Health effects of acute exposure • The main routes of exposure to hydrogen chloride are via inhalation, or skin or eye contact and exposure to hydrochloric acid is predominantly by ingestion, or skin or eye contact • Inhalation may cause irritation to nose and upper respiratory tract, ulceration, coughing, chest tightness and shortness of breath. Higher concentrations cause tachypnoea, pulmonar...

Aerospace design engineers have long sought concrete data with respect to the thermal safety of materials in contact with human skin. A series of studies on this subject has been completed and some of the results have been reported earlier. In these studies over 2,000 observations were made of pain threshold during contact with materials at elevated temperatures. Six materials were used represe...

Contact allergy is caused by a wide range of chemicals after skin contact. Its clinical manifestation, allergic contact dermatitis (ACD), is developed upon repeated contact with the allergen. This perspective focuses on two areas that have yielded new useful information during the last 20 years: (i) structure-activity relationship (SAR) studies of contact allergy based on the concept of hapten-...

 Toxic by all routes of exposure – inhalation, ingestion, skin contact  Carcinogenic in humans  Inhalation of vinyl chloride causes coughing, wheezing and breathlessness, headache, ataxia, drowsiness and coma  Ingestion of vinyl chloride causes nausea, vomiting, diarrhoea, abdominal pain, and haematemesis may occur.  Skin contact causes irritation, pain, burns and contact dermatitis. Rapid...

CONTACT WITH CORAL MAY CAUSE A RARE TYPE OF CONTACT DERMATITIS, AND THE RESULTING SKIN REACTION CAN BE DIVIDED INTO DIFFERENT REACTIONS: the acute, delayed and chronic types of coelenterate dermatitis. Granulomas of delayed skin reactions have rarely been reported. Herein, we report on a rare case of a delayed reaction of the skin to coral injury, and the patient displayed superficial granuloma...
