Compressed Air Safety Training Reviews

Example of correct answer below: Question How are compressors typically classified? Compressors are typically classified based on how they compress air or gas, and their construction or application. Here's a breakdown of the most common classification methods: ⚙️ 1. By Principle of Operation Type Description Positive Displacement Compressors Trap a fixed volume of air and mechanically reduce its volume to increase pressure. Examples: Reciprocating (piston), rotary screw, rotary vane Dynamic Compressors Use rotating impellers to accelerate air and convert velocity into pressure. Examples: Centrifugal, axial flow compressors 🧱 2. By Construction Type Description Reciprocating Uses pistons driven by a crankshaft—common in garages and small workshops Rotary Screw Uses two intermeshing screws—ideal for continuous industrial use Rotary Vane Uses a rotor with sliding vanes—compact and efficient for moderate air needs Centrifugal High-speed impellers—used in large-scale industrial or HVAC systems Axial Air flows parallel to the shaft—used in jet engines and power plants 📏 3. By Pressure Range Pressure Type Output Pressure Low-Pressure Up to 150 psi (10 bar) Medium-Pressure 151–1,000 psi (10.4–68.9 bar) High-Pressure Above 1,000 psi (69 bar) 🧰 4. By Application or Medium Oil-lubricated vs. Oil-free Portable vs. Stationary Industrial, medical, refrigeration, or pneumatic tools

This is very important as it covers kinetic energy, the kinds of air involved and the purposes including the dangers of compressed air.

Perhaps more could have been said about not using them to clean off dusty clothes. Maintenance would normally be carried out by a maintainer not necessarily the user. I felt too much emphasis was put on this side of the course.
