I’ve only heard from a few of you about the papers. I’m hoping everyone is set on their topics, questions, and concerns.  Please send an email if you have questions. I will be checking my email and this blog even while I’m on vacation. I promise, I’ll respond.

I’m working on exercises for Chapter 9 that will be interesting. I hope you’ve had an opportunity to read it.  Please take a few moments to read it over before our next class. 

Take Care,

Have a save Memorial Day Weekend.



Potential Topic: Chemical Safety Board

May 24, 2007

I just received this by email.  It could be an interesting topic for a paper on current topic!


The following message is from the U.S. Chemical Safety Board, Washington DC

In Testimony to House Workforce Protections Subcommittee, CSB Calls on
Governments at All Levels to Establish OSHA Programs for Public Employees

Washington, DC, May 24, 2007 – The U.S. Chemical Safety Board (CSB) today urged
‘governments at all levels to take steps to protect public employees from
preventable chemical accidents, including the establishment of programs
incorporating mandatory OSHA standards.’

In written testimony submitted today for a U.S. House of Representatives
subcommittee hearing, CSB Chairman Carolyn W. Merritt, speaking on behalf of the
five-member Board, said, ‘It is simply inequitable to afford public employees
with lesser workplace protections than workers in private industry.  No worker –
whether employed by the city, county, state, federal government, or the private
sector – should have to suffer injury or death just to earn a living.’

The hearing before the House Committee on Education and Labor Subcommittee on Workforce Protections, chaired by Rep. Lynn Woolsey
(California), was entitled ‘Workplace Safety: Why do Millions of Workers Remain
Without OSHA Coverage?’ The hearing will be web cast live from

The Board testimony cited the CSB’s investigation of a January 2006 methanol
fire and explosion at a Florida municipal wastewater treatment plant that killed
two public employees and seriously injured a third.  The final report and a
computer-animated safety video on the explosion at the Bethune Point Wastewater
Treatment Plant are available from the Board’s website,, under
‘Completed Investigations.’

The accident at the wastewater facility, which is owned and operated by the City
of Daytona Beach, occurred when city employees using a cutting torch to
dismantle a metal roof accidentally ignited vapors coming from the vent of a
nearby methanol storage tank.  Flames traveled back into the storage tank
through a corroded flame arrester, causing an internal explosion, multiple piping failures, and a large fire that engulfed the workers. 
In its investigation report, the CSB concluded that a lack of hazard
communication, inadequate safety training, and no control of hot work
contributed to the accident.

Chairman Merritt said, ‘This fatal accident that occurred in Florida should
serve as a cautionary tale for the twenty-five other states that do not provide
public employees with OSHA protections.’ This tragic accident, she added,
‘underscores the potentially grave dangers facing public employees who work with
dangerous chemicals without workplace safety standards.’

The CSB report noted that no Florida state laws or regulations exist to require
municipalities to implement safe work practices or communicate chemical hazards
to municipal employees.  Florida is one of 26 states that have not adopted plans
under the 1970 Occupational Safety and Health Act to provide OSHA coverage for
public employees.  Florida had a safety program for public workers but it was
discontinued in 2000, six years before the accident.

The CSB is an independent federal agency charged with investigating industrial
chemical accidents. The agency’s board members are appointed by the president
and confirmed by the Senate. CSB investigations look into all aspects of
chemical accidents, including physical causes such as equipment failure as well
as inadequacies in regulations, industry standards, and safety management

The Board does not issue citations or fines but does make safety recommendations
to plants, industry organizations, labor groups, and regulatory agencies such as
OSHA and EPA. Visit our website,

Week 2, 15/16 June 07

May 20, 2007

So, what’s coming up?  We’ll start the second week with a review of what we learned. Please start working on those papers,  they’re due next meeting.  If you have questions, please send an email or call me.    We’ll talk about the TLV odor thresholds, vapors, fumes and aerosols in greater detail.    We’ll introduce the idea of “What is a Hazard?”  and discuss Risk.  What is it?  How do I define it?  We’ll talk about a industrial hygiene walkdown.   Then, we’ll end the weekend with a discussion of some direct reading instruments and real brief discussion about ventilation systems. 

 Even as I write this, I have the mid-term study guide almost ready.  It will be posted right here.  Please feel free to comment on this site, leave comments and questions.  My goal is make this site a resource for you.

Week 1

May 19, 2007

It’s started! So what do you think? Good/ok/? One of my goals is to improve the course as it proceeds. Thanks for helping! I appreciate all the comments. I’ll continue to stay organized and provide the information to you as I have it. Week 2 will start with a quick review of where we’ve been. I’ll talk about AREC. (This acronym should be familiar now.) and TLVs. Then, we’re get into the next objectives.

As you work on the papers, please share them with me. I’d love to read them before next class meeting. If you don’t mind, I’ll provide comments. If you can’t decide on a topic, send an email, I’ll help. Just a reminder – next meeting is on 15 June 07, 6pm.
