Understanding DOT Class 9 Materials: Miscellaneous Hazardous Materials

Image
  Definition of DOT Class 9: Miscellaneous Hazardous Materials Class 9 covers materials which are hazardous for transportation but do not otherwise fall into the Class 1 to Class 8 classifications. Class 9 materials include anesthetic, noxious, or other similar materials which could inhibit the performance of a flight crew member if released. They also include elevated temperature materials, hazardous substances, hazardous waste, and marine pollutants that meet a definition within 49 CFR 171.8 but not a specific Class definition. Relationship Between Class 9 and OSHA Hazard Classifications Since Class 9 is strongly defined more by the material's properties being hazardous in transportation, there is minimal overlap with OSHA Hazard Classification. OSHA has separate Hazards Not Otherwise Classified apart from Physical Hazards and Health Hazards. While PHMSA Class 9 includes materials which are considered elevated temperature material and marine pollutants,

Sodium Carbonate Safety Guide

Image
  What is Sodium Carbonate? Sodium Carbonate, also known as disodium carbonate and soda ash, is an organic sodium salt. It has many uses, ranging from being an ingredient in detergents and cleaners to textile processing to human and veterinary medicine. Sodium carbonate has the CAS Number 497-19-8. Notable Properties of Sodium Carbonate In its natural solid form, sodium carbonate is a colorless crystal and when powered it appears white. What Makes Sodium Carbonate Hazardous? Sodium carbonate is an irritant, with exposure causing irritation to the skin and eyes. There are also reports of repeated sodium carbonate inhalation causing irritation and damage to the respiratory system. Sodium Carbonate Frequently Asked Questions Does sodium carbonate dissolve in water? Yes, sodium carbonate is soluble in water. It will break down into carbonic acid and sodium hydroxide. For more information about sodium hydroxide, see the AHCES Lye Safety Guide . 6 Steps for Safety Step 1: Read the Warnings W

Understanding DOT Class 8 Materials: Corrosive Materials

Image
Definition of DOT Class 8: Corrosive Materials Class 8 covers corrosive materials. The formal definitions associated with Class 8 can be found in 49 CFR 173.136 . Class 8 Corrosives covers both materials that are corrosive to human skin and materials that are corrosive to metal. The hazard of being corrosive to human skin is the primary basis the regulation is written on and is referred to the most within the relevant regulations, due to the risk to human health presented. Class 8 Packing Groups Class 8 is divided into three Packing Groups, labeled Packing Group I, Packing Group II, and Packing Group III in descending order of severity. The primary assignment of the Packing Group is based on how rapidly the material can cause irreversible damage to human skin. Lower Packing Group materials, meaning more dangerous materials, will have accordingly stricter packaging requirements and restrictions associated with them. Relationship Between Class 8 and OSHA Hazard Classifications Materials

Hydrochloric Acid Safety Guide

Image
  What is Hydrochloric Acid? Hydrochloric Acid, also known as muriatic acid, is the aqueous solution of hydrogen chloride dissolved in water. Hydrochloric acid has many uses, ranging from leather tanning and electroplating metals to heavy-duty cleaning applications. Both hydrochloric acid, a liquid, and hydrogen chloride, a gas, have the CAS Number 7647-01-0. Notable Properties of Hydrochloric Acid For safety and handling purposes, hydrochloric acid and hydrogen chloride are often treated interchangeably. Hydrogen chloride reacts readily with water vapor in air, forming vaporous hydrochloric acid. This reaction can also take place within the respiratory system, with inhaled hydrogen chloride forming hydrochloric acid when in contact with the moist parts of the airway and lungs. Likewise, hydrochloric acid can give off irritating hydrogen chloride vapors. Even with the overlap in hazards, there are still some different risks associated hydrochloric acid and hydrogen chloride. What Makes

Understanding DOT Class 7 Materials: Radioactive Materials

Image
  Definition of DOT Class 7: Radioactive Materials Class 7 covers radioactive materials. The formal definitions associated with Class 7 can be found in 49 CFR 173.403 . Class 7 materials are highly specific in regulations associated with them. Only a properly trained professional should be handling and packing Class 7 materials. Types within Class 7 Different types of sub-classifications are used in Class 7. Normal Form is the default type of Class 7 material. There is also a Special Form Class 7 material, which is a non-dispersible solid radioactive material or radioactive material in a sealed capsule, which meets the requirements of the definition . There are Type A and Type B quantities. Type A packages are a form of limited quantity, defined by ranges of radionuclide values. Type B packages have radionuclide values greater than the limits for Type A. These types determine what form of packaging is required for a given shipment of radioactive material. Relationship

Understanding DOT Class 6 Materials: Poisonous and Infectious Substance Materials

Image
  Definition of DOT Class 6: Poisonous and Infectious Substance Materials Class 6 covers poisonous and infectious substance materials. The formal definition for 6.1 poisonous materials can be found at 49 CFR 173.132 and the formal definition for 6.2 infectious substances can be found at 49 CFR 173.134 . Class 6 Divisions Class 6 materials are grouped into two divisions. Division 6.1 Division 6.1 materials are poisonous materials, which can be toxic to humans through the exposure routes of oral toxicity, dermal toxicity, and/or inhalation toxicity. Division 6.2 Division 6.2 materials are infectious substances, consisting of pathogens including bacteria, viruses, parasites, and fungi. Division 6.2 materials are further subdivided into Category A and Category B substances. Category A substances can cause long-term, permanent injury or life-threatening illness. Category B substances do not have a risk of causing long-term, permanent injury or life-threatening illness.

The Written Hazard Communication Program - Safety Requirement and Safety Tool

Image
  An Introduction to the Written Hazard Communication Program A Written Hazard Communication Program (WHCP) is a technical and regulatory document that is used to describe how the criteria for compliance with OSHA's Hazard Communication Standard (HCS) are being met by an employer. The full text for the Hazard Communication Standard can be found at 29 CFR 1910.1200 and the requirements for the Written Hazard Communication Program are found at 1910.1200(e) . What is a Written Hazard Communication Program (WHCP)? The WHCP is a written document which describes how an employer will meet the requirements for labels and other forms of warning, safety data sheets, and employee information and training that are necessary at the workplace. The WHCP must also contain a list of the hazardous chemicals known to be present in the workplace and the methods the employer will use to inform employees of hazards associated with non-routine tasks. The WHCP has important additions if there a multi-emp
