HAZARD COMMUNICATION
Bradley JonesHazard Communication 29 CFR 1910.1200
HAZARD COMMUNICATIONHAZARD COMMUNICATION
OSHA created the Hazard Communication Standard to help ensure your safety when working with hazardous chemicals.
You have a RIGHT TO KNOW about the hazardous chemicals you use on the job and how to work safely with those chemicals.
HAZARD COMMUNICATIONHAZARD COMMUNICATION
What are hazardous chemicals,
What are material safety data sheets,
What is on product labels,
How hazardous chemicals affect the body,
What are the different types of hazardous chemicals,
How to protect yourself from hazardous chemicals.
Do I need a Hazcom Program?Do I need a Hazcom Program?
Do you:
• Sell
• Store
• Transport
• Use chemicals in your process
HAZARDOUS CHEMICALSHAZARDOUS CHEMICALS
“Hazardous chemical" means any chemical which is a physical hazard or a health hazard.
Most chemicals used in the industrial world can harm you in some way.

TYPES OF EXPOSURETYPES OF EXPOSURE
• Ingestion – swallowing the chemical
• Inhalation – breathing in the chemical
• Absorption – the chemical soaks through the skin
Types of Hazardous ChemicalsTypes of Hazardous Chemicals
Solids:• Powder• Dust• Fumes• Fibers
Liquids:• Mist• Concentrates• Mixtures
Gas:• Vapors
EXPOSURES LIMITSEXPOSURES LIMITS
Many chemicals have exposure limits, or allowable amounts of a chemical in the air.
These limits are often called “Permissible Exposure Limits”
They are based on 8-hour average exposure or ceiling or peak levels.
Levels must be kept below these limits for safety.
CARCINOGENSCARCINOGENS
Carcinogens are cancer-causing compounds.
Some chemicals are known human carcinogens, others are only suspected as carcinogens.
DOSH (California Division of OSH) has regulations covering the general use of carcinogens, and has specific regulations for several known human carcinogens.
CORROSIVESCORROSIVES
Sulfuric Acid
Ammonia
Chromic acid

Acetic Acid
Chlorine
FLAMMABLE LIQUIDSFLAMMABLE LIQUIDS
The vapor of a flammable liquid ignites and causes fire or explosion – not the liquid itself.
The flammability of a liquid depends on its physical properties:
• Vapor Pressure
• Flash Point
• Limits of Flammability
• Vapor Density
LABELINGLABELING
NFPA = National Fire Protection Association Blue = Health Red = Flammability Yellow = Reactivity White = Other hazards or special
handling
Scale: 0 (No Hazard) to 4 (Extreme Hazard)
NFPA 704NFPA 704
HMIS LabelingHMIS Labeling
The HMIS labeling system operates on the same principle as the NFPA diamond. • It also uses a numerical
system from 0-4 to indicate the severity of the hazard.
These labels should be used on individual containers of hazardous materials • Barrels, bottles, cans,
buckets, tubs, etc

PROTECTION FROM HAZARDSPROTECTION FROM HAZARDS
Engineering / job specific controls• Knowing what is in the product
your work with
• Using the smallest amount of a chemical to do the job
• Maintaining machinery and equipment to prevent leaks or releases
PROTECTION FROM HAZARDSPROTECTION FROM HAZARDS
Using available ventilation to reduce amounts of chemicals in the air
Keeping lids, doors or covers closed on chemical processes
Personal Protective EquipmentPersonal Protective Equipment
Dust masks and respirators
Glasses, goggles, and face shields
Hearing protection Gloves Foot protection Head protection Aprons or full-body suits
Administrative ControlsAdministrative Controls
Change the chemicals being used for less toxic substitutes
Rotating workers in shifts in hazardous areas
Separating work / eating areas to reduce exposure
Implementation of hand washing procedures
TrainingTraining
1910.1200 (h)
• Employers shall provide employees with effective information and training on hazardous chemicals in their work area at the time of their initial assignment, and whenever a new physical or health hazard the employees have not previously been trained about is introduced into their work area.
RecordkeepingRecordkeeping
1910.1020(d)(1)(i)(C) The medical records of employees who have worked for less than (1) year for the employer need not be retained beyond the term of employment if they are provided to the employee upon the termination of employment.
1910.1020(d)(1)(ii) "Employee exposure records." Each employee exposure record shall be preserved and maintained for at least thirty (30) years, except that:
RecordkeepingRecordkeeping
1910.1020(d)(1)(ii)(B) Material safety data sheets and paragraph (c)(5)(iv) records concerning the identity of a substance or agent need not be retained for any specified period as long as some record of the identity (chemical name if known) of the substance or agent, where it was used, and when it was used is retained for at least thirty (30) years
