Overview (read more)

From explosion-proof upright units to ventilated ventilated chambers, our hazardous material cold-storage solutions are crafted to deliver reliable temperature performance, spill containment, and fire safety features. We help you integrate safe storage with facility workflows and regulatory expectations—from chemical labs to vivarium reagent rooms.

Types of Hazardous Materials Cold-Storage

Explosion-Proof Freezers

• Upright and under-counter freezers</strong rated for flammable refrigerants and hazardous environments.
• Sealed electrical enclosures</strong and spark-resistant hardware compliant with NFPA 45/99.
• Automatic lock-out and alarm systems</strong for breach or power failure events.

Flammable & Corrosive Refrigerators

• Ventilated cabinets</strong to safely exhaust vapours from flammable chemicals.
• Seamless corrosion-resistant interiors</strong designed to hold acids, solvents and reagents.
• Temperature range modifiable</strong to suit reagent stability from +2 °C to +8 °C.

Combination Storage Systems

• Integrated freezer/refrigerator units</strong for combined chemical and sample storage in one footprint.
• Modular shelving and containment trays</strong configured for separate chemical segregation.
• Alarm and access control systems</strong to protect restricted materials and support audit reporting.

Key Features & Benefits

Safety & Compliance

• Code-compliant design: meets NFPA 45, OSHA’s Lab Standard, and UL/CSA listed for hazardous liquids and gases.
• Fire-rated cabinets: negative-pressure airflow, self-closing doors and fire-dampered vents.
• VOC exhaust and spill containment systems: minimise risk during chemical storage and emergencies.

Performance & Workflow

• Precise temperature control</strong for both reagent and biological storage in the same environment.
• Auto-lock features</strong and door-open alarms to support inventory control and audit readiness.
• Engineering support: facility layout reviews, utility integration and regulatory documentation from ARES Scientific.

Hazardous Cold-Storage FAQ

What standards apply to hazardous-materials freezers and refrigerators?

Key standards include :contentReference[oaicite:0]{index=0} (laboratory fire protection), :contentReference[oaicite:1]{index=1} (laboratory equipment), and :contentReference[oaicite:2]{index=2}’s Lab Standard (29 CFR 1910.1450). Units should also be listed for flammable/combustible materials and use appropriate refrigerants.

How do I choose between a flammable-rated refrigerator vs explosion-proof freezer?

If you’re storing flammable liquids, choose a ventilated, flammable-rated refrigerator from a reputable manufacturer. For solvents, compressed gases or volatile compounds requiring freezing, choose explosion-proof freezers rated for Class I, Division 2 or equivalent.

Can I store biological samples and flammable chemicals in the same unit?

Generally no, most protocols and accreditation bodies recommend separate cabinets. ARES can help you determine whether a combination storage solution is acceptable under your institutional SOPs.

What routine maintenance is required?

Check door gaskets, verify alarm functionality, inspect ventilation ducts and replace filters/spill trays annually. Also maintain temperature logs and ensure service records align with audit requirements.
