Chemical agents hazard labels

Chemists and other scientists collectively nse thonsands of chemicals in their laboratory work, but COCs pose a particular risk to the general pnblic if they are acquired by people who wish to inflict harm. Some COCs can be used as precursors to make potentially deadly chemical agents or illicit drugs. Other chemicals have hazardous properties that can pose risks to laboratory personnel, especially if they are unaware of the properties. The United Nations has developed a system, the Globally Harmonized System for Classification and Labeling of Chemicals, for classifying chemicals according to their hazardous properties. In that system the most hazardous chemicals make up Hazard Class 1 these COCs should be kept secure from theft or diversion, and there are laboratory security measures that can help to prevent such diversions. 

DOT CLASSIFICATION 2.2 Label Nonflammable Gas, Oxidizer SAFETY PROFILE A poison. Mildly toxic by inhalation. Prolonged absorption may cause mottling of teeth, skeletal changes. Severe explosion hazard by chemical reaction with reducing agents, particularly when under pressure. A ver dangerous fire hazard a very powerful oxidizer otherwise inert at normal temperamres and pressures. 

DOT CLASSIFICATION 8 Label Corrosive DOT Class 8 Label Corrosive, Poison SAFETY PROFILE Confirmed human carcinogen. A poison. Moderately toxic by inhalation. A corrosive irritant to skin, eyes, and mucous membranes. A very dangerous fire hazard by chemical reaction with reducing agents and carbohydrates. A severe explosion hazard by chemical reaction with acetic acid, acetic anhydride, acetonitrile, acrolein, acrylic acid, acrylonitrile, aUyl... 

Most research laboratories will not have occasion to ship significant quantities of these materials they are usually recipients of shipments of these substances. However, should the need arise to ship hazardous chemicals, knowledge of the provisions of 49 CFR Parts 172-173 will be helpful. The shipper s agent should also be contacted and may be able to provide the required labels.
