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).
Whether full-time or part-time, employees are entitled to use up to 24 hours or three days (whichever is more) of paid sick leave per year. For example, a part-time employee is typically scheduled to work five hours per day, five days per week.
