Safety & SDS (Safety Data Sheets)
Your safety is our top priority. Whether you’re handling dry ice or working with CO₂, MacGas provides clear guidance and downloadable resources to keep your team protected.
Dry Ice Safety
Dry ice is frozen carbon dioxide at -109°F (-78°C). It’s safe to use with proper precautions:
-
Always wear insulated gloves or use tongs—direct skin contact can cause severe frostbite.
-
Use in well-ventilated areas—as dry ice sublimates, it releases CO₂ gas which can displace oxygen.
-
Never store in airtight containers—buildup of CO₂ gas can cause an explosion.
-
Do not ingest.
-
Keep away from children and pets unless supervised.
CO₂ Safety
Carbon dioxide (CO₂) is widely used in food, beverage, and industrial applications. It is non-flammable but poses risks in enclosed or poorly ventilated spaces.
Precautions:
-
Install CO₂ monitors and alarms in confined spaces (breweries, walk-ins, basements).
-
If an alarm sounds, evacuate immediately and ventilate before re-entry.
-
Avoid entering tanks, coolers, or areas where CO₂ may have pooled without proper testing.
-
Use only trained personnel for tank installation and refills.
Safety & SDS FAQ
Q1. How long does dry ice last?
A1. In a standard insulated cooler, dry ice will last 18–24 hours depending on the size of the pieces and how often the cooler is opened. For longer-lasting performance, limit air exposure and choose larger blocks instead of pellets.
Q2. Is dry ice safe to touch?
A2. No. Dry ice is -109°F (-78°C) and will cause frostbite if touched directly. Always use insulated gloves or tongswhen handling dry ice.
Q3. Can I store dry ice in my freezer?
A3. No. Most household freezers cannot maintain the extreme cold of dry ice. Storing it inside can damage your freezer thermostat and cause it to fail. Always store dry ice in a well-ventilated cooler.
Q4. What should I do if my CO₂ alarm goes off?
A4. Evacuate the area immediately, alert others, and ventilate the space before re-entry. Do not ignore alarms—elevated CO₂ levels can quickly cause dizziness or unconsciousness.
Q5. Do bars and restaurants need CO₂ safety monitors?
A5. Yes. Breweries, bars, and restaurants that use CO₂ tanks or MicroBulk systems should install CO₂ monitoring systems in all confined spaces, especially basements and cooler areas.
Q6. How do I dispose of leftover dry ice safely?
A6. Place the dry ice in a well-ventilated outdoor area and let it sublimate naturally. Never put it in sinks, toilets, or trash cans—it can damage plumbing and cause pressure buildup.
Q7. What should I do in case of a CO₂ supply emergency?
A7. Call MacGas 24/7 at (888) 612-2669. We provide emergency spot loads and short-term bulk CO₂ supply to keep your operations running.
