Study Notes

Hazard Communication (OSHA 29 CFR 1910.1200)

Employees have the right to know about health and physical hazards in the workplace, and the precautions to prevent exposure.
Requirements:
- Written Hazard Communication Program
- List of Hazardous Chemicals in the Workplace
- Labeling (manufacturer's label, workplace labeling)
- Safety Data Sheets (SDSs)
- Employee training

Health Hazard Definition

"Health hazard" means a chemical posing one of these effects:
- Acute toxicity (any route of exposure)
- Skin corrosion or irritation
- Serious eye damage or eye irritation
- Respiratory or skin sensitization
- Germ cell mutagenicity
- Carcinogenicity
- Reproductive toxicity
- Specific target organ toxicity
- Hepatotoxins
- Nephrotoxins
- Neurotoxins
- Agents that act on the hematopoietic system
- Agents that damage lungs, skin, eyes, or mucous membranes
- Aspiration hazard

Physical Hazard Definition

"Physical hazard" means a chemical posing one of these effects:
- Explosive
- Flammable (gases, aerosols, liquids, or solids)
- Oxidizer (liquid, solid, or gas)
- Self-reactive/pyrophoric (liquid or solid)
- Self-heating
- Organic peroxide
- Corrosive to metal
- Gas under pressure
- Substance which in contact with water emits flammable gas

Hazard Classification

Each chemical must be evaluated to determine if it's hazardous according to the definition.
Classification should be based on scientific evidence and comparing data with published criteria in the appendices to the standard.
The outcome of the hazard classification determines the signal word and hazard statements for the label and SDS.
Mixtures must be classified as a whole, not individual components.

Labeling Requirements

Based on the classification, the chemical manufacturer/importer must provide specific information on each container:
- Product identifier
- Signal word (Danger or Warning)
- Hazard statement(s)
- Precautionary statement(s)
- Pictogram(s)
- Name, address, and phone number of the chemical manufacturer/importer/responsible party

Product Identifier

The name or number used for a hazardous chemical on a label or in the SDS, providing a unique way to identify the chemical and cross-reference with other hazardous chemicals, labels, and SDSs.

Signal Word

Indicates the severity level of a hazard; Danger (for more severe hazards) or Warning (for less severe hazards).
The word used is specified in Appendix C based on the hazard classification.

Hazard Statement

Describes the specific hazards for each level of hazard within each hazard class (from Appendix C, e.g., for flammable liquids).
- Category 1: Extremely flammable liquid and vapor.
- Category 2: Highly flammable liquid and vapor.
- Category 3: Flammable liquid and vapor.
- Category 4: Combustible liquid.

Precautionary Statements

Selected from tables in Appendix C, based on classification to describe required actions to prevent, respond to, store, and dispose of hazardous chemicals.
Four types of precautionary statements: Prevention, Response, Storage, Disposal.

GHS Pictograms

Standardized hazard symbols used to quickly communicate potential dangers.
- Flammable, Corrosice, Explosive, Compressed Gas, Oxidizing, Toxic, Health Hazard, Harmful/Irritant, Dangerous for the environment.

Pictogram Examples

Corrosion: Corrosive to metals, skin corrosion/irritation, serious eye damage/irritation.
Flame: Flammable gases, aerosols, liquids, solids, self-reactives, pyrophoric liquids and solids, self-heating substances, and substances emitting flammable gases in contact with water, Organic peroxides
Skull and Crossbones: Acute toxicity (oral, inhalation, or dermal routes).
Exclamation Mark: Acute toxicity, skin irritation/corrosion, serious eye damage/irritation, skin sensitizer.
Health Hazard: Respiratory sensitizer, Germ cell mutagenicity, Carcinogenicity, Toxic to reproduction, Aspiration hazard.
Flame over Circle: Oxidizing gases, liquids, solids.
Gas Cylinder: Compressed gas, liquefied gas, refrigerated liquefied gas, dissolved gas.

Safety Data Sheets (SDSs)

Employers must have an SDS for each hazardous chemical.
SDSs must be readily accessible to employees.
SDSs must be in English, but can also be in other languages.

Training

Employers must provide effective information and training on hazardous chemicals to employees at the time of their initial assignment, and whenever a new chemical hazard is introduced into their work area.
