How frequently should fire extinguishers be manually inspected when conditions are harsh or hazardous?

Fire extinguishers should be manually inspected daily or weekly in harsh or hazardous conditions to ensure they are fully operational and ready for use at a moment's notice. In environments where the potential for fire hazards is elevated—such as construction sites, chemical plants, or facilities with flammable materials—regular inspection is critical. This frequency allows technicians to detect any damage, ensure that extinguishers are not obstructed, and confirm that they are maintained properly in accordance with safety regulations.

Daily or weekly inspections help in quickly addressing any issues, such as a discharge or pressure loss, that could render an extinguisher ineffective when needed. Routine checks also promote a culture of safety within the workplace, ensuring that all employees are aware of the fire safety measures in place. In contrast, longer intervals, such as monthly or yearly inspections, may not provide adequate protection in environments where immediate responsiveness to fire hazards is necessary.
