1, tightly sealed to prevent leakage, the workplace to establish an independent local exhaust and comprehensive ventilation, away from fire, heat sources.
2. Smoking is strictly prohibited in the workplace.
3, hydrogen sulfide operating environment air hydrogen sulfide concentration should be measured regularly and set up hydrogen sulfide leakage detection alarm, the use of explosion-proof ventilation system and equipment, equipped with more than two sets of heavy-duty protective clothing. Wear chemical safety glasses, wear anti-static work clothes, wear chemical gloves, the workplace concentration exceeds the standard operator should wear filtering gas mask.
4, storage tanks and other pressure equipment set pressure gauges, level gauges, thermometers and should be equipped with pressure, level, temperature remote recording and alarm function of the safety device. Set the rectifier and the press, power supply, pipeline pressure, ventilation facilities or the corresponding absorption device interlocking device. Key tanks and other emergency cut-off facilities.
5, avoid contact with strong oxidizers, alkalis.
6, production and storage areas set up safety warning signs. Prevent gas leakage into the workplace air. Handling of light loading and unloading to prevent damage to the cylinder and accessories. Equipped with the appropriate variety and number of fire-fighting equipment and leakage emergency treatment equipment.
7, hydrogen sulfide production equipment as much as possible closed. Purify the waste water, waste gas and waste residue containing hydrogen sulfide, and discharge them only after reaching the emission standard.
8, into the possible existence of hydrogen sulfide in the workplace should be the first determination of the air in the place of hydrogen sulfide concentration, take ventilation and detoxification measures to confirm the safety of the operation. Operation of personal protective measures, wearing a positive pressure self-contained air respirator, the use of portable hydrogen sulfide detector alarm, operating workers waist tied to the rescue belt or rope. To set up a guardian to do a good job of mutual protection, the occurrence of abnormalities immediately save the poisoned person.
Hydrogen sulfide is a colorless gas that smells like rotten eggs at low concentrations and dulls the sense of smell at high concentrations. Soluble in water, ethanol, glycerol, carbon disulfide. Strong neurotoxicity, strong irritation of mucous membranes, high concentrations of inhalation can occur sudden death, severe poisoning can be left with neurological and psychiatric sequelae. Mainly used in the manufacture of inorganic sulfide, also used for chemical analysis such as identification of metal ions. The gas is heavier than air, can be diffused to a considerable distance at a low place, and will catch fire when it meets an ignition source. Acute poisoning appears eye and respiratory tract irritation, acute tracheobronchitis or peribronchitis, bronchopneumonia, headache, dizziness, fatigue, nausea, impaired consciousness. In severe cases, the degree of impaired consciousness reaches deep coma or vegetative state, with pulmonary edema and multiple organ failure. It is irritating to eyes and respiratory tract. Long-term exposure to low concentrations of hydrogen sulfide can cause neurasthenia syndrome and vegetative nerve disorders.
