Battery rooms and hydrogen notes
Public OSHA discussion of charging areas often mentions ventilation, no-smoking rules and an eyewash when flooded batteries are watered. Write those as site constraints: room volume, existing exhaust, and whether the factory must include a hood. A charger cabinet quote that stays silent on the room is still a machine-only line.
Nameplate charge current does not prove the room airflow is enough. Keep application load, pack chemistry and watering method on the brief so a substitute high-frequency charger is not compared only on voltage.
