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).
