Hazard Communication Standard 1910.1200
Subpart Z - Toxic & Hazardous Substances (1910.1000 - 1450)FY2006 Hazard Communication - Written program Hazard Communication - Information & training Hazard Communication - Training initially & for new hazards Standard: 1910. Hazard Communication - Material Safety Data Sheets Hazard Communication - Label identification
Objectives • Hazard Communication Program • Labels and other forms of warnings • Material Safety Data Sheets (MSDS) • Information and training • Health Hazards
Purpose • The purpose of the standard is to make sure that the hazards of chemicals are evaluated • That information concerning their hazards is communicated to employers and employees
Who is covered • OSHA’s Hazard Communication (HazCom) standard applies to general industry, shipyard, marine terminals, longshoring, and construction employment and covers chemical manufacturers, importers, employers, and employees exposed to chemical hazards. Horizontal
Background • The Hazard Communication Standard (HCS) is based on a simple concept--that employees have both a need and a right to know the hazards and identities of the chemicals they are exposed to when working
Background • They also need to know what protective measures are available to prevent adverse effects from occurring • The HCS is designed to provide employees with the information they need MSDS
Employer Requirements-Written Program • Employers must develop a written program that covers at least: • Labels and other forms of warnings • Material Safety Data Sheets • Employee Information and Training
Employer Requirements-Written Program • Employers must develop a written program that covers at least: • A list of the hazardous chemicals known to be present at the facility along with MSDS’s for each chemical • The methods the employer will use to inform employees of the hazards non-routine tasks • The hazards of chemicals in unlabeled pipes
Multi-Employer Workplaces • If employees of other employers could be exposed to hazardous chemicals the program must include: • Methods to provide contractor employees with on-site access to MSDS for each chemical those workers may be exposed to • The methods used to inform other employers of any precautionary measures to be taken for normal and emergency situations • The employers chemical labeling system
Consumer Products Exemption • Any consumer product as defined in the Consumer Product Safety Act where the employer can show that: • It is used in the workplace for the purpose intended • The use results in a duration and frequency of exposure which is not greater than the range of exposures that could reasonably be experienced by consumers when used for the purpose intended
Written Program Availability • The employer must make the written program available, upon request, to: • Employees and their designated representatives • Where work is carried out at more than one location, the program may be kept at the main location
Labels, Tags and Markings • The employer must ensure that each container of hazardous chemicals in the workplace is labeled, tagged or marked with the following: • Identity of the hazardous chemical • Appropriate hazard warnings • This above labeling information is required of the manufacturer so the employer must ensure that the original labels from the manufacturer are on all containers and remain legible
Labels – NFPA Diamond • RED - Flammability • BLUE - Health • YELLOW - Reactivity • WHITE - Special {NFPA – National Fire Protection Association}
Labels - HealthHazard • What the numbers show 0 = No hazard 1 = Slight hazard 2 = Dangerous 3 = Extreme danger 4 = Deadly
Labels –Flammability • What the numbers show 0 = Will not burn 1 = Ignites above 200 degrees F 2 = Ignites below 200 degrees F 3 = Ignites below 100 degrees F 4 = Ignites below 73 degrees F Based on Flash Point {the temperature at which a material gives off enough vapors to sustain ignition}
Labels - Reactivity • What the numbers show 0 = Stable 1 = Normally Stable 2 = Unstable 3 = Explosive 4 = May detonate
Labels - Special Hazard • What the letters show • OX= Oxidizer • ACID = Acid • ALK= Alkali • COR= Corrosive • W= Use No Water • = Radioactive
Blue Red Yellow White Labels - HMIS Protective Equipment A = safety glasses B = safety glasses + gloves C = safety glasses + gloves + synthetic apron D-Z = etc....... {HMIS – Hazard Material Information System}
Container Labeling Exemption for Portable Containers • The employer is not required to label portable containers into which hazardous chemicals are transferred from labeled containers, and which are intended only for the immediate use by the employee who performs the transfer
The employer need not affix new labels to comply with the standard if existing labels already covey the required information
New Hazard Information • Manufacturers, importers, distributors and employers who become newly aware of significant information regarding chemical hazards shall: • Revise the labels for the chemical within three months • Revise the MSDS for the chemical within three months
MSDS kept in other forms • MSDS may be kept in any form including operating procedures • It may be more appropriate to address the hazards of a process rather than individual hazardous chemicals
Employee Information and Training • Employers must provide employees information and training on hazardous chemicals in their work area: • At the time of their initial assignment • Whenever a new physical or health hazard the employees have not previously been trained about is introduced into their work area • Training may cover categories of hazards
Employee Information • Employers must inform employees: • Of the training requirements of this section (1910.1200 (h) Employee information and training.); • Any operations in their work area where hazardous chemicals are present; • The location and availability of the written hazard communication program
Employee Training • Employee training shall include at least: • The means to detect the presence or release of a hazardous chemical in the work area • The physical and health hazards of chemicals in the work area • Measures employees can take to protect themselves • Details of the employers specific program
Hazard Definitions
Chemical ExposureSeverity & Duration • “Acute” effects usually occur rapidly as a result of short-term exposures, and are of short duration • “Chronic” effects generally occur as a result of long-term exposure, and are of long duration
Corrosive • Visible destruction, or irreversible damage to body tissue • Acids • Caustics (or bases) Caustics (or bases) pH Scale Acids 1 7 14
Routes of Exposure Inhalation - Absorbtion - Ingestion - Injection - • Inhalation - most common • Skin absorption • Ingestion • Injection
Health Hazards Toxicity vs. hazard - toxicity is used to describe the ability of the substance to cause a harmful effect. Everything is toxic at some dose.
Health Hazards Toxicity vs. Dose - There is a balance between toxicity and dose. Dose is the amount of something the individual is exposed to or comes in contact with. The lower the toxicity, the greater the dose that can be tolerated without ill effects. The greater the toxicity, the lower the dose that can be tolerated without ill effects.
Chemical Exposure Limits • Time Weighted Average (TWA) based on an 8 hour day. • Ceiling Limits based on maximum exposure. • Exposure Limits are established for all chemicals.
Major Types Corrosives - cause tissue damage and burns on contact with skin or eyes Primary Irritants - cause intense redness or swelling of skin or eyes on contact. No permanent tissue damage Sensitizers- cause an allergic skin or lung reaction Acutely Toxic Materials - cause an adverse effect even at very low doses Carcinogens - may cause cancer Teratogens - may cause birth defects Organ Specific hazards - damage to specific organ systems such as liver or lungs Health Hazards
Health Hazards • Training and communication - knowing how to work safely with chemicals that pose a hazard - i.e. bulletins, MSDS, etc.. THE RIGHT TO KNOW • Environmental monitoring - Industrial Hygiene air sampling • Personal monitoring - check yourself and co-workers for symptoms - i.e. skin rashes, eye or throat irritation, strong odors
Chemicals Used During Sanitation • Detergents • Disinfectants • Sterilants
General Characteristics of Detergents ALCOHOLS (Isopropyl or Ethyl Alcohol) Wide germicidal activity, non corrosive, but poses a fire hazard. Limited residual activity due to evaporation. Alcohols provide limited activity in the presence of organic matter. Not considered effective against bacterial or fungal spores. Excellent for disinfecting instruments or other small objects. Too expensive for general use in the hatchery. Must use as a 70-95% concentration for effectiveness. HALOGENS (Iodines or hypochlorites) Provide wide germicidal activity but are corrosive. Limited activity when in the presence of organic matter. Poor residual activity, low toxicity, but may stain surfaces. Not effective as sporocidal agents. Effective at low concentrations for disinfecting clean, small objects. Low cost but requires frequent applications.
General Characteristics of Detergents QUATERNARY AMMONIUM COMPOUNDS Limited germicidal range. Not sporocidal, effective against vegetative bacteria, fungi and viruses. Reduced efficiency in the presence of organic matter. Limited effectiveness in soaps, detergents and hard water salts. Non-irritating, non-corrosive and low toxicity. Residual activity is limited by the amount of recontamination. Good disinfectant for use on cleaned surfaces. Low cost. PHENOLICS (Single or Multiple) Wide germicidal range, not sporocidal. Low toxicity and low corrosiveness. Very effective in the presence of organic matter. Good residual activity and deodorizer. Low to moderate cost.
General Characteristics of Detergents COAL TAR DISTILLATES ( Cresol and Cresylic Acid) Wide germicidal activity, not sporocidal. Corrosive and toxic at high concentrations. Excellent residual activity with heavy odor. Highly efficient in presence of organic matter. Not well suited for use near eggs or chicks due to noxious gases. Moderately expensive. ALDEHYDES (Glutaraldehyde) Wide germicidal activity, sporocidal and fungicidal. Slight to moderate efficiency in presence of organic matter. Slight residual activity. Moderately toxic. Moderate cost.
General Characteristics of Detergents OXIDIZING AGENTS (Hydrogen peroxide, Potassium Permanganate) Moderate to wide germicidal activity, not sporocidal. Rendered ineffective in the presence of organic matter. Moderately corrosive, limited toxicity. Poor to limited residual activity. More valuable as a cleansing and deodorizing agent. Moderate cost.
Material Safety Data Sheets (MSDS) are one of the most important tools available to employers for providing information, and protection to workers from hazardous chemicals which are used in the workplace. Material Safety Data Sheets (MSDS)
