During an extended power outage, such as the one caused by Tropical Storm Isaias, refrigerated and frozen foods may spoil. A great way to preserve your groceries that need to be kept cold or frozen is with dry ice.
Dry ice is very cold. -109 degrees F cold! It can help keep frozen foods frozen and refrigerated goods cold. Here are some guidelines from the U.S. Department of Agricutlure:
- Wear gloves when handling dry ice.
- Allow 2½ to 3 pounds of ice per cubic foot of freezer space. A 50-pound block of dry ice should keep food safe in a full 18-cubic-foot freezer for at least two days. More will be needed in upright freezers, and ice should be placed on each shelf. Your supplier may be able to cut blocks into slabs.
- If food from upright freezers can be tightly packed in coolers with dry ice, it may be easier to keep the food frozen for a longer period of time.
- If a freezer has a limited amount of food in it, pack the food compactly in coolers with dry ice.
- Fill a partly empty freezer with material like crumpled newspaper, clean bath towels or blankets to cut down on air circulation, which hastens dissipation of dry ice.
- Some suggest separating dry ice from direct contact with food packaging by placing boards or heavy cardboard between packages and ice. Ice may be wrapped in brown paper for longer storage.
- As dry ice dissipates, it becomes a gas. To avoid gas fumes, wait a few moments after opening the door of a chest freezer before bending over it. Stand back a bit when opening the door of an upright freezer.

AllGas is the premier manufacturer of dry ice in the area. Made to order in Monticello & New Hampton (Goshen) and in storage at our Newton location, we offer dry ice as 3/8″ pellets and 1/8″ rice.
Dry ice is made from solidified carbon dioxide (COs). Called “dry” because when it sublimates (goes from a solid to a gas) it doesn’t leave any moisture behind. That’s not the only difference between regular ice and dry ice. Dry ice is exceptionally cold – it sublimates at -109° F – that’s cold! It also lasts long which makes it the perfect “ice” for portable coolers.
Dry ice is used in a variety of commercial & residential applications. It is used in:
- Industrial dry ice blast cleaning
- Shipping frozen food & medical products
- Travel & camping refrigerators and coolers
- Special effects fog
- Power outages
- Science & school projects
A relatively new addition to our dry ice manufacturing is the rental of dry ice blasting equipment. Dry ice cleaning is like sand blasting except for no secondary waste. The dry ice evaporates leaving less clean up. It also is non-abrasive and non-toxic.
Dry ice cleaning/blasting is used in a diverse list of industries. From automotive to graffiti removal, it is the preferred method for high pressure cleaning.

Graffiti Removal with Dry Ice
Many building owners have struggled with how to remove graffiti, and often simply resort to painting over it. In the past, the only other option was to sand or soda blast the graffiti, but that can result in damage to the building as well as extensive clean-up. Many building owners, especially those owning historical buildings, have decided to turn to the use of dry ice blasting when removing graffiti. Dry ice blasting is time efficient and effective when removing graffiti from almost any surface, and it causes little to no harm to the existing building.
Benefits of Dry Ice Blasting for Graffiti Removal:
- One-Pass Cleaning – Unlike sand blasting & power washing, dry ice blasting only needs one sweep of the wand to clean the area. A real time and labor saver!
- No Clean-up – Dry ice sublimates, meaning it dissolves into a gas upon contact. All that is left is minimal paint clean up.
- No Odor & No Hazmat Issues – You are not using harsh chemical, so there is no smell. This means there’s also no harmful residue.
- Doesn’t Harm Structural Integrity – This is a relatively gentle process that can be used on a variety of architectural structures. Especially useful in removing graffiti from historical artifacts and brick.
Rent the equipment from AllGas and you could be in business today! Give us a call at 800-380-1427 for details.
Welding processes explained
Sometimes you happen across an article that explains something so well, there’s no point in trying to replicate it. We search each week for something to share on LinkedIn and Google. This week we hit the nail on the head with a Welding Champs blog post “9 Different Types of Welding Processes” by Jacob Mills. Welding Champs is a made up of a group of people who love welding. They have taken the time to put together a website of everything welding. It’s a great resource for people just starting out in welding as the articles and posts are well written and easily understood.
Here are the 9 differenty types of welding processes:
- TIG Welding
- Flux-Cored Arc Welding
- Stick (Shielded-Metal Arc Welding)
- MIG Welding
- Laswer Beam Welding
- Electron-Beam Welding
- Plasma Arc Welding
- Atomic Hydrogen Welding
Enjoy the whole blog post here. Remember, you can get all of your welding supplies and equipment at your nearest AllGas location.
- We continue to closely monitor the updates from the Centers for Disease Control (CDC), World Health Organization (WHO), state health departments and other experts. We have increased health and safety at every local office following best practices for preventative measures.
- We strongly encourage our customers to interact remotely via email or over the phone. Our customer service representatives will continue to be available over the phone. We recommend that you call before coming to any of our locations. The situation may dictate that we close our storefronts without notice.
- We recommend that our employees follow the Center for Disease Control (CDC) guidelines for disease prevention. These include cleaning your hands often with soap & water for at least 20 seconds or using hand sanitizer when available. We ask that our employees forgo customary handshakes and to keep a safe distance between themselves and others. Social distancing practices call for avoiding any unnecessary physical contact. Let’s say hello with a smile and not a handshake.
