| Description | CPS is fabricated from PVC and special chemical barrier materials which will protect the wearer from harmful chemicals at incidents. Whenever CPS is used at incidents, appropriate type of Respiratory Protection Equipment (breathing apparatus or respirators) should be worn. |
| Function |
There are three types of CPS in use in the Service, namely Level A, Level B & Level C. Level A CPS are totally encapsulating vapour tight suits. Level A represents the greatest danger of respiratory, eye or skin damage from hazardous vapours, gases, particulates, sudden splash, immersion or contact with hazardous materials. It calls for total encapsulation in a vapour tight CPS with positive pressure Twin Cylinder Breathing Apparatus (TCBA) worn inside the CPS. Level A CPS provides the highest degree of protection to wearers and it shall be worn when responding to incidents where properties of encountered chemicals are highly toxic or unknown. Level B CPS are encapsulating suits. Level B situations call for the highest degree of respiratory protection but a lesser need for skin protection. It calls for positive pressure Self-contained Breathing Apparatus (SCBA) or Airliner Unit (ALU) with escape SCBA, plus hooded chemical resistant clothing. Level B CPS provides high degree of protection to wearers and it shall be worn when responding to incidents where properties of encountered chemicals are known and concentrations of which do not require a degree of protection as Level A. Level C CPS are splash suits. Level C situations call for a lower level of respiratory protection. Level C CPS is used when responding to incidents where the known chemicals are well below established exposure limits. Air purifying respirators should be worn with these suits. |
