There are six levels of language proficiency (A1, A2, B1, B2, C1, C2) according to the CEFR scale. They are grouped into three broader levels: A1-A2 (Basic User), B1-B2 (Independent User), and C1-C2 (Proficient User).
Here we explain what each observation code means, with EICR observation code examples, so you can better understand your EICR. Fixed wire testing observation codes: C1 C2 C3 Observation Code C1. The most severe observation code, C1 means danger is present and there is an immediate threat to property or life.

An example of a C1 observation (it's dangerous now!) would be the cover of a consumer unit missing hence exposing live parts. Any exposed live parts such as an open consumer unit busbar or an exposed live cable end would be classed as a code 1, as it is dangerous (right now) at the time of the inspection. C2 = Potentially dangerous

Deficiency in C1, C2, C3, MBL, MBL-associated serine protease 2 (MASP-2), factor H, factor I, or complement receptor 2 (CR2): Susceptibility to recurrent bacterial infections Deficiency of C5, C9, factor B, factor D, or properdin: Susceptibility to neisserial infections Meningococcal Diseases Meningococci ( Neisseria meningitidis ) are gram
Like a C1 code, any issues categorised as C2 will mean the EICR is unsatisfactory until action is taken. EICR C3 meaning. Moving onto EICR C3, this code means that improvements are recommended for your electrical installation. An example could be wiring that doesn't meet the latest regulations, but that isn't a risk in itself.
A Code 1 (C1) observation means ' Danger present. Risk of injury. Immediate remedial action required.' A C1 represents an immediate threat to the safety of your employees, customers or guests and should be rectified or made safe as soon as possible.
C1 - Very low. Heated buildings with clean atmosphere. In this environment you can use untreated steel or painted steel. The C1 class includes materials that are not exposed to corrosion in normal atmospheric air. This can be: Schools; Shops; Hotels; C2 - Low. Atmosphere with little or no degree of pollution. Country atmosphere where tUP0J.
