A fire or a dust explosion is caused if three conditions are met: combustible dusts, air and an ignition source, (explosions also require confinement and material disbursement into the air). If these conditions occur, a fire may occur. The removal of one of these conditions will greatly reduce the risk of a fire or explosion.
An extinguishing system which is primarily based on inert gases, such as CO 2 or nitrogen, in enclosed spaces presents a risk of suffocation. [3] Some incidents have occurred where individuals in these spaces have been killed by inert gas release. When installed according to fire codes the systems have an excellent safety record.
Across Oceania, the following standards outline the requirements, test methods, and performance criteria for fire detection control and indicating equipment utilised in building fire detection and fire alarm systems: Australia AS 1603.4 (superseded), [9] AS 4428.1 (superseded), [10] and AS 7240.2:2018.

Essential Oils: Essential oils can cause pneumonia if inhaled (e.g., diffuser or plug-in air freshener) and liver damage if ingested. Different types of oils have different levels of toxicity, so ...
Smoke detector mounted on a ceiling. A smoke detector is a device that senses smoke, typically as an indicator of fire.Smoke detectors/Alarms are usually housed in plastic enclosures, typically shaped like a disk about 125 millimetres (5 in) in diameter and 25 millimetres (1 in) thick, but shape and size vary.
Standpipes are installed in most large, multistory buildings. There are two types of standpipes: dry and wet. Most standpipes are dry systems and cannot be used by the public. Dry systems require a fire engine to pump water into the system. Most dry systems do not have pre-connected hoses and require firefighters to bring in the hose.
An aspirating smoke detector (ASD) is a system used in active fire protection, consisting of a central detection unit which draws air through a network of pipes to detect smoke. [1] The sampling chamber is based on a nephelometer that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber.
Air fresheners from Febreze. Air fresheners are products designed to reduce unwanted odors in indoor spaces, or to introduce pleasant fragrances, or both. They typically emit fragrance to mask odors but may use other methods of action such as absorbing, bonding to, or chemically altering compounds in the air that produce smells, killing organisms that produce smells, or disrupting the sense of ...
