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.

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
![Page 12: HAZARD COMMUNICATION](https://reader036.fdocuments.in/reader036/viewer/2022062315/5681538b550346895dc18d93/html5/thumbnails/12.jpg)

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.
![Page 14: HAZARD COMMUNICATION](https://reader036.fdocuments.in/reader036/viewer/2022062315/5681538b550346895dc18d93/html5/thumbnails/14.jpg)
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.

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

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
