ice Arenas - Air Quality Rules

As of May 20, 2013, all ice arenas are subject to new air quality rules.  The rule changes are concerning air quality in the arenas, the measuring of that quality and employee training related to these measures.  The rules are applicable to all arenas, including those without internal combustion engine-powered equipment being operated indoors. 

Acceptable Air Quality
When the building is open to the public, the air quality conditions must be within the acceptable range and be maintained throughout the arena building.  This means that from the time the arenas doors open to the public to the time the doors close, the new air quality standards must be met.  This standard applies even when the arena is open with no attendance.  The acceptable air quality limits have been reduced to: one hour average concentrations of <20 ppm CO and <0.3 ppm NO2.

Certification and Training
All ice arenas must apply for certification annually.  You will receive an application and renewal notice from MDH (Minnesota Department of Health).  The new standard requires that at least one trained person must be available in the arena building when the arena is open to the public.   There must be annual refresher training specifically tailored to the facility and the trainee’s duties provided for all responsible persons. 

Measurement of Air Quality
Measurements of carbon monoxide (CO) and nitrogen dioxide (NO2) levels need to be taken at least twice per week when fuel-powered ice resurfacers are used.
  • One of the two sets of required measurements for resurfacers must be on Saturday or Sunday.
  • Air quality measurements must be taken at least once per week following maximum use of fuel-burning edgers.
  • If edging when arena is open to the public, testing is required 20 minutes after completion of edging.
  • If edging when arena is closed to the public, testing can be done any time prior to opening the building to the public.

Air Testing Equipment
Electronic air monitoring devices are permitted without special approval providing that they meet criteria stated in rule.
  • Air monitoring devices must be used, stored and calibrated according to manufacturer specifications.

When CO and/or NO2 Levels are High
When measurements of CO exceed 20 ppm or NO2 exceed 0.3 ppm, you must:
  • immediately increase the ventilation rate, and
  • suspend internal combustion engine
  • use until acceptable air quality conditions are measured throughout the building.

When unacceptable levels of CO or NO2 are measured, follow-up testing must be performed and documented as follows:
  • every 20 minutes until acceptable air quality is measured,
  • 20 minutes after the next five uses of ice maintenance equipment, and
  • at least once per day for the next three days.

Complacency is The Prelude to Disaster

There are many things that we do regularly and have done for years that become automatic. Driving is a prime example. We all drive to work or bring our kids to school driving the same route every day. Yet how many of us can recall every detail of that drive on any one occasion? Our minds are being occupied by the day to day minutia that creeps in to our thoughts on a regular basis. These are not trivial things but things that are important to our everyday life and family. What time was Billy’s or Suzie’s soccer game? What time was that meeting scheduled for at work? Whose birthday is it today?

When we embark on tasks that we have done over and over again those circuits or pathways in our conscience are not full and part of the task is being done by the unconscious part of our minds allowing space for other thoughts to creep in. This habituation and complacency is what can lead to injury not necessarily through carelessness but from tuning out what is going on merely from the fact that we have done it so often.

Every one of us, me included, have things that we say “I could do that in my sleep”. Repetition is what leads to complacency and habituation in many ways in the tasks we do, things we see, and safety shortcuts we might take due to inconvenience, lack of PPE, time crunches, etc. The habit of having done something one way, either correctly or not, for a period of time it becomes habituated in to our daily lives.

Some research done states it takes anywhere from 18 to 254 days to create a habit or to where doing a task becomes automatic. I would guess, that the frequency of the task being done would play in to the time it takes to reform the habit.

This plays to any of the tasks we do. Any task we do can benefit with retraining or revisiting the fundamentals in order to bring it back to the conscience part of our mind. Safety training can be at times repetitious and seem to be more of a bother than not but it is important in that it can bring things to light that have been pushed to the back to the dust bins of our mind and are overlooked due to compliancy and habit.

Safety training keeps us focused on what is important in the tasks we do on a daily basis. Many of the tasks we do can and are hazardous and complacency can lead to dire results, accidents and injuries.  Revisit the tasks that need to be done, think about their hazards, the safety precautions, procedures, and personal protective equipment that apply to those tasks and bring them back to the front of our minds. Remember Accidents cost money. Working safe is free.

Frozen Water Lines - Educate the Public

As a Public Works employee you know the value of preplanning for any job you do in the city.  One of the most important things you can do is educate your city residents before the cold weather hits.  Get something posted on your web site and/or printed for your utility bills to help people prepare.

In the midst of the 2014 cold wave I woke up to a frozen water pipe in my own downstairs bathroom.  For weeks I’d been blogging about, and keeping my eyes open, for news about frozen water lines.  On the day of our freeze up I just happened across a list of some very good tips. 

Of course the below grade bathroom had a vanity but if you recall the frost was 7-8 feet down in some parts of the state.  And the closed doors of the vanity, along with the contents of the vanity, kept the water pipe insulated from the warm air in the lower level.  Taking the contents out of the vanity, leaving the vanity doors open, using a space heater and applying heat tape slowly thawed the line. 

I've listed some tips that you may want to post on your city website.  If you include the space heater or heat tape options in your list of things residents can do to thaw their lines, I recommend running a link to precautions from the Consumer Product Safety Commission and Underwriters Laboratory – see below.  If the city suggests residents run a pencil-thin trickle of water make sure your city has discussed and determined what, if anything, will be done to adjust water bills or sanitary sewer flow – see previous blogs. 

By Cheryl Brennan

Your water lines may be at risk of freezing during prolonged periods of bitter cold if you had issues with frozen water lines last winter.  Here’s what you can do to prepare:
  • Monitor the weather reports for extended periods of severe cold; then take action.
  • Allow warm air to circulate in the area where the water comes in to the house.
  • Leave utility room doors open and clear space around the waterline.
  • Remove contents of vanity cupboards and leave the doors open.
  • If possible/practical leave snow cover over the area where your lateral water line runs from the curb stop to the house.
  • Put a fresh battery in the thermostat if the thermostat is not hard wired in to the home.
  • Run your cold water closest to the water line entry point for a couple minutes and then take the temperature of the water. 
    • If it is below 40 degrees Fahrenheit it is recommended that you let your cold water run from this faucet at a pencil thickness. 
    • You should run it non-stop when there is no one home, overnight when temperatures typically dip lower, or no water is being used for a period of time.
    • Notify the city/utility if this method is chosen.

If your water line freezes:
  • Use heat tape, a space heater (don’t leave it unattended) or a warm hair dryer on the pipe.  Follow all safety precautions recommended by Consumer Product Safety Commission   and  Underwriters Laboratory .
  • Watch for unintended consequences of sewer or septic backups if running water continuously.
  • If a contractor is needed to thaw the line be aware of unintended consequences of contractors thawing water lines, particularly if using an electrical welder. 
    • Namely fire, explosion, damage to appliances and electronics, and the possibility of damage to other property owners in the case of stray electrical current. 
    • Determine if the contractor is using a commercial device manufactured specifically to thaw frozen water lines.  
    • Determine if the contractor is insured. 

Sanitary sewer freeze up considerations:

Make sure the roof vent is not covered with snow or is otherwise blocked.  Snow build up over the vent will cause the sewer drain to slow down.  This prevents the warmer air in the sewer system from venting up the house line and keeping the line above freezing.

Frozen Water Lines....A "golden opportunity" to plan

On our last post we shared some information including sample policy language and a waiver on thawing frozen lateral lines.
 In the depths of the cold last year many cities felt pressured to make a decision on thawing lateral lines.  Some cities, and some contractors that a city might have recommended, used electric welders.  Some of the claims that came into the League specifically from using electric welders included:

* Fire damage to the home
* Damage to electrical appliances
* Stray current causing electrical equipment damage to neighboring properties
* A power surge that damaged radio systems equipment on the water tower
* Stray current that damaged phone lines

Here’s some comments from the head of the League of Minnesota Cities' property / casualty department.

Brian Pulczinski…… The P & C claims department received several frozen water/sewer line claims this past winter.  A city is obligated to exercise ordinary and reasonable care in the construction, maintenance and inspection of all utilities, including its water distribution system.  If the city fails to exercise ordinary and reasonable care in this area, OR if they respond to an occurrence inappropriately, the city could be found negligent and a third party may be able to recover damages. 

In the vast majority of these frozen water/sewer line cases, we found that most of the frozen lines were caused by an Act of God/Nature – unprecedented and unrelenting cold weather that caused frost to go deeper into the ground than ever before and deeper than the city could reasonably have anticipated occurring.  Generally speaking, the city is not negligent in these situations and not responsible for damages to a third party.  For the few cases we found negligence, most of these involved some type of action the city took when responding to the frozen lines (i.e. – using a welder to thaw out a frozen water line, causing a fire at a residence home).  

Here in the Loss Control department at the League we’ve identified two pieces of equipment that are specifically marketed to thaw frozen lines if your city/entity makes the decision to attempt to thaw frozen laterals (see previous post for some guidelines).  The “Hot Shot” The Hot Shot  distributed by General Pipe Cleaners and The Magikist Pulse De-icer.

Last year retailers ran out of equipment to sell due to the heavy demand across a wide section of the country.  Now is the time to make purchases and/or make arrangements with neighboring cities to share this equipment. Keeping in mind that it is just as cold for people in the neighboring city as it is in your own!  For that reason it is important to make note of where there were freeze ups in the past.   

Next up we’ll talk about some helpful hints to post on your city web page.

Frozen Water Lines....... Take 2 ???

Last winter brought unprecedented cold deep into the mid-west causing water line, sewer line and water tower freeze ups.  While the trees are still a blaze of red, orange and gold now is the time to consider some “golden rules” about informing your residents and business owners on what they can do to lower the possibility of a freeze up in their lateral water lines. 

It’s also a good time for policy makers to contemplate what another hard winter might bring.  In the next 3 blogs I’ll share comments from our Property/Casualty Claims department and the head of the League’s Research department.  I’ll share a sample waiver and ordinance for water line thawing from our Loss Control Risk Management Attorney and provide links to a couple equipment resources with which we at the League are familiar. 

Now is the time for policy makers and department heads to make some decisions about how the city will address such things as letting water run to prevent freeze ups, or having city employees thaw lateral lines.  Here are some considerations from the head of the League of Minnesota Cities’ Research department.

Jeanette Behr….
Reducing utility bills due to constantly running water:
If your city is again faced with residents having frozen water lines and asks residents to run water, please consider adopting a policy before reducing utility bills. Decisions made pursuant to a policy protect the city. Tax dollars must only be spent for public purposes. In theory, if a city asks some residents to run water to protect city infrastructure, the city may be able to reduce the charges accordingly and still meet the legal test that tax dollars be spent for a public purpose even if there is some private benefit to the individual resident.

Consider noting in the policy and council meeting minutes that running water in residences or businesses in certain parts of the city protects city infrastructure from expensive freezing and breaking. (It's best to target those areas of the city that have a history of freezing lines to limit the amount of water and tax dollars used.)

As a counterargument, many cities do not reduce utility bills for residents. Last winter, many cities chose this approach.  Still, these cities provided helpful information on city websites about ways residents could prevent frozen water lines and noted that the cost to run a small amount of water is much lower than paying to thaw out frozen lines

Thawing resident's lines (lateral lines)
The same questions come up if a city is thawing lines that are a customer's responsibility. (Let’s call these lateral lines.) If a city council decides to provide line thawing services, again, consider adopting a policy.  (See sample waiver and policy below.)

For example, if it's hard for your city to identify where lines are freezing, it may justify using tax dollars to help residents thaw out their lines. Document these concerns in meeting minutes and provide some evidence of frozen city water mainlines resulting from lateral line freeze ups if you can. 

Also, if the city is looking at multiple frozen lines in numerous houses there may be a general health, safety, welfare concern in having so many residents without drinkable water. It's best to work with the city attorney and get a written waiver from the property owner if your council feels it's necessary to send public workers onto private property to thaw frozen lateral lines.

Next up we’ll discuss claims caused last winter due to the use of electric welders.

(Frozen Water Laterals)


I, ____________________________________ (“Owner), am the owner of the residence located at _________________________________________ (Property Address),  ___________(City)  Minnesota (the “Property”).

As a result of cold weather conditions, the lateral water lines (the “Lines”) located on the Property have frozen.  I have requested the City of __________________________________(the “City”) for help in thawing the Lines.  I understand that the repair or thawing of the Lines is NOT the responsibility or obligation of the City of ______________________________________(the “City”).    I have, however, requested help from the City to thaw the Lines.  THE PURPOSE OF THIS WAIVER OF LIABILITY AND HOLD HARMLESS AGREEMENT IS TO ASSURE THE CITY THAT IT WILL NOT BE HELD RESPONSIBLE FOR ANY DAMAGE, DIRECT OR INDIRECT, THAT I, THE PROPERTY OR ITS CONTENTS MAY INCUR, NOW OR IN THE FUTURE AS A RESULT OF THE WORK THE CITY PERFORMS ON THE PROPERTY IN THE COURSE OF ATTEMPTING TO THAW THE LINES.

I ACKNOWLEDGE that the process or procedure to be used by the City to attempt to thaw the lines, which may include the use of_________________________(name of equipment used), involves risk of damage to the Property, and that the City does not assure me or make any representations to me that damage will not occur to the Property or its contents as a result of the process or procedure used to attempt to thaw the lines.  The risks involved in the process or procedures that the City may use to attempt to thaw the lines include, but are not limited to, fire losses and claims for damage of any kind to buildings, appliances, electronics, etc.  I hereby represent that I am willing to accept all such risks, and to protect the City from such claims that may be made by me or others.

 I FURTHER ACKNOWLEDGE that the City will not assist in the thawing of the Lines unless this WAIVER OF LIABILITY AND HOLD HARMLESS AGREEMENT is signed by me and delivered to the City prior to the City performing any such work on the Property. 

IN CONSIDERATION for help from the City to thaw the lines on the Property, I agree as follows:

I HEREBY RELEASE the City, it’s employees, officials and agents from any and all claims for damages that I or the Property or its contents may sustain or incur now or in the future as a direct or indirect result of the City’s attempt to thaw the lines, and I hereby waive any right of claim I may have, now or in the future, against the City, its employees, officials and agents as a result of any such damage that may result from that attempt.

I AGREE that neither I nor any other owner of the Property or its contents will make a claim, sue, or otherwise assert rights against the City, its employees, officials or agents for damages claimed to have resulted from the City’s attempt to thaw the lines.

I AGREE TO DEFEND AND HOLD HARMLESS the City, its employees, officials and agents from all claims, suits, judgments, damages, losses and expenses, including reasonable legal fees and costs arising in whole or in part from the work performed by the City in its attempt to thaw the lines. This waiver of liability does not waive liability for any injuries that I obtain as the result of willful, wanton or intentional misconduct by the City or any person acting on behalf of the City.



SIGNATURE OF OWNER:_____________________________________ Date of Signature ______



Sample Policy Statement


1. The City will provide a service of thawing frozen service laterals to owner occupied residences, owner-occupied residential condominiums and owner-occupied co-operative housing. Except as outlined elsewhere in this Policy for City-owned rental or non-profit housing, the City will not provide a thawing service for any other class of property.

 2. The City will thaw external water service laterals only, not frozen plumbing inside the residence.

 3. The City will respond to calls in order of complaints received.

4. Calls received during regular working hours shall be responded to as resources permit. Calls received after regular working hours will be responded to within sixteen hours of receipt of the call, or as soon as possible after sixteen hours of receipt of the call in the event that other emergencies tie up resources and make it impossible to deal with the thawing request.

5. If a crew is already out on overtime basis when a request to thaw a service lateral is received, the crew will respond prior to going home, unless it is likely that the work will keep the crew out past midnight.

6. There will be no charge to the resident if the property can be thawed without digging, and if it is the first occurrence of the season for the property. A charge of a fee as set by Council, payable in advance, will be made for subsequent thawing services within a single season.

7. City-owned rental or non-profit housing units will be afforded the same thawing service as ‘owner occupied residences’, except that the Department of Building and Property Management will be charged for the full cost of the service. The Department of Building and Property Management are free to employ the services of an outside contractor, if they view the wait is too long for their tenants.

8. [OPTIONAL] The City will use hot water or steam in its thawing operations. The use of electric pipe thawing machines or welding machines is strictly prohibited, and persons using same will be held liable for any damage caused

9. The City reserves the right to deviate from this policy at any time if deemed to be in the best interests of the City and its residents based on safety, political and economic considerations.  Any deviation and the reason for the deviation shall be documented in writing.
