List and description of the relevant hazards with related estimation of frequency and duration of exposure

	Description	Percentage of birds exposed (or probability of a single bird being exposed to it) – worst‐case scenario	MAXIMUM duration of the exposure to the hazard – worst‐case scenario – (NB: direct exposure, not related to the persistence of the welfare consequences)
Fact/Operation/Process IN CONSCIOUS ANIMALS
Handling	Being caught by an operator by the legs and being held upside down	100%	00:00:05
Hanging and compression of the legs	Being suspended upside‐down by the legs and being conveyed and being subject to compression of the legs by metal bars	100%	00:01:00
Removal of air	Exposure to an environment with progressive depletion of air	100%	00:01:20
Potential gas expansion in body cavities/internal organs	Potential expansion of the gases contained in the intestine, the air sacs and the internal ear due to a reduction of the atmospheric pressure in the environment	100%	00:01:20
Acidic gas or gas mixture	Inhalation of an acidic gas or gas mixture	100%	00:00:30
Respiratory stimulant gas or gas mixture	Exposure to a gas or gas mixture that leads to increasing depth and rate of breathing	100%	00:00:30
Unintended electric shock	Being subject to a pre‐stunning electric shock in any part of the body	25%	00:00:01
Neck cutting	Cutting the neck while still conscious (severance of the tissues around the neck)	5%	00:00:01
Bleeding	Bleeding to death while recovering consciousness	5%	00:00:15
High stocking density	High stocking density reduces space allowance and increase the probability of collision between the neighbouring animals	100%	00:01:00
Tipping/Tilting	Sudden fall in groups onto a moving conveyor	100%	00:00:20
Noise	Being exposed to a sudden unexpected loud noise	100%	00:01:18
Decreasing air humidity	Exposure to an environment with progressive depletion of humidity	100%	00:01:20
