NFPA 855 recommends that a UL 9540A ( ANSI/CAN/UL, 2019) test be used to evaluate the fire characteristics of an ESS undergoing thermal runaway for explosion control safety systems. An approach to determine a flammable battery gas source term to design explosion control systems has been developed based on UL 9540A or similar test data.
Ventilation systems for stationary batteries must address human health and safety, fire safety, equipment reliability and safety, as well as human comfort. The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration.
The employer must know, document and train the employee for the assigned task and exposed risks. It is a requirement to have all the documentation in place prior to authorized personnel entering a battery room to perform a specific work task on a battery system under normal operating conditions.
The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration. Flooded lead-acid batteries must be provided with a dedicated ventilation system that exhausts outdoors and prevents circulation of air in other parts of the building.
A battery explosion is usually caused by the misuse or short-circuit malfunction of a battery. Other related hazards. There are two major electrical hazards in connection with the battery work, namely, electric shock and short-circuit of live electrical conductors.
There is always a possibility of explosion by arcing/sparking around the battery terminals due to Hydrogen and Oxygen presence from the charging process, acid burns, spillages, overcharging and toxic fumes. Under extreme conditions, certain types of batteries can explode violently.
