Some hazards are easily recognized, for example an employee climbing up a 20-ft ladder while holding tools in both hands is an obvious fall hazard. While some safety hazards are immediately recognizable, others require training to spot and avoid. One such hazard is hydrogen sulfide (H2S). Training is a key method to avoid the “ostrich zone.” You do not want to bury your head when facing this hazard.  \nAnalyzing H2S  \nH2S is a clear gas that is dangerous to human health/life, extremely flammable, corrosive and sometimes has a detectable odor of rotten eggs. It can be produced in bogs, swamps, volcanoes and hot springs (EPA, 1993). It can also be produced by industrial activities (e.g., oil and gas, natural gas pipeline transmission, refineries, sewage treatment plants, manholes, manure pits) . Whether its source is natural or industrial, H2S is the result of bacterial decomposition of organic material.  \nThe Hazard  \nA very low-level H2S exposure can result in serious illness or death. The NIOSH value for immediately dangerous to life or health (IDLH) is 100 ppm, and 1% of H2S = 10,000 ppm.  \nIn addition, this hazard occurs where one might not expect. For example, a 25-year-old waste hauling service worker died in an underground manure waste pit. The access opening was fitted with a removable stainless steel cover. There was no ventilation or gas monitor in use [OSHA(b)] . NIOSH (2012) lists multiple instances of H2S-related fatalities occurring on farms and sanitation facilities involving enclosed/confined spaces harboring this deadly gas. In none of these cases was a gas monitor used to indicate the presence of this gas.  \nWhy So Deadly?  \nH2S is an inhalation, flammable, explosive and contact hazard. Inhalation symptoms at low-level exposures (20 ppm) include headache, dizziness, sleep disturbances, upset stomach and changes in appetite. Symptoms include altered breathing and drowsiness after 15 to 30 minutes at this level. Death may occur after 48 hours and exposures rang-  \ning to 500 to 700 ppm will likely result in staggering, collapse and death after 30 to 60 minutes. A level of 1,000 to 2,000 ppm would result in nearly instant death [OSHA(c)] .  \nH2S is also corrosive and will act on skin and eyes. Exposure levels of 50 to 100 ppm will cause eye irritation and marked conjunctivitis, and respiratory tract irritation after an hour at 200 to 300 ppm [OSHA(c)] . Acute exposure can cause painful conjunctivitis, sensitivity to light and corneal abrasions (CCOHS, 2013) . H2S is classified as a chemical asphyxiate similar to carbon monoxide and cyanide gasses. It inhibits cellular respiration uptake of oxygen causing biochemical suffocation (Kalusche) .  \nAcute exposure affects the nervous and pulmonary systems, olfactory nerves, lungs, brain, respiratory control center and eyes. Symptoms include nausea, burning sensation in the eyes, coughing, dizziness, difficulty breathing, fluid accumulation in the lungs, headache, vomiting, staggering and excitability. The symptoms displayed depend on exposure level and length, and a worker’s physical condition. Once any of these symptoms is exhibited, a dangerous exposure has already occurred.  \nProtecting Against H2S  \nTraining is key to recognizing this hazard and protecting against it. Training levels are dependent on the action expected of the employee/trainee. For example, if a person’s work will rarely result in H2S exposure and if the employee is expected to immediately evacuate a site upon H2S detection, awareness training and training on use and care of a gas monitor is likely adequate.  \nIf the employee works in a setting where H2S is likely, then training must address more advanced topics, including special evacuation criteria; use of respiratory PPE and gas monitor use/care; first aid; expectations of employees in an ","cbCaiixTGVaROo4l","https://ap.wps.com/l/cbCaiixTGVaROo4l","pdf",800822,"English","# Hazard recognition and the “ostrich zone”\n## Analyzing H2S\n## The hazard and exposure consequences\n## Why so deadly\n# Protecting against H2S\n## Training and contingency planning\n## Equipment, confined spaces, and safe work practices\n# Detection and limitations of smell","[{\"question\":\"What is the “ostrich zone” in the context of hydrogen sulfide safety?\",\"answer\":\"It refers to the tendency to ignore or fail to recognize hazards.
