1.0 OBJECTIVE
To define the standard entry procedure for personnel into the manufacturing corridor of the oral solid dosage (OSD) area to prevent contamination, mix-ups and to maintain GMP.
2.0 SCOPE
This procedure is applicable to all personnel (Production, QA, Maintenance, Housekeeping, Visitors) entering the OSD manufacturing corridor and its associated rooms.
3.0 RESPONSIBILITY
- All Personnel – To follow this entry procedure strictly.
- Production / QA – To ensure compliance and perform routine checks.
- HR / Training – To ensure all concerned staff are trained on this SOP.
4.0 GENERAL REQUIREMENTS
4.1 Health & Hygiene
- Do not enter if you have:
- Open wounds, oozing skin lesions, severe respiratory infection, or diarrhoea.
- Report sickness to supervisor / HR before entering.
4.2 Personal Items (Before Entry)
- No jewellery, watches, bangles, loose chains.
- No cosmetics, strong perfumes, hair oil that may shed/emit vapours.
- No eatables, water bottles, mobile phones, pens with loose caps, etc. inside manufacturing corridor (unless specifically allowed and controlled).
5.0 ENTRY FLOW – MANUFACTURING CORRIDOR (TYPICAL TWO-CHANGE SYSTEM)
Adjust “Room-1, Room-2” names as per your site layout.
5.1 Entry to Primary Change Room (Street to Plant)
- Enter Change Room–1 (Primary) from external corridor.
- Verify:
- Status board / door label – “CHANGE ROOM – CLEAN / IN USE”.
- Housekeeping and waste bins are clean and not overflowing.
- Remove:
- Street footwear, place in designated rack.
- Personal jackets/outerwear, caps, etc.
- Wear:
- Plant slippers / shoes provided in the change room (clearly identified by colour/ID).
- Hairnet / head cap to fully cover hair.
- Beard cover (if applicable).
You are now in “plant attire” but not yet ready for manufacturing corridor.
5.2 Entry to Secondary Change Room (Plant to Manufacturing Corridor)
- Enter Change Room–2 (Secondary / Airlock) from plant side.
- Ensure differential pressure and temperature are within limits (display / BMS / magnehelic gauge):
- Temp: NMT ___ °C (e.g. 27 °C)
- RH: NMT ___ % (e.g. 55%)
- DP as per layout (corridor > change room > external).
- Remove plant slippers and wear corridor-designated footwear if system demands separate shoes (ex: blue = corridor, green = core area).
- Perform hand hygiene:
- Wash hands with liquid soap and potable water (if hand wash station present).
- Dry hands with disposable tissue, not cloth towel.
- Apply hand disinfectant (IPA-based / site approved).
- Wear corridor gowning as per your site (typical OSD):
- Clean inner protective clothing, such as:
- Trouser & shirt / coverall
- Over-gown / lab coat (if used)
- Head cover & beard cover (if not already adequate).
- Disposable mask or reusable mask as per SOP.
- Powder-free gloves (if required at corridor level; mandatory for entry into rooms where product is exposed).
- Clean inner protective clothing, such as:
- Check gown:
- No open buttons/zip.
- Gown not torn, stained or excessively creased.
- Step on foot bath / sticky mat / shoe sole cleaner (as applicable) at exit of change room.
- Enter the manufacturing corridor only through the designated personnel door.
- Do not hold doors open with wedges or bins.
- Ensure door is properly closed behind you (airlock principle).
6.0 RULES INSIDE MANUFACTURING CORRIDOR
Once inside the corridor:
6.1 Movement & Behaviour
- Walk calmly, do not run or push trolleys aggressively.
- Avoid leaning on walls, doors, equipment windows.
- Do not sit on the floor, pallets, or steps in the corridor.
6.2 Material & Document Handling
- Use designated material doors / pass boxes for materials – never carry materials through personnel airlocks if SOP prohibits.
- Carry BMR / documents in clean document folders; do not place directly on floor.
6.3 Gown Integrity
- Keep gown fully closed at all times.
- If gown gets visibly dirty, torn, or wet, exit via proper route and replace gown before re-entry.
6.4 Food / Drink / Smoking
- No food, chewing gum, tobacco, pan, etc.
- Smoking strictly prohibited anywhere inside production block.
7.0 TEMPORARY EXIT & RE-ENTRY DURING SHIFT
(Example: washroom break, cafeteria, meeting)
7.1 Exit Procedure
- Exit manufacturing corridor via reverse gowning sequence defined in plant SOP (usually back through secondary change, then primary).
- Remove outer gown and corridor footwear in the correct order and store in designated racks/lockers if re-use is allowed for the same shift; else send for washing/disposal.
7.2 Re-Entry
- Re-enter following full entry procedure again:
- Primary change → Secondary change (hand wash, mask, cap, gown, footwear) → Corridor.
- Do not short-cut steps because it’s a “quick” entry.
Rule of thumb: Each time you cross from non-manufacturing side to manufacturing corridor, perform the full entry sequence.
8.0 EXIT AT END OF SHIFT
- Exit manufacturing corridor through designated personnel exit.
- Remove gloves and discard in bio / general waste as per segregation SOP.
- Remove gown in change room, turn inside out (if reusable), and place in soiled linen bin.
- Remove mask, cap, beard cover and discard as per waste SOP.
- Remove corridor footwear and place on rack; change to plant / personal footwear in primary change room.
- Wash hands before leaving the block.
