“Hazardous communication RIGHT TO KNOW” Program

is abreviated as “HAZCOM”

This program is not intended to tell you how to do your jobs.

It is not a technical chemical safety course.

It’ simply Hazard Communication

05/03/23 DSHE4

Why do you need to know this information?

The 29 CFR 1910.1200 says:

Everyone working with/around Hazardous materials has the right

And the Responsibility to be aware of the hazards and proper safe

Work procedures for hazardous materials used or produced in their

work area.

The primary objective is for you to know how and where to find specific hazard information.

DefinitionsAcids – A corrosive chemical that proteinizes upon contact with body tissue

and causes immediate pain.

Bases – A corrosive chemical that does not proteinize upon contact with body

tissue and does not cause Immediate pain.

Carcinogens - Substances which under favorable conditions through direct or

indirect action, either externally or internally, act on healthy

cells to cause a metamorphosis and bring about a rapid

proliferation of cellular elements and the development of

structure abnormalities.

Chemical – Means any element, chemical compound or mixture of elements

and/or compounds

05/03/23 DSHE44

Compressed Gas – Non Flammable materials which have a PSIA greater

than 40 at 70*F, or a PSIA greater than 104 at

104*F, or those Flammable materials which have a

PSIA greater than 40 at 100*F.

Those with sufficiently high toxicity are class “A” poisons and receive a

Poison gas label.

All flammable gas,liquefied or non-liquefied and dissolved have flash points below room temperature. It’s impossible to avoid forming a flammable mixture if any leaks into the air.

Container – Means any bag, barrel, bottle, box, can, cylinder, drum

Reaction vessel, storage tank or the like that contains

hazardous chemical.

05/03/23 DSHE45

For purpose of this section, pipes or piping systems are not considered as containers.Corrosive – Any chemical or substance that by direct chemical action is injurious

to body tissue or erodes metal.

Employee – Means a worker employed by an employer who may be exposed to

hazardous chemicals under normal operating conditions or

foreseeable emergencies, including, but not limited to, production

workers, line supervisors, and repair or maintenance personnel.

Office workers, grounds maintenance and security personnel or non

resident management are generally not included. Unless their job

performance routinely involves potential exposure to hazardous

chemicals.

05/03/23 DSHE46

Explosive – Substances under which certain conditions of shock, temperature

or chemical reaction decompose with violent rapidity, usually

releasing large quantities of gasses and heat.

Exposure/Exposed – Contact with a hazardous chemical in the course of

employment through any route of entry (inhalation,

ingestion, skin contact or absorption, etc.) and includes

potential (e. g., accidental or possible) exposure.

Flammable Liquids – A liquid whose vapor can form an ignitable mixture with

air. The liquid is the fuel, the surrounding atmosphere is the

oxidizer. For the mixture to burn an ignition source must be

present.

05/03/23 DSHE47

Foreseeable Emergency – Any potential occurrence such as, but not limited to,

equipment failure, rupture of containers, or failure of

control equipment which could result in an uncontrolled

release of a hazardous chemical into the workplace.

Hazard warning – Any words, pictures, symbols, or combination thereof

appearing on a label or other appropriate form of warning

which convey the hazards of the chemical(s) in the container(s).

Hazardous Chemical – Any chemical which is a physical or health hazard.

05/03/23 DSHE48

Health hazard – Means a chemical for which there is a statistically significant

evidence on at least one study conducted in accordance with

established scientific principles that acute or chronic health effect

may occur in exposed employees. The term “health Hazard”

includes chemicals which are carcinogens, toxic or highly toxic

agents, reproductive toxins, irritants, corrosives, sensitizes,

hepatotoxins, nephrotoxins, neurotoxins, agents which act on the

hematopoietic system, and agents which damage the lungs, skin,

eyes or mucous membranes

05/03/23 DSHE49

Identity – Means any chemical or common name which is indicated on the

material safety data sheet (MSDS) for the chemical. The identity used

shall permit cross-references to be made among the required list of

hazardous chemicals, the label and the MSDS.

Label – Means any written, printed or graphic material displayed on or affixed

to containers of hazardous chemicals.

Material Safety Data Sheets (MSDS) –- Means written or printed material from

manufacture prepared in accordance with the OSHA 29 CFR

1910.1200. Standard.

05/03/23 DSHE50

Oxidizer/Reactive – Any chemical That increases the burning rate of material

by readily yielding oxygen or other oxidizing gas; or

enters into a violent reaction during which the

spontaneous liberations of heat/gas is too rapid to be safely

dissipated.

Physical hazard – A chemical for which there is scientifically valid evidence to

show that it is combustible, (such as a compressed gas),

explosive, flammable, an organic peroxide, oxidizer, pyrohoric,

unstable (reactive) or water reactive.

Radioactive – Having the property of emitting particles or radiation from an

atomic nucleus such as alpha, beta or gamma rays, as it is the

case with uranium, radium, thorium, etc.

05/03/23 DSHE51

Toxic – Any chemical which when ingested, inhaled, absorbed,

applied to, injected into or developed within the body

in relatively small amounts, may cause damage to structure

and otherwise disturb the body’s functions.
