Lithium-Ion Battery Safety: General Industry and Construction

Lithium-ion batteries are now embedded in everyday operations across a wide range of workplaces. They power laptops, radios, cordless tools, forklifts, backup systems, and mobile equipment that keep organizations moving. As battery usage increases, so does the likelihood of a workplace fire. When batteries are damaged, improperly charged, or stored without adequate controls, it can lead to serious injury and property damage.

OSHA frameworks, general industry (manufacturing and nonprofit organizations) under 29 CFR 1910 and construction (active jobsites and field operations) under 29 CFR 1926, best describe how to handle damaged batteries. Though workplace settings differ, safety fundamentals remain the same: proper handling, safe charging, routine inspection, and quick response to damaged batteries.

The primary hazard: thermal runaway

Commercial-grade lithium-ion batteries can store several hundred kWh in a compact space. The energy in these batteries can cause a thermal runaway when exposed to physical damage, overcharging, internal failure, or extreme temperatures. This chain reaction creates intense heat, rapid fire growth, violent venting, and the release of flammable or toxic gases. Lithium-ion battery fires are difficult to extinguish completely and can reignite after the initial event.

General industry under OSHA 1910

In the general industry, lithium-ion batteries are often treated as ordinary conveniences rather than serious hazards. Manufacturing operations typically use them in powered industrial equipment, maintenance tools, scanners, radios, and backup systems. Nonprofit organizations rely on them for office technology, communication devices, emergency equipment, facility maintenance tools, or mobility devices. Since the batteries are woven into everyday routines, risks are underestimated.

Common problems in OSHA 1910 settings include charging in cluttered spaces, use of damaged or aging batteries, reliance on non-approved chargers, poor ventilation, and a lack of designated battery charging or storage areas. These conditions increase the likelihood of overheating, short-circuiting, or unnoticed battery failure.

Employers in the general industry should focus on the following controls:

• Create designated charging areas away from combustible materials and high-traffic spaces.
• Use only manufacturer-approved batteries, chargers, and accessories.
• Inspect batteries regularly for swelling, cracking, leakage, corrosion, unusual odor, or excessive heat.
• Remove damaged batteries from service immediately and isolate them until they can be properly evaluated or disposed of.
• Train employees to recognize warning signs and report concerns before an incident occurs.
• Incorporate lithium-ion battery safety into existing electrical safety, fire prevention, and housekeeping practices.

Construction under OSHA 1926

Construction environments present a different set of lithium-ion battery safety challenges. On jobsites, batteries are commonly used in cordless power tools, temporary lighting, communication equipment, battery-powered heavy equipment, and charging stations set up in trailers, gang boxes, or temporary work areas. Unlike fixed facilities, construction sites are dynamic and often expose batteries to rough handling, weather, and frequent transport.

OSHA 1926 environments increase risk because batteries may be dropped, crushed, exposed to moisture, subjected to heat or cold extremes, or charged through improvised setups. Loose batteries stored with metal objects, damaged packs left in service, and overloaded temporary power arrangements can all create serious ignition hazards.

Construction employers and crews should emphasize these controls:

• Store batteries in cool, dry, secure locations protected from direct sunlight, heat sources, and impact.
• Protect battery terminals during storage and transport to prevent short-circuiting.
• Use charging areas that are stable, orderly, and separated from flammable materials whenever possible.
• Inspect batteries and battery-powered tools before use, especially after drops or visible damage.
• Take damaged batteries out of service immediately and do not attempt makeshift repairs.
• Include lithium-ion battery hazards in toolbox talks, daily planning, and site-specific safety discussions.

Fire prevention and emergency response

Whether the workplace falls under OSHA 1910 or OSHA 1926, fire prevention should remain a central part of any lithium-ion battery safety program. Charging areas should be kept clear of unnecessary combustibles, arranged to prevent overheating, and monitored for signs of battery distress. Where practical, smoke detection and clear access to emergency response equipment should be considered.

If a lithium-ion battery shows signs of smoking, popping, hissing, bulging, or overheating, personnel should keep their distance and follow the site’s emergency procedures. If a fire occurs, evacuate the area, contact emergency services, and only attempt extinguisher use when trained and conditions are safe. Battery fires may continue to smolder or reignite, so post-incident monitoring is important.

Disposal and program management

Improper disposal is another major source of lithium-ion battery incidents. Batteries should never be thrown into ordinary trash containers where they can be crushed, punctured, or exposed to other metals. Used or damaged batteries should be managed through approved recycling or hazardous waste channels, and terminals should be protected before transport or disposal.

A strong battery safety program should include written procedures for charging, storage, inspection, removal from service, emergency response, and disposal. When these elements are built into daily operations, organizations are better prepared to prevent incidents before they escalate.

Final thoughts

Lithium-ion batteries are essential to modern work, but they are not low-risk. In the general industry under OSHA 1910, manufacturing facilities and nonprofit organizations should treat battery charging, storage, and inspection as part of their routine safety management systems. In construction under OSHA 1926, employers must address the added hazards created by movement, impact, weather, and temporary power arrangements.

Across both environments, the message is clear: when a device or tool relies on a lithium-ion battery, it deserves the same level of hazard recognition and control as any other fire or electrical risk. Proactive planning, employee awareness, and consistent procedures can make the difference between normal operations and a serious incident.
