In the process of construction and commissioning of large livestock complexes and industrial-type farms, difficulties arise associated with the organization of safety measures and industrial sanitation directly at the facilities and with the protection of the environment from pollution by animal waste.
We studied the working conditions of workers serving buried premises and containers for the collection and temporary storage of animal waste at pig feeding enterprises. When collecting and storing manure, as a result of active biological processes, it releases chemicals, many of which can adversely affect the human body. These are ammonia, hydrogen sulphide, mercaptans, etc. In the process of monitoring pumping installations and the level of liquid manure in tanks and slurry tanks, routine repair of equipment, during cleaning of precise channels and routine repairs in sewer wells in violation of safety rules, inhalation of air containing elevated concentration of toxic substances can lead to the development of acute poisoning.
In order to improve working conditions and prevent accidents at sites, we have proposed specific measures, including the following hygienic recommendations ...(look at the text of article)
Besides THIS, it is recommended:
all those who come to work in buried rooms and containers must be subject to a medical examination, and in the future - to periodic medical examinations. Do not allow persons suffering from diseases of the cardiovascular system, broncho-pulmonary apparatus and the central nervous system (epilepsy, etc.) to work in buried rooms and containers;
before starting work, instruct the team (at least 3 people) in detail on the rules for working in buried rooms and familiarize it with the properties of harmful gases;
allow work in buried rooms and containers only in personal protective equipment;
to provide workplaces with visual agitation about safety measures when working in slurry collectors (memos, posters);
train working and buried containers and premises in the first and first aid measures, including artificial ventilation of the lungs as a mandatory element;
ns allow adolescents under 18 years of age, women with babies and pregnant women to work in slurry tanks and wells;
provide workplaces in buried rooms and containers with a first aid kit with a list of medicines and a short guide to their use;
to require, when working in sewer wells in slurry tanks, strict adherence to safety measures provided for by the current instructions and regulations.
Plant managers and safety engineers must deeply analyze the causes of every accident that occurs in buried areas and take immediate measures to prevent them.
