Ready made garments factory in Bangladesh are severely vulnerable to electric fire. Recently the world class brands like WallMart , C&A, H&M, GAP persuade and invested to ensure minimum safety.
At the previous article (Part-1) I had mentioned some most critical non-conformities. In this post I will describe some others not critical but highly hazardous(Non-corfomities are categorized in three namely – [alvaa]Critical, highly hazardous, hazardous ). This article is the continuation from the previous one. All these possible non-conformities are from some codes or gadget which are, most importantly Bangladesh National Building Code (BNBC), Bangladesh Electrical Rules-1937 (BER), National Fire Protection Association-70 (NFPA-70) and British Standards (BS).
The behind story of these articles is recent awareness and investment of multinational ready made garments giant retailers like WallMart, H&M and others to inspect & asses the factory safety standards for electrical and fire safety. Bureau Veritas Bangladesh on behalf of international retailers is inspecting and standardizing the factories in three categories in a mission to motivate or bound the factories to maintain standard for Electricity and Fire
The complete assessment is categorized mostly into 3 (A,B,C) parts where category-A’ is for ‘immediate corrections needed’ and category-C is for ‘observation and monitoring needed’. The factory is given 30 days period for the corrections of category-A, while 180 days for the category-C.
Here comes the most important non-conformities (NC). This can be divided into parts. 1. Drawings, 2.Planned schedule in registered log book with mentioning due dates, 3. Planned schedule in notice board with mentioning due dates, 4. Instruction boards, 5. Marking of cable, 6. Panel size, 7. marking of cable and circuits
[adsfl]Each and every panels should have its own Single line diagram in the outside of the panel. This will be easy if the updated single line diagram of the whole factory is available. This is mentioned earlier at point number 1. What to do is-Manage the SLD, then print the individual panel SLD from the whole AS BUILT (updated) SLD and fix it in the outside of the panel (Panel door). It should be noted that the SLD should have included everything like CB type and rating, Cable sizes, connected load.
Planned schedule and audit plan in registered log book
Circuit current should be measured at least once in every year, better in 6 months. This should be mentioned in the registered book with next due date. This is called planned schedule. You need to know your factory plan for next one year.
Insulation test or Meggar Test of the insulation of the cable should be carried out once in every 6 months. This should be mentioned in the registered book with next due date. Earth resistance test of the earthing cable from the earth pit or boring should be carried out once in every 6 months. This must not be more than 1 ohm. If it is more that 1 ohm, it needs maintenance work like pouring salt water into the boring. This should be mentioned in the registered book with next due date. The results must be kept.
If the factory audit is done in May 2013, next audit must be carried out within 2 years by any third party. So this will be due on May 2015. It must be done by any 3rd party. A notice must be signed by the authority that the electrical assessment of XYZ factory has been done by ABC company on May 2013. The due date for next assessment is May 2015. This notice should be paste on the Generator control room.
Instruction boards outside of panel
Every panel must have 2 instructions. Firstly, the instructions of restoration of person suffering from electric shock. That means, what to do if a person got electrical shock. Secondly, What to do for Artificial respiration. That means blowing into the mouth of the suffering person and pump at the chest. The steps procedure should be hanged on the panel. The instruction page must have colour pictures with Bengali and English translation of the procedure. If there is not enough space at the panel door then fix that instruction beside the panel.
Marking of circuits and cable inside of panel
Every circuit should have at least one earth conductor. And if neutral needed then it must be inside the panel. So one panel must have earth bus-bar and neutral bus-bar. Number of earth wire should be same with the number of circuits in the panel. The earth and neutral wires should be marked or tagged mentioning the circuit number or Circuit Breaker number so that one can understand the individual earth or neutral cable for which circuit it is connected. Find cable marker in markets.
