Authorities issue a public hazard warning after a fire breaks out inside a chemical analysis laboratory at a metal factory in Balcatta. The fire produces potentially dangerous smoke that spreads beyond the facility, prompting concern among nearby residents. Local emergency services respond to the incident and manage the situation at the factory site. A warning is released to inform the public about the possible effects of the smoke and to encourage people in the surrounding area to take appropriate precautions. The incident is described as occurring within the factory’s chemical lab, where chemicals are used for testing or analysis. Both outlets report the same sequence of events: the fire inside the lab, the creation of potentially hazardous smoke, and the subsequent hazard warning issued to the public in response to the smoke moving through the suburb. The reports do not provide additional details such as injuries, the cause of the fire, or the extent of damage.
