HAZARDS associated with REFRIGERATING SYSTEMS and refrigerants

These H ZA DS are as ociated es ential y with the ph sical an c emical c aracteristic of

ref rigerants as wel as the pres ures an temp ratures oc ur in in ref rigeration c cles

Inadeq ate precaution may res lt in:

– comp nent rupture or explosion, with ris of projecti es;

– es a e of ref rigerant with the ris of en ironmental damage or toxicity d e to a f racture, a

le kage cau ed by b d desig , in or ect o eration, an inadeq ate maintenan e, re air,

c argin or disp sal;

– burnin or combu tion of the es a in ref rigerant with con eq ent ris of f ire in lu in the

ris of toxic prod cts of combu tion f rom non-FLAMMABLE RE RIGER NT

Ref rigerants, their mixtures an combination with oi s, water or other materials, whic are

present in the RE RIGER TING SYS EM, inten ed or u inten ed, af f ect the internal s r ou din

materials c emicaly an ph sical y f or example d e to pres ure an temp rature They can, if

they have detrimental pro erties, en an er p rson , pro erty an the en ironment directly or

in irectly d e to glo al lon term ef fects (ozone de letion p tential, glo al warmin p tential)

when es a in from the RE RIGER TING SYS EM

HAZA DS d e to the states of pres ure an temp rature in RE RIGER TING SYS EMS are

es ential y d e to the simultane u presen e of the lq id an va our phases Furthermore,

the state of the refrigerant an the stres es that it exerts on the variou comp nents do not

de en solely on the proces es an fun tion in ide the plant, but also on external f actors

The fol owin H ZA DS are worth of note:

a) f rom the direct ef f ect of extreme temp rature, for example:

– britlenes of materials at low temp ratures;

– f re zin of en losed l q id (water, brine or simi ar);

– thermal stres es;

– c an es of volume d e to temp rature c an es;

– injuriou ef fects to p rson cau ed by low temp ratures;

– tou ha le hot s rfaces

b) f rom ex es ive pres ure d e to, f or example:

– in re se in the pres ure of con en ation, cau ed by inadeq ate co l n or the p rtial

pres ure of non con en a le gases or an ac umulation of oi or l q id refrigerant;

– in re se in the pres ure of saturated va our d e to ex es ive external he tin , for

example of a l q id co ler, or when defrostin an air co ler or hig ambient

temp rature when the plant is at a stan sti ;

– exp n ion of l q id refrigerant in a closed sp ce without the presen e of va our,

cau ed by a rise in external temp rature;

temp rature at dis harge, lq id slu gin (refrigerant get in into the compres or's oi

reservoir red cin the lubrication or cre tin a f roth , in ompres ible, mixture whic could

then get s c ed into the piston), er one u o eration an red ction in mec anical stren th

cau ed by cor osion, erosion, thermal stres , lq id hammer or vibration
