Rough outline

1.What are Pneumatic tools / air compressors? Diagram examples of compressors and an explanation. Show a range of different air compressors you might come across.

• A pneumatic tool is one that's driven with the assistance of compressed air rather than electricity. Generally speaking, all pneumatic tools require an air compressor to provide a pressurized burst of air to perform their operation.

Reciprocating compressor	A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.
Ionic liquid piston compressor	An ionic liquid piston compressor, ionic compressor or ionic liquid piston pump is a hydrogen compressor based on an ionic liquid piston instead of a metal piston as in a piston-metal diaphragm compressor.
Rotary screw compressors	Rotary screw air compressors operate by trapping air between two meshed rotors and reducing the volume of that trapped air as it moves down through the rotors. This reduction in volume results in compressed air, which can then be used to power air tools, inflate tires, or in numerous other applications.
Rotary vane compressors	Rotary vane compressors consist of a cylindrical casing, two openings - one suction and one discharge - and a rotor positioned eccentrically with respect to the casing. Compression occurs by refrigerant flowing into the chamber where, due to eccentric rotation, there is a reduction in the desired volume.
Rolling piston	Construction and Working of Stationary Blade Type (Rolling Piston) Rotary Compressor. Figure shows a single stationary blade rotary compressor. In this type, a roller (impeller) is fixed on an eccentric shaft rotates in a stationary cylinder. The shaft is run off-centre so that roller rolls around the cylinder wall.
Scroll compressors	A scroll compressor has one fixed scroll which remains stationary and another moving or orbiting scroll that rotates through the use of a swing link. When this happens, the pockets of refrigerant between the two scrolls are slowly pushed to the center of the two scrolls, causing the reduction of the volume of the gas.
Diaphragm compressor	A diaphragm compressor is a variant of the classic reciprocating compressor with backup and piston rings and rod seal. The compression of gas occurs by means of a flexible membrane, instead of an intake element. The back and forth moving membrane is driven by a rod and a crankshaft mechanism
Air bubble compressor	An air compressor is a pneumatic device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). ... When tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank

2.Safety when using an air compressor. Dangers and hazards , preventive action and servicing.

1. Use Gas Air Compressors Outdoors. Unless it's powered electrically, you should always use an air compressor outdoors.

2. Wear Safety Goggles and Gloves. 

3. Use a Self-Retracting Cord. 

4. Use an OSHA-Approved Nozzle. 

5. Check for Oil and Air Leaks. 

6. Follow Manufacturer's Recommended Maintenance.

3.PPE when using air tools - general

• Eye protection is required, and head and face protection is recommended for crew members working with pneumatic tools. Gloves should be worn when using pneumatic tools to protect your hands. Dust masks should be used when using tools that create dust and fumes in the work area that may be hazardous.

5.Specific safety when using

Impact driver - Always wear safety glasses with side protectors when using an impact driver. Never wear a tie, loose clothing, a watch, rings, or jewelry when using an air-impact wrench. wrench. Only use impact wrench sockets that are specifically designed for this type of tool.

Air ratchet - Do not operate the tool at a pressure above the manufacturer's rating. Wear safety glasses or a face shield, safety shoes or boots, and hearing protection. Set up screens or shields in areas where nearby workers may be exposed to flying fragments, chips, dust, and excessive noise.

Dust off gun - The nozzle pressure must remain below 10 psi (69 or 70 kPa) and personal protection equipment (PPE) must be worn to protect the worker's body, especially the eyes, against particles and dust under pressure. Use effective guarding methods that prevent a chip or particle (of any size) from being blown into the eyes or unbroken skin of the operator or other workers nearby. You may also use barriers, baffles, or screens to protect other workers near the operator if there is a risk of exposure.

Air riveter - When using a rivet gun or air hammer, always install a safety clip or retainer in order to prevent the set from being ejected during operation. Never point rivet guns toward anyone or "dead-end" them against yourself or anyone else. Noise is another issue associated with pneumatic tools.
