Odor Control >> How To Get Rid Of Dead Animal Odor

Sulfide is a colorless, flammable, extremely hazardous gas with a "rotten egg" smell. Some common names for the gas include sewer gas, stink damp,swamp gas and manure gas. It occurs naturally in crude petroleum, natural gas,and hot springs. In addition, hydrogen sulfide is produced by bacterial breakdown of organic materials and How To Get Rid Of Dead Animal Odor human and animal wastes (e.g., sewage).

Industrial activities that can produce the gas include petroleum/natural gasdrilling and refining, wastewater treatment, coke ovens, tanneries, and kraftpaper mills. Hydrogen sulfide can also exist as a liquid compressed gas. Hydrogen sulfide is heavier than air and maytravel along the ground. It collects in low-lyingand enclosed, poorly-ventilated areas such asbasements, manholes, sewer lines, How To Get Rid Of Dead Animal Odor underground telephone vaults and manure pits.

For work within confined spaces, use appropriate procedures for identifying hazards,monitoring and entering confined spaces.The primary route of exposure is inhalation How To Get Rid Of Dead Animal Odor and the gas is rapidly absorbed by the lungs.Absorption through the skin is minimal. People can smell the "rotten egg" odor ofhydrogen sulfide at low concentrations in air.

However, with continuous low-level exposure, or at high concentrations, a personloses his/her ability to smell the gas eventhough it is still present (olfactory fatigue).This can happen very rapidly and at highconcentrations, the ability to smell the gascan be lost instantaneously. Therefore, How To Get Rid Of Dead Animal Odor DO NOT rely on your sense of smell to indicatethe continuing presence of hydrogen sulfideor to warn of hazardous concentrations.

In addition, hydrogen sulfide is a highly flammable gas and gas/air mixtures can be explosive. It may travel to sources of ignition andflash back. If ignited, the gas burns to produce toxic vapors and How To Get Rid Of Dead Animal Odor gases, such as sulfurdioxide. Contact with liquid hydrogen sulfide causesfrostbite. If clothing becomes wet with theliquid, avoid ignition sources, remove theclothing and isolate it in a safe area to allowthe liquid to evaporate.

Health effects of H2S exposureHydrogen sulfide is both an irritant and achemical asphyxiant with effects on bothoxygen utilization and How To Get Rid Of Dead Animal Odor the central nervoussystem. Its health effects can vary dependingon the level and duration of exposure. Repeated exposure can result in health effectsoccurring at levels that were previously tolerated without any effect.

Low concentrations irritate the eyes, nose,throat and respiratory system (e.g., burning/tearing of eyes, cough, shortness of breath).Asthmatics may experience breathing difficulties. The effects can be delayed for severalhours, or sometimes several days, How To Get Rid Of Dead Animal Odor whenworking in low-level concentrations. Repeatedor prolonged exposures may cause eyeinflammation, headache, fatigue, irritability,insomnia, digestive disturbances and weightloss.

Moderate concentrations can cause moresevere eye and respiratory irritation (includingcoughing, difficulty breathing, accumulationof fluid in the lungs), headache, dizziness,nausea, vomiting, staggering and excitability. High concentrations can cause shock, convulsions, inability to breathe, How To Get Rid Of Dead Animal Odor extremely rapidunconsciousness, coma and death. 

Effects can occur within a few breaths, and possiblya single breath.Protection against H2S exposureBefore entering areas where hydrogen sulfide may be present:1. Air must be tested for the presence and How To Get Rid Of Dead Animal Odor concentration of hydrogen sulfide by aqualified person using air monitoringequipment, such as hydrogen sulfidedetector tubes or a multi-gas meter thatdetects the gas.

Testing should also determine if fire/explosion precautions are necessary.2. If the gas is present, How To Get Rid Of Dead Animal Odor the space/area mustbe ventilated continually to remove thegas.3. If the gas cannot be removed, the personentering the space/area must use appropriate respiratory protection and anyother necessary personal protectiveequipment, rescue and communication equipment.

OSHA's Confined Spaces standard contains specific requirements for identifying, How To Get Rid Of Dead Animal Odor monitoring and entering confined spaces. ring dangerous H2S atmospheresA level of H2S gas at or above 100 ppm isImmediately Dangerous to Life and Health(IDLH). 

Entry into IDLH atmospheres can onlybe made using: 1) a full facepiece pressuredemand self-contained breathing apparatus(SCBA) with a minimum service life of thirtyminutes, or 2) a combination How To Get Rid Of Dead Animal Odor full facepiecepressure demand supplied-air respirator withan auxiliary self-contained air supply.

If H2S levels are below 100 ppm, an air-purifying respirator may be used, assuming thefilter cartridge/canister is appropriate forhydrogen sulfide. A full facepiece respiratorwill prevent eye irritation.If air concentrations are elevated, How To Get Rid Of Dead Animal Odor eye irritation may become a serious issue. If a halfmask respirator is used, tight fitting gogglesmust also be used.

Workers in areas containing hydrogen sulfidemust be monitored for signs of overexposure.NEVER attempt a rescue in an area that maycontain hydrogen sulfide without using appropriate respiratory protection and How To Get Rid Of Dead Animal Odor without being trained to perform such a rescue. 

The trend towards larger and larger animal feeding operations, How To Get Rid Of Dead Animal Odor coupled with the influx of nonagricultural people into rural areas, has brought the issue of livestock odors to the forefront, in addition to concerns about water quality and the environment. Although water quality can be directly measured, odor strength and offensiveness can vary through personal perceptions. 

Perceptions are influenced by personal preference, opinions, experiences and variability in individual olfactory systems.Total elimination of odor from animal feeding operations probably never will be accomplished. However, How To Get Rid Of Dead Animal Odor management practices and technology are becoming available that are capable of reducing odor. 

Economic issues control the implementation of new odor technologies. The livestock industry is very competitive, with low profit margins. However, How To Get Rid Of Dead Animal Odor most producers agree that continued productivity, profitability, and sustainability of livestock production depends in part upon cost-effective technologies and management practices to mitigate odor. 

The following is a quick overview of some available practices and technologies. Most odor technologies work best in very specific situations, and How To Get Rid Of Dead Animal Odor should be thoroughly researched before being implemented. Odors in Buildings Odors associated with livestock buildings are often overlooked for the more obvious odor source -- the waste storage structure.

Cleanliness goes a long way to prevent odor from buildings.Keep floors as clean and dry as possible to avoid anaerobic decomposition of organic material. Avoid manure buildup, How To Get Rid Of Dead Animal Odor thereby decreasing odor sources. Provide adequate ventilation to prevent buildup of dust, gases, moisture, and heat that may intensify odor.

Make sure building interior surfaces are as smooth as possible to facilitate cleaning and reduce area for dust and debris to accumulate.Modify feed delivery systems to release as little dust as possible. Odorants readily attach to airborne feed particles How To Get Rid Of Dead Animal Odor and dust, which can be easily released to outside air.

Clean exhaust fans and How To Get Rid Of Dead Animal Odor shutters regularly of dust and debris to maximize warm season ventilation. Recharge, flush or scrape underfloor manure storage areas as frequently as possible.Small changes that may have a positive effect include:Cover recycle flush tanks. Extend recharge pipes and fill-water lines to the bottom of the pit and fit them with anti-siphon vents in order to reduce agitation of liquids.

Cover outside collection and junction boxes, sump tanks and storage basins, if possible.Waste Storage Structures:Lagoons or holding ponds that are designed and managed properly usually have low odor potential. However, How To Get Rid Of Dead Animal Odor if an anaerobic lagoon is undersized or organically overloaded, it may be a significant odor source.

Make sure lagoons are large enough to consistently treat and store manure. Fill new or emptied lagoons with four feet of water prior to the introduction of manure so waste solids will be submerged. This gives the different bacterial populations enough room to work and reduces the amount of complex How To Get Rid Of Dead Animal Odor and odorous compounds that will be released from the lagoon.

If possible, start loading new lagoons during the warmer summer months so that the bacteria needed for proper lagoon function may become established. Refrain from using harsh anti-microbial feed products, How To Get Rid Of Dead Animal Odor like copper sulfate, that may disrupt the microbial population of the lagoon. Land Application: The application of liquid manure onto cropland maybe a significant source of odors and nuisance complaints from surrounding neighbors. 

The following procedures may help alleviate those concerns.Adjust sprayers and spreaders so the waste is applied at low pressures. High pressures can aerosolize the waste and allow for more air contact.Apply wastes as close to the ground as possible. The higher the effluent is applied, How To Get Rid Of Dead Animal Odor the more air can mix with it and cause odors to be carried off the application site.

Apply manure during times when the air is warming and rising from the ground. This would normally be between the hours of 8 AM and 3 PM. Also, take into account prevailing winds, How To Get Rid Of Dead Animal Odor so odors won't be carried towards homes or businesses. 

Avoid application on hot humid days (where odors will stay close to the ground) and on weekends or holidays. Incorporation of the manure into the soil is a very effective technique of reducing odors. As soon as possible, How To Get Rid Of Dead Animal Odor incorporate manure if the soil type and costs aren't prohibitive.Establish setback distances from neighbors.
