3. HAZARDS IDENTIFICATION

 

EMERGENCY OVERVIEW:                 Solid pellets with slight or no odor.

Spilled pellets create slipping hazard. Can burn in a fire creating dense toxic smoke. Molten plastic can cause severe thermal burns. Fumes produced during melt processing may cause eye, skin and respiratory tract irritation. Secondary operations, such as grinding, sanding or sawing, can produce dust which may present an explosion or respiratory hazard.

 

POTENTIAL HEALTH EFFECTS

EYE:                               Product may cause irritation or injury due to mechanical action.

SKIN:                             Pellets not likely to cause skin irritation.

INGESTION:                 Not acutely toxic.

INHALATION:             Pellet inhalation unlikely due to physical form.

 

CHRONIC/CARCINOGENICITY

NTP:                              Not Tested

OSHA:                           Not Regulated

IARC:                             Not Listed

 

MELT PROCESSING HEALTH EFFECTS:    Molten plastic can cause severe burns.

 

Processing fumes may cause irritation to the eyes, skin and respiratory tract, and in cases of severe over-exposure, nausea and headache.

 

Prolonged or repeated exposure to triarylphosphate fire retardants may cause a reduced level of monocyte "color staining" with esterase dependent dyes based upon human exposure. There have been no diseases or adverse health effects associated with this reduced cell staining observation.

 

Grease-like processing fume condensates on ventilation duct work, molds and other surfaces can cause irritation and injury to skin.

 

MEDICAL RESTRICTIONS:            There are no known human health effects aggravated by exposure to this product. However, certain sensitive individuals and individuals with respiratory impairments may be affected by exposure to components in the processing fumes.

 

NOTE:                                                    OSHA, IARC and/or NTP have listed carbon black and heavy metals, present in some colorants, as carcinogens. If these colorants are present in this product, they are shown in SECTION 2. These colorants are essentially bound to the plastic matrix and are unlikely to contribute to workplace exposure under recommended processing conditions.

 

4. FIRST AID MEASURES

 

EYES:                              Remove contact lenses at once. Immediately flush  eyes well with copious quantities of water or normal saline for at least  20-30 minutes. If irritation persists, seek medical attention.

 

SKIN:                              Wash skin thoroughly with soap and water. Seek medical attention if rash or burn occurs.

 

INGESTION:                 Not probable. If a large amount is swallowed, seek medical attention.

 

INHALATION:              Not likely to be inhaled due to physical form.

 

MELT PROCESSING:  For molten plastic skin contact, cool rapidly with water and immediately seek medical attention. Do not attempt removal of plastic without medical assistance. Do not use solvent for removal.

 

For processing fume inhalation irritation, leave contaminated area and breathe fresh air. If coughing, difficult breathing or any other symptoms develop seek medical attention at once, even if symptoms develop at a later time.

 

For skin contact with fume condensate, immediately wash thoroughly with soap and water. If irritation develops seek medical attention.

 

5. FIRE FIGHTING MEASURES

 

FIRE FIGHTING:                   Approved pressure demand breathing apparatus and protective clothing should be used for all fires. Water spray is the preferred extinguishing medium. This product will melt but will not be carried on the surface of water.

 

EXTINGUISHING MEDIA:             Water spray and foam. Water is the best extinguishing medium. Carbon dioxide and dry chemical are not generally recommended because their lack of cooling capacity may permit re-ignition.

 

HAZARDOUS COMBUSTION PRODUCTS: Hazardous combustion products may include intense heat, dense black smoke, carbon monoxide, carbon dioxide, triarylphosphate ester fragments, hydrocarbon fragments and oxides of phosphorus.

7. HANDLING AND STORAGE

 

HANDLING:                                                                                           Follow recommendations on label and in processing guide. Prevent contact with skin and eyes. Use good industrial hygiene practices. Provide adequate ventilation. Secondary operations such as grinding, sanding or sawing may produce a dust explosion hazard. Use aggressive housekeeping activities to prevent dust accumulation; employ bonding, grounding, venting and explosion relief provisions in accordance with accepted engineering practices.

 

STORAGE:                                                                                             Store in a dry place away from moisture, excessive heat and sources of ignition.

 

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

 

ENGINEERING CONTROLS:                                            A continuous supply of fresh air to the workplace together with removal of processing fumes through exhaust systems is recommended. Processing fume condensate may be a fire hazard and toxic; remove periodically from exhaust hoods, duct work and other surfaces using appropriate personal protection. For powders and residual dusts refer to HANDLING AND STORAGE section.

 

Ventilation requirements must be locally determined to limit exposure to processing fumes in the workplace. Design techniques and guidelines may be found in publications such as:

 

Industrial Ventilation; available from the American Conference of Governmental Industrial Hygienists, Committee on Industrial Ventilation, P.O. Box 16153, Lansing, MI 48901.

 

PERSONAL PROTECTION

EYE/FACE:                                                                                        Wear safety glasses with side shields or chemical goggles. In addition, use full face shield when cleaning processing fume condensates from hoods, ducts and other surfaces.

SKIN:                                                                                                When handling pellets avoid prolonged or repeated contact with skin. When melt processing product wear long pants, long sleeves, well insulated gloves and face shield when applicable. Use appropriate protective clothing, including chemical resistant gloves, to prevent any contact with processing fume condensates.

RESPIRATORY:                                                                              When processing fumes are not adequately controlled, use respirator approved for protection from organic vapors and acid gases. When dust or powder from secondary operations, such as grinding sanding or sawing, are not adequately controlled use respirator approved for Protection from dust.

11. TOXICOLOGICAL INFORMATION

 

PRODUCT:

EYE:                                                                                                   Product not considered primary eye irritant. When similar products, in finely divided form, were placed into the eyes of rabbits, slight transient redness or discharge occurred - consistent with the expected slightly abrasive nature of the resin particles.

SKIN:                                                                                                Product not considered primary skin irritant. Draize Skin Primary Irritation Score (rabbit) for similar products, in finely divided form, for a 24-hour exposure is 0. Not expected to be a skin sensitizer based on results of Modified Buehler Guinea Pig Sensitization Test from similar products. Dermal LD50 (rabbit) > 2g/kg, estimated.

ACUTE ORAL:                                                                                 Oral LD50 (Rat) >5 g/kg, estimated.

ACUTE INHALATION:                                                                   Processing fumes from similar products are not considered toxic. In acute inhalation tests, laboratory rats were exposed to processing fumes at concentrations exaggerating those that would likely occur in workplace situations. During the exposure periods (6 hour duration) signs of eye and nasal irritation were observed. These signs of irritation disappeared shortly after the animals were removed from the exposure chamber. No deaths or signs of toxicity were noted during the fume exposure period. There were no distinct or consistent treatment related tissue or organ changes noted in gross necropsies.

 

COMPONENTS:

In two independent 2 year dietary studies, purebred beagles and laboratory rats were fed polyphenylene oxide resin powder (up to 10% by weight in the animal diet). In both studies, there were no adverse effects on physical appearance, behavior, growth, food consumption, survival, clinical laboratory results, organ weights or gross or microscopic pathology. In a 6 month chronic inhalation study, rats and guinea pigs exposed 6 hrs/day to up to 300 mg/m3 PPO dust developed no physical, nutritional, hematologic, clinical or pathological reaction except to lung tissue changes which consisted of macrophage accumulation, many of which were degenerative in the pulmonary alveoli. Polyphenylene oxide is not a mutagen by Ames (Salmonella) Assay with and without activation.

 

The triarylphosphate esters contained in this product have undergone extensive toxicology testing. They are not acutely toxic via oral (LD50's >5 g/kg), dermal (LD50's>2 gfkg), or inhalation (LCSO's >4.14 mg/L) routes of exposure. These triarylphosphate esters may be mild and transient skin and eye irritants and have not been shown to be sensitizers. They produce only minimal systemic effects at relatively high concentrations, consisting primarily of increase in liver and lung weight. The triarylphosphaate were not mutagenic in bacterial and mammalian assays and did not produce chromosomal aberrations in either in vitro or in vivo test systems. In recent acute and delayed neurotaxicity studies in hens, these triarylphosphate esters were not found to be neurotoxic and did not inhibit neurotoxic esterase (NTE) activity. In reproductive and developmental toxicity studies, no adverse effects have been observed. Consistent with aryl phosphates, these substances inhibit plasma acetylcholinesterase (ACHE) and monacyte nonspecific esterase (MNSE). However, when tested in an extensive and validated immunotoxicity testing battery, MNSE staining inhibition showed no adverse effects an immune system function. This staining phenomenon has not been observed at exposures below lOug/m3.
