Safety Precautions

3. Repairs to sealed components

• During repairs to sealed components, all 

electrical supplies shall be disconnected from 
the equipment being worked upon prior to any 
removal of sealed covers, etc.

• If it is absolutely necessary to have an 

electrical supply to equipment during 
servicing, then a permanently operating 
form of leak detection shall be located at the 
most critical point to warn of a potentially 
hazardous situation.

• Particular attention shall be paid to the 

following to ensure that by working on 
electrical components, the casing is not 
altered in such a way that the level of 
protection is affected. This shall include 
damage to cables, excessive number of 
connections, terminals not made to original 
speci

fi

 cation, damage to seals, incorrect 

fi

 tting 

of glands, etc.

• Ensure that apparatus is mounted securely.
• Ensure that seals or sealing materials have 

not degraded such that they no longer serve 
the purpose of preventing the ingress of 

fl

 ammable atmospheres.

• Replacement parts shall be in accordance 

with the manufacturer’s speci

fi

 cations.

NOTE: The use of silicon sealant may inhibit 
the effectiveness of some types of leak 
detection equipment.
Intrinsically safe components do not have to be 
isolated prior to working on them.

4. Repair to intrinsically safe components

• Do not apply any permanent inductive or 

capacitance loads to the circuit without 
ensuring that this will not exceed the 
permissible voltage and current permitted for 
the equipment in use.

• Intrinsically safe components are the only 

types that can be worked on while live in the 
presence of a 

fl

 ammable atmosphere.

• The test apparatus shall be at the correct 

rating.

• Replace components only with parts speci

fi

 ed 

by the manufacturer. Unspeci

fi

 ed parts by 

manufacturer may result ignition of refrigerant 
in the atmosphere from a leak.

5. Cabling

• Check that cabling will not be subject 

to wear, corrosion, excessive pressure, 
vibration, sharp edges or any other adverse 
environmental effects.

• The check shall also take into account the 

effects of aging or continual vibration from 
sources such as compressors or fans.

6. Detection of 

fl

 ammable refrigerants

• Under no circumstances shall potential 

sources of ignition be used in the searching or 
detection of refrigerant leaks.

• A halide torch (or any other detector using a 

naked 

fl

 ame) shall not be used.

7. The following leak detection methods 

are deemed acceptable for all refrigerant 
systems

• No leaks shall be detected using detection 

equipment with sensitivity to detect leakage 
of 5g/year of refrigerant or better under a 
pressure of at least 0.25 times the maximum 
allowable pressure (>1.04 MPa, max 4.15 
MPa), for example, a universal sniffer.

• Electronic leak detectors may be used 

to detect 

fl

 ammable refrigerants, but the 

sensitivity may not be adequate, or may need 
re-calibration.
(Detection equipment shall be calibrated in a 
refrigerant-free area.)

• Ensure that the detector is not a potential 

source of ignition and is suitable for the 
refrigerant used.

• Leak detection equipment shall be set at a 

percentage of the LFL of the refrigerant and 
shall be calibrated to the refrigerant employed 
and the appropriate percentage of gas (25 % 
maximum) is con

fi

 rmed.

• Leak detection 

fl

uids are also suitable for use 

with most refrigerants, for example, bubble 
method and 

fl

uorescent method agents. The 

use of detergents containing chlorine shall 
be avoided as the chlorine may react with the 
refrigerant and corrode the copper pipe-work.

• If a leak is suspected, all naked 

fl

 ames shall 

be removed/extinguished.

• If a leakage of refrigerant is found which 

requires brazing, all of the refrigerant shall 
be recovered from the system, or isolated 
(by means of shut off valves) in a part of the 
system remote from the leak. The precautions 
in #8 must be followed to remove the 
refrigerant.
