Hazards in High Temperature Work Environment

Hazards in elevated Temperature Work surroundingsProduction environment meteorological conditions affected plant construction, ventilation equipment, cultivate and invest off conditions, etc., while at gritty temperatures or the presence of soaring give vent humidity or inflame beam and other unfavourable weather conditions, end product labor, it may become a high-temperature operation.High temperature sortingHigh temperature, disturb ray of light jobs as between metallurgy, casting, forging, take fire discussion furnace workshop, boiler, etc. These oeuvres high temperatures, high thermal radiation intensity, is dry and furious environment.Hot, humid jobs such as dyeing, reeling, paper, wet deep mine operations, in general due to the large amount of urine vapor generated during return or production process requirements workshop to maintain a high sexual intercourse humidity due.Outdoor spend jobs as summer farm labor, construction, tape transport and other o ut-of-door jobs, mainly due to direct solar radiation and horninessing the ground and surrounding objects form a secondary consequence of the additional foment affected.What are the wellness make of high temperature?High temperatures goat lead to acute affectionateness-induced illness (such as barbed hot, thorny heat and heat scene) and chronic thermally induced disease (chronic heat failure, hypertension, myocardial damage, digestive disorders, skin diseases, tropical lethargy, kidney stones, hot water confrontation failure, etc.).E wellness Education and progression missionaries taught forum 03 occupational hazards and wellness personal effects heat nip 2010715162605.jpg occupational heat crack in high temperature operating environment, due to thermal equilibrium and (or) water-salt metabolism disorders cause by central nervous system and (or) cardiovascular disorders as the main locution of acute illness.What are the clinical manifestations of occupational heat strok e, heat stroke after how this process?Heatstroke melodic phrase After some era working(a)s workplace temperature, dizziness, headache, thirst, sweating, general fatigue, heart palpitations, inability to concentrate, incoordination and other symptoms, the system temperature normal or slightly elevated.Principles Temporarily out of high-temperature field, and be closely observed.Mild heat stroke In addition to the aggravation of the symptoms of heat stroke, the emergence of facial flushing, sweating, rapid pulse, such as performance, torso temperature rises above 38.5 .Principles rapidly from the high-temperature field, to the shade to comfort give a refreshing throw salt and symptomatic treatment.Severe heat stroke cease be divided into heatstroke, heat cramps and heat debilitation III, also stinker have the appearance _or_ semblance mixed.E wellness Education and Promotion missionaries taught forum 03 occupational hazards and health effects heat stroke 5604331_993159. jpg heatstroke (including sunstroke), also known as heat stroke, high fever, the body heat in hot environments stop thermoregulatory mechanism disorders caused high mortality rate (20 to 40%). Which is characterized by choppy onset of high temperature environment, the temperature up to 40 , early disease sweating, followed by no sweat, hot and dry skin may be associated with several(predicate) levels of consciousness disorders.Heat cramps due to excessive sweating, body sodium, potassium acquittance caused by excessive. Mainly for the obvious muscle spasm, accompanied by abbreviation pain. Occur in many activities, such as abdominal muscles and limbs, particularly for the gastrocnemius. Often has symmetry. Some generation seizures, some cadences ease. Patients with clear consciousness, body temperature normal.Heat exhaustion is a high temperature, high humidity environment, extend skin squanderer flow is non accompanied by a corresponding increase in splanchnic vasoconstric tion or blood volume, the body washbowl not compensate temporary brain ischemia induced syncope. The main clinical manifestations of dizziness, headache, sweating, thirst, nausea, vomiting, and then clammy skin, blood pressure, heart rhythm disorders, mild dehydration, the body temperature slightly higher or normal. Usually a short cash in ones chips to clear, generally do not cause circulatory failure.E Health Education and Promotion missionaries taught forum 03 occupational hazards and health effects heat stroke QQ picture 20130701150544.jpg principles rapidly be physical chill and (or) drugs cooling correct water and electrolyte imbalance symptomatic treatment.Stroke patients with incidentally treatment, and tummy be quickly restored without having transferred from the original work.The importance of missionary trainingE Health Education and Promotion missionaries taught forum 03 occupational hazards and health effects heat stroke 201076192404.jpg if workers in high temperat ure environment, the employer is necessary to workplace hazards temperatures timely assessment of the situation, and to develop plan to prevent heat stroke. In addition, the employer shall suffer workers and their exposure to high temperature hazard awareness training competent enough, the kernel should include the following components awareness (1) high temperature hazards, (2) occupational heat stroke prevention, (3) how to recognize heat stroke symptoms, (4) when their stroke symptoms appear or colleagues how to do. think If a worker or colleague can leave a hot environment that is in the early stages of heat stroke occurs, you can effectively avoid aggravating the problem.What measures should be taken to control workplace hazards temperature?E Health Education and Promotion missionaries taught forum 03 occupational hazards and health effects heat stroke 1315212318.jpg technical measures1 rational design of production processes Improved production equipment and method of operat ion is the fundamental measures to improve the working conditions of high temperature operation. Such as steel casting, rolling, casting, enamel and other production automation, allows workers away from heat, while reducing labor intensity. Heat source transcription should meet the following requirements try disposed outside the shop When utilise hot-based natural ventilation, as arranged in the skylight below When victimization drafts based natural ventilation, as arranged in the summer the preponderant wind direction leeward side take on heat insulation measures so easy to use cooling measures work place, you can set partition (plate) between the heat source, so that hot air rises along the wall, through the skylight discharge, in order to avoid mete out throughout the workshop hot finished and semi-finished out of the workshop should be downwind side or stacked.2 Insulation Insulation is an of the essence(predicate) measure to prevent heat radiation, can use water or th ermal conductivity of insulation materials, including large specific heat of water, can effectively absorb radiant heat.E Health Education and Promotion missionaries taught forum 03 occupational hazards and health effects heat stroke 7576382.jpg3 ventilation and cooling through doors and windows, natural ventilation slits have some effect, however the high temperature in this way alone workshop often can not meet the cooling needs, this time can be used to achieve mechanical ventilation cooling purposes.4 temperature and humidity legislation system The air conditioning system can effectively ignore the temperature in the workplace, for the presence of open water tanks, steam valves and other heat sources, can be used dehumidifier system reduces the temperature of the air in the workplace.Health measures1 hot work should be supplemented with the sweat of workers equal amount of water and salt. The salt content of the beverage 0.15% and 0.2% is appropriate. Drinking a few times app ropriate manner. Labor in a hot environment, the energy expenditure increases, so should be appropriate to add the total dietary calories and vitamins.E. Health Education and Promotion missionaries taught forum 03 occupational hazards and health effects heat stroke 414007_066080.jpg2 temperature worker overalls, should heat, thermal conductivity and permeability of level-headed fabric. Prevent radiant heat, available white overalls made of canvas or aluminum foil. Special high-temperature operation of workers, such as thermal facing repair, cleaning and other types of ladle to prevent intense heat radiation effect, are required to wear masks and wearing thermal insulation, fire-retardant, ventilation heat protective clothing, such as spraying metals (copper, silver) insulation masks, aluminum insulated clothing.3 workers exposed to high temperatures should be pre-employment physical examination and the summer before, where in that respect is uncontrolled hypertension, chronic nep hritis, uncontrolled hyperthyroidism, uncontrolled diabetes, the body above the gelt area 20% (injury standard eight) as well as those who break to the high-temperature operation of epilepsy disease contraindications, should not engage in high-temperature operation. In addition, arrangements must(prenominal) not engage in female workers during pregnancy third level, tail level jobs temperature specified in the job grading standards.E Health Education and Promotion missionaries taught forum 03 occupational hazards and health effects heat stroke 4_110803104730_1.jpg managementAccording to regional climate characteristics, appropriate adjustments to labor and rest in summer high temperature regime. Pergola lounge or seat should be set up away from heat sources as possible, in that location must be adequate cooling facilities and beverages. Large factories can set up special air-conditioning system with the rest of the workers apartment, to ensure workers exposed to high temperatu res during the summer months there is sufficient sleepy eyes and rest. Outdoor summer jobs as well as jobs in workplace temperature can not be controlled below 33 , the employer to the employee shall be paid a periodical allowance temperature.Organizational measures(A) The maximum daily temperatures reach above 39 , the mean solar day should stop outdoor open-air work(B) the daily maximum temperature reached little than 37 to 39 (excluding 39 ), the day outdoors outdoor working hours shall not more than six hours, 1200 to 1600 outdoors outdoor work should be suspended(C) the daily maximum temperature reaches above 35 to below 37 (excluding 37 ), the employer shall take the holiday shift, etc., to shorten the time of continuous operation, and shall arrange outdoor open-air job workers to work overtime.(D) shall not cause pregnant women and juvenile workers in the workplace more than 35 hot weather and outdoor work in temperatures above 33 .Emergency Health CheckFor the hot se ason there have heatstroke aura job workers, or exposure to high temperatures due to the accident or occupational exposure may lead to heat stroke populations (including corporation accident rescue personnel), when asked whether headache, dizziness, chest tightness, palpitations, sweating , fever, little or no urine and other symptoms, and observe the condition of consciousness. Physical examination should focalisation on checking temperature, blood pressure, pulse and nervous system, and carry out blood, urine, blood serum electrolytes and renal function and other laboratory tests.Diagnosis apply occupational heat strokeWhen the diagnosis of occupational institution for occupational heat stroke diagnostic materials need to be prepared include(A) trial impression of render of health damage, such as occupational health inspection results(B) separate to prove labor relations, such as labor contracts, work permits, the employer proofID card copy (three) require diagnosis workers(D ) Other evidence as occupational history, history of exposure to high temperatures and weather conditions at work, workplace temperature detection and evaluation information.
