Hazards or accidental injuries according to the International Labor Organization (1) include sprains and strains due to slips and falls while carrying heavy loads or working in slippery areas soiled with excrement or while using related equipment and vehicles , burns due to exposure to hot surfaces ( (e.g. incubators, debeaking tools). Physical risks include exposure to high levels of noise which may cause noise-induced hearing problems, exposure to various hot or cold temperatures due to long-term outdoor work and resulting in heat exhaustion, heat- or sun-induced dermatosis (1). Sources of noise in poultry production outside the barn they can be fans, feeders, agricultural equipment which can result in noise levels well above 90 dB. Birds are the main source of noise inside barns. It has been reported that sound levels inside the chicken coop can vary between 50 dB e 90 dB during the day and when the roosters crow (2). Given that the maximum allowable exposure to continuous noise for 8 hours is 85 dB in all jurisdictions in Canada except Quebec (90 dB) (3), poultry workers exposed to noise levels above 85 dB are advised to wear hearing protection (4 ).Chemical risks involve exposure to organic dust (feathers, hair...... half of the paper......ten man-made.
