Acute Health Effects

Inhalation:  Short Term Exposure- Causes burns. Causes difficulty in breathing, low blood pressure, sleepiness, cyanoderma and pulmonary congestion. If enough is inhaled it can cause lung edema after the latent period of 5-72 hours. Symptoms such as pressure of the chest, difficulty in breathing cyan derma, sleepiness and so forth appear. Symptoms may develop into a fast and slow pulse, low blood pressure and concentration. wet rale 

Long term Exposure- In addition to short-term effects. cause indigestion. Continuous and repetitive exposure according to exposure degree and continuous time cause an inflammation and ulcer of the mouth and a disease of the bronchus and gastrointestinal tract 

Skin contact: Short Term Effects- Burns. Causes severe pain, burns and a brown scaring. The decayed region becomes smooth and necrotized like gelatin and damage to the skin may be severe.

 Eye contact: Short Term Exposure- Causes a burn. Additionally causes damage to eye. Direct exposure toa solid or liquid may cause severe pain and burns. Damage degree differs according to concentration and the exposure time. Causes edema, destruction of epithelial cell, turbidity of the cornea and iritis. If the damage is not serious the patient will gradually recover. In a case of a server burn, damage degree immediately appears. As a complication edema, vascularization, corneal cicatrix, loss of sight, staphyloma, cataracts, symblepharon may appear

Long Term Exposure- Same as reported effect on short term Exposure. Damage degree differs according to concentration and the exposure time. repetitive and continuous exposure to steam or dust causes conjunctivitis  

Ingestion: Short Term Exposure- If swallowed it is harmful and causes burns. Additionally causes vomiting diarrhea and a stomach-ache. Fatal dose for a rat is 273 mg 

Causes severe pain, vomiting, diarrhea and a symptom of collapse. If a patient would not die with 24 hour, recovery takes 2-4 days and will suffer from sudden stomach ache indicating perforation of the stomach and esophagus abdominal tetany and reduction of blood pressure 

Long Term Exposure- May show the same symptoms as short term exposure, repetitive swallowing depending on concentration will cause similar to acute symptoms
