It is common knowledge that lead-acid batteries release hydrogen gas that can be potentially explosive. Battery rooms must be adequately ventilated to prohibit the build-up of hydrogen gas. During normal operations, off gassing of the batteries is relatively small. However, the concern is elevated during times of heavy recharge of the batteries, which occurs immediately following a rapid and deep discharge.

Often HVAC designers underestimate the worst case for dangerous hydrogen accumulation, and display reassuring calculations proving that no danger really exists. But dismissing such a critical safety issue is not a prudent or responsible way to deal with it. Instead, we should be prepared to face the likely possibility of hydrogen build up, clearly identify the conditions when the risk is highest, and design systems that protect against explosive levels in a fail-safe way.

This 4-hour course describes the hazards associated with batteries and highlights those safety features that must be taken into consideration when designing, constructing and fitting out a battery room. The course is for reference only. Anyone involved in the design of a battery room should rely on the experience of a professional engineer who is well versed in applicable codes, standards and regulations for the installation site. Advice on specific ventilation rates required must be sought from the battery suppliers.

Specific Knowledge or Skill Obtained

This course teaches the following specific knowledge and skills:

  • The construction, function and operation of a Lead Acid battery
