4.6 Noise hazard Smokehouses can generate noise which might result in hearing damage and accidents caused by lack of speech communication and acoustic signals. 4.7 Hazards from non-compliance with ergonomic principles during construction Physiological hazards can result from:
excessive lifting, pushing and pulling; an unhealthy posture of body due loading and unloading as well as maintaining and cleaning of the smokehouses. SIST EN 15861:2012
EN 15861:2012 (E) 12 4.8 Hazards from non-compliance with hygiene principles Significant health hazards can arise from: biological issues such as pathogens and micro-organisms which can cause spoilage, poisons or pests; chemical issues such as cleaning and disinfecting agents as well as lubricants; foreign bodies from raw materials within the smokehouse and from other sources. From each of these hazards, risks of contamination of the foodstuff and/or injuries to the health of the consumer are possible. Microbiological hazards can lead to the spoilage of food-stuffs, food poisoning or to other sicknesses of the consumer. Chemical hazards may contaminate the food-stuff or leave residues behind in the food-stuff, which may be detrimental to health (e.g. acid burns or dangerous fumes). Foreign bodies can contaminate the foodstuff and cause physical damage (e.g. suffocation, cutting injuries). 4.9 Thermal hazards 4.9.1 Hazards from hot surfaces Hazards from hot surfaces include hazards from burns in the zones 1, 2, 3 and 7. 4.9.2 Hazards from hot steam Hazards from hot steam can result from escaping steam from the smokehouse when the door is opened and from scalding. 4.10 Being enclosed Hazards from being enclosed include hazards due to heat and suffocation. 4.11 Explosion hazards Explosive hazards can arise if smoke-gas-air-mixtures occur in an explosive concentration. 4.12 Hazards from chemical materials and agents Hazards from chemical materials and agents include risks of damage to health, especially irritation and/or chemical burn from contact with and/or inhaling of cleaning agents, liquid smoke, saw dust or smoke. 4.13 Hazards from slipping, tripping and falling Hazards from slipping, tripping and falling are due to the omission of non-slip floor surfaces and accesses.
