While a rough visual inspection can be carried out every 30 days, you will also need servicing and comprehensive testing every year. Depending on the type of extinguisher and standards, the recurrence of services may vary as follows:

Type of extinguisher Basic service Extended service Overhaul
Water-based Once every 12 months Every 5 years NA
Powder Once every 12 months Every 5 years NA
Powder-primary sealed Once every 12 months Every 10 years NA
Clean agent Once every 12 months NA Every 10 years

According to standards laid down by fire extinguisher organizations, visual inspections for portable extinguishers are imperative to be conducted by owners or professionals. This must be repeated every 30 days and does not require much professional experience. Visual inspections ensure simple obligations and requirements like the stability and the position of the extinguisher in the designated location. It helps ensure that explicit damage is out of reach and the area surrounding the can is free from obstructions for easier access.

Homeowners are required to look for visually obvious signs like physical obstructions, damage, corrosion, dents, and leakage. They are also responsible for analyzing the pressure gauge and ensuring that the indicator is well within the operating range. Another responsibility is ensuring the pull-pin and the seal are perfectly placed. Additionally, you can also verify the last inspection date and maintain a monthly visual inspection log.

2. Maintenance Inspections – Once A Year

Maintenance inspections, as can be told from the name, are a thorough examination, analysis, and repair procedure from the inside out. Employers and homeowners are obligated to conduct a complete maintenance and service check for their extinguishers on a yearly basis. This will ensure all the repair and inherent damage is taken care of.

Annual maintenance inspections are not to be handled by common folk and must be undertaken by a professional fire protection company or an EET/PAT testing company. EET encompasses the professional inspection of portable electric equipment up to 400V and contacting a reliable fire alarm and fire extinguisher testing company to ensure that appliances comply with IET codes for practice. They are equipped with industrial experience and compliance with regulations worldwide.

They are equipped with professional tools, trained skill sets consistent with contemporary compliance procedures, and can accurately detect and correct hazardous situations. The annual maintenance is verified through a dated inspection tag. The government requires EET testing to be conducted by qualified engineers and expert teams covering the work scope needed.

3. Internal Maintenance Inspection – Every 5, 6, Or 12 Years

Apart from third-party inspections, it is also necessary to carry out internal maintenance from the fire protection company. This included discharge and internal examination, along with recharging prospects. Doing so will ensure that all components are well-equipped and in working condition. The recurrence depends on the type of extinguisher. For instance, dry-chemical portables require a 12-year hydrostatic test with a 6-year internal examination. Hydrostatic tests are obligatory for vouching for their integrity and safety to expel the agents under the circumstances.

Pressurised water, wet chemicals, and carbon dioxide extinguishers must be conducted every 5 years, while dry chemical ones may need one every 12 years. Comprehensive testing not only meets the requirements laid down for fire scenarios but also guarantees safety.
