Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

HAPTOGLOBIN

NFPA

PRODUCT USE

Alpha- 2- globulins which combine with haemoglobin to form a weak peroxidase. Constitute
about 25% of the alph- 2- globulin fraction of human blood. each individual has three
genetic types, each reacting identically with antibodies to each of the others.
Structurally haptoglobulins are glycoproteins occurring as tetramers composed of alpha- ,
and beta- polypeptide chains, the alpha- chains varying in the three phenotypes, with
identical beta- chains

SYNONYMS

alpha-2-globulin, alpha-2-globulin, protein

EMERGENCY OVERVIEW

RISK

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.  

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).  The dust may produce eye discomfort causing smarting, pain and redness.  

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.  Blood and blood-related products can cause the transmission of pathogens and bring up immune reactions. Workers may be exposed to AIDS, hepatitis and other infectious diseases. Immune responses include anaphylaxis and delayed symptoms including itch, chills, fever, fatigue and swollen lymph nodes.  

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.  Use of blood and related products can cause infection and immune reactions. Aerosols containing blood may contain the risk of infection to AIDS, hepatitis and other infectious diseases. Immune responses include anaphylaxis and delayed symptoms including itch, chills, fever, fatigue and swollen lymph nodes.  

CHRONIC HEALTH EFFECTS

  There is some evidence that 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 inhalation of generated dust and skin contact.  Exposure to small quantities may induce hypersensitivity reactions characterized by acute bronchospasm, hives (urticaria), deep dermal wheals (angioneurotic edema), running nose (rhinitis) and blurred vision . Anaphylactic shock and skin rash (non-thrombocytopenic purpura) may occur. An individual may be predisposed to such anti-body mediated reaction if other chemical agents have caused prior sensitization (cross-sensitivity).  Dusts produced by proteins can sometimes sensitize workers like other foreign bodies. Symptoms include asthma appearing soon after exposure, with wheezing, narrowing of the airways and breathing difficulties. There may also be a chronic cough, phlegm, fever, muscle pains, fatigue and airway obstruction; chest X-rays may show a characteristic net-  like pattern or scarring at the tip and base. There may also be chest discomfort, headache, stomachache and a general feeling of unwellness. Often the clinical picture is similar to "farmer's lung" and other allergic lung inflammations. Prolonged contact with the skin can cause pain, redness, inflammation and ulceration. Repeated attacks can cause loss of lung function due to scarring.
