The American Conference of Governmental Industrial Hygienists (ACGIH) is a professional association of industrial hygienists and practitioners of related professions, with headquarters in Cincinnati, Ohio. One of its goals is to advance worker protection by providing timely, objective, scientific information to occupational and environmental health professionals.

History [link]

The National Conference of Governmental Industrial Hygienists (NCGIH) convened on June 27, 1938, in Washington, D.C. NCGIH originally limited its full membership to two representatives from each governmental industrial hygiene agency. In 1946, the organization changed its name to the American Conference of Governmental Industrial Hygienists (ACGIH) and offered full membership to all industrial hygiene personnel within the agencies as well as to governmental industrial hygiene professionals in other countries. Today, membership is open to all practitioners in industrial hygiene, occupational health, environmental health, and safety domestically and abroad.

Presently, 11 ACGIH committees focus their energies on a range of topics: agricultural safety and health, air sampling instruments, bioaerosols, biological exposure indices, computer, industrial ventilation, infectious agents, international, small business, chemical substance TLVs, and physical agent TLVs.

TLVs and BEIs [link]

ACGIH establishes the Threshold Limit Values (TLVs) for chemical substances and physical agents and Biological Exposure Indices (BEIs).

Undoubtedly the best known of ACGIH's activities, the Threshold Limit Values for Chemical Substances (TLV-CS) Committee was established in 1941. This group was charged with investigating, recommending, and annually reviewing exposure limits for chemical substances. It became a standing committee in 1944. Two years later, the organization adopted its first list of 148 exposure limits, then referred to as Maximum Allowable Concentrations. The term "Threshold Limit Values (TLV)" was introduced in 1956. The first Documentation of the Threshold Limit Values was published in 1962. A new edition is now published every year. Today's list of TLVs includes over 600 chemical substances and physical agents, as well as over 30 Biological Exposure Indices for selected chemicals.

The TLVs and BEI are developed as guidelines to assist in the control of health hazards. These recommendations or guidelines are intended for use in the practice of industrial hygiene, to be interpreted and applied only by a person trained in this discipline.

In certain circumstances, individuals or organizations may wish to make use of these recommendations or guidelines if the use of TLVs and BEIs contributes to the overall improvement in worker protection.

My World

by: O.C.

Uh, yeah y'know, shit is wild he, heh
Can't complain though I'm alive
Healthy and all a that knahmsayin?
Just tryin' to do my thang, praise to all
Bust it that nigga Slick Rick said, I waited long time sweatin' it
I got jerked but now I'm gettin' it, hazy like asthma bizarre disaster
Stress almost held me down from bein' a master
The faster preacher, poet, a teacher, it's been so long like Monifah
Believe that I'm needed, in rappin', I breathe this
Some pick up a microphone and can't even achieve this
Oscar award winning your shit, I'm bored with it
Stop copy-catting son
(Why?)
'Cause your dog did it
Get your own lingo, make up your own jingle
Ten years later you be bitin' my single
Primo, take it downtown, swing it
Intervenin' on the board, sensimil steamin', yeah
Catch the vibe like a tribal dance
In the clubs on the low with the boy stance
Money rubbin' with a shorty got bumped by a chump
Tell him, step off, I'm doin' the hump, yeah
I say it's my world and I won't stop
And if you stand in my way you bound to get dropped
Some wish that I was gone 'cause they know I'ma win
In a minute, I'll be makin' six G's times ten
I'm the computer, printin' out data take notes
Then analyze the information and press send
Freaky like porno, Ron Jeremy saw no
Obstacle or pussy to stop him from bonin' a hoe
Me and the mic double trouble
Chicks look at us like twins, all lovable and huggable
Prognosis, on the, mic I choke out
Had the same effects from coughin', blowin' smoke out
Architect, rap technician, man listen
It's no doubt you gonna pump this in your system
My skills ill and all of that above
Confidence, I'm not worried 'bout a street buzz
I'm O.C., who you? I never heard of ya
Get out my face 'fore I turn into a motherfuckin' murderer
I want the green like indo, a mansion, a car
A wife who's never been a bimbo
Too much to ask, well, to me that's simple
Wanna retire on a yacht called the S. S. Minnow
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
Top choice, this here nigga got poise
Ain't a man alive who could stop my noise
I snatch a star from the sky, spark up your lye
You stand astounded wonderin' how I did it
Now you're star struck, like I truck gold
Treatin' me like a nigga havin' a million records sold
Now a star child, phenomenon like the X-Files
Rappers know I'm comin' so they go in exile
Czar in this rap shit, comin' on your mattress
Microphone fiend, I make beats do back flips
Fear me like genocide, serious
How I do it through your stereo, mysterious
O.C. do demolition, nil competition
Like robot Kong on a destroy mission
A matter of life and death you try to fight for breath
I snatch your heart from a slice through your chest
Who the best from New York to Bogota?
Who got face thinkin' they scare me with a scar, shit?
What I be bringin' is a terrible sight
A performance never again performed on the mic
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
