Defeathering must be done immediately after bleeding ensuring that -
| a) | feathers may not be dropped onto the floor but must be put into containers, especially for this purpose, or into a chute leading to a feather holding room; |
| b) | personnel wear dust masks; |
| c) | a ventilation system or extractor fan providing a positive airflow from clean to dirty, must be operational during defeathering and must prove effective in preventing feather dust from moving into the dressing area and |
| d) | the hatch between the defeathering area and the dressing area must be kept closed except when carcasses are moved through to the dressing area. |
