The use of a quantity of material in an unventilated or confined space may result in
increased exposure and an irritating atmosphere developing.Before starting consider
control of exposure by mechanical ventilation.
Heating may cause an explosion.
Accidental ingestion of the material may be damaging to the health of the individual. Azides, if swallowed, can cause breathlessness and rapid heart beat within 5 minutes. Nausea, vomiting, headache, restlessness and diarrhea can occur within 15 minutes. Other symptoms include low blood pressure which cannot be corrected, abnormal breathing, reduced body temperature, reduced blood pH, convulsions, collapse and death. Continued administration can cause increased sensitivity. Poisoning can cause headaches and acidosis. Several grams of sodium azide can cause liver, pulmonary and brain swelling with death occurring in less than an hour. Large doses of azide increases the blood pressure and causes generalized convulsions, followed by depression and collapse.
Although the liquid 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 contact with the material may damage the health of the individual; systemic effects may result following absorption. The material is not thought to be a skin irritant (as classified using animal models). Temporary discomfort, however, may result from prolonged dermal exposures. Good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting. Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.
Inhalation may produce health damage*. Inhalation of vapors or aerosols (mists, fumes), generated by the material during the course of normal handling, may be damaging to the health of the individual. There is some evidence to suggest that the material can cause respiratory irritation in some persons. The body's response to such irritation can cause further lung damage. Azide vapors are irritating and cause bronchitis and lung edema. If inhaled, sore throat, cough, dizziness, shortness of breath and fainting can result. Inhalation can result in similar symptoms as ingesting the substance. Other effects include eye irritation, headache, low blood pressure and collapse. Blindness, rigidity, liver and brain damage is possible. The use of a quantity of material in an unventilated or confined space may result in increased exposure and an irritating atmosphere developing.Before starting consider control of exposure by mechanical ventilation.
Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems. Workers exposed chronically to hydrazoic acid ( produced in aqueous solutions of sodium azide ) frequently complain about headache. Rapid falls in blood pressure can also result.
