What will they think of next?

Sometimes you just have to stand back and see the humor in a situation.  Laugh a little and then go talk to someone about the dangers.  In this case, the GC asked the electrical contractor to provide the main panel and some GFCI outlets early in the job (that’s good).  The concrete guys hadn’t gotten there yet, but were on their way (that’s typical).  What to do with the panel box set on the ground already wired and running the temporary lights?  Here is one solution – not so typical.

After checking out the unusual suspension system, I found that there was no strain on the actual wiring although the height of the service entrance cable and its installation needed to be improved.  The ladder access to reach the main breaker might be a little short but that depended upon who was using the ladder.  Framing and other construction exposures were going to be a little tricky around this whole installation.

The pad got laid and cured, the electricians came back and reset the panel, the superintendent was asked not to be so creative next time, and I got a funny picture.

Ban the Wire!

While teaching electrical safety in our OSHA 10/30 classes I like to throw out the question “Who thinks putting metal and potentially exposed electrical together is a good idea?”  On all worksites I’ve seen a slow evolution to the use of nonconductive tools and equipment.  For example, the replacement of metal ladders for fiberglass, the repair of extension cords with molded plastic replacement plugs, the use of plastic cages on temporary light strings instead of metal guards.  All good, but in today’s photo we have short lengths of wire being used to hang the sting lights.

Is this a problem?  The string lights are from a reputable manufacturer.  Built-in molded plastic hanger eyes are provided.  But, check the manufacturers’ literature- the plastic hanger eye is provided for use with “messenger cable or hooks.”    Messenger cable???  Why bother with that when we can just hang the lamps using some bits of wire?

Look closely – this is not a usual case – the lamp assembly is pulled over and tied off to a metal stud with a spare length of wire pointing into the aisle, ready to catch a worker or hit the bulb. Then there is a small twist of wire being used to lock the clam shell type cage.  Why is wire being used when plastic zip ties and bits of string are readily available in the workplace?

The installation shown above might pass OSHA inspection since the wire is passing through the manufacturer’s establish plastic eye (reference OSHA 1926.405(a)(2)(ii)(F) Temporary lights shall not be suspended by their electric cords unless cords and light are designed for this means of suspension).

My suggestions – stop arguing about OSHA compliance.  Instead, fool proof everyone’s safety by setting up a worksite rule that says “ NO wires” when setting up temporary lighting or extension cords,  that keeps everyone from making a random mistake that could lead to electrical shock.

What We Learned This Year – VOSH Wrap-up

Friday, June 12th, 2009

The VOSH Conference is at the very top of Circle Safety’s list of favorite meetings to attend.  Yes, we are there as exhibitors and as presenters of

educational sessions – Jan presented on Electrical Safety and Anna spoke on OSHA Recordkeeping Issues – but we are also attendees at the break-out sessions.  Each year our consultants who attend the conference select sessions that build our individual and corporate knowledge base.  We ask questions, take notes,
collect handouts and business cards, and share what we learn with each other.

Here are only a few of our notes:

New Dust Mask Demonstration – Reed Schaffer with 3M Corporation demonstrated newer dust mask and respirator technologies that are on the market protecting workers.  He stressed the importance of evaluation selection criteria – knowing the contaminants and their concentrations is key in choosing an appropriate respirator; i.e., exposure limits, odor thresholds, IDLH limits, and particulate molecular weight.  Correct donning of even the simplest respirator protection still remains a key point for employee training and management follow-up.

 Leading & Lagging Indicators – Dave Mazary from Western Yorktown Refinery clearly showed that setting “OSHA compliance” as the goal leads to a minimal effort, comparable to a  C- grade.  Relating this grade to performance in school, we would hope that most managers would strive for a higher grade.  This can be accomplished by incorporating industry best-practice as a supplement to OSHA rules and by helping  workers reach peak safety performance through clearly defined tasks & objectives;  training the workers to properly perform these tasks; measuring the performance with validity; and rewarding for desired performance – immediately, personally and sincerely.

Crane Maintenance – Bill Davis with Zurich provided excellent photographs and a fast-paced discussion of the leading causes of crane accidents with highlights on crane maintenance and correct set-up and operation as preventions.  Q&A time highlighted areas of improvement in the new OSHA crane standard (to come out in Fall 2009?).  The proposed standard is supposed to include a 20-foot “limited approach” prohibition for overhead power lines – a 10-foot improvement on what we have now.

As we wrap up this year’s conference, we look forward to what VOSH has planned for the coming year, and as always, we anticipate interesting topics and new learning opportunities.

Comparison Shopping for Safety

Friday, May 29th, 2009
Buyer’s Guide above the extension cords in the electrical aisle at hardware store.

Buyer’s Guide above the extension cords in the electrical aisle at hardware store.

Part of what we do at Circle Safety is “mentor” people who have been designated as Safety Coordinator by their employer.

Recently I’ve started taking my clients to Lowes or Home Depot for a session on comparative safety shopping.  As we walk the aisles, I show them how to determine whether products meet two basic, important tests – OSHA compliance and best-practice. 

Consider that extension cord you want to buy.  If you have never researched the origins of OSHA standards on flexible cords and cables or dissected the meaning of “hard use” as applied to ratings then you may not make the best selection.  This is usually the case for most employees who are asked to order equipment or to go to the hardware store and pick up a new cord. 

As any good comparative shopper knows, you have to research and read labels.  And labels can be very deceptive.  I find this to be case with extension cord packaging/labeling.  That’s why I’m very grateful that the Home Depot and Lowes both have large instructional signs over their extension cord shelves.  So, yes, it’s getting easier to select the right extension cord but this isn’t the case for other electrical items typically seen in the workplace.

What about GFCIs, temporary lights or replacement plugs/ends for extension cords?  There is much confusion (some due to the OSHA standards), and a lot of outright deception in packaging. 

I’ve now introduced a hands-on workshop in our OSHA 10/30 hour training classes which gives attendees a chance to examine the boxes and attached labeling on commonly-used electrical products.  Those attending my Electrical Safety: Common and Not So Common Issues sessions at the 14th Annual Virginia Occupational Safety & Health Conference 2009 will get a chance to participate in comparison shopping for safety.
