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

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

Lye

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
