“ Hazardous communication RIGHT TO KNOW” Program is abreviated as “ HAZCOM ” This program is not intended to tell you how to do your jobs. It is not a technical chemical safety course. It’ simply Hazard Communication
Why do you need to know this information? The 29 CFR 1910.1200 says: Everyone working with/around Hazardous materials has the right And the Responsibility to be aware of the hazards and proper safe Work procedures for hazardous materials used or produced in their work area. The primary objective is for you to know how and where to find specific hazard information.
Explain the uses of hazard
Describe signs/symptoms of exposure to Hazardous Materials
Describe recommended first aid treatment
Explain Emergency procedures
Explain proper safe working procedures/conditions

Mode of Entr y – Commonly , Toxic Materials contact the skin, enter respiratory tract/Digestive System. Physical Condition - Are you Ill? Has your body been damaged by a previous assault. Dose – How much of the chemical was absorbed by your system? Duration – How long were you exposed to the chemical? Sensitivity – How sensitive are you to the chemical?
Combined Effects - What other chemicals were you exposed to? Stress – Were you under any physical or mental stress during or after the exposure? Other – sex, race Temp, altitude, and many other parameters could affect toxicity

Secondary Containers Are not required to be labeled if used Immediately by one person. Must be labeled if used by more than one person . Must be labeled if used/left for more than one shift .
Material Safety Data Sheet (MSDS) 29 CFR 1910.1200. Standard Prepared by a chemical’s manufacture or importer to provide detailed information about the chemicals characteristics, potential hazards and methods for safe use, handling, and storage of the material .
Material Safety Data Sheets Answer a series of four questions 1. What is the material and what do I need to know. 2. What should I do If a hazardous situation occurs. 3. How can I prevent hazardous situations from occurring. 4. Is there any other useful information about this chemical.

Work Area Chemical Storage - Purchase only quantities that can be used in a reasonably short time - Limit amounts kept in Labs/Work areas - Store according to chemical classification - Do not store alphabetically - store in closed cabinets
- Store close to floor rather than above head level - If stored on open shelves, keep to rear rather than on front edge - Do Not Store inside hoods - If not being used, get rid of it!
Signs and symptoms of exposure Consider routes of entry and length of exposure; - External Redness Swelling itching pain
Signs and symptoms of exposure - Internal Nausea Lightheadedness Headaches Difficulty Breathing Heart Palpitations

Safe Work Procedures * Written Procedures * Container Labels * Personal Protective Equipment (PPE) * Equipment Use * Housekeeping * Storage * Horseplay * Personal Habits
Definitions Acids – A corrosive chemical that proteinizes upon contact with body tissue and causes immediate pain. Bases – A corrosive chemical that does not proteinize upon contact with body tissue and does not cause Immediate pain. Carcinogens - Substances which under favorable conditions through direct or indirect action, either externally or internally, act on healthy cells to cause a metamorphosis and bring about a rapid proliferation of cellular elements and the development of structure abnormalities. Chemical – Means any element, chemical compound or mixture of elements and/or compounds
Compressed Gas – Non Flammable materials which have a PSIA greater than 40 at 70*F, or a PSIA greater than 104 at 104*F, or those Flammable materials which have a PSIA greater than 40 at 100*F. Those with sufficiently high toxicity are class “A” poisons and receive a Poison gas label. All flammable gas,liquefied or non-liquefied and dissolved have flash points below room temperature. It’s impossible to avoid forming a flammable mixture if any leaks into the air. Container – Means any bag, barrel, bottle, box, can, cylinder, drum Reaction vessel, storage tank or the like that contains hazardous chemical .
For purpose of this section , pipes or piping systems are not considered as containers. Corrosive – Any chemical or substance that by direct chemical action is injurious to body tissue or erodes metal. Employee – Means a worker employed by an employer who may be exposed to hazardous chemicals under normal operating conditions or foreseeable emergencies, including, but not limited to, production workers, line supervisors, and repair or maintenance personnel. Office workers, grounds maintenance and security personnel or non resident management are generally not included. Unless their job performance routinely involves potential exposure to hazardous chemicals.
Explosive – Substances under which certain conditions of shock, temperature or chemical reaction decompose with violent rapidity, usually releasing large quantities of gasses and heat. Exposure/ Exposed – Contact with a hazardous chemical in the course of employment through any route of entry (inhalation, ingestion, skin contact or absorption, etc.) and includes potential (e. g., accidental or possible) exposure. Flammable Liquids – A liquid whose vapor can form an ignitable mixture with air. The liquid is the fuel, the surrounding atmosphere is the oxidizer. For the mixture to burn an ignition source must be present.
Foreseeable Emergency – Any potential occurrence such as, but not limited to, equipment failure, rupture of containers, or failure of control equipment which could result in an uncontrolled release of a hazardous chemical into the workplace. Hazard warning – Any words, pictures, symbols, or combination thereof appearing on a label or other appropriate form of warning which convey the hazards of the chemical(s) in the container(s). Hazardous Chemical – Any chemical which is a physical or health hazard.
Health hazard – Means a chemical for which there is a statistically significant evidence on at least one study conducted in accordance with established scientific principles that acute or chronic health effect may occur in exposed employees. The term “health Hazard” includes chemicals which are carcinogens, toxic or highly toxic agents, reproductive toxins, irritants, corrosives, sensitizes, hepatotoxins, nephrotoxins, neurotoxins, agents which act on the hematopoietic system, and agents which damage the lungs, skin, eyes or mucous membranes
Identity – Means any chemical or common name which is indicated on the material safety data sheet (MSDS) for the chemical. The identity used shall permit cross-references to be made among the required list of hazardous chemicals, the label and the MSDS. Label – Means any written, printed or graphic material displayed on or affixed to containers of hazardous chemicals. Material Safety Data Sheets (MSDS) –- Means written or printed material from manufacture prepared in accordance with the OSHA 29 CFR 1910.1200. Standard.
Oxidizer/Reactive – Any chemical That increases the burning rate of material by readily yielding oxygen or other oxidizing gas; or enters into a violent reaction during which the spontaneous liberations of heat/gas is too rapid to be safely dissipated. Physical hazard – A chemical for which there is scientifically valid evidence to show that it is combustible, (such as a compressed gas), explosive, flammable, an organic peroxide, oxidizer, pyrohoric, unstable (reactive) or water reactive. Radioactive – Having the property of emitting particles or radiation from an atomic nucleus such as alpha, beta or gamma rays, as it is the case with uranium, radium, thorium, etc.
Toxic – Any chemical which when ingested, inhaled, absorbed, applied to, injected into or developed within the body in relatively small amounts, may cause damage to structure and otherwise disturb the body’s functions. Use – to package, handle, react or transfer. Work Area – A room or defined space in a workplace where hazardous chemicals are produced or used, and where employees are present.
