Introduction to the Federal Hazard Communication Standard • The Hazard Communication (HAZCOM) Standard was issued by the Occupational Safety and Health Administration (OSHA) in 1983 and revised in 1987 • Executive Order 12196 of 1980 and 29 CFR Part 1960 provide the authority for implementing this Standard within the Federal sector • HAZCOM requires that you be: • Informed about hazardous chemicals in your unit/workplace • Trained to work safely with these materials
HAZCOM Goals The Hazard Communication Standard was developed to - • Reduce the incidence of illness and injury caused by chemical hazards • Identify and evaluate chemical hazards • Communicate information about chemical hazards to commanders, managers, and workers
Chemical Forms and Exposure Hazards • HEALTH HAZARDS can cause illness or injury when you are exposed to hazardous chemicals by breathing, swallowing, skin contact, or eye contact • IRRITANTS can cause injury to whatever part of your body they contact -- e.g., skin, eyes, lungs • Repeated skin contact with igniting explosives or flammable liquids, such as MOGAS can cause skin irritation. Breathing the vapors slows down the nervous system • ASPHYXIANTS cause suffocation by displacing oxygen in air
Chemical Forms and Exposure Hazards • PHYSICALHAZARDS can cause explosions, fires, violent chemical reactions, or other hazardous situations • All compressed gases present a physical hazard because they contain stored energy which can turn the gas cylinder into a powerful rocket • Some substances are water-reactive and create a hazardous chemical reaction when mixed with water (water-reactive) • Spontaneous combustible chemicals present a fire hazard • Corrosives can eat through metals and other materials. They also present a HEALTH hazard because they can eat away body tissues, causing burns
Chemical Forms and Exposure Hazards Chemical materials exist in one of three basic physical forms - • SOLIDS, such as plastic, hold their shape. They become airborne as FUMES or DUSTS. • LIQUIDS take the shape of their container. They become airborne as MISTS or VAPORS. • GASES have no definite shape. They can be compressed, and they expand to fill containers. Air is an example of a gas that is everywhere. Gases become airborne if not contained.
Chemical Forms and Exposure Hazards Airborne chemical hazards - • DUST is made up of tiny airborne particles formed as solids are broken up, e.g., grinding, sanding, sweeping. • SMOKE is a mixture of fire gases and airborne dust or fume particles. It is found in combustion or burning processes. • FUME particles are formed by cooling vapors from operations where solids have been melted as in soldering. • VAPORS form above exposed liquid surfaces as the liquid evaporates. • MISTS are formed as liquids are agitated or sprayed under pressure • GASES may be compressed for use in a particular operation such as welding, or they may be a by-product of the process itself, as in gases from engine exhaust.
Chemical Forms and Exposure Hazards The DEGREE OF HAZARD depends on - • TOXICITY of the chemical - Low, medium, and high • EXPOSURE ROUTE - • Breathing/inhalation • Ingestion/swallowing • Skin/eye contact • Skin absorption • DOSAGE - How much, how long, how often • INDIVIDUAL DIFFERENCES - Age, size, allergies, etc.
Types of Physical and Health Hazards PHYSICAL HAZARDS include - • COMPRESSED GASES - Contains a lot of stored energy • EXPLOSIVES - cause a sudden release of pressure and heat • FIRE HAZARDS - ignite and burn easily or cause/support fire • Pyrophorics - ignite spontaneously in air below 130ºF • Flammable Liquids - ignite easily below 100ºF • Combustible Liquid - ignite easily at or above 100ºF, but below 200ºF • Oxidizers - supply oxygen required to start or support fire • UNSTABLE/REACTIVE CHEMICALS - produce or release hazards under commonly occurring temperatures, pressures, or light conditions
Types of Physical and Health Hazards • HEALTH HAZARDS include - • IRRITANTS - cause reddening, itching, or other irritation • CORROSIVES - burn or eat away body tissues on contact • CRYOGENICS - freeze body tissue on contact • TARGET ORGAN - chemicals that damage a specific organ • SENSITIZERS - cause an allergic-like response • CARCINOGENS - cause cancer • REPRODUCTIVE HAZARDS - target the reproductive system causing sterility, miscarriages, fetal injury, or birth defects • MUTAGENS - damage genes in egg or sperm cells • TERATOGENS - damage the fetus during development
Controlling Chemical Hazards Three basic methods of controlling chemical hazards • ENGINEERING CONTROLS • Substitution - replacing a chemical, process, or piece of equipment with a less hazardous or more efficient one • Isolation - enclosure, barrier, or safe distance from exposure • General Ventilation - fresh air make-up to reduce exposure • Local Exhaust Ventilation - capturing an airborne hazard as it is released and taking it out of the workplace • PERSONAL PROTECTIVE EQUIPMENT (PPE) - gloves and clothing, eye and face protection, respiratory protection • ADMINISTRATIVE CONTROLS - operating procedures, markings, warnings
Introduction to MSDSs and MSDS Hazard Information Every Material Safety Data Sheet (MSDS) must contain - • Name, address, and telephone number of the party responsible for preparing or distributing the MSDS, who can provide additional information on the hazardous chemical and appropriate emergency procedures. • Name of the chemical material as it appears on the warning label and Hazardous Chemical Inventory in your unit/workplace. • Health hazards of the chemical, including signs and symptoms of exposure. • Precautions for safe handling and use. • Any applicable controls measures.
Introduction to MSDSs and MSDS Hazard Information • HEALTH HAZARD information is found in the following areas of the MSDS - • Hazardous Ingredients Section • Health Hazard Data Section • Control Measures Section • PHYSICAL HAZARD information within the MSDS appears in - • Fire and Explosion Hazard Data Section • Reactivity Data Section; and • Precautions for Safe Handling and Use
Using Labels and the Hazardous Chemical Inventory Warning labels must include - • The name and identity of the chemical that matches the name and identify on the MSDS and Hazardous Chemical Inventory • All appropriate hazard warnings, including target organ health effects. • Labels on containers that leave the workplace/center must also contain the name and address of the responsible party. • Placards or bin labels can be used for stationary containers as long as the placard clearly identifies the containers to which it applies, and provides the same information required for any other type of hazard warning label. • Use DD Forms 2521 and 2522 (Hazardous Chemical Warning Label) where needed.
Using Labels and the Hazardous Chemical Inventory • The Hazardous Chemical Inventory must - • Name all hazardous chemical materials currently found in your workplace/center. • Containers of materials on the Hazardous Chemical Inventory must be labeled, tagged, or placarded and MSDSs must be available for every material on the inventory. • Identify nomenclature, National Stock Number (NSN), and manufacturer. • Index list corresponding to MSDS filing sequence.
Hazardous Material Information System (HMIS) • HAZARDOUS MATERIAL INFORMATION SYSTEM - (DOD 6050.5-L/LR CD-ROM) • Used to acquire, review, store, and disseminate selected information on hazardous materials • Defense Logistics Agency (DLA) designated executive agent for HMIS • Accessible by National Item Identification Number (NIIN), National Stock Number (NSN), trade name and/or part number, hazard characteristic code, hazardous ingredients, and manufacturer/distributor commercial and government entity (CAGE) code • HMIS Data Bank includes information such as - • MSDS Transportation Disposal Labeling
HAZCOM Training/Orientation and Documentation • Documentation - All training/orientations pertaining to HAZCOM must be documented and retained on file for a minimum of 10 years (Exposure records 30 years) • Training/Orientation - • Initial when program/plan is completed • Newcomer orientation • When “Process” changes • Covers labeling/ID, Inventory, MSDS review, location to find information pertaining to hazardous chemicals (location, location, location) • Includes methods and observations that may be used to detect the presence of a hazardous chemical “THE END”
