2. HAZARD COMMUNICATION 8 CCR 5194
Protects employees from hazardous chemicals.
Informs employees about chemical hazards.
Provides precautions and protective measures when using, handling and contacting chemicals.
Important points:
Hazard Communication or Employee Right to Know was enacted in 1985.
The purpose of the act is to:
Protect employees from needless chemical exposure.
Provide a mechanism for employees to know about the hazards associated with chemicals that they work with.
The following products are exempt from the act:
-Hazardous Waste
-Tobacco or tobacco products
Wood or wood products
Foods, drugs or cosmetics
Retail food sale
Consumer Products (This applies to chemicals purchased at a consumer store. However, if these products are used in the work environment, they must have a MSDS. For example, bleach purchased at a grocery store will not require a MSDS. But if you use this product in the workplace, the standard applies.)
The use of a substance in compliance with regulations of the Director of Food and Agriculture.

10. HAZARD TERMS Corrosives Flammables Explosives Pressure Toxicity
Corrosives- Materials that burn body tissues, such as Hydrochloric Acid, Sodium Hypochlorite (bleach), Nitric Acid, Sulfuric Acid.
Flammables-Materials that easily ignite or burn rapidly or intensely such as:
Acetone, Methanol, Gasoline, Xylene.
Explosives-Materials that violently release large quantities of gas and heat.
Many explosions result in fires. Explosion hazards and flammable hazards are frequently considered together.
Pressure can also be developed in a closed container due to decomposition or reaction of the content. An example of a pressure hazard is broken valve on a compressed gas cylinder. Escaping gas can propel a cylinder like a rocket.
Toxicity-A substance with the potential of injury by direct chemical action with body systems. Toxic substances interfere with the function of cells in body tissues.

11. HAZARD DEFINITION AND TERMS
Routes of Entry
Chemicals may enter the body in four ways:
Inhalation (breathing)
Ingestion (swallowing)
Absorption through the skin
Injection

12. HAZARD DEFINITION AND TERMS
Dose and Dose Effects
Dose: The amount of material an individual is exposed to.
The dose effects depend on the concentration of material over a period of time.
Acute effects: Occur rapidly as a result of short-term exposures, and are of short duration.
Chronic effects: Occur as a result of long-term exposure, and are of long duration.
The amount of the material to which an individual is exposed to is called the Dose.
The dose effects are dependent on the concentration of the material that gets into the body over a period of time, or concentration x time.
The response depends on the dose and the effects on the body. This may lead to irritation, illness or death.
A high concentration for a short period of time is an acute effect.
A continued smaller exposure for a long period of time is a chronic effect.

13. MATERIAL SAFETY DATA SHEET
Material Safety Data Sheets (MSDSs) provide detailed health and safety information and precautions for handling hazardous substances, including emergency and first aid procedures.
All MSDSs must contain information required by OSHA MSDS form 174.
The Right to Know law requires hazardous substance manufacturers to develop MSDSs for substances they produce or import.
Distributors also must provide MSDSs.
MSDSs have been distributed at District sites for the following operations:
Office Products
Custodial Products
Food Services Products
Maintenance Products
Automotive Repair Products
Science Chemical Products
MSDSs must be available for all employees in their work locations for review during each work shift. If MSDSs are not available, or new hazardous substances are in use, please contact OEHS.
All District employees have the right to obtain copies of MSDSs without fear of termination, discrimination or retaliation.

Incompatibility
Hazardous decomposition
This section provides information regarding chemicals that “react” with certain materials or conditions, and may cause a dangerous reaction.
Stability: The likelihood or probability of a chemical undergoing a violent reaction (e.g. explosion, spontaneous combustion) in response to an environmental stimulus, such as heat, shock, moisture, or another chemical. Ordinary table salt (sodium chloride) is very stable; metallic sodium and chlorine gas are both highly reactive and quite unstable.
Incompatibility: The probability of two chemicals combining with each other and producing either a dangerous reaction (e.g. fire, explosion, etc.) or a highly toxic by-product (see “bleach and ammonia” , p. 22).
Hazardous Decomposition: The gradual breakdown of a chemical (e.g. during long storage periods) wherein the formation of unstable chemical by-products may cause spontaneous combustion, an explosion or some other dangerous reaction to occur.

22. REACTIVE CHEMICALS
An example of two incompatible chemicals is bleach and ammonia.
Bleach and ammonia mixed together can produce a dangerous (sometimes fatal) gas called phosgene.

Another example of a label with warnings and caution phrases.

31. LABELS
The National Fire Protection Association (NFPA) utilizes a diamond divided into four color coded sections:
Blue - Health Hazard
Red - Flammability
Yellow - Reactivity Hazard
White - Other Hazard Information
Fire Department Placard
This placard is designed to protect fire fighters.
The colors relate to the reactions of chemicals in fire conditions.

32. LABELS Within each section, a number ranks the degree of hazard:2
LABELS 1 3
Within each section, a number ranks the degree of hazard:
0 - No or Minimal Hazard
1 - Slight Hazard
2 - Moderate Hazard
3 - Serious Hazard
4 - Extreme Hazard
In this situation:
Blue Section -1 (Health Hazard) TYPE of POSSIBLE INJURY: The materials in the building would cause irritation but only minor residual injury, even if no treatment is given.
Red Section -2 (Flammability) SUSCEPTIBILITY OF MATERIALS TO BURNING: The materials must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur.
Yellow Section-3 (Reactivity) SUSCEPTIBILITY TO RELEASE OF ENERGY: The materials are capable of detonation or explosive reaction but require one or more of the following:
A strong initiating source
Heating under confinement before initiation
Exposure to water

33. LABELS
The white section alerts the user to special hazards that a material may possess, such as:
Water reactivity
Strong oxidizer
Corrosivity
Radioactivity
The bottom space is primarily used to identify unusual reactivity with water. A W with a line through its center alerts fire fighting personnel to the possible hazard in the use of water.
Other example of symbols are shown here.

34. LABELS
The Hazardous Material Identification System (HMIS) is similar to the NFPA. The color and numbering codes are identical. HMIS uses a color bar system with ranking for the level of protection:

35. REVIEW What color indicates fire or explosive hazards? Red
