Sodium Dichromate Matters Needing Attention

Overview of risk

Health hazards: acute poisoning: inhalation can cause acute respiratory tract irritation symptoms, epistaxis, hoarseness, nasal mucosa atrophy, sometimes asthma and cyanosis. Severe cases may develop chemical pneumonia. Oral administration can stimulate and corrode the digestive tract, causing nausea, vomiting, abdominal pain, bloody stool, etc.; in severe cases, dyspnea, cyanosis, shock, liver damage and acute renal failure may occur. Chronic effects: contact dermatitis, chromium ulcer, rhinitis, nasal septum perforation and respiratory tract inflammation.

Explosion hazard: the product is combustion supporting, carcinogenic, strong corrosive, irritant, and can cause burns to human body.

First aid measures

Skin contact: take off contaminated clothes and wash skin thoroughly with soapy water and water.

Eye contact: lift the eyelids and rinse with flowing water or normal saline. See a doctor.

Inhalation: quickly leave the site to fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. See a doctor.

Ingestion: gargle with water and wash stomach with water or 1% sodium thiosulfate solution. Give me milk or egg white. See a doctor.

Fire fighting measures

Hazard characteristics: strong oxidant. In case of strong acid or high temperature, oxygen can be released to promote the combustion of organic matter. It reacts violently with nitrate and chlorate. When water is mixed with sodium sulfide, it can cause spontaneous combustion. There is a risk of combustion and explosion when contacting or mixing with organic matter, reducing agent and inflammable materials such as sulfur and phosphorus. It has strong corrosivity.

Harmful combustion products: may produce harmful toxic smoke.

Fire fighting method: fog water and sand are used to extinguish the fire.

Emergency treatment of leakage

Emergency treatment: isolate the contaminated area and restrict the access. It is suggested that emergency treatment personnel should wear dust masks (full face masks) and gas protective clothing. Do not let the leakage come into contact with organic matter, reducing agent and inflammable substance.

Small amount of leakage: collect with clean shovel in dry, clean and covered container.

Large amount of leakage: collected and recycled or transported to the waste disposal site for disposal.
