Equipment and Secondary Dust Explosions in Buildings Examples of process equipment explosion scenarios include dryer explosions involving particulate clouds or hybrid vapordust mixtures ignited by overheated often smoldering dust layers blender explosions ignited by by the automatic sprinkler system inside the dust collector
Queenslands construction industry has one of the largest groups of silica exposed workers in the state and just because it has been a risk to workers for a long time does not mean it can be ignored Silica can lead to lung diseases such as silicosis lung cancer obstructive lung disease bronchitis asthma and loss of respiratory volume
Safe Work Practices Procedures Instruction Occupational Silica Dust Exposure Control Plan Sonic Drilling Ltd recognizes that exposure to silica dust can cause silicosis a deadly lung disease and may cause lung cancer Sonic Drilling Ltd takes responsibility
Many dust collecting systems involve an assembly of dust collection equipment such as overhead ductwork capture arms and suction hoods which hang over the workspaces where dust is formed and a central suction unit which pulls the air into one or more dust collectors
Batch weigh systems for lossin weight allow batching operations that are accurate to one pound or less. Selfcontained dust control collection system maximizes dust protection and minimizes lost product. These units require half the space and cost less than standalone units.
