Maintain a Safe Working Environment with Our Hydrogen Gas Calculator

Ensure that your warehouse has proper ventilation in the motive battery charging area. If the charging area is not well-ventilated, the build-up of hydrogen gas can be hazardous. Hydrogen concentration should be kept below 1% to maintain a safe working environment.

Use the calculator below to determine the vent requirements and fan requirements to maintain a safe level of hydrogen gas concentration.

Step 1: Hydrogen Concentration

No. Cells in Battery
6-Hour Rated Capacity of battery in ampere-hours
Volume of Hydrogen produced during recharge XX

Step 2: Room Volume (for a room with a flat roof)

Room Width (ft.)
Room Length (ft.)
Room Height (ft.)
Total Volume of Room XX

Step 3: Hydrogen Gas Produced per Hour

Volume of Hydrogen XX ft. (Result from Step 1)
Number of Batteries Stored in Room
Hydrogen Gas Produced per Hour Above field is required

Step 4: Ventilation Requirement

Volume of Room XX cubic feet (Result from Step 2)
Hydrogen Gas Produced per Hour XX cubic feet (Result from Step 3)
Max. percentage of hydrogen gas allowed 1% (Industry Standard)
Complete Air Exchange Every XX

Step 5: Fan Requirement

Volume of Room XX cubic feet (Result from Step 2)
Complete Air Exchange Every XX minutes (Result from Step 4)
Fan Requirement XX

Step 6: Percentage of Hydrogen Gas

Hydrogen Gas Produced Per Hour XX cubic feet (Result from Step 3)
Total Volume of Room XX cubic feet (Result from Step 2)
Percentage of Hydrogen Gas .XX
