Hazardous Materials and Fire Safety Definitions
Combustible Dusts, Fibres, and Liquids
The OBC defines combustible dusts as particles liable to produce explosions, while combustible fibres include loose vegetable or animal fibres (like hemp or wool) that present flash fire hazards. Combustible liquids are specifically classified as those with a flash point between 37.8°C and 93.3°C.
Compressed Gas and Dangerous Goods
Materials regulated as compressed gas meet specific vapour pressure thresholds at set temperatures. Dangerous goods are those regulated by the Transportation of Dangerous Goods Regulations or classified under Hazardous Products Regulations, requiring specialized handling by your contractor.
Building Spaces and Structural Requirements
Conditioned Space and Computer Rooms
A conditioned space is any area where temperature is controlled to limit variation from exterior temperatures. Computer rooms are specialized environments for electronic data equipment with strict occupant load limits (max 1 person per 40 m²) and self-contained climate control systems.
Structural Foundations and Loads
Understanding the dead load—the weight of all permanent structural components—is critical for safety. For challenging terrain, a deep foundation (such as piles) is utilized to transfer loads to soil or rock at significant depths.
Plumbing and Specialized Structures
Continuous Vents and Dead Ends
In plumbing, a continuous vent extends a vertical section of a drain, whereas a dead end refers to a pipe terminating with a closed fitting. Ensuring these are installed correctly prevents back-siphonage at the critical level.
Demountable Stages and Day Camps
Specialized structures like demountable stages are designed for temporary events and must be capable of being dismantled. A day camp is defined by its continuous operation period not exceeding 24 hours.
