Yes - Fire extinguishers are a fundamental legal and safety requirement in commercial and industrial environments and are strongly recommended in all occupied buildings as the first line of fire defence.
Fire detection systems are often required based on building regulations, occupancy classification, fire risk, insurance requirements, and the size and use of the building. In many cases, larger or higher-risk buildings (commonly from approximately 500m² and above, depending on layout and occupancy) are required to have an approved fire detection system installed.
Fire sprinkler requirements in South Africa are not based on a single fixed size rule. They are determined by SANS 10400-T regulations, fire risk classification, building occupancy, municipal fire approval, engineering design requirements, and insurance conditions. In many large, high-risk, or complex buildings, sprinkler systems are required as part of compliance and life safety design.
For fire detection systems, gas suppression systems and fire equipment, personnel are required to be SAQCC certified and registered in order to inspect, test, commission, and certify systems for compliance.
Sprinkler systems, personnel are required to be appropriately qualified, trained, and competent in sprinkler system design, installation, and maintenance, with work carried out in accordance with applicable standards, regulations, and industry requirements to ensure full system performance and compliance.
In addition, a non-ASIB approved installer is not permitted to work on ASIB-rated client systems where compliance with ASIB standards is required.
A fire extinguisher loses pressure mainly due to small leaks, worn seals, corrosion, temperature changes, or lack of maintenance over time.
It can lose pressure, have the powder compact or settle (making it ineffective), become blocked, corrode internally, and fail to discharge properly in an emergency.
Fire extinguishers are typically serviced once every 12 months, while fire detection and gas suppression systems are generally serviced every 6 months, depending on applicable standards, risk level, and insurer requirements.
Sprinkler systems are typically inspected monthly for basic visual and operational checks, and formally inspected and tested every 6 months with a valve overhaul every 3 years.
A fire pump should be checked and run weekly to ensure correct operation, with a full overhaul and annual service carried out to confirm performance, reliability, and compliance with system requirements.
All testing, servicing, and maintenance should be performed by a competent and appropriately qualified ASIB technician.
Each sprinkler head is fitted with a heat-sensitive glass bulb that contains a liquid designed to expand when exposed to heat. Sprinklers are manufactured with different activation temperatures, typically ranging from 68°C to 260°C, with the temperature indicated by the colour of the glass bulb.
When the surrounding temperature reaches the rated activation level, the liquid in the bulb expands until the glass shatters, allowing water to discharge from the sprinkler head. The system then releases water directly over the fire area to control or suppress the fire at its source.
Fire sprinklers operate only in response to heat at the sprinkler head location, activating individually to target the affected area and limit fire spread.
