New Executive Order Changes Face-Covering Requirements

By: Todd Mahon | Mission & Management | May 18, 2021

Image showing on the left an illustration of the face of a person wearing a mask. On the right is an illustration of a person flexing an arm with a bandaid on the inset of the state of Minnesota. In the middle is a question mark.

Things are changing fast. Last week, we published a blog post on the state’s three-step process to wind down many of the public health measures to respond to the COVID-19 pandemic. Within a matter of hours, the state announced major changes regarding the uses of face-coverings that made some of that information out-of-date. 

The big change happened with the Center for Disease Control (CDC) announcement. They adjusted their recommendations to advise that fully-vaccinated people do not need to wear face-coverings in many situations. 

So what are the changes and how do they affect historic sites and museums? The three-step process is largely intact with the obvious exception of what it had said about the mask mandate expiring when the vaccination rate reached 70% or on July 1, regardless of the vaccination rate.

According to Executive Order 21-23, face-covering requirements in most situations have been lifted. People who are not vaccinated are “strongly encouraged” to wear a face-covering until they are fully vaccinated. 

It’s important to know that the executive order does not prevent political subdivisions (like cities and counties) from placing restrictions within their jurisdictions that are more strict than the executive order. It also states that nothing prevents “businesses and other private entities… from implementing otherwise lawful policies or rules related to the conduct of their employees… or customers— including lawful face-covering requirements.”

In other words, be aware of what your local orders are and a museum can require face-coverings with its own policies. 

 

Important Changes in Minnesota COVID Guidelines Affect Museums

EDIT: Shortly after this post was publsihed the State of Minnesota issued updated guidelines and a new Executive Order. Check out the new blog post with updated information here

It’s been quite an experience for Minnesota’s local history community as executive orders have placed significant restrictions on businesses and nonprofits in order to combat the COVID-19 pandemic. In the first week of May, Governor Tim Walz announced more dialing back of the restrictions with a path towards the end of many requirements. 

Stay Safe MN announced a three-step plan to wind down the restrictions for indoor events and entertainment, which is how museums are classified in the state’s recommendations. 

Step One (Began on May 7)

  • Museums are required to have a COVID-19 Preparedness Plan.
  • Venues may open at 50% capacity, but must limit space between individual parties to six feet or more. 
  • Limits on outdoor activities with less than 500 people are lifted. 
  • Screening of employees is still required.

Step Two (Beginning May 28)

  • State requirements for physical distancing expire.
  • Face coverings are still required indoors and outdoors events larger than 500 people.
  • Screening of employees is still required.

Step Three (Beginning July 1 or when the statewide vaccination rate reaches 70%)

  • The indoor face covering mandate expires.
  • No additional information or clarification at this time if a COVID-19 Preparedness Plan will be required.
  • Cities, counties, school districts, and businesses may impose additional requirements. This may be expected to happen as the pandemic is not over with.

Radioactive Collections

By: Megan Narvey | Conservation | April 12, 2021

I recently had an interesting question sent to my inbox about the safety of uranium-containing glass in a museum collection.

“So, I read The Radium Girls and had watched that webinar on hazards in museum collections. Yep, I put two and two together and bought a black light flashlight. Snapped these pictures and wondered, is it safe to keep them on display or any precautions?”

Here was my response:

Great question, and love the black light photos! (As an extra safety precaution on top of everything else, I recommend wearing UV-protecting eyewear when using a blacklight – polycarbonate safety glasses are one good option). These objects are really cool and I bet people would love to learn more about them.

The only real way to know how much precaution to take with any radioactive artifact is to measure the radiation coming off it using a Geiger counter. You might be able to partner with local health & safety officials to test the radioactivity of the glass. I don’t know if you’ve used a Geiger counter before, but it’s totally non-invasive, non-destructive testing. 

Radiation is considered in “doses”, as in – how much radiation per year can I safely be exposed to? You can take one 'big' dose of radiation once per year and be safe, or you can get small exposures to radiation more frequently, and be at the same risk level. The risk is much less for a visitor who comes in occasionally and doesn’t spend all that much time near the radioactive glass compared to a collections worker who is working directly with these objects every day.

One way to mitigate risk is to limit the amount of time you spend with a radioactive object. Other ways to mitigate risk are to increase distance and barriers between you and the objects – good practice would be to always handle this glassware while wearing nitrile gloves; and to display it behind glass in a display case rather than on open display.

The good news is that the amount of uranium in glassware (or Fiestaware) is quite low – often as low as 0.5% of the weight of the object. They don’t emit much radiation. So it’s safe to have these kinds of objects in museum collections, although I recommend taking precautions like those I mentioned above.

National Register help: Property Evaluation Grant

By: Tamsin Himes | Funding | Preservation & Facilities | April 12, 2021

National Register help: Property Evaluation Grant

Listing in the National Register of Historic Places (National Register) is a prestigious designation that can have many benefits, including opening doors to funding opportunities for historic building preservation. The nomination is an involved process. We at the Minnesota Historical Society can help with pointers and funding to complete the documentation, but the process itself is carried out by the Minnesota State Historic Preservation Office (SHPO) and the National Parks Service (NPS). Before anything else, be sure to contact SHPO to fully understand the listing process.

Contact SHPO So, your organization has in its ownership a beautiful property that you believe has local/state/national significance and you want to find out how to apply to be listed on the National Register of Historic Places. Your first point of contact should be the State Historic Preservation Office. SHPO will give you all the information you need about the nomination process and how to get started. 

Eligibility: property evaluation SHPO will likely tell you, among other things, that a property evaluation should be completed to determine if the property is eligible for listing. This is where the Legacy Grant program comes in. There is a Structured Grant available specifically for property evaluation, which results in an official SHPO opinion on the eligibility of the property:  “This structured application provides funding to conduct an evaluation of a property for listing in the National Register of Historic Places. Properties listed in the National Register include districts, sites, buildings, structures, and objects that are significant in American history, architecture, archaeology, engineering, and culture.” (Grants Manual, p. 91) 

Grant Application Applicants can apply for this Structured Grant via the same platform as all other Legacy Grants. In order to be eligible for this grant your organization must fall under one of four categories: 1) nonprofit 501c3 organizations 2) units of state or local government 3) federally recognized tribal organizations, and 4) educational institutions. If your organization falls under one of these, then your next step is to visit this page for information about requesting an account on our grants portal. After being approved for an account, you will have access to the required paperwork and forms to begin the application process. 

When can I apply? The Property Evaluation Structured Grant is a small grant ($10,000 and under), so there are four opportunities a year to apply. Visit this page for deadline information. 

Who do I contact with questions? If you have questions about the National Register listing process, contact the SHPO here. If you have questions relating to grants and how MNHS can help you, contact the Grants Office at grants@mnhs.org or me at, tamsin.himes@mnhs.org

Create a username for your organization's Facebook Page

By: Joe Hoover | Information Technology | April 7, 2021
Change your Facebook name

Why should I create a username for my Facebook Page?

Your username (aka page URL) is the link or address for your Facebook page. It is what shows up beneath your page name and in the address bar of your internet browser. It is to help people find and remember your Page. Ideally it should be a name that clearly says who your organization is.

Reasons for choosing a @username.

  1. A well-formed @username allows people to search and find you and your organization easily without a lot of hunting around.
  2. Having a @username makes it really easy for people to tag you in their posts and link to your Facebook page. 
  3. Lastly having a good @username will help your organization rank better in searches.

Don’t ignore this step. Having an appropriate @username for your page can make the difference between people finding your organization or not.
You want people to easily be able to search for your organization and using an obvious, straightforward name is one of the best ways to do that.

What to avoid naming your page:

  • @acme1858History - A name like that looks more like a weak password since no one will know it or remember it.
  • @HistoryIsFun - While history may be fun no one will associate the name with your organization unless your organization's name actually is "History Is Fun"
  • @AcmeCoHisSo - You get nothing out of abbreviating this way. No Search engine can find it and no one will ever remember it. You would be better off writing out the full name of your organization.
  • @AcmeCountyHistoricalSocietyMN - This actually is a good name to avoid confusion if your organization's name is very common like "Washington" or "Jefferson", "Franklin" or "Jackson" the four most popular county names. But if your organization's name is "Kandiyohi County Historical Society" it is a very safe bet you don't need to add the suffix "MN" to your name.

How do I create a username for my Facebook Page?

1. Click Create Page @Username below your Page's name.

2. Enter a username, then click outside of the composer.
FYI: Creating upper and lower case letters in your name (also called camel case) will help visually with your name.
However, for Facebook accounts, upper or lower case in the URL does not matter. Someone typing in "AcmeCountyHistory" or "acmecountyhistory" both are recognized.

3. If the username is available, click Create Username and you're done!

Sustainable Museum Lighting

By: Megan Narvey | Conservation | March 2, 2021

Museums becoming more climate-friendly is increasingly important in the field, because the effects of climate change pose a huge threat to collections. It may seem counterintuitive to pair collections care with environmentalism, but when it comes to museum lighting they really go hand in hand. Almost every action you take to reduce energy consumption from lighting will also help you to preserve the light-sensitive items in your collection. On top of that, any action you take that results in lower electricity bills means more money you can spend on other aspects of collections care, like archival boxes and padded hangers!

I recently attended an interesting webinar about environmental sustainability and museum lighting presented by David Saunders and hosted by the Icon Environmental Sustainability Network. He said that although the biggest energy consumer in most museums is the HVAC system, museum lighting represents a sizable chunk of electricity use. In his talk, David Saunders broke down sustainable museum lighting into five actions. 

  1. Switch to LEDs
  2. Increased use of daylight
  3. Reduce light levels
  4. Shorter display times
  5. Better time management

From left to right: incandescent, fluorescent, and LED light bulbs. Photo by Megan Narvey.

Switch to LEDs

Switching to LEDs has an immediate impact on electricity consumption because they are by far the most energy efficient type of light bulb; in large part because they are so efficient at converting electricity into light rather than heat (cough cough incandescents). Because LEDs have a longer life than incandescent and fluorescent bulbs, there is also a reduction in the use of raw materials. 

LED lights emit little to no UV light, which is a huge benefit for the preservation of light-sensitive collections. So LEDs are a great lighting choice for many reasons: energy efficiency, lower long-term financial burden, less maintenance, and they’re better for collections. 
 

Increased use of daylight

This option might surprise many museum professionals! The argument here is that daylight is a free energy source, so it is completely environmentally friendly. The problem is that it’s difficult to control. The brightness, color, and direction of daylight varies depending on the time of day, the time of year, and clouds! 

Direct sunlight will quickly damage light sensitive objects, even with UV filtration. Therefore, you need control systems like shades, blinds, curtains or baffles; and you might need to change their position throughout the day. A really cool solution to this problem is the use of electrochromic glass (also known as “smart glass”), which darkens or clears automatically depending on the amount of sunlight hitting it. 
 

Reduce light levels

It’s important to limit the amount of light in museum display areas because light can damage many types of collection items. Lower light levels also benefit the environment! But there is only so much you can do to lower light levels before your collection becomes inaccessible because you can’t see it. It’s possible to create a space with very low light levels that is still functional - for example by featuring individual objects with spotlights. 

The use of dimmer switches is a simple way to increase your control over light levels. The sweet spot between preservation and visibility is 50 lux for highly light sensitive materials, and 200 lux for moderately light sensitive materials. Lux is a unit for measuring the amount of light in a square meter, and can be quantified using a light meter like this
 

Shorter display times

One way to achieve shorter display times that will benefit both the collection and the environment, without resulting in reduced access, is to use manual, timed or automated lights that respond to visitors. You can install proximity sensors that turn on the lights in an area when they sense movement, ensuring that the lights are off when nobody is in the room. Shorter display times can also be accomplished with an object case where the visitor presses a button to activate lights to view the contents for a set period of time.

Better time management

The final option can best be summed up by the old joke about dads running around the house turning off all the lights in unoccupied rooms. Ensuring that you turn the lights off in storage when you’re not working there, and turning the lights off when the museum is closed, can have a big impact.
