The Following Presentation is a Guide to Your Safety !!

You are obliged by law to understand and adhere to national and local safety legislation and regulations.


CAUTION:

Work on a compressor unit must only be carried out by authorized service personnel who are fully trained and competent in:

11 Pneumatic SafetyPneumatic Safety



1. Isolate Compressor From System

It is advisable to use an Isolation Notice so people are aware that work is being carried out.



2. Depressurize Compressor and Pipe Work



3. Check that compressor pressure gaugereads zero


Beware !!!

Air Exhausting to Atmosphere can be Dangerous….

Direct Discharge Air Away from the Unit & Operator

Clear Area of any Flying Hazards Before Discharge

Use Hearing Protection During Any Depressurization

Follow All Site / Local Regulations



2 Electrical Safety


22 Electrical SafetyElectrical Safety

1. Isolate From Main Supply2. Remove Fuses3. Lock Out4. Test For Incoming Power

Only when absolutely necessary should any testing be performed with the power on. Use extreme care !

Never work on a powered or running unit alone!


22 Electrical SafetyElectrical Safety

Isolate from Main Supply

Isolate the compressor unit from the main power supply.


22 Electrical SafetyElectrical SafetyRemove Fuses

As an extra safety measure, remove fuses from the power supply to the compressor (and keep safely in your pocket).


22 Electrical SafetyElectrical SafetyLock Out….

Isolate the compressor’s power supply at the main board.

Cover and lock the isolation box to prevent someone inadvertently switching supply back on whilst work is in progress or the unit is unsafe to use.

It is advisable to use an Isolation Notice so people are aware that work is being carried out.


22 Electrical SafetyElectrical SafetyTest for Incoming Power….

Double check that the main supply terminals to the machine are not live before proceeding with any work.

You may be 100% sure that supply has been isolated, but mistakes can occur from time to time. Get into the habit of double checking that the machine is safe to work on as high voltages can kill. It’s not worth the risk !!!

2.2. Calibrated EquipmentCalibrated Equipment

3.3. Lifting EquipmentLifting Equipment


Always use correct tools for the job

Using incorrect tools can damage components and make further maintenance difficult and costly.

e.g.Always use correctly sized spanners, never use grips or adjustable spanners.



Always use equipment that has been correctly tested and calibrated.

Using un-calibrated equipment may give false readings which could give rise to inaccurate fault diagnoses.



Where required always use suitablelifting equipment

Make sure that:-Items being lifted are well secured

The lifting equipment and tackle is in good order and capable of lifting the item.

Nobody, including yourself, stands too close or beneath items that are lifted.

Observe All Posted Signs and Notices


66 General Safety….General Safety….

If testing is required with unit running:-

Ensure all guards are in place.

Be aware of any items that may come in contact with moving parts.

Don’t wear long hanging cloths, neck ties

Do not play with compressed air

Do not point air hoses at anyone

Do not use compressed air to blow dirt from clothing

The following slides give brief descriptions of some of the most commonly used safety signs on CompAir compressors.



Attention:

Only lubricate the system while the motor is running. For further details, see the operating instructions



Warning:

Don’t attempt any servicing / maintenance without reading the manual first.



Attention:

Replace oil filter cartridge after approximately 100 operating hours. For further details, see the operating instructions.



Caution:

Hot Surfaces, Do Not Touch



Caution:

Hot and dangerous exhaust fumes



Warning:

Check and, if required, re-tighten connection terminals. For further details, see the operating instructions.



Earthing Point



WarningPressurized part or system



Warning:

Risk of electric shock



Warning:

The system continues to run for 30 seconds after pressing the ‘O’-Key



Warning:

This system can start up by means of a remote control or automatically after a power failure.



Caution:

Pressure Vessel



Warning:

General Warning



Warning:

Rotating Machinery



Do not re-engage starter until all moving parts are stationary



Never attempt to operate the machine without the safety device mounted.



Carefully read the operating manual before commissioning or servicing this compressor.



Never operate the unit with open doors or loose access panels



Never breathe in compressed air from this system



Caution:

Vessel is pressurized



Caution:

Do not start machine until……

Usually accompanied with another graphic



Wait at least half an hour before proceeding



Condensate drain from after-cooler or from after-cooler with subsequent filtering.



Sound levels:- (needs checking )There are two action levels for continuous noise:-

Ear protection should be provided if requested when noise levels are between 80-85 dB(A)

Ear protection must be provided and their use enforced for anyone exposed to noise levels above 85dB(A)



Safety relief valve setting



Tie down point



Lifting point



Fork Lift points



Protect the generator from moisture.

Do not clean with a Water / Vapor jet



Bleed water from the pressure vessel after every 24 operating hours or if the water ratio is too high.
