A report on Chromic acid

A man who fell into a barrel of Chromic acid while at work Monday followed correct procedures and is recovering in a Grand Rapids, Mich., hospital, his employer said.

The man, 45, is a 10-year employee of Lacks Enterprises in Grand Rapids and was performing a maintenance function when he slipped and fell into a tank of diluted chromic acid(CAS: 7738-94-5), a toxic and carcinogenic element of the chrome-plating process, the news website MLive.com reported Monday.

It added only the man's legs were dunked in the acid.Jim Green, human resources director of the firm, said the employee was wearing a safety harness and other appropriate equipment when the accident occurred, and fellow employees hosed the victim down according to protocol.

"I spoke to him personally today, and hope to be in touch with him again soon. We anticipate a full recovery," Green said of the employee's injuries.

Chromic acid(CAS:7738-94-5)was widely used in the instrument repair industry, due to its ability to "brighten" raw brass. A chromic acid dip leaves behind a bright yellow patina on the brass. Due to growing health and environmental concerns, many have discontinued use of this chemical in their repair shops.

In this article, we can talk something about the Potential Health Effects of chromic acid.

Inhalation: Corrosive. Extremely destructive to tissues of the mucous membranes and upper respiratory tract. May cause ulceration and perforation of the nasal septum. Symptoms may include sore throat, coughing, shortness of breath, and labored breathing. May produce pulmonary sensitization or allergic asthma. Higher exposures may cause pulmonary edema. 

Ingestion: Corrosive. Swallowing can cause severe burns of the mouth, throat, and stomach, leading to death. Can cause sore throat, vomiting, diarrhea. May cause violent gastroenteritis, peripheral vascular collapse, dizziness, intense thirst, muscle cramps, shock, coma, abnormal bleeding, fever, liver damage and acute renal failure. 

Skin Contact: Corrosive. Symptoms of redness, pain, and severe burn can occur. Dusts and strong solutions may cause severe irritation. Contact with broken skin may cause ulcers (chrome sores) and absorption, which may cause systemic poisoning, affecting kidney and liver functions. May cause skin sensitization. 

Eye Contact: Corrosive. Contact can cause blurred vision, redness, pain and severe tissue burns. May cause corneal injury or blindness. 

Chromic acid Exposure: Repeated or prolonged exposure can cause ulceration and perforation of the nasal septum, respiratory irritation, liver and kidney damage and ulceration of the skin. Ulcerations at first may be painless, but may penetrate to the bone producing "chrome holes." Known to be a human carcinogen.
