Invasion routes: inhalation, ingestion and percutaneous absorption.
health hazard: it has * * effect on respiratory tract and systemic toxicity, which can cause lung, liver and brain damage. If pulmonary edema is not rescued in time, it can cause death.
Acute poisoning: Early manifestations include headache, dizziness, unsteady gait, blurred vision, eye * * *, nausea, palpitation, chest tightness and shortness of breath. Delayed symptoms mainly include obvious chest tightness, shortness of breath, severe dyspnea, cyanosis, cough, coughing up a lot of pink foam sputum, tachycardia, etc. These are the manifestations of pulmonary edema and diffuse interstitial pneumonia. Toxicological data and environmental behavior
Toxicity: highly toxic.
acute toxicity: LD539mg/kg (in rat cavity membrane); 63mg/kg (subcutaneous in rats); LC535ppm, 7 hours (inhaled by rats)
Carcinogenicity: Nickel and its compounds have been confirmed as carcinogens by IARC.
hazard characteristics: spontaneous combustion when exposed to air. Strong decomposition and combustion in case of open flame and high heat. It can react strongly with oxidant, air, oxygen and bromine, causing combustion and explosion.
combustion (decomposition) product: carbon monoxide. 22 on-site emergency monitoring method
Portable chemiluminescence detector; Gas detection tube method 23 laboratory monitoring method

determination method of harmful substances in air (second edition) edited by Chen Anzhi, and environmental standard 24 edited by Hang Shiping
China (TJ3679) The maximum allowable concentration of harmful substances in the air of workplace is .1mg/m3 25, and emergency treatment for leakage
. It is recommended that emergency personnel wear positive pressure self-contained breathing apparatus and chemical protective clothing specially recommended by the manufacturer (completely isolated). Do not directly contact with the leakage, and stop the leakage under the condition of ensuring safety. Spray mist can reduce evaporation, but it can't reduce the flammability of leakage in confined space. Mix and absorb with sand or other nonflammable adsorbents, and then collect and transport them to waste disposal sites for disposal. If there is a large amount of leakage, it will be contained by the dike, and then collected, transferred, recovered or discarded after harmless treatment. 26 protective measures
respiratory system protection: you must wear a gas mask when you may come into contact with its vapor. Positive pressure self-contained breathing apparatus should be worn during emergency rescue or escape.
eye protection: wear chemical safety glasses.
physical protection: wear corresponding protective clothing.
hand protection: wear chemical-resistant gloves.
others: smoking, eating and drinking are prohibited in the workplace. After work, take a shower and change clothes. Store clothes contaminated by poisons separately and use them after washing. Conduct pre-employment and regular physical examination. 27 first aid measures
skin contact: take off contaminated clothes and rinse with flowing water.
eye contact: lift the eyelid immediately and rinse with flowing water.
inhalation: leave the site quickly and go to fresh air. Pay attention to keep warm and keep the respiratory tract unobstructed. Give artificial respiration if necessary. See a doctor.
ingestion: people who take it by mistake should drink plenty of warm water to induce vomiting and seek medical treatment.
