Battery Safety
HNAS Battery Safety Manual
Hazard identification
For the battery cell, chemical materials are stored in a hermetically sealed
metal case, designed to withstand temperatures and pressures encountered
during normal use. As a result, during normal use, there is no physical danger
of ignition or explosion or chemical danger of hazardous materials' leakage.
However, if exposed to a fire, mechanical shock, decomposed, added electric
stress by misuse, the gas release vent will be operated. The battery cell case
will be breached at the extreme. Hazardous materials may be released.
Moreover, if heated strongly by fire, acrid or harmful fumes may be emitted.
Human health effects:
Inhalation
: The fumes may affect the respiratory tract membrane and the
lungs. Fumes may cause a cough, chest pain and dyspnea. Bronchitis and
pneumonia may occur. The fumes could possibly be a carcinogen.
Skin contact
: Skin contact with the electrolyte would seriously affect the skin
and may cause dermatitis.
Eye contact
: The electrolyte leaked from the battery cell is a strong alkali.
When it goes into the eye, the cornea may be affected and it may lead to
blindness.
Ingestion
: Ingestion of the electrolyte would seriously irritate the mouth and
the throat and result in vomiting, nausea, hematemesis, stomach pains and
diarrhea.
