts. Maintain good housekeeping. Layers of flammable dusts should not be permitted to accumulate.


• STORAGE:
  Flammable vapors may accumulate in some storage situations. Storage, use and handling areas should be "No Smoking" areas. Limited industrial hygiene measurements of ethyl chloride in ventilated warehouses and production facilities indicate that ethyl chloride present in the air is below the current 150 ppm IHG for ethyl chloride.
  
  Gas fired recirculating air furnaces or heaters, gas water heaters, etc., drawing air from areas where there may be a presence of ethyl chloride and chlorodifluoroethane gases from storage or fabrication of extruded polystyrene foam, can be subjected to rust and corrosion problems as a result of thermal decomposition of the blowing agents to hydrogen chloride.



NOTICE: This polystyrene foam plastic product contains no fire-retardant additive. It is COMBUSTIBLE and should be protected from flame and other high heat sources. For more information, contact Dow (1-800-441-4369).

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

• ENGINEERING CONTROLS: Provide general and/or local exhaust ventilation to control airborne levels below the exposure guidelines.



• PERSONAL PROTECTIVE EQUIPMENT
  
  • EYE/FACE PROTECTIONS: Use safety glasses. If there is a potential for ;exposure to particles which could cause mechanical injury to the eye, wear chemical goggles.
  
  
  • SKIN PROTECTION: No precautions other than clean body-covering clothing should be needed.
  
  
  • RESPIRATORY PROTECTION: Atmospheric levels should be maintained below the exposure guideline. When respiratory protection is required for certain operations, use an approved air-purifying respirator. In dusty atmospheres, use an approved dust respirator.
  
  
• EXPOSURE GUIDELINE (S):
  
  • Ethyl chloride: Dow IHG is 150 ppm; ACGIH TLV is 100 ppm, skin, A3, OSHA PEL is 1000 ppm.
  • Chlorodifluoroethane: AIHA WEEL is 1000 ppm, TWA.

PELs are in accord with those recommended by OSHA, as in the 1989 revision of PELs.

9. PHYSICAL AND CHEMICAL PROPERTIES

• APPEARANCE/PHYSICAL STATE: Rigid cellular foam board.
• ODOR: No odor.
• VAPOR PRESSURE: Not applicable
• VAPOR DENSITY: Not applicable
• BOILING POINT: Not applicable
• SOLUBILITY IN WATER/MISCIBILITY: None
