Leakage emergency treatment
Evacuate the personnel in the leakage contaminated area to the safety area, prohibit irrelevant personnel from entering the contaminated area, and suggest that emergency personnel wear self-contained breathing apparatus and chemical protective clothing.Do not directly contact the leakage, absorb it with sand, shovel it into the bucket, and pour it into an open place for deep burial.Lime shall be sprinkled on the polluted area and washed with a large amount of water. The diluted sewage shall be discharged into the wastewater system.In case of a large amount of leakage, the dike shall be used to collect it, and then it shall be collected, transferred, recycled or discarded after harmless treatment.
Protective measures
Respiratory system protection: gas mask must be worn during production operation or agricultural use.Self contained breathing apparatus shall be worn during emergency rescue or escape.
Others: Smoking, eating and drinking are prohibited at the work site.After work, take a shower and change clothes.Pay attention to personal hygiene.Pre employment and regular physical examination shall be carried out.
First aid measures
Skin contact: Rinse thoroughly with soapy water and clean water.Get medical attention.
Eye contact: open the eyelids and flush with flowing water for 15 minutes.Get medical attention.
Inhalation: leave the site to fresh air.Get medical attention.
