Dry Ice Summer Time Safety

Buy dry ice Scoop of dry ice

Summer is here and that means so is the heat – lucky for you, Cee Kay Supply has Dry Ice to support all your summer fun. However, with most things in life, Dry Ice does present its own risks. This article will help educate you on how to properly handle all your solidified CO2 to ensure a safe and fun season!

So, obviously dry ice is cold – but just how cold? A normal ice cube you may toss into your favorite beverage melts at 32 degrees Fahrenheit; Dry Ice sublimates, which is the transition from a solid phase to a gaseous phase while skipping the liquid phase, at -109.3 degrees Fahrenheit! This extremely low temperature is enough to freeze your cells with prolonged contact, causing injuries very similar to that of a burn. Typically, minor burns can be treated with some over the counter antibiotic ointment and a band-aid. However, if skin blisters appear – see a doctor.

Now we know just how cold this product is and what can happen with prolonged skin exposure, but how do we handle this product safely? You should always wear hand protection when transporting Dry Ice. Cloth or leather gloves are preferable, but even an oven mitt or towel will get the job done. It is a good idea to think about eye protection as well – your eyes are extremely sensitive and exposure to Dry Ice can cause serious damage. Consider throwing on a pair of safety glasses to protect your vision.

Next, we need to discuss proper storage. Dry Ice can last several days if stored properly – but there are a few key points to note. You always want to store your product in a well-insulated container, the thicker the better for longevity. The most important thing to keep in mind is that you do not store your ice in a completely airtight container. As the Dry Ice begins to sublimate, the gaseous product will begin to increase the pressure in your container and can lead to the destruction of your container, or even an explosion. For small quantities of Dry Ice, Styrofoam coolers are a great option. For larger quantities, consider purchasing a commercial grade storage container that is meant for the specific purpose.

Last but certainly not least, store your ice in a well-ventilated area. Carbon Dioxide is present in our normal breathing air at 0.035%, if this number gets to 0.5% – it can be problematic for our health. Too much C02 exposure can lead to dizziness, fatigue, headaches or even asphyxiation. But do not fret, increase your ventilation by opening doors and windows and turning on fans. Keep in mind, C02 in a gaseous state will always settle to the ground as it is denser than air.

Now that you have a little more knowledge on this widely used product – have a safe and fun summer. Get outside, stay cool and enjoy the weather! For any questions, you may always reach out to myself at edownes@ceekay.com.

Paint and Coating Stripping with Dry Ice Blasting + Abrasive

We often get asked the question, “Can dry ice blasting remove paint?”  This can be a tricky question as the answer is specific to the situation (type of paint, type of surface, how well is the paint adhered, etc.).

Dry ice is a gentle medium and in some applications it is not successful at removing paint with just dry ice alone.  Depending on the type of paint and primer, even aggressive dry ice blasting can be too slow or too gentle.

Sandblasting

Traditional methods for removing paint and other types of surface contaminants, such as corrosion and paint, are effective but have negative side effects that can become costly and add time to projects.  Sandblasting and other types of media blasting create a significant amount of waste and respirable and environmental dust.  Not only does this require extensive cleanup and containment setup, but it is also unhealthy for workers performing the job.  These methods leave residue and moisture on the surface being cleaned, which requires a second wash and drying time before re-painting or re-coating can begin.

Adding an abrasive to dry ice blasting boosts its’ aggression and effectively removes paint and coatings, while eliminating the issues with traditional methods of removal.

Why dry ice + an abrasive?

When you’re cleaning and preparing a surface, you want to be sure you can remove 100% of the surface contaminants and old paint/coating before applying a new coat – and you want to do so as quickly and efficiently as possible.

Dry ice blasting + an abrasive:

  • Significantly reduces waste and dust generated by traditional methods
  • Does not leave residual media on the surface being cleaned
  • Does not require drying time (no water used in cleaning process)
  • Provides a more environmentally friendly and worker safe cleaning method

Benefits of dry ice + an abrasive

Coating and corrosion removal (1)

1) Eliminates pre- and post-cleaning processes
With the need for containment setup and waste cleanup, methods such as sand, vapor, or slurry blasting are time-consuming and labor-intensive. These methods create a tremendous amount of secondary waste, which means containment must be setup before cleaning begins and when the cleaning ends the secondary waste must be collected and disposed of.In the case of a stripping coating and corrosion from a tank with slurry blasting, containment is setup for water runoff and other waste, which adds time and resources to the project.  When the stripping process is complete, workers must wait for the surface to completely dry before applying a new coat.

Additionally, in saltwater environments soluble solids and chloride accumulates on surfaces, which results in an added pre-wash step that must first be removed before the stripping even begins.

Dry ice + an abrasive limits the amount of time and resources needed for a project by eliminating the need for containment, waste cleanup, drying time, and any post-wash steps. This leads to a considerable amount of hours saved per project.

Also, in the case of saltwater environments, the cleaning can be completed in one step.  Dry ice + an abrasive eliminates pre-washing because the media removes soluble solids and chlorides simultaneously while stripping the paint from the surface.

 

2) Reduces dust levels and waste
As most people know – sandblasting and other traditional types of media blasting generate significant dust and waste. Respirable dust is harmful to the operator, surrounding workforce, the public, and the environment. OSHA has strengthened its standards to encourage initiatives that limit dust exposure. This is one of the reasons for the excessive containment setup required before cleaning with garnet, crushed glass, coal slag, and other blasting methods.

Wet blasting, such as slurry blasting and vapor blasting, uses water with an abrasive to capture dust molecules and keep them from going airborne. While this is effective at reducing dust levels, the method still creates a considerable amount of waste. As well, water as a medium slows down the abrasive particle velocity, which thereby, limits productivity.

Dry ice blasting mixed with an abrasive seeks the best of both worlds. As the dry ice impacts the surface and sublimates from a solid to a gas, that gas suppresses the dust from going airborne due to the fact CO2 gas is heavier than air.

The reduced dust levels also leads to increased operator visibility, which makes it easier for the operator to effectively clean.

 

3) Safer for employees and the environment – Meet OSHA guidelines

Coating and corrosion removal_2

A 97% reduction in dust levels means that the operators and surrounding workforce are not exposed to unhealthy levels of respirable and nuisance dust.  Dry ice + abrasive easily meets OSHA guidelines for dust levels.

Dry ice + abrasive is also a more environmentally friendly option compared to alternatives.  The solution requires significantly less media input than alternative paint and corrosion stripping solutions.  The Cold Jet dry ice + abrasive solution uses 100-150 pounds of media per hour, as opposed to 600 pounds or more per hour from traditional options.  This means that less media and dust is being dispersed into the surround environment.

 

4) Extensive time and costs savings
The dry ice + abrasive mixture eliminates the need for pre- and post-washing, containment setup, and waste collection.  It also cleans faster than many wet abrasive options. This results in a major reduction in project time.

The solution also leaves the surface completely dry and free of residue, which eliminates hours of drying time and allows you to apply a new coat of paint or coating immediately following the cleaning process.

 

When should you use dry ice + abrasive?

1) Heavy or pitted corrosion
coating and corrosion removal 3

If the corrosion is pitted in the metal, dry ice alone won’t be enough to remove that corrosion for proper coating adhesion. With dry ice + abrasive, you can meet requirements for a surface standard prior to the new coating. It will give you a near white metal finish by removing a small layer of the metal and exposing a new metal surface profile.

This is a major advancement for dry ice technology since dry ice blasting has always been non-profile, but by adding an abrasive you can create a profile of 1-5 mL.

2) If dry ice blasting alone just isn’t working
Certain types of paint, corrosion, or coatings simply can’t be removed with the non-abrasive touch of dry ice alone. Depending on the many factors of the surface, dry ice + abrasive is usually best for industrial applications such as structural steel of ships, tanks, infrastructure, tanks and pipelines.

When Your Haunted House Needs Dry Ice In Bulk, Call Cee Kay

The old house is little more than a pile of lumber and iron, a forgotten relic of some bygone era. The moon is full and the chilly fall air feels laden with suspense. A low fog rolls in, and the guests waiting to enter the haunted attraction are buzzing with nervous excitement. A haunted house is all about showmanship. You are building up tension, getting your guests to buy in to the illusion, and this come from what they see, hear and feel. When your haunted house wants to set the correct mood, dry ice is an important part of the illusion. This means you need plenty of commercial-grade dry ice on hand. When you need to know where to buy dry ice, Cee Kay is your ideal supplier

How To Make Fog

It is surprisingly easy to create your own haunted effect for whatever spooky environment you create this Halloween. All you need is hot water, protective gloves, 10-15 lbs of dry ice, and a sturdy plastic bucket or container. When gathering your supplies remember that 4-8 gallons of hot water and 10-15 lbs of dry ice will create about 20 minutes of fog. 

 

  1. Fill the sturdy plastic container half full of hot water.
  2. Using protective gloves, carefully place the ice in the water. Fog should start immediately.
  3. Repeat step 2 every 8-10 minutes to maintain the level of fog you need. 
  4. Once the water in the plastic container has cooled the fog will stop being produced.  Return to step 1.

 

To fill a small room, 15-30 lbs of dry ice in two containers will produce fog for 45 minutes to an hour. Larger rooms will need more containers and about 60 lbs of dry ice to produce the same amount. If you plan to make fog outside, make sure you have plenty of dry ice and hot water on hand and remember that any wind or breeze will make your fog dissipate quicker than indoors.

The Key Difference with Dry Ice

With dry ice, you can easily achieve the fog you want. These machines use dry ice that is very cold and warmed water to create a temperature difference that creates a cool fog that gives the feeling of being deep underground or in a spooky cemetery as it stays low to the ground. When you buy dry ice in bulk, you have plenty of fuel for multiple events. 

Cee Kay Supply Is Your Local Dry Ice Source

Dry Ice is important to creating the perfect mood at your haunted attraction. The best way to make sure you have plenty of dry ice for all of your fog machines is to call Cee Kay. Whether you need to keep products cold or are looking to create that wonderfully spooky Halloween atmosphere, our high-quality dry ice is all you need. 

Before You Elevate Your Halloween Party with Dry Ice, Remember These Important Safety Tips:

Dry Ice should always be stored and used within areas with adequate ventilation. Dry Ice sublimates into Carbon Dioxide gas which can pose a suffocation hazard in confined areas.

  • Use only with equipment and storage containers suitable for dry ice. Never store dry ice in a container with an airtight seal as it may burst.
  • Dry Ice is extremely cold and can cause frostbite. Always wear proper protective clothing and avoid contact with exposed flesh.  In case of prolonged contact with skin obtain medical treatment immediately.
  • Dry ice is harmful if eaten or swallowed. If ingested, seek medical treatment immediately.
