WaterJet- Industrial Cleaning Conference- Safety

2011 Waterjet and Industrial-Municipal Cleaning Association


BLASTING, Pressure Washing.

The WJTA_ IMCA WaterJet Technology Association-Industrial & Municipal

Cleaning Association is holding their biannual conference and Expo of

September 19-21, 2011 at the George R Brown Convention Center in Houston


Plan to attend if you are cleaning anything from sewage, to parking lots,

to bridges, or cutting with water- at all pressures, or if you use

vaccuum trucks in your business.

There are workshops, boot camps, and live demonstrations as well as the

largest global exhibition for waterjet and water blast equipment.

If you are using waterblasters, pressure washers, or waterjetting

equipment, you should have on site

1. Recommended Practices for the US of High Pressure Waterjetting


-available in English and Spanish.

2. Video or cd- Waterjetting Equipment- 30 minutes

3. Medical alert cards for each person on site.

4. Recommended Practices for the Use of Industrial Vacuum Equipment

5. Video or cd- Vacuum Equipment.

Contact the Advisory Council if you would like a general Operations

Module. It contains the WJTA Video and “Recommended Practices,” some

suggested personnel safety policies that are specific to waterjetting

and not covered in current OSHA regulations, five laminated cards for

individual workers, and some suggested topics for in-house training

courses for your workers.

This Advisory Council module does not contain a self-help, self-testing

text. It is not a certification procedure. Pressure Washing and

Waterjetting are used in so many different applications that the general

training course would need to be customized for site specific projects.

Another Callie Houston book out, and other major developments.

Many of my readers know that I’ve been undergoing treatment for Cancer. Fewer seem to know that our second novel about Callie in Louisiana was published in February, also under the name L.C. Frenzel which is the pseudonym my husband, Charles Frenzel, and I use for our novels. Emerald Green is published in Kindle format, but you can read it with an emulator on any computer–in case you don’t have a Kindle. Our next Callie book, tentatively named Sweet and Sour, will be out in June and is set in Texas. The new book is much more ambitious and (we think) will deliver a lot more punch as Callie growing up entering the adult world.

My New Book is out on Amazon

Hi, people. My new book, a thriller written as a collaboration with my husband under the name of L.C. Frenzel, is out on Amazon in Kindle format. This book draws on characters you meet in shipyards and around the oil patch. Maybe you’ll enjoy a glimpse into the muddy workings of southern Louisianna. This book has a strong, young female main character…as you might have guessed. Find it at:


Cover Leaf:

In the pre-Katrina world of south Louisiana, a high school girl and her mother are caught up in a violent act of retribution.Callie Houston lives with her single-parent mom, Jeanne, in the small town of Hammond, La. She’s a smart, impulsive young woman who figures she can handle almost anything. Suddenly her world is turned upside down when her mother is kidnapped by Tony Ryan, one of her mother’s accounting business clients. The mobster is looking for papers incriminating him in an embezzlement scheme. Blood, pain, and violent death replace her sheltered world of books and nature.Callie’s story is not only about how she survives her ordeal, but also how painful choices are part of growing up.

Remember, you can read Kindle on your PC and Mac with the FREE app from Amazon.

Four-Way Test

We constantly feel the need to take action, but what action?
Every day, and in every direction, we can look around and see a lot of things that need to be done, many actions that need to be taken. A suffering child, a mother without means to protect her children, an impoverished man or woman on the street, teachers without adequate classrooms and students without books, working men and women without health insurance sitting in crowed hospital emergency rooms, elderly people without the warmth of a stove or the warmth of human caring– all this and so much more demands our attention. So many things in our immediate community, in our country, on our earth  urgently demand our action. The focus is on action, but what action. There must always be acts of choice which determine the paths we follow.
The FOUR-WAY-TEST is a set of rules that illuminates action, action that is supposed to be good and wise. One might say that the FOUR-WAY-TEST constitutes the rules that join action to wisdom. Wisdom’s first rule is seek the truth. I might say to you, alternatively, test for truth. Before you can act wisely, you must test the truth of the proposition that requires your action.
Is it true that the children for whom you collect christmas gifts need toys? Perhaps they urgently need food, or do they need shelter from violence in their community, even their own homes. And not only must you test for truth, you must follow wisdom’s second rule which is test for fairness. Action must lead to equity. Balance must be recognized. Is it fair to offer a scholarship without providing and following the rules of competition? To reward capriciously is to risk violating fairness. Equal opportunity is the  path of fairness.
So, we must test for fairness as well as truth. We need to know if the action will be fair to all concerned. And this leads to the third rule of wisdom which is test for benefit. Is there benefit to all concerned?  Moral benefit, economic benefit, cultural benefit?
We must not only test for truth and fairness, but who will benefit from the consequences of the action? What of fair selection, given equal opportunity? How far do concern and involvement reach if all who of those who are concerned are to benefit? The number of people who benefit theoretically from a school play production far exceeds the number of young people who can realistically try out for the school basketball team and benefit from participation in this sport. I enjoy sports, but one can point out that atheltics is by and large a vicarious experience. Life is not a vicarious experience. The test for benefit must consider whether or not the benefit is real or substitute.
And finally, the fourth rule of wisdom addresses the sense of community. Does the action lead to a common ground of being? Do we all feel part of the community after the action is complete. Have we practiced exclusive principles, or have we practiced inclusive principles.
Perhaps you recognize that what we are talking about is a lot like sportsmanlike conduct. Players of the Game are expected to agree on the rules, that is, agree to the truth; players expect to be treated fairly, that is, the rules are applied with equity; players expect to benefit from fair and honest competition according to their abilities; and players are on the same ground of being, that is ,they are all competitors in the same game. Too bad the pageants of our professional sports spectaculars aren’t good examples of exemplary human beings.
If this sounds like a complete guide to wisdom, let me remind you of what the Nazis believed to be true: it was fair that all Germans should benefit from being members of the community of the Master Race.
I think you will agree that there is another condition, another rule which we must apply; a fifth rule which must guide all of our considerations, one which we have to use before we can apply the FOUR-WAY-TEST successfully. We must exchange places with the other person. That is, we must be able to recognize their truth as our own, their fairness, their benefit, their sense of community. We must be able to do all of this without necessarily adopting their point of view.

That recognition of “other truth” is essential, also, in drafting a definition of “service above self”. I can’t imagine needing to say this to an audience of women. Women may not know all about the four way test of truth, fairness, benefit, and community, but they do know about service above self. Being a partner to the creation of new life out of one’s own material self is certainly service above self.

Perspectives on Shipyard Operations

It’s easy to believe that some industries run without rules and regulations. Shipyards have particularly difficult conditions to satisfy. In my experience, the shipyards I’ve been on are quite environmentally conscious, perhaps for a variety of reasons. Before rushing out to criticize anyone, read this document which will give you some perspective on a few problems in the maritime industry.

Thames River Project

The problem:

The Thames barrier was erected in 1989 to provide flood control to the upper reaches of the Thames River including the heavily populated areas of London. The gates could be raised from the riverbed into a vertical defense position in the event high surge tides threatened the London metropolitan area.

In October of 1997 a sand dredger, the Sand Kite, wrecked into one of the main gates of the Thames barrier. The ship was damaged and dumped its load of sand and aggregate, then sank onto the gate where it sat for several days atop its load. This caused paint failure and premature corrosion on the flat face of the gate. The failure of this gate could have had potentially disastrous effects on London, with flooding damage estimated at UK$21 Billion and extensive loss of life.

The UK’s Environment Agency had several requirements for the any repairs that were undertaken on the damaged gate. The barrier gate could not be taken out of service and had to be able to be closed at any time with a 1-hour notice to the cleaning contractor. In addition, there could be no environmental pollution or potential release into the environment during the surface preparation procedures. The twice-daily 21-foot tides and heavily traveled river created logistics problems for any repair to the gates. Because of these constraints any surface preparation that required stationary staging was rejected.

The solution:

The remotely controlled, vacuum attached JetTractm system provided by UHP Projects, Inc. was used to clean and prepare the surface of the gate for recoating. This system uses Ultra High Pressure (40,000 PSI) waterjets to strip the coatings from the surface. A patented seal allows the remote JetTractm crawler to attach itself to the gate using vacuum supplied by a remote vacuum skid. The paint and water is completely contained in a vacuum shroud and removed down a hose to a vacuum system located on a barge. The JetTractm crawler is remotely controlled and can move in any direction in both the horizontal and vertical positions as well as overhead.

How is this going to be spent?

A few days ago we decided that we needed to take some action on the new budget.

The government is going to need a lot of help if it is to know how to spend some of the following:

$6 Billion on energy efficiency in public housing.
$5 Billion on weatherization grants to homeowners.
$8 Billion on public transit and ancillary infrastructure.
$40 Billion assisting school districts to modernize.
$2 Billion rehabing foreclosed properties.
$29 Billion for roads and bridges.

Personally, I don’t think we should have very much faith in the decision process. We’ll tend to get storm windows on houses in Lake Charles, La. and screens on houses in Montana. New benches at bus stops will feature eye catching designs and no shelter roofs. Old-but-serviceable will become targets for new-and-novel. The public will get a whole slew of new buzz words and politicians won’t have to get colds kissing babies for a while. Dedicating a few new acres of asphalt is safer than repainting the food bank.

Inspection Manual for Flash Rust

Inspection Manual for Flash RustSupplement to Standard Photograph Guides
Supplement to VIS-4

Project Goals and Objective:

This document is a supplement to SSPC-VIS No. 4 NACE VIS 7 (or ISO 8501-4).

SSPC-VIS No. 4 NACE VIS 7, ISO 8501-4, International Paint Hydroblasting photos, and Hempel photos do not illustrate: 1. an example of lightly wiping; 2. an example of the surface after excess flash rust with loose rust dust has been mitigated by pressure washing.

For this manual, “Flash Rust” is the rust that occurs from the time the waterjet (WJ) or wet abrasive blast (WAB) cleaning process starts to the time the water used for the cleaning process dries. Flash rust often looks like a rust bloom.

Look at SSPC-VIS No. 4 NACE VIS 7, ISO 8501-4, and NACE No. 5- SSPC- SP-12 for a more detailed definition of flash rust.

“Rust-Back” is used in dry abrasive blast standards. Rust-Back occurs on surfaces that appear to be dry. Rust Back is the rust that occurs when DRY, bare steel is exposed to conditions of high humidity, moisture, or a corrosive atmosphere.

“Rust Bloom” is somewhat uniform rust spread evenly over a large section of the surface. Rust Bloom is a generic description. The observer doesn’t know if it originates from flash rust or rust-back.

Coatings manufacturers will designation the level of Flash Rust that is acceptable for the coating in a specific environment.

How much “Flash Rust” is formed is directly related to time of wetness. Engineering controls and project scheduling are key in reducing the time of wetness. Look at Blast and Dry, Clean Blasting, and Drying Effects.mpg

Inspecting for “Flash rust” is not rocket science.
It is deceptively simple or deceptively hard, because the decision is subjective.
? Prior to painting, look at the rust bloom on the steel.
? Find out the environmental history-if there was rain, pressure washing, waterjet cleaning, or no water involved at all.
? If there is no water involved, you reject the “Rust-Back.”
? If there is water involved in the surface cleaning, you place VIS-4 up to the surface nest to the rust and make an initial judgment concerning light, moderate, and heavy.
? If necessary, you wipe the “Flash Rust” to continue the determination between light, moderate, and heavy.
? Be consistent in the determination methods.
? Mitigate the flash rust to the amount required by the project specifications.

This manual does not address whether or not the amount of flash rust is suitable for coatings. Coatings manufacturers DO NOT recommend painting over HEAVY flash rust. The coatings must wet to the substrate, consolidate the dust, and be thick enough to cover the rust dust.

SSPC, NACE, ISO and Coatings Manufacturers published several guides to “Flash Rust” with photos.
All guides are to be used in the same manner. All lead to the same answer!
