1 During charging, lead acid batteries produce hydrogen and oxygen gases (highly flammable/explosive) as electrolysis occurs.  Many lead acid explosions are believed to occur when electrolytes are below the plates in the battery and thus, allowing space for hydrogen/oxygen to accumulate.
Under the accrual method, employees will earn at least one hour of paid leave for every 30 hours worked. That works out to a little more than eight days a year for someone who works full time. But employers can limit the amount of paid sick leave you can take in one year to 24 hours (three days).
(b) If an employee has already used 480 hours (12 administrative workweeks) of sick leave to care for a family member with a serious health condition, he or she cannot use an additional 104 hours (13 workdays) in the same leave year for general family care or bereavement purposes.
