Hayward Explosion Leaves Several Injured

ALCO Deputy Fire Chief

What Workers and First Responders Need to Know About Burns, Trauma, and Workers’ Comp Rights

On Thursday morning (Dec 11, 2025), emergency crews rushed to the 800 block of Lewelling Blvd. in Hayward, California, after reports of a possible explosion followed by a structural fire. Early footage showed heavy smoke, firefighters on scene, and several individuals being placed on stretchers.

Authorities have now confirmed that six people were injured, with two of them being workers who were reportedly on-site during the incident. The extent of the injuries remains unknown, and several victims were seen being transported on stretchers for medical care. 

Early findings suggest that a construction crew accidentally struck an underground gas line while digging, causing a violent release of gas that may have ignited moments later. PG&E stated that the damaged line was located directly beneath the work zone on Lewelling Blvd., adding complexity to an already tragic situation.

As firefighters worked to contain the scene, the situation highlighted a reality many forget until tragedy strikes: unexpected injuries at work can happen anywhere, at any time, and often without warning.

Unexpected Workplace Injuries: A Real and Immediate Risk

Incidents like today’s remind us that danger is not limited to “high-risk” jobs. Whether you’re a construction worker, warehouse employee, retail worker, or delivery driver, accidents can occur in seconds, and the injuries can be severe.

Common unexpected workplace injuries include:

  • Burns from fire, explosions, electrical malfunctions, or chemicals

  • Crush injuries caused by structural collapse or heavy machinery

  • Smoke inhalation

  • Traumatic injuries such as fractures, concussions, or spinal damage

First responders, especially firefighters, face even greater risks. Burns, heat exposure, collapsing structures, and toxic fumes are all part of their daily reality and when they get hurt, they deserve the same legal protections as any other California worker.

How Workers’ Compensation Protects Injured Workers in California

In California, any employee injured on the job (including firefighters) is legally entitled to workers’ compensation benefits, regardless of who was at fault.

Workers’ comp may cover:

  • All medical treatment related to the injury (ER visits, surgeries, rehab, medications)

  • Temporary disability payments while you cannot work

  • Permanent disability benefits, if the injury affects your long-term abilities

  • Reimbursement for transportation to medical appointments

  • Job protections, such as the right to seek treatment and report injuries without retaliation

But many injured workers don’t realize that insurance companies often delay, deny, or undervalue claims, especially in complex cases involving burns, crush injuries, or multi-employee incidents.
That’s why getting clear information and proper representation can make all the difference.
