Emergency services responded to an industrial workshop fire in Riverstone, in Sydney’s northwest, after a blaze broke out at a property on Loftus Street. Fire crews were called to the area at about 11:30am after reports of a fire inside a workshop.

The incident prompted a significant emergency response as firefighters worked to contain the blaze and prevent it from spreading to other parts of the industrial property. Crews remained at the scene after the main fire had been brought under control to deal with remaining hotspots and ensure the building was safe.

Three men and a boy were assessed by paramedics for possible smoke inhalation following the fire. They were treated at the scene and did not require transport to hospital for further medical care.

Firefighters were able to largely extinguish the fire by about 1pm, although crews remained at the location for some time while they continued to manage the site. Industrial fires can present additional risks because workshops may contain machinery, fuels, chemicals, electrical equipment and other materials capable of producing intense heat or toxic smoke.

The incident caused concern among people in the surrounding industrial area as emergency crews worked to secure the building. Smoke from a workshop fire can travel quickly through enclosed industrial spaces, making early evacuation and emergency response particularly important.

Authorities have not indicated that anyone suffered serious injuries in the incident. The medical assessment of the four people at the scene allowed emergency responders to determine that hospital treatment was not immediately necessary.

Firefighters are expected to examine the affected premises as part of the response and determine the circumstances surrounding the outbreak. Investigations into industrial fires can involve examining electrical equipment, machinery, storage areas and other possible ignition sources.

The Riverstone incident is another reminder of the risks associated with fires in industrial and workshop environments. Businesses operating from these premises are required to maintain appropriate fire safety arrangements, including accessible exits, suitable extinguishing equipment and safe handling and storage of potentially hazardous materials.

For nearby workers and residents, the emergency response temporarily brought a large number of emergency personnel and vehicles into the area. Authorities may provide further information if the investigation establishes how the fire began or identifies any contributing factors.

The quick response from firefighters helped prevent the blaze from causing more extensive damage or spreading beyond the workshop. While the incident resulted in smoke exposure assessments, no serious injuries were reported among those at the scene.

Further details about the extent of property damage and the cause of the fire may become available as investigations continue.
