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).
In California, paid sick leave generally accrues at a rate of one hour per 30 hours worked. 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. She has accrued 24 hours of paid sick leave and takes three scheduled days off. In this case, the employee has used 15 hours (three five-hour workdays) and she can still use an additional nine hours that year.
