The production equipment producing hydrogen sulfide shall be as closed as possible, and an automatic alarm device shall be set (the concentration of hydrogen sulfide in hazardous areas shall not be judged according to the odor, and it will cause olfactory paralysis when the hydrogen sulfide reaches a certain concentration).
2. The wastewater, waste gas and waste residue containing hydrogen sulfide shall be purified and discharged only after meeting the discharge standard.
3. When entering the closed containers, pits, kilns, trenches and other workplaces where hydrogen sulfide may exist, first measure the concentration of hydrogen sulfide in the workplace, take ventilation and detoxification measures, and then operate after confirming safety. The hydrogen sulfide concentration shall be continuously measured during operation.
4. Personal protective measures shall be taken during operation, gas protective equipment (gas masks are generally used for escape and self rescue) shall be provided, and rescue belts or ropes shall be tied around the waist of the workers. Mutual insurance shall be carried out in the presence of more than 2 persons.
5. Personnel suffering from hepatitis, kidney disease and tracheitis shall not be engaged in hydrogen sulfide operations.
6. Strengthen the training of employees on professional safety knowledge and skills, and improve their self-protection awareness and ability.
Emergency disposal of hydrogen sulfide poisoning:
For devices, equipment and facilities involving hydrogen sulfide, special emergency plans and on-site disposal plans for hydrogen sulfide poisoning shall be formulated. In case of hydrogen sulfide poisoning accidents, rescuers involved in on-site rescue must carry out rescue under the condition of ensuring safety protection. Wear isolation clothing and anti poison equipment (air breathing, etc.), and avoid blind rescue and self poisoning. The patient should be quickly removed from the poisoning site, moved to fresh and well ventilated air, unbuttoned clothes, trousers, etc., inhaled oxygen, used glucocorticoids as early as possible, used antidotes appropriately, and actively treated the rescuers symptomatically. For those who have stopped breathing, artificial respiration should be carried out in a timely manner, and those who have conditions should be intubated and mechanically ventilated in a timely manner.
