Immediately flush with water for at least 15 minutes. Seek medical             
attention. If clothing, shoes and/or jewelry come in contact with the

lose consciousness, person should be moved to fresh air at once and seek       
medical attention immediately. If breathing has stopped, artificial            
respiration should be given immediately. In all cases, ensure adequate         
ventilation and provide respiratory protection before he person returns to     
work.

Signs, Symptoms and Effects of Exposure                                        
Inhalation                                                                     
Acute: Inhalation of this material is irritating to the nose, mouth, throat    
and lungs. It may also cause burns to the respiratory tract with the           
production of lung edema, which can result in shortness of breath,             
wheezing, choking, chest pain, and impairment of lung function.                
Inhalation of high concentrations can result in permanent lung damage.         
Chronic: Repeated inhalation exposure may cause impairment of lung function    
and permanent lung damage.

Acute: Dermal exposure can cause severe irritation and/or burns characterized  
by redness, swelling and scab formation. Prolonged skin exposure may cause     
destruction of the dermis with impairment of the skin at site of contact       
to regenerate.                                                                 
Chronic: Effects from chronic skin exposure would be similar to those from     
single exposure except for effects secondary to tissue destruction.

Severe irritation and/or burns can occur following eye exposure. Contact may   
cause impairment of vision and corneal damage..

Acute: Irritation and/or burns can occur to the entire gastrointestinal tract, 
including the stomach and intestines, characterized by nausea, vomiting,       
diarrhea, abdominal pain, bleeding, and/or tissue ulceration.

Carcinogenicity                                                                
Sodium hypochlorite has been shown not to be carcinogenic in laboratory        
animals.                                                                       
It is not included as a carcinogen by IARC, OSHA, NTP, or EPA. IARC has        
concluded that there is inadequate evidence for the carcinogenicity of         
hypochlorite salts in laboratory animals and there is no data available        
from studies in humans.                                                        
Therefore, IARC considers hypochlorite salts to be not classifiable as to      
their carcinogenicity to humans.                                               
Mutagenicity                                                                   
Sodium hypochlorite has been shown to produce damage to genetic material when  
tested in vitro. Studies in vivo have shown no evidence of mutagenic           
potential for this material. Chemicals with potent biocidal activity,          
typical of hypochlorite compounds, may compromise the integrity of many of     
the treated cells, which remain viable during an in vitro assay. This result   
would likely produce cellular changes giving rise to a response indicative of  
mutation. It is judged that the risk of genetic damage is insignificant for    
sodium hypochlorite because of its biocidal activity, lack of mutagenicity     
in vivo, and failure to produce a carcinogenic response.
