Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

UNIROYAL CELOGEN 754A

NFPA

PRODUCT USE

Foaming agent, blowing agent used to produce low density foamed materials; particularly
plastics; PVC, Polyethylene. Incorporated at low temperatures and then heat processed to
produce foam. Additives may reduce blowing temperature. Gas evolved in " blowing" is
flammable when concentrated.

EMERGENCY OVERVIEW

RISK

Contact with acids liberates toxic gas.
May cause SENSITIZATION by inhalation.
Flammable.
Repeated exposure may cause skin dryness and cracking.

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Although ingestion is not thought to produce harmful effects, the material may still be damaging to the health of the individual following ingestion, especially where pre-  existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality (death) rather than those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificant quantities is not thought to be cause for concern.  Considered an unlikely route of entry in commercial/industrial environments.  

EYE

  Although the material is not thought to be an irritant, direct contact with the eye may produce transient discomfort characterized by tearing or conjunctival redness (as with windburn).  

SKIN

  The material is not thought to produce adverse health effects or skin irritation following contact (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.  Prolonged or repeated skin contact may cause.  in some cases, sensitization.  Sensitization may result in allergic dermatitis responses includingrash, itching, hives or swelling of extremities.  The material may accentuate any pre-existing skin condition.  

INHALED

  The material is not thought to produce adverse health effects or irritation of the respiratory tract (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable control measures be used in an occupational setting.  Respiratory sensitization may result in allergic/asthma like responses; from coughing and minor breathing difficulties to bronchitis with wheezing, gasping.  Inhalation of vapor may aggravate a pre-existing respiratory condition such as asthma, bronchitis, emphysema.  Sensitization reactions may appear suddenly after repeatedsymptom free exposures.  

CHRONIC HEALTH EFFECTS

  Inhaling this product is more likely to cause a sensitization reaction in some persons compared to the general population.  

  Principal routes of exposure are usually by skin contact with the material and inhalation of generated dust.  Prolonged or repeated skin contact may cause drying with cracking,irritation and possible dermatitis following.  Sensitization may give severe responses to very low levels of exposure, i.e. hypersensitivity. Sensitized persons should not be allowed to work in situations where exposure may occur.  Exposures at 2-5 mg/m3 in azodicarbonamide manufacture caused  sensitisation  and asthma. Workers symptoms ceased on removal from exposure.  [Thorax 1981, vol 36, p906-909].
